摘要
提出了一种新的全场高度映射方法，利用激光片光产生的莫尔条纹的性质，拟合出两个映射曲面。通过这两个曲面方程，可同时直接得出ＣＣＤ探测器表面任意一点在实际世界坐标系中对应的高度和一维横向坐标。
A new mapping algorithm between real world coordinate and CCD coordinate for 3 D sensing with laser sheet triangulation is presented and verified by experiment. Two mapping curved planes are generated with the characteristic of moire patters that is formed by laser sheet. We can get the real world coordinate z and y of every point in the surface of CCD camera simultaneously through these two mapping curve plane.
