Corresponding points are the points on the retina in which there is zero binocular disparity. The retinal positions of the various pairs of corresponding areas can be determined by projecting each point of the horopter upon the two retina in accordance with the principles of optical inversion.
Binocular disparity is the term given to the difference the fractional difference between an image that exists as a result of the eyes being marginally separated in their place on the face. The image that is received from each eye is just slightly different as a result of this place and must be appropriately processed by the brain into an integrated single image.
The correspondence problem is the problem associated with the process of how the visual perception system goes about finding a way to match pairs of images to arrive at vergence and then go about coding the relative depth of each into a unified image. The difficulty in solving the correspondence problem lies in the fact that a perfect correlation between the pairs of images can only be arrived at under very specific and unusual conditions.
Binocular disparity is related to motion parallax in that each is a method of measuring the perception of depth through the discrepancy that exists as a result of the disparity of image reception onto the retina due to the placement of the eyes. This difference in the position of the eyes is manipulated by the visual system through a process of triangulation that measures distance from the retina to an object and in order to integrate the slight disparity into a unified whole. ...
