Abstract

The invention provides a vehicle type identification method and device. The vehicle type identification method includes: obtaining the overall vehicle picture, and segmenting the vehicle to obtain thelocal pictures of the multiple different parts; splicing the local pictures of the different parts of the vehicle into a large picture according to the positions corresponding to the different parts;and sending the spliced large graph into a neural network model to extract features, and classifying vehicles according to the extracted features. According to the vehicle type identification methodand device provided by the invention, the vehicle type identification rate at different shooting angles is improved; compared with the prior art that the global image features and the local image features of the vehicle are respectively extracted through a plurality of convolutional networks and then fused, the calculation steps and the calculation amount are reduced.

Description

technical field [0001] The present application relates to the field of image recognition, in particular, to a vehicle type recognition method and device. Background technique [0002] At present, the identification of vehicle types is mainly aimed at pictures of a specific angle of the vehicle. If the angle changes, the recognition accuracy drops sharply. At the same time, to identify the type of vehicle, the traditional method is to design multiple convolutional networks, one convolutional network extracts global image features, other networks extract local image features, and then fuses global image features and local image features. The traditional method has cumbersome steps and a large amount of calculation, which cannot meet the application scenarios that need to quickly identify the type of vehicle. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of this application is to provide a vehicle type...
