第一次使用点云数据处理3D目标检测问题。 

作者的观点：

1. 以前的工作过于依赖2D检测性能，没有充分利用3D信息。

their follow-up work applied PointNet in 3D object detection to estimate the 3D bounding boxes based on the cropped frustum point cloud from the 2D RGB detection results. However, the performance of the method heavily relies on the 2D detection performance and cannot take the advantages of 3D inf
