摘要
从实际需要出发,根据最小区域原理,提出了一种快速评定直线度误差的数学模型。该方法是通过某一理想直线将被测实际线分成上、下两部分,即可精确找出符合最小条件的三个最优点。
For the practical purpose, presents a kind of fast mathematical model derived from principle of minimum zone to evaluate the linearity error. By means of a true line, the measured actual curve is divided into two areas. One of the areas is above the true line, and the other is below. So the optimum points which are in ac-cord with minimum condition can be obtained accurately.
