Stereo vision is the ability to perceive depth and three-dimensional structure from visual information. This occurs when each eye views a scene from slightly different angles, allowing the brain to combine these images into a single three-dimensional perception. This process is essential for tasks like judging distances and navigating through environments. The brain uses various cues, such as binocular disparity and convergence, to interpret the differences between the images received by each eye. Stereo vision is crucial for many activities, including driving, sports, and any task that requires depth perception. It enhances our understanding of the spatial relationships between objects.
