空白真正射纠正影像的生成

Blank Generation of True Orthorectified Image

空白真正射纠正影像的生成是基于DSM制作真正射影像的最重要的一部分,是进行正射纠正读取原始图像数据进行内定向和相对定向后首先要解决的问题。本文以VC++中MFC为开发平台利用仿射变换,实现影像内定向;然后利用共线方程,解决像素坐标、像平面坐标和地面点坐标之间的相互转化,为利用数字微分纠正技术进行影像的真正射纠正的灰度赋值做好了准备。

Blank generation of true orthorectified image is an important part of true orthophoto which is based on DSM,and it is the first problem after the original orientation and relative orientation through orthorectified image data reading the original image.We take the VC＋＋MFC as a development platform in the affine transformation to achieve original orientation.We use a total of line equation to achieve transformation among pixel coordinates and photo coordinates and the ground point coordinates,which is ready for the assignment of orthorectified assignment of gray using differential correction technique.
