Technical Field

The present application relates to the field of video surveillance technologies, and in particular, to a method and an apparatus for determining video integrity, and a readable storage medium.

Background

Event recording generally refers to linked recording after an event occurs. The current method for determining the integrity of an event record is generally as follows: and acquiring device logs of two events of starting video recording and ending video recording, and then judging whether the event video recording is complete according to the video recording starting time and the video recording ending time in the acquired device logs.

However, in an actual application scenario, since the device logs may not correspond to one recording start time and one recording end time, the device logs including the recording start time and the recording end time cannot be identified by the device. In addition, after the event occurs, the video recording log is not generated under the condition that the video recording equipment fails and the video recording is not linked. Thus, the above method determines inaccurate results.

Disclosure of Invention

The application provides a method and a device for determining the integrity of a video and a readable storage medium, which solve the problem that the determination result in the method for determining the integrity of the video is inaccurate.

In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, the present application provides a method for determining video integrity, where the method is applied to a device for determining video integrity, and the device for determining video integrity acquires state information of a trigger event (including an event start time of the trigger event) and time information of a video file (including a video start time and a video end time of the video file), and determines the integrity of the video file according to the state information and the time information. The triggering event is used for triggering generation of the video file.

In the above solution, the device for determining the integrity of the video recording determines the integrity of the video recording file according to the event start time of the trigger event, the video recording start time of the video recording file, and the video recording end time of the video recording file. The video file in the application is generated by triggering a triggering event, the event starting time of the triggering event represents that the triggering event occurs at the moment, and the video starting time and the video ending time of the video file represent the recording moment of the video file. Therefore, the state information of the trigger event can accurately reflect whether the trigger event occurs, and the time information of the video file can accurately reflect whether the video file is recorded or not when the trigger event occurs. Therefore, the result of the completeness of the video file determined by the method is accurate.

Optionally, the method for determining the integrity of the video file according to the state information and the time information includes: and determining at least two recording moments of the video file according to the video starting moment and the video ending moment of the video file, and determining the integrity of the video file according to the state information and the at least two recording moments.

In the above scheme, the device for determining the integrity of the video record is the recording time of filling the video record file between the video record starting time and the video record ending time. Therefore, when the integrity of the video file is determined according to the at least two recording moments and the state information of the filled video file, each recording moment of the at least two recording moments can be compared with the event starting moment, the problem of mistaken determination (incomplete identification of the complete video file) caused by factors such as network delay and the like when the video starting moment, the video finishing moment and the event starting moment are only compared is solved, and the accuracy of the determined result of the integrity of the video file is improved.

Optionally, the method for determining the integrity of the video file according to the state information and the at least two recording moments includes: and under the condition that the intersection of the event starting moment and at least two recording moments is determined, determining that the video file is complete. And under the condition that the intersection between the event starting moment and at least two recording moments does not exist, determining that the video files are incomplete.

In the above scheme, the determining device for the integrity of the video records intersects the event starting time and at least two recording times, when the intersection exists in the intersection result, the integrity of the video files is determined, and when the intersection does not exist in the intersection result, the incompleteness of the video files is determined. The problem that the determined result is inaccurate when the integrity of the video file is judged according to the video starting time and the video ending time in the equipment log is solved.

The delay parameter is used for representing the minimum recording time length of the video file or the delay video recording time length of the video file. The method for determining the integrity of the video file according to the state information and at least two recording moments comprises the following steps: and determining at least one jitter parameter of the video file according to the event starting time, the event ending time, the delay parameter and the at least two recording times. In the event that it is determined that the at least one jitter parameter includes a target jitter parameter, determining that the video file is complete. And determining that the video file is incomplete when the target jitter parameter is not included in the at least one jitter parameter. The target jitter parameter is a jitter parameter of which the value is less than or equal to a preset threshold value; the jitter parameter is the difference between the duration of the trigger event and the duration of the video file.

