Research and implementation on geometric rectification of areo images

Aero reconnaissance plays an important role in the military affairs. This paper studies geometric rectification of aero images. Polynomial and bilinear interpolation are used to process geometric rectification of images, which are taken by aerial camera in flight experimentation. The GCPs are got by GPS in the local. The result shows that the orthophoto image, which is made in the experimentation, can be used in the fusion, registration and target recognition.
