摘要: 介绍了一种精密测量相机畸变和主距的测量及数据处理方法。介绍了测量原理和仪器装置,分析了测量精度,同时给出了一种通过用正交多项式对常用的最小二乘法拟合法的改进来增加畸变曲线拟合精度的算法。本文所测量的对象是某“高空CCD立靶”测量系统。

关键词: 畸变 , 主距 , 精度

Abstract: Gives a method for the measurement of distortion and principal distance, as well as for data processing in cameras used in precision measurement. Principles of measurement and the arrangements used are given, and the precision attainable analyzed. A method of calculation is given in which orthogonal polynomial method is applied to improve on the least square method so as to increase the accuracy of resulting distortion curve.

Key words: distortion , principal distance , accuracy
