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.]]>Atkinson, K.B.,2001Jechev, D.,2004Karara, H.M. and Y.I. Abdel-Aziz,1974Mofitt, F.H. and E.M. Mikhail,1980Nutto, M. and K. Ringle,2001Wolf, P.R. and B.A. Dewitt,2000
