Referring to fig. 2, fig. 2 is a schematic flowchart of a method for identifying illegal data according to an embodiment of the present application, where the method includes:
s201: receiving an http traffic data calling request sent by a traffic police terminal based on an http protocol; the http traffic data calling request comprises the steps that after a traffic police terminal receives a triggering instruction for calling traffic data, a calling selection page comprising a display equipment selection control and a front-end camera selection control is displayed, target display equipment is determined according to selection operation aiming at the display equipment selection control, a target camera is determined according to selection operation aiming at the front-end camera selection control, and the http traffic data calling request conforming to an http protocol is generated according to a terminal identification of the traffic police terminal, an identification equipment identification of the identification equipment, a target camera identification of the target camera and a target display equipment identification of the target display equipment.
The traffic police terminal sends an http traffic data calling request to the data server based on an http protocol, when the request is sent, a sender can be an internal person of a public security system and is used for calling traffic data of pedestrians or vehicles in a monitoring place so as to enable identification equipment to judge and process illegal behaviors, and the sender can also be a developer with access authority and used for calling real-time traffic data of a front-end camera and debugging calling parameters and calling related equipment according to calling responses. The http traffic data calling request can be sent through a video monitoring platform which is developed independently, or can be directly sent through a web browser and received by a data server. The request under the http protocol is a one-way channel request from the traffic police terminal to the data server.
The http traffic data calling request carries a terminal identification, an identification equipment identification, a target display equipment identification and a target camera identification, wherein the terminal identification comprises an IP address and a port of a traffic police terminal, the target camera identification comprises an ID of a target camera, the identification equipment identification comprises the IP address and the port of the identification equipment, and the target display equipment identification comprises the IP address and the port of the display equipment. Before sending the request, the traffic police terminal establishes connection with the identification device, and obtains the device identifier of the identification device based on the http protocol. In general, the target display device and the traffic police terminal are the same device, that is, the traffic police terminal initiating the request also serves as the target display device displaying the illegal data. The target display device and the traffic police terminal can also be different devices, namely the traffic police terminal which initiates the request and the target display device which displays the illegal data are different devices which are registered in the intelligent traffic system. In addition, there may be a plurality of target display devices, and the plurality of target display devices may include a traffic police terminal and other display devices, or may all be other display devices.
After receiving a triggering instruction for calling traffic data, the traffic police terminal displays a calling selection page comprising a display equipment 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 be called to shoot the traffic data and which display equipment displays illegal data corresponding to the traffic data. When the display device selection control is triggered, a list of all registered display devices is generated, then one or some display devices can be selected as target display devices, and the display device list can set the traffic police terminal initiating the request or the display device selected by the last request as the default target display device. When the front-end camera selection control is triggered, directories of all registered front-end cameras are generated, one of the directories can be selected as a target camera, and the front-end camera selected by the previous request can be set as a default target camera in the front-end camera directory.
And after the corresponding selection operation is carried out on the calling selection page, generating an http traffic data calling request according with an http protocol according to the terminal identifier of the traffic police terminal, the target display device identifier of the target display device and the target camera identifier of the target camera.

And then, converting each calling command in the http traffic data calling request into a calling command under an sip protocol, generating the calling command into a message body in the sip traffic data calling request, and combining a request header and the message body to generate a corresponding sip traffic data calling request.
After the sip traffic data calling request corresponding to the http traffic data calling request is generated, corresponding http state identification and sip state identification are respectively generated for the http traffic data calling request and the sip traffic data calling request, and identification contents of the two state identifications comprise the starting time of the traffic data calling request and the completion state of the traffic data calling request. And synchronizing the identification contents of the http state identification and the sip state identification, namely, when the identification content of one of the http state identification and the sip state identification changes at any moment, the identification content of the other one of the http state identification and the sip state identification changes in the same way. When the traffic data call request is not processed, the traffic data call request completion state in the identification content always shows that the traffic data call request is not completed, and if a traffic data call response is received, the traffic data call request completion state in the identification content shows that the traffic data call request is completed.
S203: sending an sip traffic data calling request to a target camera corresponding to the target camera identification based on the sip protocol, receiving an sip traffic data calling response returned by the target camera based on the sip protocol, and synchronously updating the identification contents of the sip state identification and the http state identification according to the content of the sip traffic data calling response.
