| Abstract | ||
| One of the major advantages of digital photogrammetry is the potential to automate production processes efficiently, thus substantially improving the price / performance ratio for photogrammetry products. Image Processing and computer vision techniques have successfully been employed for facilitating automated procedures in digital aerial images such as interior orientation, relative orientation, point transfer in photogrammetry block triangulation, and the generation of DTMS. In this paper, the researcher presents her investigations on a digital triangulation of a block consist of two strips of eight aerial photographs. Digital imae data scanned with a resolution of 400 dpi, this gives pixel size of 63.5 μm (corresponding to 0.19m ground resolution). Each one of the eight black-and-white overlapped aerial photograph that have been used in this research has a photo scale equal approximately to 1:3000. The measurements were carried out using Pentium III personal computer with processor (CPU) 733MH, 128MB memory and 20 GB hard disk. All observations were later adjusted in dundle adjustment program (jadria) that has been written by the researcher herself. The goal of this research is building a digital aerial triangulation package to be the first trial of digital aerial triangulation in Iraqi Universities. | ||
