A depth data measurement device, and a corresponding application method are disclosed. The measurement device includes: a projection assembly for projecting linear light onto an imaging object in relative motion; an image sensor for imaging based on the reflected light of the linear light, the each pixel sending a valid signal with a timestamp when the change in the amount of light received per unit time exceeds a threshold; and a processor for calculating the surface depth information of the object based on the positions of pixels corresponding to the valid signals, the timestamps of those valid signals, as well as the relative motion information. The present invention employs linear light to achieve active illumination and imaging of an object undergoing relative motion, and combines an image sensor in which each pixel can independently generate a valid signal when the brightness changes, so that imaging can be performed only for the valid signal, and the timestamp and relative motion information are used to determine the position of the depth data, thereby realizing high-speed depth information acquisition and processing with a simple projection mechanism and extremely low computing power requirements.

Systems and methods for estimating depth from projected texture using camera arrays are described. A camera array includes a conventional camera and at least one two-dimensional array of cameras, where the conventional camera has a higher resolution than the cameras in the at least one two-dimensional array of cameras, an illumination system configured to illuminate a scene with a projected texture, where an image processing pipeline application directs the processor to: utilize the illumination system controller application to control the illumination system to illuminate a scene with a projected texture, capture a set of images of the scene illuminated with the projected texture, and determining depth estimates for pixel locations in an image from a reference viewpoint using at least a subset of the set of images.
