【摘要】：結(jié)合平面曲線輪廓度誤差評(píng)定的最小條件原則及雙曲線的幾何特性,提出了基于幾何遍歷搜索的平面任意位置雙曲線輪廓度誤差評(píng)定算法。首先,依據(jù)最小二乘法得到測量數(shù)據(jù)的最小二乘雙曲線方程和兩個(gè)焦點(diǎn)坐標(biāo)。其次,在兩焦點(diǎn)周圍按一定規(guī)則布置一系列的輔助點(diǎn)并構(gòu)造出一系列輔助雙曲線。然后,計(jì)算出所有測量點(diǎn)到輔助雙曲線距離的極差值。經(jīng)過比較和判斷,最終實(shí)現(xiàn)雙曲線輪廓度的最小區(qū)域評(píng)定。
[Abstract]:Based on the minimum condition of contour error evaluation of plane curve and the geometric characteristics of hyperbolic curve, an algorithm for evaluating the contour error of hyperbolic curve at any position is proposed based on geometric ergodic search. First, the least square hyperbolic equation and two focal coordinates of the measured data are obtained by the least square method. Secondly, a series of auxiliary points are arranged around the two focal points according to certain rules and a series of auxiliary hyperbolic curves are constructed. Then, the extreme difference between all the measured points and the auxiliary hyperbolic distance is calculated. Through comparison and judgment, the minimum region evaluation of hyperbolic contour is realized.
