This paper presents the results of a practical automatic three-dimensional matching project. It consists of two major parts.
The first part is related to the automatic three-dimensional matching project implemented for a digital close range photography test. The components of this test include two CCD cameras with a resolution of 758×580 Pixels set on a 70cm horizontal bar. These cameras are set at a distance of 3m from the object. A new type of signs which have been devised for identification and extraction of control points from photos have been set on an around the area under examination. A computer program was prepared for automatic identification and extraction of these signs by computer.
The program is able to create a three-dimensional spatial shape (a model) from two images with cover automatically. The practical method is based on the Bundle Block Adjustment.
The second test was carried out with the aim of working with digitalized aerial photos. These signs have been set in place of fiducial marks and at ground control points. This test is somehow different from the first test, because in this case the program must first carry out the internal justification and then the relative and absolute adjustments.
In general, this paper discusses a method which is used for achievement of automatic matching in digital photography.
