Abstract :
This paper presents a new algorithm for image mosaic based on Harris corner detection algorithm, first use Harris operator to detect the image corner, then use the correlation feature registration to find registration pair, remove the false registration using constraint registration algorithm, find the correct registration point for image mosaic, finally use the gradual fade-out method for image fusion, image mosaic experiments show that this method can improve the accuracy and robustness of the UAV aerial image mosaic.
