Stereo Vision

A computer vision technique that uses two or more cameras positioned at slightly different viewpoints to extract three-dimensional depth information from a scene, mimicking the way human binocular vision perceives depth. In assistive technology, stereo vision systems have been used to capture 3D data about real-world objects and environments for conversion into tactile or auditory representations accessible to blind users. Stereo vision can provide richer spatial information than single-camera systems, enabling applications such as obstacle detection for navigation, 3D object recognition for environmental awareness, and generation of tactile surface maps showing object depth and shape.
