[0049] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0050] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a method for identifying enterprise hazardous chemicals behavior based on multiple data, and the identification method includes:

[0051] Acquire monitoring images of transport vehicles in the supervision area; perform image recognition processing on the monitoring images of transport vehicles in the supervision area to obtain identification information of hazardous chemical vehicles; and obtain positioning information and travel trajectory information of hazardous chemical vehicles based on the identification information of hazardous chemical vehicles; determine the stop area of ​​hazardous chemical vehicles based on the positioning information and travel trajectory information of hazardous chemical vehicles;

[0052] Obtain the location information of the corresponding enterprise entity in the parking area of ​​the hazardous chemical vehicle and the registration information of the corresponding enterprise entity, as well as the transportation registration product information of the hazardous chemical vehicle and the registration status information of the hazardous chemical vehicle; determine the judgment logic according to the registration status information of the hazardous chemical vehicle; if the registration status information of the hazardous chemical vehicle is the registration status, the judgment logic executed is:

[0053] The hazardous chemical behavior status of the corporate entities in the hazardous chemical vehicle's stop area is determined by using the positioning information of the corresponding corporate entities in the hazardous chemical vehicle's stop area, the registration information of the corresponding corporate entities and the transportation registration product information of the hazardous chemical vehicle.

[0054] Preferably, the stopping area of ​​the hazardous chemicals vehicle includes: a sequence of at least one stopping point location; the stopping point location is a data set of the trajectory of the vehicle when the stopping time exceeds the constraint condition; the sequence of stopping point locations is the stopping point locations arranged in time.

[0055] If the registration status information of the hazardous chemicals vehicle is in a non-registration state, the judgment logic executed is: generate and send the registration status information of the hazardous chemicals vehicle as an early warning message. Preferably, the early warning message is sent to the terminal of the regulatory department for prompting. This improves the timeliness of monitoring and the efficiency of supervision.

[0056] Furthermore, the supervision area is larger than the parking area of ​​hazardous chemical vehicles; the supervision area and the parking area of ​​chemical vehicles are selected and set according to the supervision needs; the set area includes the GPS location information of all reference locations. The GPS location information is transmitted to the database in real time through the position sensor on the hazardous chemical vehicle. The driving trajectory of the hazardous chemical vehicle is composed of trajectory points, and the trajectory P = {X1, X2, ..., X n}, trajectory point X i ={T i , a i , b i}, where {a i , b i}, is the spatial coordinate data of GPS location information, representing latitude and longitude, T i is the timestamp data, i = {0, 1, 2, ..., n}, where T0 < T1, ..., < T n The stop position of the hazardous chemical transport vehicle in the stop area is a stop point set (track information) of a trajectory SX = {X s1 , X s2 , ..., X sn}. X SN Represents the Nth stop point; within a specific range, if the time interval between the timestamp data of the same GPS location information is greater than a set value such as 60 seconds, then the point is identified as a stop point; the stop point area is composed of a sequence of stop points and has time continuity. Represents the Nth track. The data in the embodiment includes: the location information and registration information of the corresponding enterprise entity in the stop area of ​​the monitoring area, as well as the transportation registration product information of the hazardous chemical vehicle, the transportation registration product information of the hazardous chemical vehicle; all registered enterprise information in the supervision area, among which the enterprise entity information has been registered in the hazardous chemical vehicle information, where the track information of the hazardous chemical vehicle i is SX i ={X s1 , X s2 , ..., X sn}.

[0057] The data in the embodiment is stored in a database, and the corresponding identification information of the registered hazardous chemical vehicle information such as the license plate and the registration information of the enterprise entity, as well as the transportation registration product information on the hazardous chemical vehicle can be queried through the location information of the enterprise; the transportation registration product information of the hazardous chemical vehicle and the registration status information of the hazardous chemical vehicle can be queried through the license plate. Not in the registered status means: not registered and does not hold a hazardous chemical road transport license. The registered status means: not registered but holds a hazardous chemical road transport license and, registered and holds a hazardous chemical road transport license.

[0058] Specifically, monitoring images of transport vehicles in the supervision area are obtained; image recognition processing is performed on the monitoring images of transport vehicles in the supervision area to obtain identification information of hazardous chemical vehicles such as license plates.