In the above scheme, the device for determining the integrity of the video records calculates the difference between the duration of the trigger event and the duration of the video file according to the event starting time, the event ending time, the delay parameter and at least two recording times. The delay parameter in the application is the time length of the delayed video of the video file, and when the trigger event is the transient event, the time length of the delayed video is the recording time length of the video file of the transient event. Therefore, the duration of the trigger event can be accurately calculated according to the event starting time, the event ending time and the delay parameter. Therefore, according to the method and the device, when the integrity of the video file is determined according to the difference between the duration of the trigger event and the duration of the video file, the accuracy of the result of the determined integrity of the video file is further improved.

The target time is the latest time in the time included in all the received state signals.

Detailed Description

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present embodiment, "a plurality" means two or more unless otherwise specified.

Video recording can be generally divided into timer recording and event recording.

Timer recording generally refers to performing a recording task according to a configured timer recording schedule. For example, if the timer recording schedule configured by the user is all-weather recording, the recording device performs 24-hour continuous recording. For another example, if the timer recording schedule configured by the user is monday to friday recording, the recording apparatus executes the recording task at the designated time of the timer recording schedule.

The event recording generally refers to recording in a linked manner after an event (a trigger event according to the embodiment of the present application) occurs. For example, if the trigger event is configured as a movement event occurring in the monitoring area of the image capturing device (image sensor), the video recording device is triggered to execute a video recording task when an object moves in the monitoring area of the image capturing device.

In the process of executing the video recording task, a video recording video (a video recording file according to the embodiment of the present application) is generated. The hard disk failure, the damage of the server operating system, the loss of the configuration data, the error of the network transmission, the instability of the equipment program and other reasons can cause the interruption or the loss of the video file, and for the scene with the requirement of calling the video file (such as an accident), the loss of the video file can cause the loss of persons and property which are difficult to measure. Therefore, the integrity or continuity of the video file is critical.

The current method for determining the integrity of an event video record is generally as follows: and acquiring device logs of two events of starting video recording and ending video recording, and then judging whether the event video recording is complete according to the video recording starting time and the video recording ending time in the acquired device logs. However, in an actual application scenario, since the device logs may not correspond to one recording start time and one recording end time, the device logs including the recording start time and the recording end time cannot be identified by the device. In addition, after the event occurs, the video recording log is not generated under the condition that the video recording equipment fails and the video recording is not linked. Therefore, the above method determines inaccurate results.

Therefore, the embodiment of the application provides a method for determining the integrity of a video. The determining method can determine the integrity of the video file according to the state information of the trigger event (including the event starting time of the trigger event) and the time information of the video file (including the video starting time and the video ending time of the video file). The state information of the trigger event can accurately reflect whether the trigger event occurs or not, and the time information of the video file can accurately reflect whether the video file is recorded or not when the trigger event occurs. Therefore, the determined result of the integrity of the video file is more accurate.

The method for determining the video integrity provided by the embodiment of the application can be suitable for a system for determining the video integrity. Fig. 1A and 1B show the structure of the system for determining the integrity of a video recording. As shown in fig. 1A and 1B, the system for determining video recording integrity provided by the embodiment of the present application includes a video recording device 10, a server 11, a device 12 for determining video recording integrity, and a sensor 13.

The sensor 13 may be various sensors, such as an image sensor, a position sensor, a liquid level sensor, an energy consumption sensor, a speed sensor, an acceleration sensor, an infrared sensor, and the like, and the specific type of the sensor 13 is related to the type of the trigger event, and if the trigger event is configured to generate a movement event, the sensor 13 may be a position sensor, a speed sensor, and the like, which is not limited in this disclosure.

The server 11 and the video integrity determination device 12 may be integrated into one device, or may be located in two devices independent from each other, and the embodiment of the present application does not limit the positional relationship between the server 11 and the video integrity determination device 12.

When the server 11 and the video integrity determination device 12 are integrated into one device, the step of the video integrity determination device 12 obtaining the state information of the trigger event from the server 11 is an internal interaction in the one device.

The video integrity determination device 12 is configured to obtain the state information of the trigger event and the time information of the video file, and determine the integrity of the video file according to the state information and the time information. When the server 11 and the video integrity determination device 12 are integrated into one device, the step of the video integrity determination device 12 obtaining the state information of the trigger event from the server 11 is an internal interaction in the one device.

