线阵CCD立靶坐标测量精度分析

PRECISION ANALYSIS OF COORDINATE MEASUREMENT

简述了线阵 CCD 像机对空间点目标进行交汇测量的原理,推导了坐标计算公式及其精度计算公式,给出了整个靶面精度分布.数值计算结果表明:在所有影响坐标测量精度因素中最主要的是 CCD 的像机测角误差.

This paper introduces the principle of measuring the coordinate of a space point from the way of crossing measurement by using two line array CCD cameras,deduces the formula of the coordinate of the space point and its measuring precision,and gives the measuring precision distribution on the whole target.Calculating results show that the chiefest factor of all affecting the precision is the measuring angle error of CCD cameras.