After the sip traffic data calling request is obtained, according to the identification of the target camera, a sip session is established between the data server and the target camera, the sip traffic data calling request is sent to the corresponding target camera, and the target camera processes the request after receiving the sip traffic data calling request.
After the target camera processes the sip traffic data calling request, sending a processing signaling to the data server through an sip session established between the target camera and the data server, generating an sip traffic data calling response according to the processing signaling, and then synchronously updating the identification contents of the sip state identification and the http state identification according to the content of the sip traffic data calling response.

In the protocol conversion process, the identification contents of the sip state identification and the http state identification are synchronized, so that the generated sip traffic data call response can be converted into the http traffic data call response in time, and the response returning speed is improved.
As shown in fig. 3, a platform interface of the traffic police terminal is provided with a call traffic data control 100, and when the call traffic data control 100 is clicked when the traffic data shot at a certain intersection at a certain time is to be called, the traffic police terminal receives a trigger instruction for calling the traffic data, and displays a call selection page including a display device selection control 200 and a front-end camera selection control 300. The calling traffic data control 100 and the other two controls can be arranged on different pages, that is, the calling selection page can be a page generated by clicking the calling traffic data control 100 on another page of the traffic police terminal; the calling traffic data control 100 and the other two controls can be arranged on the same page, when the calling traffic data control 100 is not clicked, the other two controls are not displayed, and after the calling traffic data control 100 is clicked, the page serves as a calling selection page to display the display device selection control 200 and the front-end camera selection control 300.

In performing the selection operation, one or more display devices may be selected from the display device directory 201 as target display devices, wherein the traffic police terminal initiating the request or the display device selected last time may be set as a default target display device. When there are many display devices in the display device directory 201, a search or screening function may be set, and the search range is narrowed according to information such as keywords, so that a target display device to be selected can be quickly searched.
Similarly, after the front-end camera selection control 300 is clicked on the calling selection page, the calling selection page generates a front-end camera directory 301 according to the trigger operation for the front-end camera selection control 300, all front-end cameras registered in the intelligent traffic system can be displayed in the front-end camera directory 301, and then the corresponding selection operation is performed on the front-end camera directory 301 to determine which camera in the monitoring place to view the traffic data. In performing the selection operation, one of the front-end cameras from the front-end camera list 301 may be selected as a target camera, wherein the front-end camera that was last requested to be selected may be set as a default target camera. When there are many front-end cameras included in the front-end camera directory 301, a search or screening function may be set, and the search range is narrowed down according to information such as keywords, so that a target camera desired to be selected is quickly searched.

As shown in fig. 5 and fig. 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 an sip call manager 241, an sip message manager 242, a user agent client 243, a user agent server 244, and a front-end camera sip agent 245, and the method for recognizing illegal data according to the present application is specifically described below with reference to fig. 4 to fig. 6.
The traffic police terminal sends an http traffic data call request 21 to the http side processing logic 22, and 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 sent to after receiving the traffic data call response according to the terminal identification, the target display equipment identification comprises the IP address and the port of target display equipment, the data server determines which terminal the illegal data should be sent back to according to the target display equipment identification, the target camera identification comprises an ID of a target camera, the data server determines that the target camera is specifically positioned at a xx road section xx intersection in an xx area 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 identification equipment, the data server determines which identification equipment the traffic data sent by the subsequent target camera should be forwarded to according to the identification equipment identification, and the identification equipment determines the traffic behavior of vehicles or pedestrians at the intersection in the traffic data, and identifying data such as traffic violation behaviors, traffic violation behavior time, information of traffic violation vehicles or pedestrians and the like, and returning the data to the target display equipment for further processing.
In the http side processing logic 22, the http traffic data invoking request 21 is received by the http service module 221, the http service module 221 includes an http gateway, and then the http traffic data invoking request 21 is transferred to the request parser 222. The request parser 222 parses each command parameter in the http traffic data invoking request 21, and then puts the http traffic data invoking request 21 into the http message manager 224. The http message manager 224 continuously processes the internal message cache while sending the newly incoming http traffic data call request 21 to the message synchronizer 23.
