The traffic police terminal sends an http traffic data calling request to the data server based on an http protocol, and when the request is sent, a sender can be an internal person of a public security system and used for calling traffic data of pedestrians or vehicles at a monitoring place so that the recognition equipment can judge and process illegal behaviors, and can also be a developer of traffic data calling with access rights and used for calling real-time traffic data of the front-end camera and debugging calling parameters and calling related equipment according to calling response. The http traffic data call request can be sent through a video monitoring platform which is independently developed, and can also be directly sent in a web browser to be received by a data server. The request under the http protocol is a unidirectional channel request from the traffic police terminal to the data server.
The http traffic data call request carries a terminal identifier, an identification device identifier, a target display device identifier and a target camera identifier, wherein the terminal identifier comprises an IP address and a port of a traffic police terminal, the target camera identifier comprises an ID of a target camera, the identification device identifier comprises an IP address and a port of identification equipment, and the target display device identifier comprises an IP address and a port of display equipment. Before a request is sent, the traffic police terminal establishes connection with the identification equipment, and obtains the equipment identification of the identification equipment based on an http protocol. In general, the target display device and the traffic police terminal are the same device, i.e. the traffic police terminal initiating the request is also used as the target display device for displaying the illegal data. The target display device and the traffic police terminal can also be different devices, namely the traffic police terminal initiating the request and the target display device displaying the illegal data are different devices registered in the intelligent traffic system. In addition, the target display device can be multiple, and the multiple target display devices can comprise a traffic police terminal and other display devices, or can be all other display devices.
After receiving a triggering instruction for calling traffic data, the traffic police terminal displays a calling selection page comprising a display device selection control and a front-end camera selection control, and then performs corresponding selection operation on the calling selection page to determine which camera in a monitoring place is required to call the traffic data shot by and which display device is used for displaying illegal data corresponding to the traffic data.

As shown in fig. 4, the framework from sending traffic data call requests to receiving traffic data call responses is divided into several modules, and the data server includes http-side processing logic 22, message synchronizer 23, and sip-side processing logic 24. The traffic police terminal firstly sends an http traffic data calling request 21 sent based on an http protocol to an http side processing logic 22 for processing, and then the http side processing logic 22 sends the http traffic data calling request to a message synchronizer 23; the message synchronizer 23 converts the http traffic data call request into a sip traffic data call request, generates an http state identifier for the http traffic data call request, generates a sip state identifier for the sip traffic data call request, synchronizes the identification contents of the http state identifier and the sip state identifier, and then sends the sip traffic data call request to the sip side processing logic 24 for processing; after the processing of the sip side processing logic 24 is completed, a sip session is established between the processing logic and the target camera 25, a sip traffic data calling request is sent to the target camera 25, and a sip traffic data calling response returned by the target camera 25 to the processing logic 24 of the sip side is received; the sip side processing logic 24 sends the sip traffic data call response to the message synchronizer 23, the message synchronizer 23 synchronously updates the http state identifier and the identifier content of the sip state identifier according to the content of the sip traffic data call response, and generates an http traffic data call response and sends the http traffic data call response to the http side processing logic 22 when the identifier content of the http state identifier is that the traffic data call request is completed; the http side processing logic 22 returns an http traffic data call response 26 to the traffic police terminal, and the traffic police terminal determines the processing state of the traffic data call request according to the http traffic data call response 26.
As shown in fig. 5 and 6, the http side processing logic 22 includes an http service module 221, a request parser 222, a validity judgment 223, an http message manager 224, and an http timer status notification queue 225, and the sip side processing logic 24 includes a sip call management 241, a sip message manager 242, a user agent client 243, a user agent server 244, and a front-end camera sip proxy 245, and the illegal data identification method of the present application is specifically described below with reference to fig. 4 to 6.
The traffic police terminal sends an http traffic data call request 21 to the http side processing logic 22, wherein the http traffic data call request 21 carries a terminal identifier, an identification device identifier, a target display device identifier and a target camera identifier. The terminal identification comprises an IP address and a port of a traffic police terminal, the data server determines which terminal the traffic data call response is transmitted to according to the terminal identification, the target display equipment identification comprises the IP address and the port of the target display equipment, the data server determines which terminal the illegal data is returned to according to the target display equipment identification, the target camera identification comprises the ID of the target camera, the data server determines that the target camera is positioned at the xx road xx intersection according to the target camera identification, so as to send an http traffic data call request 21 to the target camera, the identification equipment identification comprises the IP address and the port of the identification equipment, the data server determines which identification equipment the traffic data transmitted by the subsequent target camera is forwarded to according to the identification equipment identification, and the identification equipment identifies the traffic illegal behavior type, the traffic illegal behavior time, the traffic illegal vehicle or pedestrian information and other data according to the traffic behavior of vehicles or pedestrians in the traffic data and returns the traffic data to the target display equipment for further processing.
