The Effect of Network Geometry on Three-Dimensional Analysis in Close-Range Photogrammetry

本 硏究에서는 近接寫眞測量에 의하여 對象物의 全面에 대한 同時 精密 3次元 位置解析의 可能性을 提示하는 데 目的을 두었으며, 이를 위하여 network 의 imaging geometry, 基準點 配置 등 幾何學的 配置에 따른 正確度의 特性을 導出하였다. 또한 局部的으로 配置된 少數의 基準點으로도 所期의 正確度를 얻을 수 있었으므로 全面解析을 위한 基準點 測量의 難題를 크게 줄일 수 있을 것으로 思料된다.

The purpose of this study is to suggest possibility to analyze the three-dimensional positions of the whole surface of an object simultaneously and precisely by close-range photogrammetry. For this purpose, the geometry of network, namely imaging geometry and control configuration etc was con-sidered, and then the whole surface of the object was analyzed by bundle adjustment through forma-tion of strip and block with which cover the whole surface of the object. As a result, we were able to prove possibility of the whole surface analysis of an object and to extract characteristics of accuracies in accordance with the number and configuration of control points. Also as desirable accuracies were able to be acquired even by employing configuration of only a few control point stationed on a limited surface, it is expected that the difficulties of control surveying will be able to be reduced considerably.
