Scan Pattern Characterization of Velodyne VLP-16 Lidar Sensor for UAS Laser Scanning [PDF]

open access: yesSensors, 2020
Many lightweight lidar sensors employed for UAS lidar mapping feature a fan-style laser emitter-detector configuration which results in a non-uniform pattern of laser pulse returns. As the role of UAS lidar mapping grows in both research and industry, it
