Infrared image colorization method and system based on reference image

The invention belongs to the technical field of image processing, and particularly relates to an infrared image colorization method and system based on a reference image, and the method comprises the specific steps: 1, constructing a network model: constructing a generative adversarial network comprising a generator and a discriminator; 2, preparing a data set: preprocessing the first infrared image data set and the second infrared image data set, adjusting the size of each image in the data set, and fixing the size of the input image; and step 3, training a network model: training an infrared image colorization model, and inputting the first infrared image data set into the constructed network model for training. According to the method, the reasonable corresponding relation between the input image and the reference image can be accurately established, so that the color of the reference image is faithfully transmitted to the input infrared image, and a high-quality colorization result can be obtained.
