We have developed a new ortho-rectification method called “ortho mosaic” that generates a sharper ortho image using multi-scan images of EO satellite. Due to relatively large parallax among multi-scan images caused by satellite's attitude, a reconstruction-based super resolution algorithm is not applicable. Instead, the “ortho mosaic” selects an image that gives the highest sharpness for each area, and generates an ortho image in a mosaic-like manner. Our experimental result shows that “ortho mosaic” outperforms over a typical ortho-rectification using a single image regarding image sharpness.
