The invention discloses a method for automatically inputting electrical equipment nondestructive testing data based on an optical character recognition (OCR) technology. A field data recording list special for field nondestructive testing of an electrical equipment X ray digital imaging system, and a system for automatically inputting the electrical equipment nondestructive testing data based on the OCR technology are involved; and the field data recording list specially used for the system for automatically inputting the electrical equipment nondestructive testing data based on the OCR technology. The method has the advantages that: a large amount of field data can be automatically input into an original X ray digital image, and high efficiency and accuracy are achieved; and the record and storage of the field data are specified.
