摘要
Abstract
In order to develop a pH test paper detection method with higher efficiency and accuracy,an automatic pH value detection technology is presented based on the digital image processing technology.Firstly,the target area was selected from the pH test paper image of the unknown solution obtained by camera,and the noise reduced image was collected with the method of median and mean filtering.Secondly,the RGB color model of the image was converted to the HSV color model,and the relationship between the pH value and H component was found out according to the principle of different colors of the pH test paper corresponding to different H components.Finally,the value of the H component was obtained based on the pH test paper image of unknown solution,which could be used to determine the pH value.This method was tested in many images of pH test paper for different solutions.The experimental results show that this method,compared with the method of artificial vision and electrode,is of sound stability and high efficiency.关键词
