View-Agnostic Point Cloud Generation for Occlusion Reduction in Aerial Lidar

Remote Sensing, 2022
Occlusions are one of the leading causes of data degradation in lidar. The presence of occlusions reduces the overall aesthetic quality of a point cloud, creating a signature that is specific to that viewpoint and sensor modality.
