Abstract
A method for multiple 3D sensor calibration for a passenger conveyance system, the process including a computing a centroid location from spatial measurements for each of a pair of 3D sensors that form a common field of view via a moving object mathematical model; computing translation parameters from the locations of each centroid location; and correcting one of the pair of 3D sensors to a common world coordinate system from the translation parameters.