In the http side processing logic 22, the http traffic data call request 21 is received by the http service module 221, the http service module 221 comprises an http gateway, and then the http traffic data call request 21 is forwarded to the request parser 222. After the request parser 222 parses each command parameter in the http traffic data call request 21, the http traffic data call request 21 is put into the http message manager 224. The http message manager 224 continually handles the internal message buffering while sending a new incoming http traffic data call request 21 to the message synchronizer 23.
In one embodiment, before the step of placing the http traffic data call request 21 into the http message manager 224, the validity judgment 223 is further performed on the parsed http traffic data call request 21, which specifically includes: based on the effective parameter set of the traffic data call request, carrying out logic judgment on the http traffic data call request 21; if the http traffic data call request 21 is legal, the http traffic data call request 21 is cached to the http message manager 224, and if the http traffic data call request 21 is illegal, a termination request result is directly returned to the traffic police terminal, and the termination request result is expressed as an http traffic data call response 26 at the traffic police terminal. When the traffic police terminal sends out the http traffic data call request 21, the http traffic data call request 21 is usually sent out in the form of inputting a website on a web browser or a platform, parameters such as a terminal identifier, a target camera identifier, a call command and the like are included in the http traffic data call request 21, if the input of each identifier or call command is wrong, the subsequent processing logic is affected, therefore, after analysis, the http traffic data call request 21 is firstly logically judged based on the traffic data call request effective parameter set, the traffic data call request effective parameter set comprises the type of the effective parameter, specific parameter values, the arrangement sequence of each parameter and the like, if the traffic data call request effective parameter set is legal, the next step is entered, the http traffic data call request 21 is cached in the http message manager 224, if the http traffic data call request 21 is illegal, a termination request result is directly returned to the traffic police terminal, and specific error types can be further displayed, if the invalid parameters are input or the corresponding target camera and the like cannot be found, so that the traffic police terminal can conveniently adjust the http traffic data call request 21 and re-input.
In one embodiment, after the step of caching the http traffic data call request 21 to the http message manager 224, further comprising: judging whether the http traffic data calling request 21 is the same as the http traffic data calling request which enters in the preset time period; if the content is the same, the http traffic data call request 21 is removed from the http message manager 224, and if the content is different, the http traffic data call request 21 is sent to the message synchronizer 23. After the traffic police terminal sends the http traffic data call request 21, if no traffic data call response is received within the expected time, one or more refreshing operations are usually performed, each refreshing operation will send out one traffic data call request 21 again, and the content of each sent traffic data call request 21 is the same, if the data server processes each request, resource waste will be caused, so after the http traffic data call request 21 is cached in the http message manager 224, the http message manager 224 will number the incoming requests in time sequence, such as number 1, number 2, number 3, etc., and check and re-determine each time a new http traffic data call request 21 is entered.
Assuming that the new incoming http traffic data call request 21 is numbered n, the http message manager 224 first determines whether there is an n-1 request to enter within a preset period of time from the n-th request entry time, where the preset period of time may be set according to the sending behavior of most request senders, for example, 2 seconds may be used as the preset period of time if most request senders start to reinitiate the request after receiving no response within 2 seconds after sending the request. If no n-1 request is detected to enter within the previous preset time period, a new entering http traffic data call request can be directly sent to the message synchronizer 23. If it is detected that the n-1 th request enters in the preset time period, the n-1 th request and the n-1 th request are subjected to content check and duplication judgment, when the content is the same, the n-1 th request is indicated to be a repeated request, the newly-entered http traffic data calling request is removed from the http message manager 224, the n-1 th request is continuously processed, when the content is different, the n-1 th request is indicated to be a new request, the newly-entered http traffic data calling request is sent to the message synchronizer 23, and after the n-1 th request is processed, the n-1 th request is continuously processed.
After receiving the http traffic data call request 21, the message synchronizer 23 generates a sip traffic data call request corresponding to the http traffic data call request according to the target camera identification. The front-end cameras registered in the data server are all located in the cluster information, each front-end camera is provided with a unique identification, a target camera is determined from the front-end camera cluster information according to the target camera identification, an access address of the target camera is obtained, and a request head in a sip traffic data call request can be generated according to the access address. Then, each call command in the http traffic data call request 21 is converted into a call command under the sip protocol, and then the call command is generated into a message body in the sip traffic data call request, and the request header and the message body are combined to generate a corresponding sip traffic data call request.
The message synchronizer 23 generates an http state identifier for the http traffic data call request 21, generates a sip state identifier for the sip traffic data call request, and synchronizes the http state identifier and the identification content of the sip state identifier in real time, wherein the identification content comprises a traffic data call request completion state. In the message synchronizer 23, the http state identifier and the sip state identifier have the same identifier content at any time, and the synchronization operation is realized through a corresponding synchronization program.
