Binocular disparity and stereopsis
WebThis slight offset is termed retinal disparity. The brain can then interpret this offset as a binocular depth cue. Types of Stereopsis. Stereopsis can be broadly classified into two types - coarse stereopsis and fine stereopsis. Coase stereopsis is large, more easily distinguishable amounts of depth using retinal disparity cues. Binocular disparity refers to the difference in image location of an object seen by the left and right eyes, resulting from the eyes’ horizontal separation (parallax). The brain uses binocular disparity to extract depth information from the two-dimensional retinal images in stereopsis. In computer vision, binocular … See more Human eyes are horizontally separated by about 50–75 mm (interpupillary distance) depending on each individual. Thus, each eye has a slightly different view of the world around.

The brain combines the clear images from the left eye and right eye. It processes these two images as a single, three-dimensional image. This is called stereopsis. Stereopsis requires that both eyes see clearly.
