Technical Field

The invention relates to the technical field of psychological analysis, in particular to a psychological crisis intervention auxiliary system.

Background

Psychological crisis refers to the psychological response of an individual when the individual encounters an emergency or faces significant frustration and difficulty, and the individual cannot avoid the psychological response and cannot solve the psychological response in a resource and stress manner. Students in schools usually do not have too much life experience, and are easy to have psychological crisis when encountering the problem of interpersonal communication, even violence tendency and overstimulation behavior.

In the aspect of schools, high-risk groups which are easy to generate violence tendency in students need to be identified, and corresponding measures are taken timely. For example, document CN106618608A discloses a method for monitoring dangerous persons based on video psychophysiological parameters, which includes the steps of: acquiring video information of a tested person; processing the video information to generate a bio-signal containing information relating to the degree of risk; and obtaining the danger degree of the tested person according to the vibration frequency and/or the vibration amplitude of the biological signal.

Through the process of capturing video image information, biological signals of students are obtained, and high risk groups can be easily detected. However, this evaluation is subjective and these high risk groups are only likely to develop a tendency to violence and do not necessarily conduct violence. That is to say, whether the student will produce violence tendency can not be objectively evaluated, and the real high-risk group can not be accurately and effectively identified through the method, so that the early warning information can be effectively pushed.

Disclosure of Invention

The invention provides a psychological crisis intervention auxiliary system, which solves the technical problem that the prior art cannot accurately and effectively identify real high-risk groups so as to effectively push early warning information.

The following is further detailed by the specific embodiments:

example 1

The embodiment of the psychological crisis intervention auxiliary system of the invention is basically as shown in the attached figure 1, and comprises:

the acquisition module is used for acquiring the monitoring video of the target person in real time;

the pre-judging module is used for analyzing the monitoring video of the target person, generating a biological signal containing the danger degree, and judging whether the target person is a potential high-risk object according to the biological signal: if the target person is not a potential high-risk object, judging that the target person is not a high-risk person without pushing early warning information; on the contrary, if the target person is a potential high-risk object, sending an instruction to the re-judgment module for re-judgment;

and the re-judgment module is used for analyzing the monitoring video of the target personnel, acquiring the action track of the target personnel and judging whether violent action occurs to the target personnel according to the action track: if the target person does not have violent action, judging that the target person is not a high-risk person, and not pushing early warning information; on the contrary, if the target person has violent action, the target person is judged to be a high-risk person, the early warning information needs to be pushed, and an instruction is sent to the pushing module to push the early warning information;

and the pushing module is used for pushing the early warning information.

In this embodiment, the acquisition module is a camera, and the prejudging module, the prejudging module and the pushing module are all integrated on a server, and the functions of the acquisition module, the prejudging module and the pushing module are realized through software/programs/codes.

The specific implementation process is as follows:

and S1, the acquisition module acquires the monitoring video of the target personnel in real time.

In this embodiment, a student in a classroom is a target person, and the acquisition module is a camera, is installed in the classroom, acquires a surveillance video of the student in the classroom in real time, and transmits the acquired surveillance video to the server.

S2, analyzing the monitoring video of the target person by the pre-judging module, generating a biological signal containing the danger degree, and judging whether the target person is a potential high-risk object according to the biological signal: if the target person is not a potential high-risk object, judging that the target person is not a high-risk person without pushing early warning information; otherwise, if the target person is a potential high-risk object, sending an instruction to the re-judgment module for re-judgment.

After the server receives the monitoring video, the pre-judging module analyzes the monitoring video to generate a biological signal containing the danger degree, and judges whether a potential high-risk object exists in the student according to the biological signal. Specifically, the prejudgment module comprises an acquisition unit, a generation unit, a determination unit and a judgment unit, and the acquisition unit is used for acquiring the monitoring video of the student from the server. Then, the generation unit processes the monitoring video to generate a biological signal related to the degree of risk. For example, facial images of students in the monitoring video are extracted, and the change rule of capillary blood vessel congestion during respiration is detected, so that the heart rate and the blood oxygen concentration of the students can be obtained; the phase difference of the blood flow velocity of the human body part is detected, the blood pressure difference of the students can be obtained, and the method can be implemented by referring to the prior art.

