Abstract

The invention provides a pointer type instrument information identification method and device and electronic equipment. For any to-be-identified pointer instrument which needs to be read, the electronic equipment acquires an instrument image of the pointer type instrument; feature extraction is carried out to obtain the position information of a plurality of specific key points including the instrument range of the pointer instrument to be identified, an instrument range starting point, an instrument range ending point, an instrument pointer fixing point and an instrument pointer index point;then, no matter what instrument type the pointer instrument to be identified is, the current reading of the pointer instrument to be identified can be quickly and accurately calculated by directly utilizing the respective position information of the plurality of key points and the instrument range, a specific identification algorithm does not need to be deployed in advance, the method can be suitable for various pointer instruments, and the identification efficiency is improved.

Description

technical field [0001] The present application mainly relates to the technical field of image processing, and more specifically relates to a pointer instrument information identification method, device and electronic equipment. Background technique [0002] As an important tool for data monitoring and data collection, instruments play a huge role in production and life, such as water meters, electricity meters, gas meters commonly used in people's lives, and various types of pressure gauges commonly used in industry. meter. [0003] In practical applications, for the data identification of different types of pointer instruments, the readings are usually identified by using information such as the unique color or shape of the corresponding pointer instruments, which requires pre-configuration of different identification for different types of pointer instruments Algorithm, the process is cumbersome and the recognition efficiency is low. Contents of the invention [0004] ...
