HOG and SVM algorithm based on vehicle model recognition

With the rapid development of machine learning, computer vision and other artificial intelligence technologies, vehicle identification based on image processing, pattern recognition and other technologies has attracted more and more attention and research As an important part of intelligent transportation system, vehicle type identification plays an important role in traffic management, campus entrance guard and other scenarios. This paper proposes a HOG feature based vehicle model recognition algorithm for the recognition of road passing vehicles. First, HOG feature vector of vehicle samples is extracted through HOG algorithm. Then, SVM classifier is used to train the HOG feature vector of training samples. The HOG feature vector of test samples is put into SVM classifier to obtain the classification result of test samples. In this paper, according to the wheelbase and displacement classification, the vehicle types are divided into: micro car, small car, compact car, medium car, medium and large car, luxury car, MPV, SUV, minivan nine types and establish training samples and test sample model library, the overall recognition success rate is 93.6893%.
