Method for automatically stitching unmanned aerial vehicle remote sensing images based on flight control information

The invention provides a method for automatically stitching unmanned aerial vehicle remote sensing images based on flight control information, which in particular realizes automatic correction and stitching of the unmanned aerial vehicle remote sensing images according to attitude parameters acquired by a flight control system. The method comprises the following steps of: correcting aircraft yawsof the images and determining adjacency relation of the images according to the attitude parameters acquired by an unmanned aerial vehicle flight control system; extracting characteristic points fromthe corrected images, matching the characteristic points with those of adjacent images and extracting identical points; calculating a range of the output images according to an image calculating model, comparing the range with the range determined by the attitude parameters, and if the difference is within a tolerance range, considering that the number and the quality of the identical points between the adjacent images meet the stitching requirement and the images are connected; sequentially calculating connection relation among all images and solving the maximum connection component among the images; and determining a transformation parameter by performing model calculation according to the connection component and outputting a stitched image of a research region.
