I need accuracy requirements, which 3D scanner is better?

The 3DCaMega optical 3D scanning system portable CPC binocular 3D scanner is based on the principle of structured light binocular vision and is highly integrated with two digital cameras, a structured light projector and a central control circuit "optical electromechanical". The system projects multiple groups of grating stripes onto the object surface; two digital cameras simultaneously capture the stripe patterns on the object surface from different angles, and input the stripe images into the computer; the computer analyzes the stripe curvature changes based on the phase method and trigonometric method, and accurately calculates each The pixels correspond to the spatial coordinates (X, Y, Z) of the object surface, and the three-dimensional point cloud data (Point Cloud) of the object surface is obtained.
