Improved UAV image mosaic method
Yiping Zhang · Computer Engineering and Applications Journal · 2011
SIFT algorithm is widely used in Unmanned Aerial Vehicle(UAV) image sequence mosaic.Since the traditional SIFT-based image mosaic takes highly computational cost,through analyzing the homography relations between the original images and the down-sampling images,a method for improving mosaic speed is proposed.The role of various parameters of SIFT feature detector is dealt with,and a mechanism of mosaic parameter selection is derived.Experimental results show that the mosaic method can select suitable mosaic parameter value according to the image characteristics and applications,perform fast and steady.
