Abstract
A 3D object detection method based on multi-view feature fusion of 4D RaDAR and LiDAR point clouds includes simultaneously acquiring RaDAR point cloud data and LiDAR point cloud data; and inputting the RaDAR point cloud data and the lidar point cloud data into a pre-established and trained RaDAR and LiDAR fusion network and outputting a 3D object detection result, wherein the RaDAR and LiDAR fusion network is configured to learn interaction information of a LiDAR and a RaDAR from a bird's eye view and a perspective view, respectively, and concatenate the interaction information to achieve fusion of the RaDAR point cloud data and the lidar point cloud data. The method can combine advantages of RaDAR and LiDAR, while avoiding disadvantages of the two modalities as much as possible to obtain a better 3D object detection result.
