Fake-licensed vehicle identification method and device, storage medium and terminal

Abstract

The invention discloses a fake-licensed vehicle identification method and device, a storage medium and a terminal. The method comprises the following steps: extracting a vehicle passing record set associated with a to-be-identified target license plate in a preset time period; obtaining a license plate recognition moment in each vehicle passing record in the vehicle passing record set; sorting the vehicle passing records according to the sequence of the obtained license plate recognition moments, and generating a track time sequence; identifying an abnormal time sequence contained in the track time sequence, and eliminating the identified abnormal time sequence from the track time sequence to generate a target track time sequence; performing hierarchical spatial clustering on the target trajectory time sequence to generate at least one trajectory fragment; and determining whether a fake-licensed vehicle has the target license plate to be identified based on the at least one track fragment. Therefore, according to the embodiment of the invention, the track fragment of the fake-licensed vehicle is determined by analyzing the track time sequence of the license plate to be identified, so that the identification accuracy of the fake-licensed vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method, device, storage medium and terminal for identifying vehicles with license plates. Background technique [0002] A licensed vehicle refers to a vehicle that illegally uses the license plate of another person's motor vehicle. In recent years, with the rapid development of the economy, the number of motor vehicles in cities has increased day by day, and the phenomenon of license plate vehicles has become increasingly rampant. The behavior of playing cards not only caused the loss of state fees, but also damaged the interests of car owners. At the same time, it also disrupted the normal traffic order and brought certain unstable factors to the society. Therefore, it is an urgent need to improve traffic law enforcement capabilities and maintain social fairness and justice by discovering and identifying the phenomenon of vehicle license plates.

Problems solved by technology

The above scheme has played a great role in the discovery and management of license plate vehicles, but it also has certain shortcomings: in terms of function, the above scheme pays more attention to the judgment of whether the license plate is applied, but ignores the stripping of vehicle trajectories of different license plates , and the stripping of the trajectory can precisely answer more detailed questions, such as how many vehicles the license plate is applied to and where the licensed vehicles are distributed, as well as the driving trajectory of the vehicle, etc. The mining of the above detailed information will be more helpful. It is based on the evidence collection and management of licensed vehicles by public security organs; in terms of methods, more attention is paid to the rationality of the spatial dimension distribution of vehicles, but the hidden characteristics of vehicle trajectories as time series data, coupled with the errors introduced by sensing equipment, are ignored. This often affects the calculation efficiency and calculation accuracy of the algorithm, thereby reducing the accuracy of vehicle identification
