Lateral disparity

As lateral disparity also Querdisparität , is defined as the difference between the image position on the retina of the right and left eye , through the eye spacing (mm in man about 50 to 70 mm) arises, and thus of its vergence depends.

The visual system has the ability to obtain information for spatial vision from the diversity of these two-dimensional images. The result is called stereoscopic vision , cf. also deviation .

A distinction is made between crossed transverse disparity and non-crossed transverse disparity. One speaks of crossed transverse disparity when objects lie in front of the horopter and thus fall on the outer edge of the retina . One speaks of uncrossed transverse disparity when objects lie behind the horopter and thus fall on the inner edge area of ​​the retina.
