| 摘 要： | 结合工程应用实践,分析了平移变换、相似变换、仿射变换等实现影像平面坐标转换的方法,三种方法各有适应范围与优缺点,实际应用中选择哪种变换方法,主要以最大限度保证影像光谱信息不受损失,其次以精度损失最小的平面坐标转换模型为标准,就能得到满足应用需要的成果。

| Abstract: | Based on practice, the methods of moving translation, seminar translation, affine translation for Image coordinate system translation are been analyzed. Which method will be selected, the first should be considered is minimizing the deduce of image spectral information, the second factor is minimizing the deduce of image horizontal precision, then we can own the products we aspired. |
