Mathematical Morphology Algorithm for Recognizing and Positioning of Cross-type Fiducial and Its Fast Realization

试验的特点是：1、计算机自动搜索框标进行内定向；

The main characteristics of this experiment are : 1 , the fiducial marks are searched automatically by the computer for the inner orientation ;

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。

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 .

数码相机属于非测量相机，它没有框标及定向设备，不能得到摄影瞬间的内、外方位元素的初始值。

Digital camera belongs to non-metric camera , which has no fiducial marks and orientation equipment . Thus it is impossible to obtain the initial values of the interior and exterior orientation elements at the moment of shoot .
