Abstract

A method for depth mapping of objects in a scene by a system of a moving/movable platform is disclosed. According to some embodiments, the method includes actively illuminating the scene with pulsed light that is generated by at least one pulsed light illuminator and receiving, responsive to illuminating the scene, reflections on at least one image sensor that comprises a plurality of pixel elements. The method may further include gating at least one of the plurality of pixel elements of the at least one image sensor for converting the reflections into pixel values for generating reflection-based images that have at least two depth-of-field ranges and an overlapping DOF region. In addition, the method may include determining, based on at least one first pixel value of a first DOF in the overlapping DOF region, and based on at least one second pixel value of a second DOF in the overlapping DOF region, depth information of one or more objects located in the overlapping DOF region of the scene.
