| description | 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.
