Abstract
Method for determining a disparity value of a disparity of each of a plurality of points on an object, the method including the procedures of detecting by a single image detector, a first image of the object through a first aperture, and a second image of the object through a second aperture, correcting the distortion of the first image, and the distortion of the second image, by applying an image distortion correction model to the first image and to the second image, respectively, thereby producing a first distortion-corrected image and a second distortion-corrected image, respectively, for each of a plurality of pixels in at least a portion of the first distortion-corrected image representing a selected one of the points, identifying a matching pixel in the second distortion-corrected image, and determining the disparity value according to the coordinates of each of the pixels and of the respective matching pixel.
