Considering the feature of unmanned aerial vehicle(UAV) image,an image mosaic algorithm based on local gray fitting method was developed.According to the air data of UAV,UAV image was preconditioned,which can reduce the range for searching feature point.And then,the corner feature points Abstracted were matched fast on the basis of square error of the gray value.Last,the algorithm was evaluated by speed and accurate rate.The results obtained from experiments and simulations show that this algorithm is effective and can adapt to the real-time character of UAV image stitching.The algorithm can provide some experience for the UAV image processing industrialization.
