The invention discloses a method for modeling image characteristic data of power equipment. The method comprises the following step: after the pictures of the power equipment collected in the regularpatrol process of the intelligent equipment of AR wearing equipment or a patrol robot are recognized, carrying out definition specification of the image characteristic data of the power equipment withuniform appearance by adopting a D language to form structured table data, wherein the power equipment comprises primary field equipment, secondary field equipment and metering field equipment. According to the method, the collected image characteristics of the power equipment are subjected to unified and standardized data modeling, so that on the basis for forming large data of an image libraryof the power equipment, the fault statistics of the power equipment are facilitated, the intelligent identification accuracy of the power equipment is improved, the operation and maintenance effects of the power equipment are greatly improved, the safe and stable operation of a power system is further guaranteed, the structured data is converted, the image data is greatly compressed, the image data is conveniently stored in a database, and mining analysis of large data in later period is facilitated.
