| 요약 | Coded structured light is one of the most effective and reliable techniques for surface reconstruction. With a calibrated projector-camera stereo system, a set of illuminating patterns are projected onto the scene by projector and the image is captured by the camera. The correspondences between projector and camera frames are calculated in the decoding process, which is used for triangulation and point cloud generation. Continuous phase shifting method is a well-known fringe projection technique for 3D scanning. A set of sinusoidal patterns showing variation of intensity or color are projected onto the surface. This proposal, introduces a novel circular phase shifting method to improve the decoding accuracy, without the trade-off between the processing speed and decoding accuracy. In the proposed approach, three-step circular phase shifting and absolute patterns are used for increasing the multiplicity since the circular patterns are coded in all directions. The stereo triangulation is more stable and accurate than line-plane intersection used in single axis structured light methods by reducing incorrect decoding errors. Robust gray patterns are applied to resolve the ambiguity resolution caused by reflectance discontinuities in the phase shifting decoding process. |
