Problems solved by technology

However, due to the deviation of the shooting angle, the scale instrument in the original scale instrument image obtained by the existing pointer scale instrument recognition machine is often elliptical. In this case, the pointer reading error rate calculated directly as a circle is Higher, causing a lot of inconvenience to production and life

Abstract

The invention discloses a scale identification method and device and a computer storage medium. The method comprises the steps of obtaining an original scale image; carrying out contour fitting processing on the original scale image to obtain a fitted scale image; acquiring boundary scale data corresponding to the fitting scale image according to the fitting scale image; obtaining pointer position data, corresponding to the fitting scale image, of a pointer; performing modeling processing on the fitting scale image according to the pointer position data and the boundary scale data to obtain a target scale image; and calculating a pointer reading according to the target scale image. The method effectively solves the problem that in the prior art, the error rate is high due to the fact that a pointer type scale instrument directly takes an obtained oval scale instrument as a circle to calculate the pointer reading, and the recognition accuracy of a pointer type scale instrument recognition machine on the pointer reading is effectively improved.

Description

Technical field [0001] The present invention relates to the technical field of image recognition, in particular to a scale recognition method, device and computer storage medium. Background technique [0002] In the production and life of modern society, analog scale meters are measuring instruments widely used in various fields. They are cheap, huge in quantity, and diverse in variety. Accurate reading of pointer type scale instruments plays a very important role in industrial production. [0003] In many enterprises, there are a large number of meters. If all the readings are done by people, the workload is very large, not only the cost is high, but the error rate is also high. Therefore, the prior art usually reduces the labor intensity of workers through the automatic identification technology of the pointer type scale meter, and at the same time improves the automation degree of the meter scale reading. However, due to the deviation of the shooting angle, the scale meter in ...