In an embodiment, before the step of placing the http traffic data invocation request 21 into the http message manager 224, the validity judgment 223 is further performed on the parsed http traffic data invocation request 21, which specifically includes: carrying out logic judgment on the http traffic data calling request 21 based on the traffic data calling request effective parameter set; and if the http traffic data call request 21 is legal, caching the http traffic data call request 21 into the http message manager 224, and if the http traffic data call request 21 is illegal, directly returning a termination request result to the traffic police terminal, wherein the termination request result is represented 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 sent out in a form of inputting a website on a web browser or a platform, the http traffic data call request 21 comprises parameters such as a terminal identifier, a target camera identifier and a call command, if the input of each identifier or call command is wrong, subsequent processing logic is affected, therefore, after analysis, firstly, a logic judgment is made on the http traffic data call request 21 based on a traffic data call request effective parameter set, the traffic data call request effective parameter set comprises types of effective parameters, specific parameter values, an arrangement sequence of each parameter and the like, if the valid parameter set is legal, the next step is carried out, the http traffic data call request 21 is cached in the http message manager 224, if the valid parameter set is illegal, a termination request result is directly returned to the traffic police terminal, and a specific error type can be further displayed, if the input is an invalid parameter or a corresponding target camera cannot be found, and the like, so that the http traffic data call request 21 can be adjusted and input again by the traffic police terminal.
In one embodiment, after the step of caching the http traffic data invocation request 21 to the http message manager 224, the method further comprises: judging whether the http traffic data calling request 21 has the same content as the http traffic data calling request entering in the previous preset time period or not; if the content is the same, the http traffic data invocation request 21 is removed from the http message manager 224, and if the content is different, the http traffic data invocation 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 an expected time, one or more refresh operations are usually performed, each refresh operation re-sends one traffic data call request 21, the content of each sent traffic data call request 21 is the same, and if the data server processes each request, resource waste is caused, so after the http traffic data call request 21 is cached in the http message manager 224, the http message manager 224 numbers the incoming requests in time sequence, such as No. 1, No. 2, No. 3, and the like, and each time a new http traffic data call request 21 is entered, the incoming requests are re-checked and judged.
Assuming that the number of the newly entered http traffic data invocation request 21 is n, the http message manager 224 first determines whether an n-1 th request enters within a preset time period from the time of the n-th request entering, where the preset time period may be set according to the sending behavior of the majority of request senders, for example, if the majority of request senders do not receive a response within 2 seconds after sending the request, the request senders may start to initiate a request again, and then 2 seconds may be used as the preset time period. If it is detected that no request n-1 is entered within the previous preset time period, the newly entered http traffic data call request may be directly sent to the message synchronizer 23. If an n-1 request is detected to enter in the previous preset time period, content duplication judgment is carried out on the n-1 request and the n request, when the contents are the same, the n request is a repeated request, the newly entered http traffic data calling request is removed from the http message manager 224, the n-1 request is continuously processed, when the contents are different, the n request is a new request, the newly entered http traffic data calling request is sent to the message synchronizer 23, and after the n-1 request is processed, the n request is continuously processed.
After receiving the http traffic data call request 21, the message synchronizer 23 generates an sip traffic data call request corresponding to the http traffic data call request according to the identification of the target camera. The data server stores cluster information of front-end cameras, the front-end cameras registered in the data server are all located in the cluster information, each front-end camera has a unique identifier, a target camera is determined from the cluster information of the front-end cameras according to the identifier of the target camera, an access address of the target camera is obtained, and a request head in a sip traffic data calling 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 a 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 an 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 includes a traffic data call request completion state. In the message synchronizer 23, the identification contents of the http state identification and the sip state identification are the same at any moment, and the synchronization operation is realized by 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 the sending, the inside of the message synchronizer 23 can complete the detection on the traffic data call request, if the sip side processing logic 24 has returned the sip traffic data call response, the message synchronizer 23 can generate a corresponding http traffic data call response, and place the http traffic data call response into the http timer state notification queue 225, the http timer state notification queue 225 notifies the http message manager 224 according to the sequence of the response entering, and the http traffic data call response 26 is returned to the traffic police terminal by the http message manager 224, 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 processing include: caching the sip traffic data call request into the sip message manager 242, and establishing a session with the front-end camera sip agent 245 based on the sip protocol; determining a target camera 25 from the front-end camera sip agent 245 according to the target camera identification; and sending the sip traffic data calling request to the target camera 25 based on the sip protocol.
