Abstract

The invention relates to the technical field of computers, and particularly provides a vehicle image clustering and trajectory restoration method. The vehicle image clustering method comprises the following steps: extracting vehicle information and license plate information of a target vehicle from a to-be-processed image containing the target vehicle; determining a candidate image set based on the vehicle information and the license plate information; and based on the similarity between each candidate image in the candidate image set and the to-be-processed image, performing clustering processing on the to-be-processed image to obtain a clustering result of the to-be-processed image. According to the method, the clustering precision and efficiency of the vehicle images are improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to a vehicle image clustering and trajectory restoration method and device. Background technique [0002] Vehicle trajectory restoration technology can be used to obtain the trajectory of vehicles running in the city, so that traffic data can be sensed and analyzed. Common applications include high-speed vehicle escape, vehicle driving behavior analysis, etc. In the related art, the vehicle trajectory restoration system often needs to perform clustering processing on the vehicle image of the target vehicle first, but the accuracy and efficiency of the clustering processing in the related art are low, and it is difficult to meet the use requirements. Contents of the invention [0003] In order to improve the accuracy and efficiency of vehicle image clustering processing, embodiments of the present disclosure provide a vehicle image clustering method, a vehicle trajectory...
