Deep Learning for 3D Point Clouds: A Survey
It addresses the need for a survey to organize and stimulate research in deep learning for point clouds, which is incremental as it summarizes existing work rather than introducing new methods.
This paper provides a comprehensive review of recent progress in deep learning methods for 3D point clouds, covering tasks such as 3D shape classification, object detection, and segmentation, and includes comparative results on public datasets.
Point cloud learning has lately attracted increasing attention due to its wide applications in many areas, such as computer vision, autonomous driving, and robotics. As a dominating technique in AI, deep learning has been successfully used to solve various 2D vision problems. However, deep learning on point clouds is still in its infancy due to the unique challenges faced by the processing of point clouds with deep neural networks. Recently, deep learning on point clouds has become even thriving, with numerous methods being proposed to address different problems in this area. To stimulate future research, this paper presents a comprehensive review of recent progress in deep learning methods for point clouds. It covers three major tasks, including 3D shape classification, 3D object detection and tracking, and 3D point cloud segmentation. It also presents comparative results on several publicly available datasets, together with insightful observations and inspiring future research directions.
