Abstract

The invention discloses a vehicle identity recognition method and device. The method comprises the steps of obtaining an original image of a vehicle to be recognized; obtaining a vehicle position fromthe original image according to a vehicle position recognition model; obtaining identity information of the vehicle according to the vehicle position and the brand recognition model, wherein the vehicle identity information comprises a vehicle brand, and the vehicle position recognition model is based on a deep neural network. The vehicle position recognition model is based on the deep neural network, the complexity of the model based on the deep neural network algorithm is lower, the operation acceleration can be conducted through the GPU, the training speed of the model is increased, meanwhile, the classification speed and the accuracy of the model are improved, and therefore the vehicle identity recognition precision is improved.

Description

Technical field [0001] The invention relates to the field of transportation. More specifically, the present invention relates to a vehicle identification method and device. Background technique [0002] Vehicle identification is of great significance to traffic safety issues, and vehicle brand is an important part of vehicle identity, which plays an extremely important role in the investigation of accident-causing vehicles and automatic detection of unlicensed vehicles. [0003] Vehicle brand recognition can include vehicle positioning and brand recognition in the image. Vehicle positioning is to identify the vehicle from the background. There are hundreds of existing vehicle brands, some of which have relatively small differences, and the existing vehicle brand identification methods are prone to identification errors. Summary of the invention [0004] The purpose of the present invention is to provide a vehicle identification method, which improves the accuracy of vehicle identi...
