Remote sensing image extrapolation method for camouflage evaluation

The invention provides a camouflage evaluation-oriented remote sensing image extrapolation method, and belongs to the field of remote sensing image generation. The method comprises the following steps: firstly, constructing a two-stage image extrapolation frame; secondly, text encoding optimization is carried out, and text encoder parameters are updated; then constructing a remote sensing image extrapolation data set oriented to camouflage evaluation, forming an original remote sensing image-canvas-cut remote sensing image-prompt text data pair, and introducing human preference to the data set; carrying out two-stage image extrapolation training; and finally, selecting an original remote sensing image needing extrapolation according to application requirements, setting an extrapolation canvas, compiling a sentence of natural language description, and generating an extrapolation remote sensing image by taking the natural language description as a prompt of image extrapolation.
