Technical Field

The present application relates to the field of computer technologies, and in particular, to a traffic data transmission method, a traffic data transmission device, an electronic device, and a storage medium.

Background

At present, on a highway, due to the fact that the driving speed of vehicles is very high, once collision occurs, consequences are hard to imagine, behaviors in the highway process, such as vehicles running backwards, throwing, pedestrians running on lanes and the like, need to be monitored, and otherwise, serious traffic accidents are caused.

For the camera, the camera is divided into a camera which can not rotate at an angle and a camera which can rotate at an angle. For a camera which can not rotate at an angle, an existing video content monitoring method is to analyze a moving track of a vehicle in a video and determine whether the vehicle drives in a wrong direction or not by combining an installation angle of the camera. For the camera with a rotatable angle, the angle of the camera is adjusted by sending a control command to a holder provided with the camera through a control platform. When monitoring the camera capable of rotating the angle, a control instruction sent to the holder needs to be acquired to determine the shooting angle of the camera, and the moving track of the vehicle in the video data is analyzed to determine whether the vehicle drives in the wrong direction or not.

However, the shooting angle of the camera is determined according to the control instruction sent to the pan-tilt, and due to the fact that transmission time exists between the camera and the control platform, video information is prone to being not corresponding to the shooting angle of the camera, and the problem of inaccurate analysis is prone to being caused.

For example, it is possible to monitor whether motor vehicles in urban roads are driving in the wrong direction, whether pedestrians are walking to the right, and whether pedestrians run red lights.

The tripod head is a supporting device for mounting and fixing the camera, and comprises a fixed tripod head and an electric tripod head, wherein the horizontal and pitching angles of the equipment can be adjusted to achieve the required working posture after the camera is mounted on the fixed tripod head, and then the adjustment mechanism can be locked to finish mounting; the electric holder can be understood as a motor device capable of adjusting the shooting angle of the camera, and the electric holder can adjust the shooting angle of the camera according to the instruction of the application processing equipment, so that the image acquisition equipment can scan and shoot in a larger range.

The streaming media server refers to a server for streaming media transmission, storage and management, and may be a server or a cluster formed by a plurality of servers, so as to be able to acquire data streams of acquired images, videos and the like from an image acquisition device such as a camera and transmit corresponding data streams according to the requirements of an application processing device.

The application processing device can perform required processing based on the streaming media data, such as playing video data such as surveillance video, performing processing based on technologies such as Artificial Intelligence (AI) calculation, computer vision, and the like, such as target recognition. The application processing device can be a server, and can also be an electronic device such as a mobile phone, a tablet computer, a computer and the like.

The image acquisition equipment is located at an acquisition end, the streaming media server is located at a server end, the application processing equipment can be located at an application end, the application processing end and the streaming media can be arranged at a service side, or located at one side of the image acquisition equipment, or arranged at a client side according to requirements, and the like, and the image acquisition equipment is specifically arranged according to the requirements.

Although the angle of the camera can be adjusted by the pan-tilt, the adjustment of the angle of the camera can also change the content in the shot video. In order to accurately analyze and display the pictures shot by the camera, the direction sensor is arranged for the camera, so that the direction information such as the rotation direction of the camera can be sensed through the direction sensor, the direction information and the video data shot by the camera are encoded into the encoded video stream, and the encoded video stream is transmitted to the streaming media server. Then, in the application processing of the coded video stream, the video data and the corresponding shooting direction information can be determined, so that the video data can be more accurately displayed, analyzed and the like based on the direction information. The present embodiment packs and transmits the video data and the corresponding direction information, so as to obtain a more accurate analysis result.

In the process of installing the image acquisition equipment, the camera is installed on the cloud platform, and the cloud platform and the camera can be connected through a first serial port. When the image acquisition equipment is collecting data, the angle of its camera is adjustable, can send the direction adjustment instruction and transmit for the camera, and the camera transmits the direction adjustment instruction for the cloud platform through first serial ports, and wherein the direction adjustment instruction can be sent by application processing equipment, like supervisory control equipment etc.. Specifically, the camera receives a direction adjustment instruction for the camera; the direction adjusting instruction is transmitted to the cloud platform through the first serial port, and the cloud platform responds to the direction adjusting instruction to adjust the shooting angle of the camera. The camera is connected with the cradle head through the first serial port, the direction adjusting instruction of the camera can be transmitted to the cradle head, and therefore the shooting angle of the camera, such as the horizontal angle and the pitch angle, can be adjusted by the cradle head, and the monitoring range of the camera is adjusted. The first serial port can be understood as a serial port, which can also be called a serial interface, a serial communication interface or a serial communication interface, and the serial port is an expansion interface adopting a serial communication mode.

