Title : Are we hungry of 3D Lidar Data for semantic segmentation? A new dataset SemanticPOSS and the researches at PKU-POSS
This talk will introduce the recent published SemanticPOSS dataset and give an overview of researches in PKU Intelligent Vehicle Group (POSS, http://www.poss.pku.edu.cn) on 3D LiDAR semantic scene understanding.
Nowadays, researches of 3D LiDAR semantic scene understanding mostly face the challenge of “data hungry”, especially for deep network based models. We will present our investigation results about the “data hungry” situation in the domain from different viewpoints.
The challenge of “data hungry” urges us to make the new dataset out of the ordinary: SemanticPOSS, which is a point-level point cloud dataset collected in Peking University. The main feature of this dataset is large quantity of dynamic instances inside. For example, the average instances of pedestrians are up to 8.29 per frame, which is more than 10 times denser than KITTI and SemanticKITTI.
The rich dynamic instances provide more challenging and diverse environment for autonomous driving system, and fill in some blanks of crowded dynamic scenes among public datasets.
By the way, we will introduce our work about 3D LiDAR semantic segmentation focused on solving “data hungry” problem. Concretely, weakly and semi-supervised learning algorithms applied to different scenarios will be presented.
