Graduations manufactured with the SUPRADUR process act optically like three-dimensional phase gratings, but they have a planar structure and are therefore particularly insensitive to contamination.

毕业与制造过程中的行为SUPRADUR像光学三维相位光栅，但他们有一个平面结构，因此特别不敏感的污染。

Experiments are performed to show that the proposed algorithm can locate corners accurately, is rotationally invariant, has scale invariant property and is insensitive to noise contamination.

实验结果证实了该算法角点定位的准确性、旋转不变性，具有一定的尺度不变性和抗噪声能力。
