Method Description:
SparseFormer is a high-performance LiDAR 3D object
detection framework built upon a sparse BEV
representation. It can effectively capture complex
local topologies and long-range contextual
information.
Parameters:
VOXEL_SIZE: [0.05, 0.05,
0.1]m;MAX_POINTS_PER_VOXEL: 10

Detailed Results

Object detection and orientation estimation results. Results for object detection are given in terms of average precision (AP) and results for joint object detection and orientation estimation are provided in terms of average orientation similarity (AOS).
