基于机器视觉的指针式仪表检测方法
Method for Testing of Pointer Instrument Based on Machine Vision
摘要
Abstract
Focusing on the problem of low efficiency ,high labor intensity ,low accuracy in traditional pointer instrument durability test .In this paper ,the machine vision and instrument detection are combined .Through the image of binarization , scale contour extraction ,fitting circle ,pointer refinement ,the solution of the linear equation of the pointer ,panoramic ex‐pansion of the scale ring and other steps ,read the dial value in real time .Experimental results show that the algorithm has the advantages of good robustness ,high accuracy ,good real‐time performance and so on .关键词
