Problems solved by technology
[0003] In order to solve the problem of difficult supervision of suspected vehicles suspected of changing license plates many times, the present invention provides a method based on similarity comparison to find the driving track of vehicles with license plates changed, which can extract suspected vehicles involving license plate violations without being affected by license plate changes The track of the suspected number plate, so that the supervision department can carry out follow-up work, reducing the human and material resources invested by the supervision department in the supervision work

The invention provides a method for finding the driving track of a license plate-changing vehicle based on similarity comparison, which can extract the track of a suspected license plate of a suspected vehicle involved in license plate violations without being affected by the license plate replacement, so that the supervision department can carry out follow-up work, reducing the The human and material resources invested by the regulatory authorities in the regulatory work. It includes S1: Identify and store the characteristic information of the vehicle through the feature intelligent recognition technology; S2: Identify the suspected license-related illegal vehicle; S3: Obtain the collection of all suspected license-related illegal vehicles; S4: Obtain the specified time within the specified range The set of features of all candidate vehicles in the section; S5: Use the vehicle features of a suspected illegal vehicle to calculate the similarity with the vehicle features of the candidate vehicle; S6: Traverse all suspected illegal vehicles to make them all After participating in the similarity calculation in step S5, the suspect vehicle set is obtained; S7: manually review the data in the suspect vehicle set for follow-up work.
Description
A method for finding the driving trajectories of vehicles with a license plate based on similarity comparison technical field The present invention relates to the technical field of intelligent traffic control, be specifically based on the comparison of similarity to find the driving of changing license plate vehicles track method. Background technique [0002] The license plate of a motor vehicle is a unique identifier for the management of motor vehicles by the national traffic management department. Existing various types of monitoring equipment automatically capture vehicle pictures, and then use vehicle feature intelligent recognition technology to identify the vehicle's characteristics. After the characteristic information such as the license plate, brand model and color, the related license plate can be analyzed by comparing it with the motor vehicle registration information. Illegal suspect vehicle. However, some vehicles with illegal license plates will chang...
