Abstract

In order to solve the problem of large amount of calculation of UAV image mosaic algorithm, this text put forward a kind of image mosaic algorithm based on edge extended phase correlation. First use the iterative threshold segmentation method to detect the image edge, then carry on the extended phase correlation calculation on the detected edge, thus can obtain the image translation, rotation and scale changes; using these parameters in image mosaic, last use the gradual fade-out method to realize the fusion of image mosaic. Experimental results show that this algorithm can simplify the calculation and realize the mosaic of the UAV aerial images effectively.