In the embodiment of the present application, the functions implemented by the video recording device 10, the server 11, the recording integrity determination device 12, and the sensor 13 are different because the software programs stored in the memory 22 are different for the video recording device 10, the server 11, the recording integrity determination device 12, and the sensor 13.

The following describes a method for determining video integrity according to an embodiment of the present application with reference to the accompanying drawings.

As shown in fig. 3, the method for determining video integrity according to the embodiment of the present application includes the following steps.

Step 31: the video integrity determination device acquires state information of the trigger event and time information of the video file.

The trigger event is used for triggering generation of the video file, the state information comprises event starting time of the trigger event, and the time information comprises video starting time and video ending time of the video file.

Specifically, referring to fig. 3 and as shown in fig. 4, the method for the video integrity determination device to obtain the status information of the trigger event includes:

step 30: the video integrity determination device receives the status signal and determines status information based on the status signal.

First, the video integrity determination device configures parameters such as event video recording plans and delay parameters for the video integrity determination system.

Specifically, after an event video recording plan is configured for the video integrity determination system, in the linear time of the event video recording plan, if a trigger event occurs, the time of each device in the video integrity determination system falls within the linear interval. After the delay parameters are configured for the system for determining the integrity of the video, if a trigger event occurs, the video equipment prolongs the corresponding recording time according to the delay parameters in the process of recording the video file.

And then, in the process of triggering a preset trigger event, the video equipment records a video file and sends a state signal to the server. The state signal comprises the state of the trigger event and the time corresponding to the state of the trigger event.

Specifically, in terms of time dimension, the trigger events are generally divided into transient events and impulse events, the transient events are events with a duration of 0(t ═ 0), and the impulse events are events with a duration of t (t > 0), and therefore, the transient events are also special impulse events. The states of the trigger event generally include an event start state, an event duration state, and an event end state. Thus, the state of the transient event includes an event start state and an event end state. The states of the impulse event include an event start state, an event duration state, and an event end state.

And according to the event video recording plan configured by the system determined by the video integrity, linking the video equipment to record the video file when the preset trigger event occurs randomly. The method comprises the steps that the video recording equipment sends a first state signal to a server at the moment when a trigger event occurs (when the video recording equipment is not provided with pre-recording, the moment when the video recording equipment starts recording a video recording file is also the moment), wherein the first state signal comprises an event starting state and an event starting moment corresponding to the event starting state. And sending a second state signal to the server at preset time intervals in the process of continuing the trigger event so as to maintain the heartbeat. The second state signal includes an event duration state and an event duration time corresponding to the event duration state. And at the moment when the trigger event is finished, the video recording equipment sends a third state signal to the server, and the video recording file is obtained after the corresponding recording time length is prolonged according to the configured delay parameter. The third state signal includes an event end state and an event end time corresponding to the event end state.

In the above scheme, the video recording device records the video recording file in the process of triggering the trigger event, and sends the status signal to the server, so that the video integrity determination device determines the integrity of the video recording file according to the time information of the video recording file and the status information of the trigger event. The problem that the determined result is inaccurate when the integrity of the video file is judged according to the video starting time and the video ending time in the equipment log is solved.

The server then receives the status signal and determines status information based on the status signal.

Specifically, when the server determines that the status signal includes the end status, the server determines a time corresponding to the end status as the event end time. In a case where it is determined that the status signal does not include the end status, it is determined that the latest time among the times included in all the received status signals is the event end time.

Optionally, the server determines that the latest time among the times included in all the received status signals is the event end time when it is determined that the status signals do not include the end status and the preset time duration is exceeded. The preset time length is a preset numerical value, for example, a default value, or a numerical value which is an integral multiple of a preset time interval, or a numerical value which is written by a relevant person according to an actual situation, which is not limited in the present application.

In the above scheme, the server receives the status signal and determines the status information according to the status signal, so that the subsequent video integrity determination device determines the integrity of the video file according to the status information.

And finally, the video integrity determination device acquires the state information of the trigger event and the time information of the video file.

