Abstract: An automatic aerial remote sensing image mosaic method based on improved Harris corner detection is proposed. The horizontal and vertical gradient test is added to improve the speed; the auto-adapted threshold is added to improve the robustness. The automatic registration between images is realized. And finally image mosaic is completed with smoothing algorithm. The method implements automatically and avoids the disadvantages of traditional aerial remote sensing image mosaic method under different attribution conditions. Experimental results show that the method is stable and effective.

Key words: Harris corner detection, image registration, image composition
