Abstract

Monuments and historical sites usually exposed to changes in color, material and shape due to several environmental and human factors. Therefore, continuous repair and maintenance for these valuable monuments and sites are usually needed. Preparing permanent precise records and documents for these monuments is the optimum way for their preservation. The purpose of this paper is to study, and assess the factors affecting the accuracy when using Close Range Photogrammetry (CRP) technique to reconstruct 3D objects. The façade of Coptic Museum and the AMR IBN AL-AAS Gate were chosen in this study. The results indicated that flatbed scanner with metric camera was acceptable in such cases when the photographed facades have no coarse details. whereas, nonmetric camera cannot be used in precise measurement. Also, it was concluded that using photogrammetry scanner with metric camera in close-range photogrammetry technique were acceptable for precise 3D restoration applications.
