Method for scanning images from the air

摘要

Appropriate to the height and speed of the scanner above the surface scanned an overscan factor is determined. A first image (Bild0) is then positioned centrally. For subsequent images (Bildi), etc. corresponding to their image offset an offset vector (dx,dy) is calculated and with the aid of these the images are lined up above one another. In the areas of image overlap determined by the overlap factor the image content is averaged
