Abstract
LiDAR ranging devices include an optical transmitter, and an optical receiver assembly. There is one LiDAR, and there can be more LiDARs each covering a field of sensing. The LiDAR devices are mounted within a building on a support structure in spaced relationship from each other. The fields of sensing from each LiDAR collectively provide an enhanced field of sensing of an area in the building. Each LiDAR and its base are tuned to sense human traffic. A base collects sensed data from each LiDAR such that tracking information and movement of human traffic over the enhanced area is received by the base. The fields of sensing of each LiDAR can overlap, and an analytic program stitches the sensed data from each LiDAR to obtain a stitched map of sensed data over the enhanced area. Barriers to line of site between humans to be sensed and LiDAR devices are minimized by the LiDARs.