Specifically, when there is a need (including a need time period) for determining the integrity of the video, the state information of the trigger event in the need time period is called, and the video file in the need time period is acquired from the video device, so as to obtain the time information of the video file.

Further, when the demand time period includes a plurality of trigger events, the video integrity determination device calls the state information of the plurality of trigger events, and acquires a plurality of video files in the demand time period from the video device to obtain time information of the plurality of video files.

Step 32: the video integrity determination device determines the integrity of the video file according to the state information and the time information.

Specifically, the device for determining the integrity of the video records counts the video recording start time and the video recording end time corresponding to each video recording file in the required time period, and counts the event start time of each trigger event in the required time period. And then, the determining device of the video integrity makes an intersection of the event starting time of each trigger event in the required time period and the video starting time and the video ending time corresponding to each video file in the required time period. And when determining that the starting time of the first event and the video starting time and the video ending time corresponding to each video file in the required time period are not intersected, determining that the video files of the trigger event corresponding to the starting time of the first event are incomplete. The first event starting time is the event starting time of any trigger event in the demand time period. Then, the video integrity determination device determines the number of the start time of the first event, which is the number of times of video file loss in the required time period.

For example, fig. 5 is a timing chart for determining the integrity of a video file according to an embodiment of the present application. As shown in fig. 5, between time a and time p, 7 trigger events and 6 video files are included. Wherein, the event starting time and the event ending time (expression form: event starting time-event ending time) of the 7 triggering events are respectively as follows: time (a-b), time (c-d), time (e-g), time (h-i), time (j-l), time (m-n), and time (o-p). The video recording start time and the video recording end time (expression form: video recording start time-video recording end time) of the 6 video recording files are respectively as follows: time (a-b), time (c-d), time (e-f), time (h-i), time (j-k), and time (m-n).

Then, when the required time period is from the time a to the time p, the determining device for video integrity respectively sets the event start times of the 7 trigger events as: the time a, the time c, the time e, the time h, the time j, the time m, the time o, and the video starting time and the video ending time corresponding to each video file in the required time period are respectively as follows: and (c) intersecting (moment a-moment b), (moment c-moment d), (moment e-moment f), (moment h-moment i), (moment j-moment k) and (moment m-moment n) to obtain moment o, wherein the moment o does not intersect with the video recording starting moment and the video recording ending moment corresponding to the video recording file in the required time period, and then the video recording file corresponding to the moment o is determined to be lost. The number of times of loss of the video file in the required time period is 1.

In the above solution, the device for determining the integrity of the video recording determines the integrity of the video recording file according to the event start time of the trigger event, the video recording start time of the video recording file, and the video recording end time of the video recording file. The video file in the application is generated by triggering a triggering event, the event starting time of the triggering event represents that the triggering event occurs at the moment, and the video starting time and the video ending time of the video file represent the recording moment of the video file. Therefore, the state information of the trigger event can accurately reflect whether the trigger event occurs, and the time information of the video file can accurately reflect whether the video file is recorded or not when the trigger event occurs. Therefore, the result of the completeness of the video file determined by the method is accurate.

Optionally, the determining device for video recording integrity determines the integrity of the video recording file according to the state information and the time information, and may further include the following implementation manners.

The implementation mode is as follows: referring to fig. 3, as shown in fig. 6, the method includes:

step 32 a: the device for determining the integrity of the video records determines at least two recording moments of the video files according to the video recording starting moment and the video recording ending moment of the video files.

Specifically, the video files are linked videos after the trigger event occurs, so the video files in the required time period are discrete line segment sequences in the time dimension, and no correlation exists between the line segment sequences. For example, the time information of a plurality of video files in the required time period is represented as R_(x)＝{T_x-T_x-1,T_x-1-T_x-2,T_x-2-T_x-3,…,T_x-m-T_x-m-1X is more than or equal to 0, m is more than or equal to 0, wherein R_(x)Time information T representing a plurality of video files in a required time period_x-m-1For the recording start time, T, of the mth recording file among the plurality of recording files_x-mThe recording end time of the mth recording file in the plurality of recording files.

