Embodiment Construction

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0028] At present, when re-identifying vehicles, all vehicle pictures regardless of direction are usually sent to the neural network as a data set for training. It is difficult to identify the same vehicle in different directions, resulting in misidentification of similar vehicles in the same direction and different vehicles. The knowledge rate is high. Based on this, embodiments of the present...

Abstract

The invention provides a vehicle re-identification method, a device and a system, which relate to the technical field of vehicle identification. The method comprises the following steps: obtaining a group of vehicle pictures to be identified; for each vehicle picture, the vehicle direction feature and the vehicle feature vector being extracted from the vehicle picture respectively; merging the directional feature and the vehicle feature vector into the fusion feature information of the vehicle; the fusion feature information of each vehicle being re-recognized, and the same vehicle being determined. The vehicle weight identification method, device and system of the invention greatly improve the accuracy of the vehicle weight identification and further improve the identification efficiencyby fusing the directional features of the vehicle and the vehicle features.

Description

technical field [0001] The present invention relates to the technical field of vehicle identification, in particular to a vehicle re-identification method, device and system. Background technique [0002] Among the many applications of video structuring, vehicle analysis is an important part, especially vehicle retrieval, tracking and other technologies, which are of vital significance in the field of security. [0003] Vehicle re-identification, also known as Vehicle Re-identification, or Reid for short, refers to using a vehicle image to find the vehicle in the image library or video library. For example, in a forensic application, it is necessary to find the car based on an image in a huge network of cameras in the city. [0004] At present, in the process of vehicle re-identification in the prior art, all the vehicle pictures are usually sent to the neural network as a data set for training, resulting in low recognition efficiency and recognition accuracy, and it is dif...
