    DMP-KDO-PCLoSA: a LiDAR point cloud visibility analysis method for urban remote sensing using depth map projection and KNN optimization by Jianghong Zhao, Yihong Zhang, Ailin Xu, Xueqing Zhang, Yingyi Zhang, Shuhan Guo

    Published 2025-12-01

    Accurate line-of-sight (LoS) analysis in LiDAR point clouds is vital for urban remote sensing and geospatial applications, yet sparse and occluded data challenge reliability. We propose DMP-KDO-PCLoSA, a novel method integrating Depth Map Projection (DMP) with K-Nearest Neighbour Depth Optimization...
