Real-time stitching is a research focus of UAV area.The speed and accuracy of stitching algorithm are both important for commanders to make right decisions in battlefield.In this paper, a real-time UAV aerial image stitching algorithm based on predicted region matching is proposed.A new matching strategy is applied to the feature matching step.The transformation matrix will be calculated by the matches between features in current image and features in a predicted region.Experimental results show that, comparing with traditional method, the new algorithm can reduce much stitching errors while keeping the process time almost the same.
