近景摄影测量像控点坐标获取的新方法

摘要

In this article ,a new target on the basis of the original one is designed to sur-vey the coordinate of the target center accurately and rapidly w hich acted as photo control points of close-range photogrammetry .Different kinds of surveying method for various ob-servation distances are introduced in this article ,and the relevant computational methods to compute the coordinate of the target center are also provided .After the accuracy of the cal-culating methods being calculated and analyzed ,two surveying methods with corresponding calculate methods are determined at last .T he surveying accuracy and efficiency of the target center’s coordinate is improved by this new target .%在原有近景摄影测量标靶的基础上，设计了一种新型标靶，用于精确、快速地测量标靶中心坐标，作为近景摄影测量的像控点。该新型标靶针对不同长度的观测距离有相适应的观测方法，本文针对不同的观测方法，分别给出了相应的靶心坐标计算方法，并进行了计算精度的对比分析。确定了两种靶心坐标观测方法和与之相适应的靶心坐标计算方法。与原有的靶心坐标测量方法对比，通过使用新型标靶，提高了获取近景摄影测量靶心坐标的效率和精度。