The sip traffic data invoking request is first sent to the sip invoking management 241, and the sip invoking management 241 generates a unique identifier for the sip traffic data invoking request and then caches the unique identifier into the sip message manager 242. Then, the user agent client 243 checks from the sip message manager 242 whether a new traffic data call request arrives or whether the traffic data call request status is updated, and sends a different request to the front-end camera sip agent 245 according to the check result. When a new sip traffic data call request arrives at 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, and sends an Invite request, after the front-end camera sip proxy 245 receives the Invite request, the front-end camera sip proxy 245 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 checked that the state of the traffic data call request is updated 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 state.
Then, 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 contents 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 a 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 calling request in the sip message manager 242 according to the processing signaling; when detecting that the identification content of the sip state identification is that the traffic data calling request is completed, returning a sip traffic data calling response to the message synchronizer 23; and according to the content of the sip traffic data call response, synchronously updating the identification content of the sip state identification and the http state identification in the message synchronizer 23.
The processing signaling returned by the target camera 25 after processing the sip traffic data invocation request is received by the user agent 244, and the user agent 244 updates the identification content of the sip state identification corresponding to the sip traffic data invocation request in the sip message manager 242 according to the processing signaling. Specifically, when the processing signaling is 200OK, indicating that the traffic data invocation request is completed, the user agent 244 matches the sip traffic data invocation request in the sip message manager 242, and updates the identification content of the corresponding sip status identifier to the completion of the traffic data invocation request.
When detecting that the identification content of the sip state identification is that the traffic data call request is completed, generating and returning a sip traffic data call response to the message synchronizer 23, and then synchronously updating the identification content of the sip state identification and the http state identification in the message synchronizer 23 according to the content of the sip traffic data call response, so that the identification content of the sip state identification and the http state identification is updated to be that the traffic data call request is completed.
In one embodiment, the steps after returning the sip traffic data invocation response to the message synchronizer 23 include: the sip traffic data invocation request is removed from the sip message manager 242. At this point, the traffic data invocation request has been processed and a corresponding traffic data invocation response is generated, so that it is removed from the sip message manager 242, and the cache space of the sip message manager 242 can be released to facilitate the sip message manager 242 to process other request messages. In addition, after the removal, the data server can store the log related to the sip traffic data call response, classify a plurality of traffic data call responses in a certain period of time in the log, for example, classify according to the completion time of the traffic data call request, analyze the condition with long processing time, find the reason, and facilitate the development personnel to perform BUG positioning and program debugging, and subsequently maintain and upgrade the system.
And when the identification content of the http state identification is the traffic data calling request, the message synchronizer 23 generates an http traffic data calling response corresponding to the http state identification, and returns an http traffic data calling 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 identifier, 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 after returning the http traffic data invocation response 26 to the traffic police terminal include: the http traffic data invocation request and the sip traffic data invocation 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 other request messages.
After the traffic police terminal obtains the http traffic data call response 26, the target camera 25 packages the shot traffic data and sends the packaged traffic data to the data server, and then the data server sends 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 the traffic data, the identification device unpacks the traffic data, preprocesses the unpacked traffic data, such as removing some non-video data, interference data and the like, inputs the traffic data into a pre-trained neural network model, and identifies illegal data by the neural network model.
The neural network model firstly detects and tracks the pedestrian target and the vehicle target in each frame of image of the video and determines the behavior track of the pedestrian target and the vehicle target. In order to reduce the influence of false detection and missed detection, the system can judge that a new target enters only when M continuous frames of the target are detected, and can consider that the target disappears only when N continuous frames of the target are not detected, wherein M and N are positive integers and can be set to different values according to parameters such as the type of the target, the driving speed and the like. Specifically, in the target tracking process, the historical position of each target is recorded, an initial motion trajectory of the target is formed, and the initial motion trajectory of the target is subjected to smooth filtering by adopting a kalman filter, so that a target behavior trajectory is obtained.
Then, the neural network model identifies the detected vehicle target to obtain attributes such as brand, vehicle type, license plate number, vehicle color and the like, and identifies the detected pedestrian target to obtain attributes such as gender, height, clothing, hairstyle and the like. After the detection, the attribute of the detected target may be stored in the identification device or the data server, so as to be used for performing a subsequent search query on the detected illegal target, thereby providing a basis for punishment.
