Depth perception is the ability to judge the distance and position of objects. It provides information about objects in the travel path and lane position. Monocular cues and binocular cues are used to extract depth information.
Depth perception is the ability to judge the distance of objects and their position in relation to oneself. It provides information about objects close to the travel path and lane position. There are two main ways to extract depth information: monocular cues and binocular cues.
Monocular depth cues are based on information within the two-dimensional visual field. For example, one object that overlaps another object must be in front of it. Size differences can also indicate distance. If a basketball appears larger than a basket, the basket must be further away.
Binocular cues compare information from the two retinae, as they do not see the visual field exactly the same. The brain can extract depth from the different spots objects of different distances fall on the two retinae. This allows us to perceive depth and judge the position of objects.
