Abstract

The invention provides a pointer type instrument reading identification method and device, by which the instrument is effectively prevented from being damaged; more and more complex scale lines are identified, the error of instrument scale identification is eliminated, the identification precision of the pointer type instrument reading is greatly improved, meanwhile, the Hough transformation, a least square method and other algorithms are not used, the use of complex algorithms is avoided, the operation speed is greatly increased, and the better real-time performance is guaranteed.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a method for recognizing readings of pointer meters. Background technique [0002] As a relatively traditional measuring instrument, the pointer instrument is widely used in scientific experiments, industrial production and other fields due to its simple structure, convenient maintenance, low price, high reliability, strong adaptability, and small environmental impact. It still has an irreplaceable position after the appearance of digital instruments. [0003] At present, most of the indications of pointer instruments are obtained by manually observing the pointer readings on the instrument dial. This method is greatly affected by subjective factors and objective conditions. For example, different observation angles, observation distances, and judgment and estimation capabilities of readers will cause large errors in readings, and the reliability is not high. Once real-t...
