A4Vision's proprietary hardware for 3D face recognition works on the principle of structured or coded lighting. The main idea of structured lighting consists of projecting a pattern of known space structure. As the structured light is distorted by the individual facial geometry and these distortions are precisely defined by the shape of the scanned surface. (Learn More)
There are several hardware products that incorporate this innovative approach to 3D facial recognition which have been designed to meet the needs of the security and identification markets. Recent additions to the product line include the ability to simultaneously capture a color texture image with the 3D shape. This provides added capabilities for existing databases of 2D images. Touch screen PIN pads have been added for the PAC and Time and Attendance markets for built in dual factor authentication.
