An application of panoramic mosaic in UAV aerial image

Abstract

Panoramic mosaic plays an important role in the field of computer vision, robot navigation and virtual reality. This paper summarizes the specific process of panoramic stitching and proposes a coordinate transformation stitching method based on down-sampling. In order to reduce the processing time, images are compressed by down-sampling before processing, and spliced in the corresponding points of original images. Especially, the middle image is chosen as the reference image and the others are directly spliced onto it by transformation matrix. Considering the illumination of UAV aerial images, just one overlapping region of the adjacent images is remained when doing the fusion. In the experiment, images with different resolutions are tested. The results show the performance of good efficiency and little time consuming.
