Provided by the Springer Nature SharedIt content-sharing initiative. This chapter covers several topics that are important for a basic understanding of binocular vision and depth perception. These topics include the horopter, binocular disparity, binocular rivalry, spatiotemporal frequency effects, and distance scaling of disparity.When binocular disparity is unavailable, for example when one eye is patched, depth perception is strongly impaired. In such conditions, the defocus blur produced by an object out of an eye's plane of focus could potentially provide the visual system with the same information, since blur and disparity derive from the same geometry [ 2 ].Visual skills, such as binocular vision, accurate eye movements, and the ability to change focus to see near and distant objects, are necessary for observing, imitating, learning, playing, and more. ... Development of depth perception; Crawls to reach distant objects; Plays peek-a-boo; Watches and follows fast moving objects; 12 to 18 …Thus, empirical determination of the useful range of stereopsis is an open problem and a careful study is long overdue. This paper is a first step toward a characterization of stereopsis at moderate to large distances and focuses on binocular depth perception at moderate distances of 4.5 to 18.0 m.binocular form of depth perception. The location of an object in space is determined by two values: its direction and its distance relative to ourselves.
