Dynamic voxelization
WebJun 2, 2024 · Here, we formally define the lidar-based 3d object detection task as follows: given point cloud of a scene formed by the returned lidar points (represented in the lidar coordinate frame), predict oriented 3d bounding boxes (represented in the lidar coordinate frame) corresponding to target actors in the scene. WebFigure 1: Illustration of the differences between hard voxelization and dynamic voxelization. The space is devided into four voxels, indexed as v 1, v 2, v 3, v 4, which …