For the http traffic data call request 21 newly entering the message synchronizer 23, after the steps of format conversion and identification synchronization are completed, the sip traffic data call request is sent to the sip side processing logic 24, and then the sip side processing logic 24 sends the sip traffic data call request to the target camera corresponding to the target camera identification based on the sip protocol. After sending, the message synchronizer 23 will complete detection on the traffic data call request, if the sip side processing logic 24 has returned a sip traffic data call response, the message synchronizer 23 will generate a corresponding http traffic data call response and put it into the http timer status notification queue 225, the http timer status notification queue 225 notifies the http message manager 224 according to the sequence of entering the response, and the http message manager 224 returns an http traffic data call response 26 to the traffic police terminal, so that the traffic police terminal can obtain the processing result of the traffic data call request.
In the sip-side processing logic 24, the specific steps of the process include: caching the sip traffic data call request into a sip message manager 242 and establishing a session with a front-end camera sip proxy 245 based on a sip protocol; determining a target camera 25 from the front-end camera sip proxy 245 according to the target camera identification; the sip traffic data call request is sent to the target camera 25 based on the sip protocol.
The sip traffic data call request is first sent to the sip call manager 241, and the sip call manager 241 generates a unique identifier for the sip traffic data call request and then caches the unique identifier in the sip message manager 242. The user agent client 243 then checks from the sip message manager 242 whether a new traffic data call request arrives or an update of the traffic data call request status, and sends a different request to the front-end camera sip agent 245 according to the check result. When it is checked that a new sip traffic data call request arrives in the sip message manager 242, the user agent client 243 calls its own proxy mode, establishes a session with the front-end camera sip proxy 245 based on the sip protocol, sends an Invite request, and after the front-end camera sip proxy 245 receives the Invite request, determines the target camera 25 from the front-end camera sip proxy 245 according to the target camera identifier, and then the front-end camera sip proxy 245 sends the sip traffic data call request to the target camera 25. When it is detected that there is a status update of the traffic data call request in the sip message manager 242, if the request is terminated, a corresponding processing request is sent to the front-end camera sip proxy 245 according to the updated status.
Next, the sip-side processing logic 24 receives the sip traffic data call response returned by the target camera 25 based on the sip protocol, and synchronously updates the identification content of the sip state identification and the http state identification according to the content of the sip traffic data call response.
In one embodiment, the steps specifically include: receiving processing signaling returned by the target camera 25 to the sip message manager 242 based on the sip protocol; updating the identification content of the sip state identification corresponding to the sip traffic data call request in the sip message manager 242 according to the processing signaling; when the identification content of the sip state identification is detected to be that the traffic data calling request is completed, returning a sip traffic data calling response to the message synchronizer 23; and synchronously updating the identification contents of the sip state identification and the http state identification in the message synchronizer 23 according to the contents of the sip traffic data call response.
The processing signaling returned by the target camera 25 after processing the sip traffic data call request is received by the user agent server 244, and the user agent server 244 updates the identification content of the sip status identification corresponding to the sip traffic data call request in the sip message manager 242 according to the processing signaling. Specifically, when the processing signaling is 200OK, which indicates that the traffic data call request is completed, the user agent server 244 matches the sip traffic data call request in the sip message manager 242 and updates the identification content of the corresponding sip status identifier to the traffic data call request.
When the identification content of the sip state identification is detected to be the traffic data call request is completed, a sip traffic data call response is generated and returned to the message synchronizer 23, and then the identification content of the sip state identification and the identification content of the http state identification in the message synchronizer 23 are synchronously updated according to the content of the sip traffic data call response, and then the identification content of the sip state identification and the identification content of the http state identification are updated to be the traffic data call request.
In one embodiment, the steps after returning the sip traffic data call response to the message synchronizer 23 include: the sip traffic data call request is removed from the sip message manager 242. At this point the traffic data call request has been processed and a corresponding traffic data call response is generated, so that it is removed from the sip message manager 242 and the buffer space of the sip message manager 242 can be freed up to facilitate the sip message manager 242 to process further request messages. In addition, after removal, the data server can store relevant logs of the sip traffic data call responses, classify a plurality of traffic data call responses within a certain period of time in the logs, for example, classify according to the traffic data call request completion time, analyze the condition of longer processing time, find reasons, facilitate the developers to perform BUG positioning and program debugging, and subsequently maintain and upgrade the system.
When the identification content of the http state identification is that the traffic data call request is completed, the message synchronizer 23 generates an http traffic data call response corresponding to the http state identification, and returns an http traffic data call response 26 to the traffic police terminal based on the http protocol according to the terminal identification. The message synchronizer 23 determines which port of which client the traffic data call response should be sent to according to the terminal identification, and then returns the http traffic data call response 26, and the traffic police terminal determines the processing result of the traffic data call request according to the content of the http traffic data call response 26.
