Intelligent image identification method of device nameplate and energy efficiency label

The invention provides an intelligent image identification method of a device nameplate and an energy efficiency label. The method is characterized in that the method includes the following steps that a character recognition feature library is built; photos of a target device nameplate or a target energy efficiency label are taken to obtain images; anti-shake noise reduction processing is connected on the images, and the unrelated pixels are removed; character features of the images are extracted, and character string information is output; according to the character string information, matching is conducted in the character recognition feature library, and the device specification type and all main technical parameters are recognized and output. After the method is implanted into a handheld terminal system, photos of the energy-consuming equipment or the nameplate and the energy efficiency label of the product are taken, the technical parameters of the equipment or the product are obtained through image recognition, automatic collection of the energy-consuming information is achieved, favorable conditions are provided for computerization audit of energy-consuming indexes and informatization storage of benchmarking, the energy-saving monitoring and energy-saving management efficiency and quality are improved, and the energy-saving monitoring level and energy-saving management level are increased.
