| contents | The structured light projection technique is a representative active method for 3-D reconstruction, but many researchers face challenges with the intricate projector calibration process. To address this complexity, we employs an additional camera, temporarily referred to as the auxiliary camera, to eliminate the need for projector calibration. The auxiliary camera aids in constructing rational model equations, enabling the generation of world coordinates based on absolute phase information. Once calibration is complete, the auxiliary camera can be removed, mitigating occlusion issues and allowing the system to maintain its compact single-camera, single-projector design. Our approach not only resolves the common problem of calibrating projectors in digital fringe projection systems but also enhances the feasibility of diverse-shaped 3D imaging systems that utilize fringe projection, all without the need for the complex projector calibration process. |
