Problems solved by technology

When using the Lovibond colorimeter to measure color, there are certain requirements for the user's vision, such as color blindness and color weakness cannot perform this work. In addition, eye fatigue will also cause measurement errors
But there is no application of spectrometer color measurement technology to replace (visual) Lovibond colorimeter spectrometer Lovibond color scale colorimeter

Abstract

The invention discloses a Lovibond chroma scale spectrograph color measuring device and method. The advantage that a CCD spectrograph can well measure spectral characteristics is used, and a Lovibond chroma scale color measuring technical scheme which can guarantee the accurate and uniform nationwide quantity value is provided. On one hand, the relative spectral power of a standard light source is stored in a computer; on the other hand, all Lovibond entitative color pieces can be changed to digital Lovibond standard color pieces, and a standard spectral characteristic transmittance function is formed regularly and stored in the computer; then, combination matching is conducted on the digital Lovibond standard color pieces through the method of successive approximation, a combination matching result which is uniform with the color of a sample is obtained and the Lovibond chroma scale value formed by combining the digital Lovibond standard color pieces is the color value of the sample to be measured. The color measuring device and method have the advantages of being high in color measuring accuracy, capable of avoiding color measuring errors caused by processing errors of the entitative color pieces and also capable of avoiding measuring errors caused by human eye visual fatigue, having no color vision requirements for detection personnel and the like.

Description

technical field [0001] The invention relates to a color measuring device of a Lovibond color scale spectrometer and a color measuring method thereof. Background technique [0002] Due to the differences in the needs in the field of colorimetry, the diversification of the development of color measurement technology is an inevitable result, but most of them are based on the methods specified by the existing national standards and international standards, and have the characteristics of strong specificity. Due to the rapid development of science and technology, small spectrometers developed from the application of CCD technology have been widely used in various fields that require spectral measurement, and are also used in the field of color measurement. [0003] The Lovibond colorimeter is a set of color chips composed of a set of red, yellow and green primary color chips and a set of gray color chips. The color measurement method is to observe the sample field of view and the...
