Three-dimensional measurement can be simplified to planar measurement through a series of steps : firstly , acquire the image by CCD photoelectronic sensors ; then recognize the centre of a circle by image processing and calculate the space included angle for the relative position of hole series .

用CCD光电传感器获取图像，通过图像识别确定圆心坐标，按几何关系计算出孔系空间夹角，可将三维测量简化为二维测量。
