自动驾驶汽车(autonomous vehicles,AVs)通过激光雷达等传感器实现对车辆周围环境的精细感知。然而,激光雷达(light detection and ranging,LiDAR)在恶劣天气条件下容易受到空气中如雨滴、雪花、雾等悬浮颗粒物的影响而产生数据噪声,进而降低汽车的感知能力,威胁车内人员的生命安全。为了解决这个问题,点云去噪技术被应用于激光雷达传感器。通过点云去噪技术,激光雷达能够获得更高质量的点云数据,从而提高汽车的感知能力。针对恶劣天气条件下激光雷达点云去噪这一关键技术问题,本文基于本团队近期的研究成果,结合近十年来的主流研究进展,介绍了恶劣天气点云公开数据集,按基于滤波器和深度学习两类方法详细阐述了点云去噪方法的技术发展,研判目前点云去噪领域所面临的挑战及未来发展方向。
Autonomous Vehicles (AVs) achieve precise perception of their surroundings through sensors such as Light Detection and Ranging (LiDAR). However, in adverse weather conditions, LiDAR is susceptible to noise caused by suspended particles in the air, such as raindrops, snowflakes, and fog, which degrades the vehicle’s perception capabilities and poses a threat to passenger safety. To address this issue, point cloud denoising techniques have been applied to LiDAR sensors. By leveraging these techniques, LiDAR can obtain higher-quality point cloud data, thereby enhancing the vehicle’s perception capabilities. To address the key technical challenge of point cloud denoising for LiDAR under adverse weather conditions, this paper draws on our recent research findings and incorporates mainstream research advances from the past decade to introduce public datasets of point clouds collected under adverse weather conditions. It provides a detailed analysis of point cloud denoising methods, categorized into filter-based and deep learning-based approaches.Lastly, it analyzes the current challenges and future research directions in point cloud denoising.
