为了对大尺寸被测物体进行重构, 利用改进的Stoilov算法, 提出了结合拼接进行重构的方案。讨论的方法分为两种: (1)先对变形光栅条纹进行图像拼接, 再用Stoilov算法重构；(2)先分别对多组光栅条纹三维重构, 再进行轮廓拼接。实验结果表明, 两种方法均能比较好地对大尺寸被测物进行三维重构, 且各有优缺点。

In order to reconstruct the three-dimensional online shape of large object, a scheme combining stitching based on the improved Stoilov algorithm is presented. It involves two methods. The first method is that the deformed grating fringe is performed image mosaic at first, and then it is reconstructed by Stoilov algorithm. The second method is that three-dimensional construction is performed to multi-group of grating fringe respectively, and then contour mosaic is performed. Experimental results show that the two methods have better three-dimensional reconstruction capability to large objects and both have advantages and disadvantages.
