3D vision, also known as three-dimensional vision or stereoscopic vision, is a multidisciplinary technology that combines computational graphics, computer vision, and artificial intelligence. It collects the three-dimensional coordinate information of each point in the field of view through the 3D camera, and obtains the three-dimensional image through the algorithm restoration. Compared with traditional 2D imaging technology, 3D vision technology is more stable, more experiential, and more secure.
