The method for vehicle appearance feature recognition includes: multiple region segmentation results of a target vehicle are obtained from an image to be recognized; global feature data and multiple pieces of region feature data are extracted from the image to be recognized based on the multiple region segmentation results; and the global feature data and the multiple pieces of region feature data are fused to obtain appearance feature data of the target vehicle. 1. A method for vehicle appearance feature recognition , comprising:obtaining a plurality of region segmentation results of a target vehicle from an image to be recognized;extracting global feature data and a plurality of pieces of region feature data from the image to be recognized based on the plurality of region segmentation results; andfusing the global feature data and the plurality of pieces of region feature data to obtain appearance feature data of the target vehicle,wherein the fusing the global feature data and the plurality of pieces of region feature data comprises:fusing the global feature data and the plurality of pieces of region feature data of the target vehicle by means of a third neural network for feature fusion,wherein the third neural network has a first fully connected layer, a third computing layer, and a second fully connected layer which are connected to an output end of a second neural network,wherein the fusing the global feature data and the plurality of pieces of region feature data of the target vehicle by means of a third neural network for feature fusion comprises:obtaining weight values of a plurality of first region feature vectors by means of the first fully connected layer;respectively weighting the plurality of first region feature vectors by means of the third computing layer according to the weight values to obtain corresponding a plurality of second region feature vectors; andperforming a mapping operation on the plurality of second region feature vectors and a ...
