Near-infrared image colorization method for edge device

The invention discloses a near-infrared image colorization method for edge equipment. The near-infrared image colorization method comprises the following steps that a near-infrared image feature map sequentially passes through generator network encoder modules Enc1, Enc2, Enc3 and Enc4, and corresponding output feature maps are output; the input feature patterns of the generator network decoder modules Dec3, Dec2 and Dec1 are formed by splicing the feature patterns after up-sampling processing in the previous stage and the output feature patterns of the corresponding encoder modules, and then the corresponding feature patterns are output through the generator network decoder modules Dec3, Dec2 and Dec1; and carrying out feature map fusion on the output feature maps of the Enc4, the Dec3, the Dec2 and the Dec1, and finally generating a feature map of a colorization result. The near-infrared image colorization method solves the problems that an existing near-infrared image colorization method needs a large amou
