Abstract: In the emergency rescue, it is necessary to quickly understand the actual situation of the search and rescue region. A fast approach for ortho image generation of the search and rescue region based on unmanned aerial vehicle system was put forward, through image sequential adjustment, ortho rectification based on CPU-GPU, and fast image mosaic, ortho image of the search and rescue region without-obvious seam-line was obtained.

Key words: unmanned aerial vehicle, sequential adjustment, ortho rectification, image mosaic
