Moving Object Detection and Tracking with Doppler LiDAR [PDF]
Remote Sensing, 2019 In this paper, we present a model-free detection-based tracking approach for detecting and tracking moving objects in street scenes from point clouds obtained via a Doppler LiDAR that can not only collect spatial information (e.g., point clouds) but also

Detection and Tracking of Pedestrians Using Doppler LiDAR [PDF]
Remote Sensing, 2021 Pedestrian detection and tracking is necessary for autonomous vehicles and traffic management. This paper presents a novel solution to pedestrian detection and tracking for urban scenarios based on Doppler LiDAR that records both the position and velocity of the targets. The workflow consists of two stages. In the detection stage, the input point cloud
