The mathematical model for the coordinates of the probe tip center under the light pen coordinate system has been built.

建立了测头中心在光笔坐标系中的坐标值的估算模型。

When measuring, the probe of the light pen contacts the measured point, the CCD camera takes the image of LEDs on the light pen, and the 3D coordinates of the measured point are obtained by computing the coordinates of LEDs in the image plane.

测量时，使笔尖测头接触被测物体表面，摄像机摄取笔体上3个发光二极管的像，由3个发光二极管的像面坐标就可计算出被测点的三维坐标。
