PointAugmenting: Cross-Modal Augmentation for 3D Object Detection

no code implementations • CVPR 2021 • Chunwei Wang, Chao Ma, Ming Zhu, Xiaokang Yang

On one hand, PointAugmenting decorates point clouds with corresponding point-wise CNN features extracted by pretrained 2D detection models, and then performs 3D object detection over the decorated point clouds.