The embodiment of the application sets a direction sensor in the camera, so that in step 102, the direction information of the camera is acquired according to the direction sensor.

The orientation sensor, which may also be referred to as an electronic compass, may be integrated on the main board of the image capturing device. The electronic compass can be divided into a plane electronic compass and a three-dimensional electronic compass according to the inclination angle compensation mode, and can also be divided into a magnetoresistive effect sensor, a hall effect sensor, a fluxgate sensor and the like according to the sensor type.

The direction information can be understood as direction angle information of the shooting direction of the camera, such as data of direction angles and the like. The direction information may be acquired periodically or after the camera angle is adjusted. In some alternative embodiments, step 102 comprises: acquiring direction information of the camera regularly according to the direction sensor; or, under the condition that the camera rotates, acquiring direction information of the camera after the rotation according to the direction sensor. In one example, the interval duration may be preset in the image capturing device, and the image capturing device may acquire the direction information from the direction sensor at intervals of the interval duration. In some other examples, the image capture device transmits the direction adjustment command to the cradle head after receiving the direction adjustment command, and the cradle head adjusts the angle of the camera in response to the direction adjustment command, and then the direction sensor can sense the adjustment of the angle of the camera, so as to obtain the corresponding direction information and transmit the direction information back to the image capture device, such as the camera. By acquiring the direction information at fixed time or after the camera finishes rotating, more accurate direction information can be obtained.

After the shooting angle of the camera is adjusted by the holder, the direction sensor can sense and acquire the direction information of the camera. In still other embodiments, step 102 includes: sensing the adjustment of the cloud platform to the camera according to a direction sensor to obtain the direction information; and receiving the direction information transmitted by the direction sensor through the second serial port. After the shooting angle of the camera is adjusted by the holder, the direction angle of the direction sensor is changed, and the direction sensor can sense corresponding direction information at the moment, so that the direction information transmitted to the camera is regularly or sensed through the second serial port under the condition that the direction information is changed. The second serial port is also a serial port.

In this embodiment of the application, the video data collected by the lenses of some cameras may be high-definition video data, for example, the resolution may be higher than 1280 × 720. Therefore, before transmitting the video data shot by the camera, the camera needs to encode and compress the video data to reduce the bandwidth occupied by the transmission process, and certainly, the data collected by the non-high-definition camera can also be encoded and compressed, and the encoding processing can be unrelated to the resolution of the camera and is determined by combining with the specific application requirements. In step 104, according to the video data shot by the camera, a corresponding encoded video stream is determined, and the direction information is added to the encoded video stream. The image acquisition equipment can compress and encapsulate video data to obtain an encoded video stream, add the direction information to the encoded video stream, and then pack the encoded video stream added with the direction information to obtain the encoded video stream added with the direction information.

In some alternative embodiments, step 104 may include: compressing the video data shot by the camera to obtain corresponding compressed video data; packaging the compressed video data to obtain a corresponding coded video stream; acquiring direction information corresponding to the video data, and adding the direction information into the coded video stream; and packaging the coded video stream added with the direction information to obtain the coded video stream corresponding to the direction information.

The step of adding direction information to the encoded video stream may comprise: and compressing and packaging the video image frame to obtain a coded video stream. And then adding the direction information into the additional information of the coded video stream to complete the addition of the direction information. An exemplary compression algorithm may be shown in table 1, among others.

TABLE 1

The h.264 standard is a highly compressed digital Video codec standard proposed by Joint Video Team (Joint Video Team, JVT) jointly composed of a Telecommunication Union International Telecommunication Standardization Sector (Telecommunication Standardization Sector of the International Telecommunication Standardization Union, ITU-TVCEG) and a Moving Picture Experts Group (MPEG). The H.264 standard may also be referred to as H.264/AVC (advanced Video coding), or AVC/H.264, or H.264/MPEG-4AVC, or MPEG-4/H.264AVC.

In terms of content, the H264 standard mainly includes Access Unit identifiers (Access Unit identifiers), additional enhancement information (SEI), primary Coded Picture (primary Coded Picture), Redundant Coded Picture (Redundant Coded Picture), Instantaneous Decoding Refresh (IDR), Hypothetical Reference Decoder (HRD), Hypothetical Stream Scheduler (HSS), and so on. From the system architecture level, h.264 can be divided into two levels at the system framework level: video Coding Layer-VCL and Network Abstraction Layer-NAL. The VCL is responsible for representing the content of the valid video data and the NAL is responsible for formatting the data and providing header information to ensure that the data is suitable for transmission on various channels and storage media.