Then, the determining unit determines the risk degree of the student according to the vibration frequency of the biological signal, for example, the vibration frequency of the blood oxygen concentration is 10-20 times/no risk, 20-30 times/low risk, 30-50 times/medium risk. Or determining the danger degree of the target personnel according to the vibration amplitude of the biological signal, for example, the heart rate of a normal person is generally 60-100 times/minute, 60-100 times/minute has no danger, 100-120 times/minute has low danger, and 120-150 times/minute has medium danger. Or, the risk degree of the target person is determined according to the vibration amplitude and the vibration frequency of the biological signal, for example, when the vibration frequency of the blood oxygen concentration is 20 to 30 times/minute and the heart rate is 100 to 120 times/minute, the risk is determined to be low.

And finally, judging whether the student is a potential high-risk object or not by the judging unit according to the danger degree: if the danger degree of the students is no danger, the students are judged not to be potential high-risk objects or high-risk personnel, and early warning information does not need to be pushed; on the contrary, if the danger degree of the student is low-degree danger and moderate danger, the student is judged to be a potential high-risk object and possibly a high-risk person, and at the moment, an instruction is sent to the re-judgment module for re-judgment.

S3, analyzing the monitoring video of the target person by the re-judging module, acquiring the action track of the target person, and judging whether violent action occurs to the target person according to the action track: if the target person does not have violent action, judging that the target person is not a high-risk person, and not pushing early warning information; on the contrary, if the target person has violent action, the target person is judged to be a high-risk person, the early warning information needs to be pushed, and an instruction is sent to the pushing module to push the early warning information.

And after the re-judgment module receives the re-judgment instruction, analyzing the monitoring video of the target person to obtain the action track of the target person, and judging whether violent action occurs to the target person according to the action track. Specifically, the re-judging module includes: the system comprises an extraction unit, a track unit and a judgment unit, wherein the extraction unit is used for extracting the monitoring video of a student.

Then, the track unit analyzes the monitoring video of the student to obtain the action track of the student. The method comprises the following specific steps: firstly, acquiring a pixel point set occupied by a student in a video image by adopting a target detection algorithm; secondly, acquiring the position and the size of the student in the video image by adopting a target extraction algorithm according to the pixel point set; thirdly, identifying the number of effective targets and color texture characteristics in the video image by adopting an effective target characteristic identification algorithm according to the targets extracted from the video image; and fourthly, acquiring the action track of each effective target in the video image by adopting a target motion tracking algorithm.

Finally, the judging unit judges whether the student has violent movement according to the movement track, in this embodiment, the movement track of the student is compared with a preset violent movement track: if the similarity between the action track of the student and the preset violent action track is smaller than a preset threshold value, judging that the student does not have violent action, and the student is not a high-risk person and does not need to push early warning information; on the contrary, if the similarity between the action track of the student and the preset violent action track is larger than or equal to the preset threshold value, the student is judged to have violent action, the student is a high-risk person and needs to push early warning information, and an instruction is sent to the pushing module to push the early warning information.

S4, the pushing module pushes the early warning information.

After receiving the instruction of sending the early warning information, the pushing module sends information of 'having a state in a classroom and please process rapidly' to a security department of the school.

Example 2

The difference from the embodiment 1 is that the re-judgment module further comprises a tracking unit, an object unit and an evaluation unit, and after the student is judged to be a high-risk person, firstly, the tracking unit tracks and monitors the target person to pay attention to the situation development condition; then, the object unit determines an object of violent action of the target person, and the evaluation unit evaluates the violence level according to the action track variation amplitude of the target person so as to determine a proper processing mode; and finally, the pushing module pushes early warning information according to the violence level, and the staff take corresponding measures according to the violence level, such as oral education, written review or execution of record points according to school regulations.

Example 3

The difference from the embodiment 2 is only that the role recognition is performed on the student through the interactive inquiry, namely, whether the student is mild or aggressive is determined; wherein, mild students are cool and quiet in case of accidents, are not easy to excited, and have small emotional fluctuation; the radical students are motivated by accidents, are easy to excited and have large emotional fluctuation.

In this embodiment, the server is also provided with a microphone and FaceReader software, and asks students some questions by a guiding method, for example, "when seeing that a friend is beaten by a bady, should the friend rush to help, or alarm? "; meanwhile, the camera shoots the photos of the facial expressions of the students when answering the questions, the photos are sent to the server, and FaceReader software analyzes the facial expressions of the students.

FaceReader software can automatically analyze the facial expressions of students: if the answer of the student is 'alarm' and the facial expression is 'pleasure' or 'natural', the student is cool and quiet in meeting, not easy to excite, small in emotion fluctuation and mild; on the contrary, if the answer of the student is ' rush to help, and the facial expression is ' disgust ', ' anger ' or ' slight libi ', the student is motivated by a chance, is easy to excite, has large emotion fluctuation, and is an aggressive student, the student should be monitored intensively so as to assist psychological intervention in time.
