Abstract: A mechanism is described for facilitating code filters for coded light depth acquisition in depth images at computing devices according to one embodiment. A method of embodiments, as described herein, includes detecting a code image of an object comprising pixels of code values and pixels of metadata values including confidence and code transition locations, and computing a vertical filter to be applied to the code image to smooth out the code transitions along vertical directions. The method further include computing a horizontal filter to be applied to the code image to smooth out the code transitions along horizontal directions, and computing a consistency filter to be applied to the code image to increase an accuracy of the code values and mark inconsistent pixels as invalid. The method may further include applying at least one of one or more of the vertical filter, the horizontal filter, and the consistency filter to filter the digital image, and outputting the filtered code image comprising filtered code values and filtered metadata values.

Abstract: A method and apparatus for projector distortion compensation in structured light depth reconstruction are described. In one embodiment, the apparatus comprises a projector configured to project a sequence of light patterns on an object; a first camera configured to capture a sequence of images of the object illuminated with the projected light patterns; a processing unit to receive the sequence of images and reconstruct depth using triangulation in response to camera and projector location coordinates; and a projector distortion compensation unit operable to generate a new projector location coordinate in response to an observed distorted projector location coordinate, the projector distortion compensation unit to provide the new projector location coordinate to the processing unit for use in generating depth values via triangulation.

Abstract: Example range estimation apparatus disclosed herein include a first signal processor to estimate a signal power parameter and a noise power parameter of a LIDAR system based on first data to be output from a light capturing device of the LIDAR system. Disclosed example range estimation apparatus also include a second signal processor to generate templates corresponding to different possible propagation delays associated with second data to be output from the light capturing device, the second data associated with a modulated light beam projected by the LIDAR system, the templates generated based on the signal power parameter and the noise power parameter, and the second data to have a higher sampling rate and a lower quantization resolution than the first data. In some examples, the second signal processor is also to determine, based on the templates, an estimated propagation delay associated with the second data.
