摘要
研究了机载航空图像的几何校正.利用某新型军用侦察机试飞所获取的图像、定位和飞行姿态等数据,将三维投影变换引入几何校正模型中,推导出了对于同一地物在不同航片上的图像坐标变换关系,实现了图像的自动校正.通过对某地区实验飞行获取的5条航带图像进行几何校正和多航带镶嵌处理,效果理想.
Aero reconnaissance plays an important role in the military affairs. The geometric rectification of airborne image is studied in this paper. With the images,position and attitude acquired by some new military scout,the transformation of three dimension projection is applied to the model of geometric rectification,the transform of image coordinate relation can be implemented in different aerial images about the same object and the image automatic rectification is realized. The geometric rectification and the mosaic processing of five lines of images in test flight in some areas have yielded an ideal effect.
