摘要
航摄像片框标的识别与定位是进行数字影像内定向的重要环节,框标定位的速度及精度直接影响着航测数字化生产的效率和质量。文中研究了利用Hough变换,进行航摄像片"米"字形框标自动识别与定位的算法。实验证明,该方法十分有效。
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.
