Abstract

The invention discloses a vehicle type recognition method based on a convolutional neural network under the vehicle-mounted environment. A semantic compact bilinear pooling method for vehicle type recognition is put forward, which combines the hierarchical tag tree and compact bilinear pooling and demonstrates superior performance on the CompCars data set and the Stanford auto data set. With application of the method, the compact bilinear pooling method uses semantic connection between different levels of semantics of the vehicle and makes them mutually enhanced during training. The softmax loss function is promoted to the loss avoidance function aiming at making full use of prior knowledge. Experiments show that the invention improves the accuracy of the vehicle type recognition task on the CompCars data set and the Stanford auto data set.

Description

technical field [0001] The invention relates to a target classification method based on the field of computer vision, mainly an improved vehicle identification method based on a caffe depth framework and a convolutional neural network. Background technique [0002] Deep learning and Convolutional Neural Networks (CNNs) have achieved astounding achievements in public safety in recent years. In public security systems, car-related tasks account for a large portion of all computer vision tasks. At present, license plate recognition has been widely used in traffic safety systems, and vehicle vehicle recognition has become an increasingly popular task in the field of computer vision. In 2013, Krause et al. released a dataset for car model recognition (Stanford Car Dataset). And various research works have been done in the field of computer vision for vehicle recognition. Compared with the recognition or classification of other general objects such as face recognition and Image...
