摘要
为了考察航测双片立体模型包括数字影像模型的测图或测点的精度,本文以连续相对定向为基础,采用空间前方交会方法,推导了测点中误差计算公式,进而引进了航摄精度因子的概念。
In order to study the accuracy of topographic points on double photo stereo-pair model, including digital image stereo model, the formula of root mean square error of topographic points is derived based on the continuously relative orientation and the space intersection method. It implements the concept of accuracy factor.
