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： Active or passive gated-sensor imaging system characterized by a minimized time period between successive sensor exposures. In the active imaging system, a light source emits light pulses toward a region of interest, and an image sensor receives reflections of the pulses reflected from objects located in a DOF to be imaged and converts the reflections into an image. Each frame of the image includes a plurality of gating cycles. Each gating cycle includes the emission of a respective light pulse and the reception of reflections of the respective pulse. A delay-time (T DELAY ) is defined as the duration between the sensor exposure periods of successive gating cycles. A controller controls the operation of the light source and the image sensor, to minimize the delay-time for at least one gating cycle of an image frame, where the delay-time is adaptively determined in accordance with at least one system parameter or environmental condition.
