Intelligent character recognition method, system and device in electric power complex scene

The invention relates to the field of character recognition, in particular to an intelligent character recognition method, system and device in a power complex scene, and the method comprises the steps: obtaining a to-be-analyzed image frequency domain graph through an initial frame extraction test; performing frequency domain mask processing on the to-be-analyzed image frequency domain image to obtain test fuzzy grey-scale images with different fuzzy degrees, and comparing the test fuzzy grey-scale images with different fuzzy degrees with the initial frame extraction test image to obtain font detail loss degrees of the test fuzzy grey-scale images under different fuzzy degrees; obtaining different character structures under the same fuzzy degree and structure detail loss degrees corresponding to the different character structures under the different fuzzy degrees, and obtaining character structure adjustment weights of character recognition of the electrical equipment under the complex power scene under the
