Vehicle model identification method and device and medium

The invention discloses a vehicle type identification method and device and a medium, and is applied to the field of intelligent transportation. The vehicle model identification method provided by the invention comprises the following steps: carrying out feature extraction on each to-be-detected region image block obtained by carrying out component detection on a to-be-detected vehicle through a feature extraction model obtained by carrying out preset region spliced image training, thereby obtaining a to-be-detected spliced image, and carrying out vehicle model identification on the to-be-detected vehicle through the to-be-detected region image block. And obtaining to-be-detected features obtained through feature extraction, and performing feature comparison on the to-be-detected features to determine the vehicle type corresponding to the to-be-detected vehicle. According to the technical scheme, the training samples of the feature extraction model obtained through the training of the preset area spliced grap
