Image perspective deformation processing method suitable for unmanned aerial vehicle slope inspection

The invention provides an image perspective deformation image processing method suitable for unmanned aerial vehicle side slope inspection, and the method comprises the following steps: S1, carrying out the oblique photogrammetry of a target side slope inspection region, and obtaining the slope data; s2, obtaining an unmanned aerial vehicle slope inspection image data set of the inspection target area; s3, on the basis of the slope data and the unmanned aerial vehicle slope inspection image data set, obtaining an on-site area center point corresponding to the image; s4, obtaining an overall approximate slope value through the center point of the field region corresponding to the image; and S5, based on the overall approximate gradient values of the areas corresponding to different images, performing inverse perspective change on the image data in the unmanned aerial vehicle slope inspection image data set, and approximately restoring the image data into an unmanned aerial vehicle slope inspection image data s