And then, the video integrity determination device fills the time for the time information of each video file in the required time period. Specifically, the time in the time information of each video file in the default required time period is a time sequence set composed of uniformly distributed time points, and the time is automatically filled in the time information of each video file.

For example, the time information of the mth video file among the plurality of video files is represented by R_(m)＝{T_x-m-T_x-m-1In which T is_x-m-1For the recording start time, T, of the mth recording file_x-mThe recording end time of the mth recording file. The moment in the time information of the mth video file in the default required time period of the video integrity determining device is a time sequence set T consisting of uniformly distributed time points_footage(x) And T is_footage(x)＝{T_ts(ω)|T_ts(ω)＝T_x-m-1+ k ω }, x is not less than 0, m is not less than 0, wherein T_ts(ω) is a linear function of the time instants in the set of time instant sequences, k is a sequence parameter and is a complex number, ω represents the number of time instants in the set of time instant sequences and is an integer, T_x-m-1+ k ω is less than or equal to T_x-m。

Wherein the time in the time information is accurate to seconds(s). Thus, the time information R of a plurality of video files in the required time period_(xCan be represented as T_footageSet of (ω), i.e. R_(x)＝{T_footage(1),T_footage(2),…,T_footage(x)},x≥0。

Step 32 b: the video integrity determination device determines whether an intersection exists between the event starting time and at least two recording times.

Specifically, the video integrity determination device retrieves state information of trigger events in the required time period, and determines a set of event start times of a plurality of trigger events in the required time period according to the state information of the trigger events.

For example, a set of event start times, denoted P, for a plurality of trigger events within a demand period_(y)，P_(y)＝{T_y,T_y+1,T_y+2,T_y+3,…,T_y+n},n≥0，T_y+nIndicating the start of a plurality of eventsThe nth event start time in the set. Wherein the time in the set of event start times is accurate to seconds(s).

Then, the device for determining the integrity of the video records sets P of the event starting moments of a plurality of trigger events in the required time period_(y)Time information R of a plurality of video files in a required time period_(x)And performing intersection, and judging whether the event starting moment and the at least two recording moments have intersection or not.

In the above scheme, the device for determining the integrity of the video record is the recording time of filling the video record file between the video record starting time and the video record ending time. Therefore, when the integrity of the video file is determined according to the at least two recording moments and the state information of the filled video file, each recording moment of the at least two recording moments can be compared with the event starting moment, the problem of mistaken determination (incomplete identification of the complete video file) caused by factors such as network delay and the like when the video starting moment, the video finishing moment and the event starting moment are only compared is solved, and the accuracy of the determined result of the integrity of the video file is improved.

Step 32b 1: and the video integrity determining device determines that the video file is complete under the condition of determining that the intersection exists between the event starting time and at least two recording times.

Specifically, assume that N represents P within the demand period_(y)And R_(x)If N is equal to N, it is determined that the video file in the required time period is complete. Where n represents the number of event start times within the demand period (i.e., the number of trigger events within the demand period).

Step 32b 2: and the video integrity determining device determines that the video files are incomplete under the condition that the event starting time and at least two recording times do not have intersection.

Specifically, assume that N represents P within the demand period_(y)And R_(x)If N is less than N, the video files in the required time period are determined to be incomplete, and the number of lost video files is N-N. Where n represents the start of an event within a demand periodThe number of time instants (i.e. the number of trigger events within the demand period).

In the above scheme, the determining device for the integrity of the video records intersects the event starting time and at least two recording times, when the intersection exists in the intersection result, the integrity of the video files is determined, and when the intersection does not exist in the intersection result, the incompleteness of the video files is determined. The problem that the determined result is inaccurate when the integrity of the video file is judged according to the video starting time and the video ending time in the equipment log is solved.

The implementation mode two is as follows: referring to fig. 3, as shown in fig. 7, the method includes:

step 32 a: the device for determining the integrity of the video records determines at least two recording moments of the video files according to the video recording starting moment and the video recording ending moment of the video files.

