摘要
Abstract
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.关键词
