Applying the iterative triangulation stitching algorithm, we provide an experimental demonstration by testing a Φ120 mm flat mirror, a Φ1450 mm off-axis parabolic mirror and a convex hyperboloid mirror. By comparing the stitching results with the self-examine subaperture, it shows that the reconstruction results are in consistent with that of the subaperture testing. As all the experiments are conducted with a 5-dof adjustment platform with big adjustment errors, it proves that using the above mentioned algorithm, the subaperture stitching can be easily performed without a precise positioning system. In addition, with the algorithm, we accomplish the coordinate unification between the testing and processing that makes it possible to guide the processing by the stitching result.
应用迭代三角测量拼接算法，我们通过测试一个直径120毫米的平面镜、一个直径1450毫米的离轴抛物面镜和一个凸双曲面镜进行了实验演示。通过将拼接结果与自检子孔径进行比较，结果表明重建结果与子孔径测试结果一致。由于所有实验都是在具有较大调整误差的五自由度调整平台上进行的，这证明使用上述算法，无需精确的定位系统即可轻松进行子孔径拼接。此外，借助该算法，我们实现了测试与加工之间的坐标统一，从而能够根据拼接结果指导加工。
