    摘要: It relates to methods, devices and systems for transparent object three-dimensional reconstruction. The system (10) comprises a structure light generation module (110), an image acquisition module (120), a control module (130) and a computing module (140). The computing module (140) acquires image pairs from the image acquisition module (120); calculates three-dimensional positions of points according to the image pairs; and performs refinement process to extract first-reflection points. The refinement process comprising: when reflection points are obtained by a first camera (122), the points include a first point and a second point, the first point is closer to reflection spot of laser on galvanometer mirror (114) than the second point, remove the second point; when the first point is not obtained by a second camera (124), remove the first point; when the second point is obtained by the second camera (124), retrieve the second point, and when a discrete external virtual contour is formed, remove the discrete external virtual contour.

    摘要: One example provides a computing system comprising a depth sensor comprising a plurality of pixels, and a storage machine holding instructions executable by a logic machine to, for each pixel, make K phase measurements to form a set of noisy phase measurements, determine a location at which a projection line that passes through the set of noisy phase measurements in a K-dimensional phase space passes through a lower dimensional plane, the projection line being parallel to a noise free phase evolution line, compare the location to a plurality of independent terms of a predetermined matrix of points in the lower dimensional plane, locate a corresponding set of noiseless phase orders by using a selected set of independent terms to reference a look-up table, determine a distance value for the pixel based upon the corresponding set of noiseless phase orders, and output the distance value for the pixel.

    摘要: A system for single photon avalanche diode image capture is configurable to, over a frame capture time period, selectively activate an illuminator to alternately emit light from the illuminator and refrain from emitting light from the illuminator. The system is configurable to, over the frame capture time period, perform a plurality of sequential shutter operations to configure each SPAD pixel of the SPAD array to enable photon detection. The plurality of sequential shutter operations generates, for each SPAD pixel of the SPAD array, a plurality of binary counts indicating whether a photon was detected during each of the plurality of sequential shutter operations. The system is configurable to, based on a first set of binary counts of the plurality of binary counts, generate an ambient light image. The system is configurable to, based on a second set of binary counts of the plurality of binary counts, generate an illuminated image.