[0059] The image recognition of the transport vehicle monitoring image can be completed by using existing image recognition or by using the following method; preferably, the image recognition processing of the transport vehicle monitoring image in the supervision area to obtain the identification information of the hazardous chemical vehicle includes:

[0060] Obtain the gradient or edge direction histogram of each pixel in the monitoring image of the transport vehicle in the supervision area, and connect these histograms in series to form a feature description of the entire block, and then connect the feature descriptions of each block in the image in series to form a feature description of the entire image as a feature vector used for classification; use the feature vector used for classification with a trained classifier to obtain the identification information of the hazardous chemical vehicle. Furthermore, before forming the feature description of the entire block, it also includes: calculating the density of each histogram in the corresponding block, and then normalizing each unit in the block according to the calculated density. Specifically, for the monitoring images of transport vehicles in transit in the monitoring area, a combination of contour features and vehicle signs is used to identify hazardous chemical vehicles. The specific identification process is as follows:

[0061] (a) Perform gamma correction on the image to reduce the image size and reduce the impact of image shadows and lighting on vehicle recognition. Then, divide the monitoring image into m×m blocks, and each block is divided into n×n units, with k×k pixels in each unit. By collecting the gradient or edge direction histogram of each pixel in the image unit and connecting these histograms in series, a feature description of the entire block is formed. The feature descriptions of each block in the image are then connected in series to form a feature description of the entire image, which is used as the feature vector for classification;

[0062] (b) At the same time, in order to improve the extraction speed and accuracy, the surveillance image needs to be contrast normalized first. The density of each histogram in this block is calculated first, and then each unit in the block is normalized according to this density;

[0063] (c) In the training of selecting weak classifiers, the weighted sample with the smallest error rate is selected and combined with the threshold as the currently selected weak classifier, and the weak classifier is re-weighted to the sample, and the optimal weak classifier is found through continuous training objectives:

[0064]

[0065] Where f is the feature, θ is the threshold, p is the sign of the classification direction, and w is the sub-window to be detected;

[0066] (d) During the classification algorithm training process, in addition to collecting and inputting a certain number of hazardous chemical vehicle outline samples, common hazardous chemical-related vehicle logo images are also collected and input;

[0067] (e) For the identified hazardous chemical vehicle, its license plate information is identified and obtained at the same time. License plate recognition is also performed according to the process of step (a) to step (c).

[0068] Furthermore, the stop point position includes a predicted trajectory set between two trajectory points obtained by a trajectory prediction model; and the distance between the two trajectory points is greater than or equal to a distance threshold.

[0069] Specifically, after obtaining a certain amount of trajectory data, the trajectory prediction model is further trained using a time recursive network. The Douglas-Peucker algorithm is used to compress the trajectory data and optimize the data quality. The trajectory data training set is imported, and the weight W is extracted after the training is completed. The trajectory prediction model can predict the vehicle trajectory when the trajectory data is incomplete. The two trajectory points X that the vehicle passes through i and X j , △d is the distance threshold, then trajectory prediction processing can be performed in the following two modes:

[0070] (a) If |X i -X j |≥<Δd, and there is no monitoring data of other trajectory points between the two trajectory points, then the trajectory prediction model is used to obtain the predicted trajectory set PX between the two trajectory points = {X p1 , X p2 , ..., X pm};

[0071] (b) If |X i -X j |<Δd, and at the trajectory point X j If there is no monitoring data for other trajectory points, then the trajectory prediction model can be used to obtain the trajectory point X j The predicted trajectory set PX = {Xp1 , X p2 , ..., X pm Based on the predicted trajectory set, the time attribute of the adjacent predicted points on the predicted trajectory is the time of the previous point plus the distance between the next adjacent point and the vehicle speed, and the predicted trajectory set is obtained.

[0072] The above solution integrates heterogeneous data from multiple sources (the positioning information of the corresponding corporate entity in the stop area of ​​the hazardous chemical vehicle, the registration information of the corresponding corporate entity and the transportation registration product information of the hazardous chemical vehicle), thereby avoiding inaccurate monitoring or early warning results caused by a single data source, and solving the recognition of the identification information of the hazardous chemical vehicle, thereby maximizing the coverage of the recognition range, improving monitoring efficiency, and more effectively identifying illegal production and operation of hazardous chemicals.
