Abstract :
Blank image for true orthorectified is the essential components for true orthophoto production, which is based on DSM (Digital Surface Model). It is the first problem to solve after the interior orientation and relative orientation through orthograph rectification reading the original image data. VC++/MFC are used as a development platform to make affine transformation, and then achieve interior orientation. And also linear equation and collinearity equation are used to implement transformation among pixel coordinates and photo coordinates and the ground point coordinates, which is ready for true orthograph rectification assignment of gray using differential correction techniques.
