Abstract
A system and method for detecting movement of a non-light-of-sight (NLOS) object in a space outside a line-of-sight (LOS) of a camera is disclosed. The camera acquires a sequence of successive images that each include a set of pixels, at least a subset thereof representing a target, being at least part of a visible object located within the LOS of the camera and impacted by light scattered from the NLOS object. The set of pixels of two images of the sequence, acquired from different positions of the camera, are registered into a common coordinate system, giving rise to two registered images. A target light intensity value is calculated for both registered images based on at least part of the set of pixels representing the target in the respective registered image. Movement of the NLOS object is detected based on a variation in the target light intensity value between registered images.
