Offshore wind turbine blade corrosion identification method based on Transform

The invention discloses an offshore wind turbine blade corrosion identification method based on Transform, and the method comprises the steps: constructing a four-stage symmetric coding-decoding structure through the Transform, employing a nonlinear inactive network in the Transform to reduce the calculation complexity, obtaining the multi-scale information of blade surface damage through a mixed scale feed-forward network, and improving the detection effect. According to the method, the defect of a traditional CNN in the aspect of long-distance related information representation is made up, the structure of the Transform is simplified, and the problem that the calculation complexity of the traditional Transform is squarely increased along with the improvement of the spatial resolution is solved; and secondly, while the module structure is simplified, multi-scale information is utilized, so that the network not only contains global overall information, but also contains local detail information, the corrosion
