The UAV Video Image Stitching Based On Improved Moravec Corner Matching Method

As a kind of new image sources, UAV (Unmanned Aerial Vehicle) Video is used more and more widely. In this paper, the image matching based on corner feature is used to achieve image stitching. Moravec operator is a kind of simple and efficient method for corner feature extraction. In this paper we do special treatment on it, which covers the distributed conjugate points over full frame with virtual grid to improve the precision of corner feature extraction. In the process of image mosaic, we use fade in/out method to achieve video image seamless stitching. KeywordsUAV Video; Moravec; Feature Extraction; Image Stitching
