Local Grid Rendering Networks for 3D Object Detection in Point Clouds

4 Jul 2020Jianan LiJiashi Feng

The performance of 3D object detection models over point clouds highly depends on their capability of modeling local geometric patterns. Conventional point-based models exploit local patterns through a symmetric function (e.g. max pooling) or based on graphs, which easily leads to loss of fine-grained geometric structures...
