System and methods to efficiently measure stereoscopic disparity and to generate related mismatch images

摘要

Embodiments of the invention include a system and methods for measuring disparity and mismatch of stereoscopic images of three-dimensional video, which may indicate a level of discomfort on the part of the viewer. Measuring these parameters may also be used to give an indication that certain processes have or have not adversely effected perceived depth (i.e. through conversion from disparity to depth given a display size and viewing distance), verify camera setup or 2-dimension to 3-dimension synthesizing processes. Generating the indications and other data about the stereoscopic images uses techniques that allow processing with much less computing resources than was possible in previous systems.

主权项

1. A method, comprising:
accepting a left-eye image and a right-eye image of a stereoscopic image; creating a set of differential data from differences between at least a portion of the left image and at least a portion of the right image by performing a set of pixelwise comparisons between the portion of the left image to the portion of the right image in which, for each pixelwise comparison, the portion of the left image and the portion of the right image are incrementally shifted relative to each other; generating a two-dimensional mismatch image in which each pixel of a line of the mismatch image corresponds to one of the set of pixelwise comparisons; and assigning a color to each pixel of the mismatch image, in which the color is indicative of a level of match of the set of differential data.
