Scene recognition for 3D point clouds: a review
Intelligent robots can perform several high-risk tasks such as object detection and epidemic prevention to aid human beings. Research on scene recognition has attracted considerable attention in recent years. Scene recognition aims to obtain high-level semantic features and infer the location of a scene, laying a good foundation for simultaneous localization and mapping, autonomous driving, intelligent robotics, and loop detection. With the rapid development of 3D scanning technology, obtaining point clouds of various scenes using various scanners is extremely convenient. Compared with images, the geometric features of point clouds are invariant to drastic lighting and time changes, thus making the process of localization robust. Therefore, scene recognition of point clouds is one of the most important and fundamental research topics in computer vision. This paper systematically expounds the progress and current situation of scene recognition techniques of point clouds, including traditional methods and deep learning methods. Then, several public datasets for scene recognition are introduced in detail. The recognition rates of various algorithms are summarized. Finally, we note the challenges and future research directions of the scene recognition of point clouds. This study will help researchers in related fields to better understand the research status of scene recognition of point clouds quickly and comprehensively and lay a foundation for a further improvement in the recognition accuracy.