The h.265 standard is a new video coding standard established by ITU-TVCEG following h.264. The H.265 standard may also be referred to as the H.265-HEVC (high Efficiency Video coding), or the HEVC/H.265 standard. The h.265 standard surrounds the existing video coding standard h.264, retaining some of the original techniques, while some related techniques are improved.

The encoding architecture of h.265 is substantially similar to that of h.264, and the h.265 standard includes: in the h.265 coding scheme, the whole is divided into three basic units, namely, Coding Unit (CU), Prediction Unit (PU), and Transform Unit (TU). The h.265 standard provides more different tools to reduce the code rate than the h.264 standard, and the size of each Macroblock (MB) in h.264 is 16 × 16 pixels, which is fixed, in terms of the coding unit, while the coding unit of h.265 can be selected from the smallest 8 × 8 to the largest 64 × 64.

The direction information of the embodiment of the present application can be added to the additional information of the encoded video stream, for example, the additional information can be the additional enhancement information in the h.264 standard and the h.265 standard. The encoded video stream may be identified to determine whether the direction information already exists in the encoded video stream, and if not, the direction information is added to the encoded video stream. Taking the h.264 standard as an example, the encoded video stream may be identified, whether additional enhancement information already exists in the NAL of the encoded video stream is determined, and if not, the additional enhancement information including the direction information is inserted into the NAL of the encoded video stream; if so, no insert operation is performed.

In an alternative example, the step of adding the direction information to the encoded video stream comprises: and filtering the direction information, and adding the filtered direction information into the additional information corresponding to the coded video stream. The direction sensor may collect a plurality of directional information and analyze the plurality of directional information for filtering, for example, deleting higher and lower directional information from the plurality of directional information to obtain more accurate directional information, and adding the more accurate directional information to the additional information in the encoded video stream. In another example, the collected multiple direction information may be averaged to obtain the direction information, and added to the additional information of the encoded video stream, thereby improving the accuracy of the direction information.

After obtaining the encoded video stream with the added direction information, the image capturing apparatus may transmit the encoded video stream with the added direction information in step 106, so as to determine a shooting angle at which the camera shoots a video. Specifically, the camera may send the encoded video stream with the added direction information to the streaming media server, and subsequently, the streaming media server may send the encoded video stream with the added direction information to the application processing device for various required processing according to the requirement.

The transmitted data stream includes video code stream data, a control command, and the like, where the transmission of the video code stream may be performed according to a preset code stream transmission protocol, and the code stream transmission protocol may include a protocol shown in table 2.

TABLE 2

Among them, RTP provides an end-to-end transmission service with real-time characteristics for data, and solves parameters such as TCP bandwidth, timestamp, framing, etc., such as interactive video and audio or analog data under multicast or unicast network services. The RTP standard defines two subprotocols: a data transmission protocol and a control protocol. The data transmission protocol is used for transmitting data in real time, and the protocol provides information including: timestamp, sequence number, and payload format. According to the time stamp, data can be synchronized, packet loss and rearrangement sequence monitoring can be performed according to the sequence number, and corresponding format decoding can be performed on the data according to the load format. And a control protocol for quality of service feedback and synchronization of the media streams. The control protocol occupies a small bandwidth.

In order to combine one or more audio streams, video streams or other basic data streams into a single or multiple data streams in the data transmission process, so as to adapt to storage and transmission, the data streams need to be packaged and encoded again, and various time stamps, system control and other information need to be inserted into the code streams and then sent to a channel coding and modulator. This allows two data streams to be formed: transport stream and program stream, respectively, for different applications.

The control command may be understood as a control command for controlling an encoding format, a transmission rate, and a transmission port in video transmission, and the control command transmission may be transmitted according to a signaling transmission protocol, which may include a protocol shown in table 3.

TABLE 3

Among them, the real-time streaming Protocol defines how one-to-many applications efficiently transmit multimedia data over an Internet Protocol (IP) network. SIP is a text-based application-layer control protocol for creating, modifying, and releasing sessions for one or more participants. SIP is an IP voice session control protocol originated from the Internet, has the characteristics of flexibility, easy realization, convenient expansion and the like, solves the networking problem of equipment, and supports the mixed condition of the equipment in an internal network and an external network.

The GB/T28181 standard specifies the interconnection structure and communication protocol structure of information transmission, exchange and control, the basic requirements and safety requirements of transmission, exchange and control, and the technical requirements of control, transmission flow, protocol interface and the like in the urban monitoring alarm networking system.
