ProFace X (SL) adopts the pioneering 3D Structured Light technology for Facial Recognition. This 3D surface imaging technique calculates 3D data in the real world, such as the depth and distance, by actively projecting light spots to a target and calculates the disparity between the original projected patterns and the observed light coding patterns deformed by the surface. Benefited from the power of the structured light to conduct liveness detection with 30,000 projected laser dot arrays, the terminal’s anti-spoofing ability has been hugely enhanced, powerfully against 100% print and video attacks.
