code explaination 3d, in fact 2d rotated bbox iou
Introduction 介绍 This is a code explaination of the IOU3D calculation in the codes.In fact the codes simplified the calculation of 3D iou by projecting 3D bbox to the ground plane and calculating the IOU of the 2D BEV bbox. 这是代码中IOU3D计算的代码解释。实际上，代码通过将3D bbox投影到地面平面并计算2D BEV bbox的IOU来简化了3D iou的计算。 The whole pipeline & pseudo-code 整体流程伪代码 Without concern for the NMS operation, 3D bboxes in codes can be split into modules below which can also be summarized with the pseudo-codes below....