Specifically, the method for determining at least two recording moments of a video file by the video integrity determination device is the same as the method for determining at least two recording moments of a video file in the first implementation mode, that is, the time information R of a plurality of video files in a required time period_(x)Can be represented as T_footageSet of (ω), i.e. R_(x)＝{T_footage(1),T_footage(2),…,T_footage(x) And x is more than or equal to 0. And will not be described in detail herein.

Step 32 c: the device for determining the integrity of the video determines at least one jitter parameter of the video file according to the event starting time, the event ending time, the delay parameter and the at least two recording times, and judges whether the at least one jitter parameter comprises a target jitter parameter.

The jitter parameter is the difference between the duration of the trigger event and the duration of the video file, and the target jitter parameter is the jitter parameter with the value smaller than or equal to the preset threshold value. The preset threshold is a preset numerical value, for example, a default value, or a numerical value written by a relevant person according to an actual situation, which is not limited in the present application.

Specifically, the determining device for video integrity retrieves an event start time, an event end time and a delay parameter of a trigger event in a required time period, and determines a set of target end times of a plurality of trigger events in the required time period according to the event start time, the event end time and the delay parameter of the trigger event, wherein the target end time is an end time of a video file calculated according to state information of the trigger event.

For example, if the trigger event is a transient event, the set of target end times within the demand period is denoted Ptransient_(y)，Ptransient_(y)＝P_(y)+t_delay＝{T_y+t_delay,T_y+1+t_delay,…,T_y+n+t_delay},n≥0，T_y+n+t_delayIndicating the nth target end time, t, in the set of target end times_delayRepresenting a delay parameter. Wherein the time in the set of target end times is accurate to seconds(s).

Thus, at least one jitter parameter of each video file in the demand time period is determined according to the set of target end times and at least two recording times in the demand time period.

Specifically, the jitter parameter of the trigger event satisfies the formula β ═ T_start-T₁|+|T_end+t_delay-T₂Where β represents the jitter parameter of the trigger event, T_startIndicating the event start time, T, of the trigger event_endEvent end time, t, representing a trigger event_delayDenotes a delay parameter, T₁Indicating the first recording time, T₂Indicating a second recording time; the first video recording time and the second video recording time are both time information R_(x)Time of day (c). Since the transient event has a duration of 0(T ═ 0), the jitter parameter of the transient event may also be represented as β ═ T_start-T₁|+|T_start+t_delay-T₂L. In particular, T₁Time and T₂The time can be any time in the time information of the video file corresponding to the instant event, so that at least one jitter parameter of the video file corresponding to the instant event is obtained.

If the trigger event is a pulse event, the set of target end times within the required time period is denoted as pimplesive_(y)，Pimpulsive_(y)＝P_(y)+t_duration+t_delay＝{T_y+t_duration+t_delay,T_y+1+t_duration+t_delay,…,T_y+n+t_duration+t_delay},n≥0，T_y+n+t_duration+t_delayIndicating the nth target end time, t, in the set of target end times_delayDenotes a delay parameter, t_durationRepresents the duration of the trigger event, and t_duration＝T_end-T_start，T_endEvent end time, T, representing a trigger event_startIndicating the event start time of the triggering event. Wherein the time in the set of target end times is accurate to seconds(s).

Thus, at least one jitter parameter of each video file in the demand time period is determined according to the set of target end times and at least two recording times in the demand time period.

Specifically, the jitter parameter of the trigger event satisfies the formula β ═ T_start-T₁|+|T_end+t_delay-T₂|＝|T_start-T₁|+|T_start+t_duration+t_delay-T₂L. Where β represents the jitter parameter of the trigger event, T_startIndicating the event start time, T, of the trigger event_endEvent end time, t, representing a trigger event_delayDenotes a delay parameter, t_durationIndicating the duration of the trigger event (if the trigger event is a transient event, t)_durationIs 0), T₁Indicating the first recording time, T₂Indicating a second recording time; the first video recording time and the second video recording time are both time information R_(x)Time of day (c). In particular, T₁Time and T₂The value of the moment is the same as that of the instantaneous event, and any moment in the time information of the video file corresponding to the pulse event can be taken, so that at least one jitter parameter of the video file corresponding to the pulse event can be obtained.

