摘要: A three-dimensional surface contouring method is based on the full-field fringe projection technique. digital video system (18) used to project digitally created patterns onto object (12). The pattern distorted by geometry of (14) then captured a high resolution CCD camera (20). To increase resolution, purely software-based phase shifting technique used, which eliminates need for accurate positioning systems in traditional methods. reconstructed applying wrapping and unwrapping algorithms.
