Five aspects of researches about automatic drive perception by Waymo.

SPG：Unsupervised Domain Adaptation for 3D Object Detection via Semantic Point Generation

• targeted & light-weight model for improving LIDAR input quality against occlusions and poor weathers

• Effectiveness verified by applying to popular and SOTA 3D detectors.

• complete the 3D shape before Detection
