    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 distance camera includes at least one photo element, a trigger generator activating the photo element during a temporal integration gate, a light source illuminating an object with light pulses having a predetermined temporal intensity profile with a duration Tp, and an intensity sensor determining the intensity Ip of the light pulses arriving on the photo element. The integration gate has a predetermined delay to the light pulse emission start point in order to capture the light pulses back reflected from the object. The photo element outputs a signal value U at an integration end point in time T1e and in accordance with an intensity Ip and a duration of the light pulse arriving on the photo element during its activation.

    摘要: Systems and method for imaging through scattering media. One example of an imaging system includes an illuminator configured to produce a structured illumination pattern and to direct the structured illumination pattern into an imaging field through a scattering medium, a camera configured to receive reflections of the structured illumination pattern from an object in the imaging field and to provide corresponding image data, a master oscillator coupled to the illuminator and to the camera and configured to modulate the structured illumination pattern and to clock the camera so as to time gate the reflections of the structured illumination pattern and provide signal timing data, and a processor coupled to the camera and received to receive and process the image data and the signal timing data to produce an image of the object.

    摘要: Active-gated imaging system and method for imaging environment with at least one high-intensity source. A light source emits light pulses toward the environment, and an image sensor with a pixelated sensor array receives reflected pulses from a selected depth of field and generates a main image. The image sensor exposure mechanism includes a pixelated transfer gate synchronized with the emitted pulses. An image processor identifies oversaturated image portions of the main image resulting from a respective high-intensity source, and interprets the oversaturated image portions using supplementary image information acquired by image sensor. The supplementary information may be obtained from: a low-illumination secondary image having substantially fewer gating cycles than the main image; by accumulating reflected pulses from the high-intensity source after the reflected pulses undergo internal reflections between optical elements of the camera; or a low-illumination secondary image acquired by residual photon accumulation during a non-exposure state of image sensor.

    摘要: A method and a system for inertial measurement. The method includes controlling at least one imaging sensor to capture at least two consecutive images, processing the at least two consecutive images to identify at least one feature therein and determining at least one parameter associated with the at least one feature, and determining a change in a position and an orientation of the at least one imaging sensor, based upon the at least one parameter associated with the at least one feature. The at least one parameter includes at least one of: a presence or absence of the at least one feature in at least one of the at least two consecutive images, respective pixel locations of the at least one feature in the at least two consecutive images, and/or three-dimensional locations of the at least one feature with respect to the at least one imaging sensor.