Then, the neural network model identifies the traffic signs of the road where the target is located, such as traffic signal lamps, traffic marking lines, speed limit boards and the like, and then judges whether traffic illegal behaviors exist in the target or not according to the detected information of the position where the target is located, the target behavior track, the target attribute, the traffic signs of the road where the target is located and the like.
For example, when it is recognized that the traffic signal lamp is in a red light state and the traffic marking of the current road includes a stop line, it is determined whether the position of the target exceeds the stop line within 15 meters before and after the stop line, and if so, there is illegal behavior of running the red light. For another example, when the traffic markings of the current road include road type markings, such as pedestrian lanes, motor lanes, and non-motor lanes, and the target attribute is not matched with the type of the current road, illegal road occupation behaviors exist.
In the embodiment of the application, illegal data are identified by using the identification equipment operated 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 multiple times. When the neural network model is trained, video data shot by a front-end camera needs to be acquired, all features of the video data are artificially labeled, the video data are input into the neural network model as a training sample for training, and the trained neural network model can have corresponding recognition capability when traffic data to be recognized are subsequently input.
In the training sample, the pedestrian target and the vehicle target are artificially labeled, and when traffic data is subsequently input, the trained neural network model can have the capacity of identifying the pedestrian target and the vehicle target. In the training sample, attributes of the pedestrian target and the vehicle target are labeled manually, and the trained neural network model can have the capability of identifying the attributes of the pedestrian target and 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 the corresponding traffic mark types are labeled, so that the trained neural network model can have the capacity of identifying the traffic marks and the corresponding classes thereof. Through the three types of training, the neural network model can identify information such as the position of a target, a target behavior track, target attributes, traffic identification of a road where the target is located and the like according to input traffic data, so that understanding of a road traffic video is completed, and identification of illegal behaviors is achieved. In order to make the recognition effect of the neural network model better, training needs to be performed for enough times so that the recognition accuracy is not lower than a preset value.
After the traffic violation of the target is identified, the identification equipment generates corresponding violation data, the violation data comprises information such as violation time, violation places, violation targets and violation types, and then the violation data is returned to the data server based on the http protocol, and the data server returns the violation data to the target display equipment according to the target display equipment identification. And the traffic police terminal determines whether to punish the illegal target based on relevant legal provisions according to the illegal data.
In this embodiment, taking the target display device and the traffic police terminal as the same device as an example, as shown in fig. 7, after the target display device receives the illegal data, the illegal data is displayed in the illegal data display area 500, the displayed content includes text description and video, for example, the displayed text is "the vehicle with license plate number xxxxxx does not give way to pedestrians at xx crossing at xx moment", after the text is triggered, the whole video process of the illegal vehicle without giving way to pedestrians can be displayed in the illegal data display area 500, so that the identification and subsequent processing of the traffic illegal data are realized. In addition, if there are multiple illegal activities in the traffic data, multiple lines of characters are displayed in the illegal data display area 500, each line of characters correspondingly describes one illegal activity, and videos corresponding to the illegal activities described by the lines of characters can be played one by sequentially clicking each line of characters. When the traffic data shot by other front-end cameras is required to be called after the watching is finished, the traffic data 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 of illegal data display can be sent to the target display device, and after the target display device clicks the link address, the illegal data display area 500 can be displayed in the opened page, so that illegal data can be displayed on other devices except the traffic police terminal.
According to the illegal data identification method, the http traffic data calling request is sent out on the calling selection page based on the http protocol and is converted into the sip traffic data calling request which can be identified by the front-end camera, then the sip traffic data calling response returned by the front-end camera is converted into the http traffic data calling response and is returned to the traffic police terminal, when the request is initiated on the calling selection page, the corresponding target camera and the target display equipment can be selected only according to the selection operation, the operation is simple, the whole calling process traffic police terminal can be completed only on a web browser or a platform, special SDK software does not need to be called, and therefore safety is guaranteed, the http is a general protocol, the operation is simple, understanding is facilitated, and convenience in data calling is improved. In addition, adopt the neural network model of training to discern illegal data, for artifical recognition, improved recognition efficiency, and the recognition process is independent of outside the data server, when the system needs the upgrading, only need upgrade to identification equipment, and need not carry out whole upgrading to the data server that the data bulk is great, consequently improved upgrading efficiency, also reduced the cost of data maintenance.
