这允许模型在保持先前在3D任务中学到的特征的同时,通过微调视觉提示来优化2D检测性能。 第一阶段就是直接backbone输出到3D Detection;第二阶段就是backbone输出到2D Detection 视觉Prompt:类似padding设计;给定C*W*H的特征图,将2个C*(a*H)*W的patch加入特征图的顶部和底部。对于2D检测分支的训练,仅更新a和2D检测...
FCOS LiDAR的总体架构类似于基于2D图像的检测器FCOS[TSCH19]。通过将距离图像作为输入,网络获得多层次FPN特征,然后将分类和回归分支附加到这些特征层次以预测最终的3D盒。与FCOS不同,如第3.4节所述,探测头的权重不在FPN层之间共享。此外,FCOS中使用了类特定的回归头,而不是类不可知的回归头。
3D object detection is a fundamental problem in the space of autonomous driving, and pedestrians are some of the most important objects to detect. The recently introduced PointPillars architecture has been shown to be effective in object detection. It voxelizes 3D LiDAR point clouds to produce a ...
