摘要： Methods and systems are provided, which illuminate a scene with pulsed patterned light having one or more spatial patterns; detect reflections of the pulsed patterned light from one or more depth ranges in the scene, by activating a detector for detecting the reflections only after respective traveling times of the illumination pulses, which correspond to the depth ranges, have elapsed; and derive an image of the scene from the detected reflections and according to the spatial patterns. The methods and systems integrate gated imaging and structured light synergistically to provide required images which are differentiated with respect to object ranges in the scene and different patterns applied with respect to the objects and their ranges.

摘要： A method for detecting objects in a scene using a synchronized illuminating and sensing process is provided herein. The method includes the following steps: illuminating a light beam along an illumination line within a scene; sensing reflections of said light, wherein said reflections come from objects located within a specified depth of field within said scene, along a sensing line; generating a tempo spatial synchronization between the illumination line and the sensing line, wherein said synchronization determines said depth of field; relatively shifting at least one of: the illuminating line, and the sensing line, based on said tempo spatial synchronization; and accumulating said reflections, thereby detecting said objects.