In one embodiment, the steps following the return of the http traffic data call response 26 to the traffic police terminal include: the http traffic data call request and the sip traffic data call request are removed from the message synchronizer 23. After removal, the internal space of the message synchronizer 23 is also released to facilitate the message synchronizer 23 to process further request messages.
After the traffic police terminal acquires the http traffic data call response 26, the target camera 25 packages and transmits the photographed traffic data to the data server, and then the data server transmits the packaged traffic data to the identification device according to the identification device IP address and the port in the identification device identifier. After receiving traffic data, the identification equipment unpacks the traffic data, pre-processes the unpacked traffic data, such as removing some non-video data, interference data and the like, then inputs the traffic data into a pre-trained neural network model, and the neural network model identifies illegal data.
The neural network model firstly detects and tracks pedestrian targets and vehicle targets in each frame of image of the video, and determines the behavior track of the pedestrian targets and the vehicle targets. In order to reduce the influence of false detection and omission, the system judges that a new target enters only when continuous M frames of the target are detected, and considers that the target has disappeared only when continuous N frames of the target are not detected, wherein M and N are positive integers, and can be set to different values according to the type of the target, the running speed and other parameters. Specifically, in the process of tracking the targets, the historical position of each target is recorded, the initial motion track of each target is formed, and the initial motion track of each target is subjected to smooth filtering by adopting a kalman filter, so that the target behavior track is obtained.
Then, the neural network model identifies the detected vehicle target, so that the attributes of the brand, the vehicle type, the license plate number, the vehicle color and the like of the detected vehicle target can be obtained, and the attributes of the sex, the height, the clothes, the hair style and the like of the detected pedestrian target can be obtained. After detection, the attribute of the detected target can be stored in the identification device or the data server for subsequent search query of the detected illegal target, and basis is provided for punishment.
Then, the neural network model identifies traffic marks of the road where the target is located, such as traffic signal lamps, traffic marking lines, speed limit signs and the like, and then judges whether traffic illegal behaviors exist in the target according to the detected information such as the position where the target is located, the target behavior track, the target attribute, the traffic marks of the road where the target is located and the like.
For example, when the traffic signal lamp is recognized to be in a red light state and the traffic marking of the current road comprises a stop line, whether the position of the target exceeds the stop line is judged within a range of 15 meters before and after the stop line, and if so, the illegal action of running the red light exists. For another example, when the traffic markings of the current road are identified to include road type markings, such as pedestrian lanes, motor lanes, and non-motor lanes, and the target attribute is identified to be not matched with the type of the current road, illegal action of illegally occupying the road exists.
In the embodiment of the application, illegal data identification is performed by using the identification equipment running with the neural network model, and the identification efficiency of the neural network model is gradually increased after the neural network model is trained for a plurality of times. When training the neural network model, the video data shot by the front-end camera is required to be acquired, all the characteristics in the video data are artificially marked, then the video data are input into the neural network model as training samples for training, and when traffic data to be identified are input subsequently, the trained neural network model can have corresponding identification capability.
In the training sample, the pedestrian target and the vehicle target are manually marked, and when traffic data is input subsequently, the trained neural network model can have the capability of identifying the pedestrian target and the vehicle target. In the training sample, the attribute of the pedestrian target and the attribute of the vehicle target are marked by people, so that the trained neural network model can have the capability of identifying the attribute of the pedestrian target and the attribute of the vehicle target. In the training sample, different labels are manually carried out on the pixels where the non-traffic marks are located and the pixels where the traffic marks are located, and corresponding traffic mark types are marked at the same time, so that the trained neural network model can have the capability of identifying the traffic marks and the corresponding categories thereof. Through the three training, the neural network model can identify the information such as the position where the target is located, the target behavior track, the target attribute, the traffic identification of the road where the target is located and the like according to the input traffic data, so that understanding of the road traffic video is completed, and further, illegal behaviors are identified. In order to make the recognition effect of the neural network model better, training needs to be performed for a sufficient number of times so that the recognition accuracy is not lower than a preset value.

In addition, if there are multiple illegal actions in the traffic data, multiple rows of characters are displayed in the illegal data display area 500, each row of characters correspondingly describes one illegal action, and videos corresponding to the illegal actions described by the row of characters can be played one by clicking each row of characters in turn. When traffic data shot by other front-end cameras is wanted to be called after the watching is completed, the traffic data calling control 100 can be clicked again to generate a next data calling request. When the target display device and the traffic police terminal are different devices, the link address for displaying the illegal data can be sent to the target display device, and after the target display device clicks the link address, the illegal data display area 500 is displayed in the clicked page, so that illegal data can be displayed on other devices except the traffic police terminal.
