| Abstract: | The recognition and position of aerial photo fiducial marks are of great importance in interior orientation, and the speed and accuracy of calculation affect the efficiency and qualification of digital photogrammetry production directly. In this paper, an algorithm and test results are presented of Hough transform to accurately position the center location of star-shaped fiducial marks. |
