这种问题可分解为三步:1.根据长(l)宽(w)高(h)计算出一个和正向运动方向重合的3Dbbox的8个角点坐标向量:x_corners=[-l/2,-l/2,l/2,l/2,-l/2,-l/2,l/2,l/2]y_corners=[w/2,-w/2,-w/2,w/2,w/2,-w/2,-w/2,w/2]#z_corners=[0,0,0,0,h,h,h,h]#forkitti3ddatasetz_corners=[-h/2,-h/2,-h/2,-h/2,h/2,h/2,h/2,h/2]#forourlidar-coordination-baseddataset2.根据3Dbbox的朝向角(ro
