ステレオビジョン、別名ステレオセプシスは、視覚の一つです perception mechanism that allows individuals to perceive depth and three-dimensional (3D) structures by integrating two slightly different images from each eye. This phenomenon occurs because human eyes are spaced apart, causing each eye to view an object from a different angle. The brain processes these two images and combines them to create a single, cohesive view, enabling depth perception.
目と目の間の距離は、通常成人で約6.5センチメートル（2.5インチ）であり、立体視において重要な役割を果たします。脳は、画像間の差異（各目から見た物体の位置の違い）を利用して距離を測定します。この過程は「両眼視差」と呼ばれます。差異が大きいほど、物体は近くに見え、差異が少ない場合は遠くにあることを示します。
Stereo vision is essential for various daily activities, such as driving, playing sports, and navigating through environments. It enhances our ability to judge distances accurately and interact with the world around us. In the 人工知能の分野 and computer vision, stereo vision is a significant area of research, focusing on how machines can replicate this human capability. Techniques such as stereo matching and 深度推定などの技術があります are employed to allow computers to interpret spatial information from two-dimensional images similarly to human vision.
In addition to its application in robotics and AI, stereo vision technology is also used in various industries, including virtual reality (VR), 拡張現実 (AR), and 3D movie production, where creating a convincing sense of depth is crucial for immersive experiences.
