Method for carrying out real-time identification by pointer-type round single instrument panel of mobile equipment

Abstract

The invention discloses a method for carrying out real-time identification by the pointer-type round single instrument panel of mobile equipment. The method comprises the following steps that: carrying out multi-dial-plate video image collection; preprocessing each frame; detecting the edge of each frame; carrying out Hough circle detection; digging out an area of interest of the dial plate; carrying out inclination correction on each dial plate; carrying out dial plate Hough straight line detection; calculating the line angle of the pointer; carrying out reading identification. By use of the method, the readings of a plurality of dial plates can be simultaneously identified, and the method has the characteristics of good robustness, real time, high efficiency, low cost and the like. Industrial production efficiency is effectively improved, industrial expenditures are reduced, and a reliable technical guarantee is provided for further industrial production.

Description

technical field [0001] The invention relates to the field of reading recognition of pointer meters, specifically a method for analyzing and processing the video of a single pointer meter panel by using a combination of image processing technology and computer vision, and then accurately identifying the readings of the pointer meter panel. Background technique [0002] The automatic reading recognition system of intelligent pointer meters is oriented to industrial pointer meters. It obtains the pictures of pointer meters through image acquisition, and uses the combination of image processing and computer vision to automatically recognize the readings of the instrument panel, so as to reduce manpower, improve the accuracy of readings and efficiency. With the rapid development of industry and the increase of data volume, higher performance and reliability are required for the pointer meter recognition system. Therefore, it is particularly important to propose a reading recognit...

Problems solved by technology

This method needs to store a large amount of image information in a relational database, and then take it out for analysis when necessary, which reduces the recognition speed to a certain extent and increases storage overhead. When the image resolution is high, the recognition speed will be greatly affected. influences

[0012] Many places in the industry often require high reading accuracy. The current pointer instrument identification method has higher and higher accuracy, but it often fails to meet the high accuracy requirements of the industry.
