PCOC: A Fast Sensor-Device Line of Sight Detection Algorithm for Point Cloud Representations of Indoor Environments

This letter presents a novel algorithm for Sensor-to-Device Line of Sight (LoS) detection for point cloud representations of indoor scenarios. Perspective projection with region clipping is utilized to evaluate the relative position of an obstacle coordinate cloud with respect to the direct sensor-device visibility. Performance of the proposed algorithm is verified against the classical ray-voxel ...
