Abstract:
In this study, we will evaluate both of the effect of the number of control points and the effect of the ratio of the base line distance (B) over the object distance (D) [(B/D) ratio] on the accuracy obtained from the ground coordinates using non-metric photographs for documenting historical buildings. A wall of Moid Shikh historical mosque located in Ghoria, beside Bab Ziwala, Cairo, Egypt, is employed as a test object. The data acquisition and the analysis of the results for number of control points and the ratio of the base distance (B) to the object distance (D) [(B/D) ratio] are presented in this study. The results for evaluated the effect of the number of control points on the accuracy obtained from non-metric photographs for documenting historical buildings show, when the number of control points increasing, the accuracy is increasing. Also, the effect of [(B/D) ratio] on the accuracy shows the relations Y, Z and R direction are directly proportionally in the range of 0.5≤(B/D) ratio≤1.0, while the relations are inversely proportionally in the range of 1.0≤(B/D) ratio≤1.5. Only the relation in X-direction is not matched with the other relations.