Then, the video integrity determination means determines whether or not the target jitter parameter is included in the plurality of jitter parameters.

Step 32c 1: the video integrity determination means determines that the video file is complete when it is determined that the target jitter parameter is included in the at least one jitter parameter.

Step 32c 2: the video integrity determination means determines that the video file is incomplete when it is determined that the target jitter parameter is not included in the at least one jitter parameter.

Illustratively, in the timing diagram of fig. 5 for determining the integrity of video files, 7 trigger events (including impulse events and transient events) and 6 video files are included between time a and time p. Wherein, the event starting time and the event ending time (expression form: event starting time-event ending time) of the 7 triggering events are respectively as follows: time (a-b), time (c-d), time (e-g), time (h-i), time (j-l), time (m-n), and time (o-p). The video recording start time and the video recording end time (expression form: video recording start time-video recording end time) of the 6 video recording files are respectively as follows: time (a-b), time (c-d), time (e-f), time (h-i), time (j-k), and time (m-n).

Then, when the required time period is from time a to time p, the delay parameter is 0, and the preset threshold is 0, the jitter parameter between the corresponding trigger event and the corresponding video file within time a to time p is as follows. In this case, the target jitter parameter is a jitter parameter whose value is smaller than or equal to the preset threshold, and the video integrity determination device determines that the video file is complete when determining that at least one of the jitter parameters includes the target jitter parameter.

Time a-b: the duration of the trigger event is b-a, the duration of the video file is b-a, the minimum jitter parameter corresponding to the video file with the duration of b-a is | a-a | + | b-b | ═ 0, and the video file at the moment a and the moment b is lossless.

c time-d time: the duration of the trigger event is d-c, the duration of the video file is d-c, the minimum jitter parameter corresponding to the video file with the duration of d-c is | c-c | + | d-d | ═ 0, and the video file at the moment c-d is lossless.

Time e-time g: the duration of the trigger event is g-e, the duration of the video file is f-e, the minimum jitter parameter corresponding to the video file with the duration of f-e is | e-e | + | g-f | -g-f > 0, the video file at the c moment-d moment is lost, and the incomplete times of the video file in the required time period are added by 1 time.

Time h-time i: the duration of the trigger event is i-h, the duration of the video file is i-h, the minimum jitter parameter corresponding to the video file with the duration of i-h is | h-h | + | i-i | ═ 0, and the video file at the h moment-i moment is lossless.

Time j-time l: the duration of the trigger event is l-j, the duration of the video file is k-j, the minimum jitter parameter corresponding to the video file with the duration of k-j is | j-j | + | l-k | -l-k | > 0, the video file at the time j and the time l is lost, and the incomplete times of the video file in the required time period are added by 1 time.

Time m-time n: the duration of the trigger event is n-m, the duration of the video file is n-m, the minimum jitter parameter corresponding to the video file with the duration of n-m is | m-m | + | n-n | ═ 0, and the video file at the moment of m and the moment of n is lossless.

Time o-p: the duration of the trigger event is p-o, the duration of the video file is 0, the minimum jitter parameter corresponding to the video file with the duration of 0 is | o-0| + | p-0| -, o + p > 0, the video file at the time of o moment-p is lost, and the incomplete times of the video file in the required time period are added by 1 time.

In summary, in the timing chart of fig. 5, the number of incomplete video files in the required time period is 3.

Optionally, the video integrity determination device determines that the video files in the required time period are incomplete and sends an alarm when the number of times of the lost video files is greater than i times in the required time period.

In the above scheme, the device for determining the integrity of the video records calculates the difference between the duration of the trigger event and the duration of the video file according to the event starting time, the event ending time, the delay parameter and at least two recording times. The delay parameter in the application is the time length of the delayed video of the video file, and when the trigger event is the transient event, the time length of the delayed video is the recording time length of the video file of the transient event. Therefore, the duration of the trigger event can be accurately calculated according to the event starting time, the event ending time and the delay parameter. Therefore, according to the method and the device, when the integrity of the video file is determined according to the difference between the duration of the trigger event and the duration of the video file, the accuracy of the result of the determined integrity of the video file is further improved.
