Intelligent image identification method of device nameplate and energy efficiency label

Abstract

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.

Description

technical field [0001] The invention relates to an image recognition method, which belongs to the technical field of intelligent image recognition, in particular to an intelligent image recognition method for equipment nameplates and energy efficiency labels, which is mainly used to identify Take photos of the nameplates and energy efficiency labels of energy-consuming equipment or products, obtain the technical parameters of the equipment or products through image recognition, and identify whether the energy consumption of the equipment or products exceeds the national standard based on the technical parameters. Background technique [0002] For a long time, the state has made specific regulations on the energy consumption quotas of different energy-consuming equipment or products, and issued a number of standards. Reviewing the energy consumption quotas of these equipment or products is an important part of energy-saving supervision and energy-saving management. At present...

Problems solved by technology

At present, due to the informatization construction of energy-saving supervision and energy-saving auditing in my country is still in its infancy, and there is no technical tool to directly identify information such as nameplates and energy-efficiency labels of energy-consuming equipment in the world, all on-site business of energy-saving supervision and energy-saving auditing can only The method of manual checking and recording is used to identify and identify energy-consuming equipment one by one. If there is a phenomenon such as omission and misrecording, it is necessary to go to the site again for manual investigation. The large number of energy-consuming equipment not only consumes a lot of manpower , material and financial resources, and the cycle is long, the efficiency is low, and human factors are likely to affect the accuracy and objectivity of the results, which seriously restricts the promotion and implementation of energy conservation monitoring and energy conservation management tasks
