The invention provides a cold-rolled steel sheet defect image data processing method, and relates to the field of image enhancement. The invention provides a cold-rolled steel sheet defect image data processing flow. Comprising the steps of cold-rolled steel sheet defect image collection, global attention GSA construction, feature processing block FHB construction, feature conversion module FFT construction, bottleneck processing block BNB construction, lower transposition module DT construction, upper transposition module UT construction, cold-rolled steel sheet defect image enhancement module construction and cold-rolled steel sheet defect image enhancement. Meanwhile, a cold-rolled steel sheet defect image enhancement module is provided, the whole module follows a Unet architecture, a feature processing block FHB can capture pixels of a long-distance spatial position, a feature conversion module FFT can convert an image into primary features, a bottleneck processing block BNB can improve the feature extrac
