共線條件에 의한 地上收斂寫眞의 正確度解析에 관한 硏究

A Study on the Analysis of Accuracy for Terrestrial Convergent Photos by Collinearity Condition

本 硏究는 直線 및 圓弧上에서 얻은 地上収斂寫眞의 space resection, space intersection을 共線條件에 의해 解析함으로써 그의 特性을 究明하고 最適収斂角의 범위를 提示하는 데 目的이 있다.

This study analyzes space resection and space intersection for terrestrial convergent photos taken on the straight line and the circular line by collinearity condition. The purpose is to investigate the properties of convergent case, and to suggest the optimum angle of convergence. Accuracies at convergent angles less than 20° are lower than those in normal photos, but by changing from 20° to 90° the accuracy is improving with the highest at 90° convergence. Also, convergent photos on circular line is far higher than those on straight line in accuracies of results, therefore it is expected to apply this results effectively for precise analysis of various facilities.
