Problems solved by technology

As we all know, Chinese medicine decoction pieces have different shapes, and most of the surfaces are uneven. It is impossible to meet the requirement that there should be no gap between the colorimeter and the measured object.
Therefore, conventional colorimeters cannot be used to measure the color of the appearance of Chinese herbal pieces, and it is necessary to develop a new method for detecting the appearance of Chinese herbal pieces.

Abstract

The invention discloses a method for detecting the color of the Chinese herbal tablet, comprising the followings steps: converting the information on the color of the contrasted Chinese herbal tablet and the Chinese herbal tablet to be detected into the CIELab value, and calculating the difference between the color of the contrasted Chinese herbal tablet and the color of the Chinese herbal tablet to be detected according to the CIEDE2000 color difference calculation formula. The method can be used for quantitatively describing the color of the Chinese herbal tablet and the difference between the color of the contrasted Chinese herbal tablet and the color of the Chinese herbal tablet to be detected so as to change the status quo of the traditional method for judging the color of the Chinese herbal tablet fully by the subjective feeling and experience and better ensure the quality of the Chinese herbal tablet. The CIELab value is obtained in such a way of putting the contrasted Chinese herbal tablet and the Chinese herbal tablet to be detected on the white background, taking a picture for the contrasted Chinese herbal tablet by using a CCD camera when a certain condition being met, collecting the picture for the contrasted Chinese herbal tablet in a computer and converting the information on the color of the contrasted Chinese herbal tablet in the picture into the CIELab value.
