Abstract:To solve the problems of insufficient detection accuracy of the target detection algorithm based on single sensor and slow detection speed of the multisensor fusion algorithm based on image and lidar, a vehicle target detection algorithm was proposed based on the fusion of lidar and millimeter wave radar. The depth information of lidar point cloud and the target information of millimeter wave radar were fully used, and the normalization method was adopted to preprocess the point cloud for generating feature maps. The millimeter wave radar data were fused to generate interested regions, and a multitask classification regression network was designed to achieve vehicle target detection. The training verification was performed on Nuscenes large data set. The results show that the detection accuracy can reach 6052%, and the point cloud detection takes 35 ms per frame. The proposed algorithm can meet the accuracy and realtime requirements of intelligent driving vehicles for vehicle target detection.
