Deep learning-based vehicle detection method

Abstract

The invention discloses a deep learning-based vehicle detection method which is used for conducting vehicle detection in a complex environment by combining Edge Boxes and an improved Faster R-CNN model. The method comprises the steps that an image is processed by using the Edge Boxes, and an accurate vehicle candidate area is extracted primarily; and then the candidate area is input to the improved Faster R-CNN model to achieve precise positioning on vehicles, and a final detection result is obtained through classification and discrimination. In order to enhance the detection capacity on the small-size vehicles by the model and the discrimination capacity of the model, different layers of convolutional features are combined, some detail information of the vehicles is supplemented, a difficult negative sample mining strategy is added in the training stage, therefore, the model can pay more attention on difficult samples, and the vehicles can be well distinguished with the backgrounds ofsuspected vehicles.

Description

Technical field [0001] The invention belongs to the technical field of computer vision recognition, and specifically relates to a vehicle detection method based on deep learning. Background technique [0002] Vehicle detection is an indispensable link in the intelligent transportation system. Effective road traffic information is collected through vehicle detection methods to obtain basic data such as traffic flow, vehicle speed, road occupancy, vehicle spacing, vehicle type, etc., to achieve monitoring purposefully , Control, analysis, decision-making, dispatching and diversion to maximize traffic resources, thereby improving the robustness and robustness of the entire intelligent transportation system. Current mainstream vehicle detection methods use HOG and SIFT methods to extract features of vehicles, and input the extracted features to support vector machines (SVM), iterators (AdaBoost) and other classifiers for vehicle detection. These methods essentially rely on artificia...
