Problems solved by technology

[0003] At present, the instruments used by the drilling team to measure parameters such as drilling fluid friction, mud pump pressure, standpipe pressure, and drilling pressure at the well site are all analog pointer instruments, which require operators to read and record the current values ​​regularly. On the one hand, it is easy to Make mistakes and generate reading errors; on the other hand, it needs to consume a lot of manpower and material resources, the reading efficiency is low, and the misjudgment rate is hig

Abstract

The invention discloses an automatic instrument identification method and system, and belongs to the technical field of image processing, and the method comprises the steps of collecting an image of an instrument; carrying out distortion correction on the image; acquiring the circle center of a dial plate in the image; obtaining a pointer position based on a Hough transform, circumferential template matching or radius gray scale matching method; positioning the scale marks of the dial plate to obtain the positions of the scale marks; obtaining the measuring range of the instrument; and calculating instrument readings according to the pointer, the circle center, the measuring range and the scale marks. Through the image processing technology of machine vision, the circle center, the pointer, the measuring range and the scale marks of the instrument are recognized, and the count of the instrument is calculated to replace manual counting, so that the recognition efficiency and accuracy are improved, and manpower and material resources are saved; and a reading error caused by an instrument template matching error is avoided.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for automatic instrument identification. Background technique [0002] Mechanical instruments, such as pointer instruments, are widely used in various processing fields such as petroleum and coal. They have the advantages of strong anti-interference, dust-proof, waterproof, and long life, especially for fire-proof and explosion-proof occasions and harsh environments, such as electric power , petroleum, chemical industry, etc., the pointer instrument is still the first choice. [0003] At present, the instruments used by the drilling team to measure parameters such as drilling fluid friction, mud pump pressure, standpipe pressure, and drilling pressure at the well site are all analog pointer instruments, which require operators to read and record the current values ​​regularly. On the one hand, it is easy to Make mistakes and generate reading errors; ...
