The Integration between CAD and Digital Closerange Photogrammetriy for Accuracy Studies

Mostafa Abdel-BaryEBRAHIM, Farrag Ali FARRAG

Accuracy studies in plane (2D) or in space (3D) have been carried out in digital close range photogrammetry in different ways and by different methods. Basically, the accuracy studies in digital close range photogrammetry depend on the field measurements of the object. CAD environment has a wide incorporation in digital close range photogrammetric works. These fieldwork measurements have a certain accuracy, which depends on the measuring tools and the used method. This accuracy can affect the accuracy of the results obtained by digital close range photogrammetry. Such effect can be easily obtained theoretically, but it is hard to be obtained practically. To avoid the effect of the field measurement accuracy on the digital close range photogrammetric accuracy, a new technique is applied in this study to obtain a test field that has a very accurate dimension. In the same time, by using this technique the camera orientation elements can be fixed with a certain values, which have free errors. This paper will discuss the details of this new technique based on CAD (3D Studio software) as an excellent environment for accuracy studies in digital close range photogrammetry. The effect of camera configuration on the accuracy of close range photogrammetry is also analysed.
