This paper describes an effective mosaic algorithm for UAV aerial images under the circumstances that the vehicle is executing a multiple-strips flying task. The proposed algorithm relies on two parts. One part is the basic image mosaic method which has three steps: firstly, an PCA-GSIFT is constructed to get the key points of the two images to be stitched, secondly, to get the matched pairs, an innovated matched pairs filter is presented, thirdly, to complete the registration and fusion, a weighted average method is implemented. And the other part of the new algorithm is the multiple-strips images mosaic strategy based on a global modulation strategy. Experimental results show that the approach has strong stabilization as well as high efficiency and performs excellent in multiple-stips flying UAV’s panorama generating .
