根据《Pointpillars: Fast encoders for object detection from point clouds.》一文介绍,Pillar-based这种点云表达形式忽略了沿Z轴的划分,3D空间[L,W,H]划分为固定大小的柱子[uL,uW,H]。直观来讲,柱子被视为沿Z轴的未绑定体素。与体素化类似,将点分配给柱子是通过固定体素化、动态体素
Various systems and methods for implementing LiDAR-based object detection and classification are described herein. An object detection system includes a feature extraction and object identification (FEOI) circuit to: receive segmented data of an environment around the object detection system, the ...
Point-voxel based methods 基本框架: a hybrid architecture that leverages both points and voxels for 3D object detection. 主要可分为single-stage (依靠backbone里的point-to-voxel和voxel-to-point转换来bridge the features of points and voxels)和two-stage。 问题与挑战: 对于hybrid point-voxel backbones...
