一、前言物体表面形状的测量方法可分为两类。一类是从基本座标系统测量物体上几个取样点的座标,而求形状的方法。还有一类是用任意二维法,根据测得的图形求从某方向看物体表面形状的方法。前者与后者相比,在 First, the preface Measurement method of the surface shape of objects can be divided into two categories. One is from the basic coordinate system to measure the coordinates of several sampling points, and seek the shape of the method. Another is the use of any two-dimensional method, according to the measured figure seeking a direction from a certain direction to see the surface shape of the object. The former is compared with the latter
