Problems solved by technology

However, in actual measurement, the visible light band is generally sampled at intervals of 1nm / 5nm / 10nm, etc. If sampling at 5nm intervals is used, the visible light band is 400nm from 380nm-780nm in total. In this way, if all band sensors are used, 81 detectors are required. Even with 20nm interval sampling, 21 band sensors are required, so not only the cost is huge, but also the installation of dozens of detectors is very problematic

Abstract

The invention provides a novel cotton colorimeter, its sensor is composed of a Y(lamda) sensor and a Z(lamda) sensor groups that including 5 to 10 wave band sensors. The 5 to 10 wave band sensors are respectively sensors of different wave bands in the blue light wavelength range, and the values of the different wave bands in the blue light wavelength range are divided into a first wavelength range, a second wavelength, a third wavelength range, the invention uses at least five Z(lamda) sensors composed of wavelength sensors and one Y(lamda) to reach a measuring result with accuracy of delta Rd <=+-1(%), deltab<=+-0.5(%), which not only assuring the accuracy, but also reducing cost of instrument and cost of measuring.

Description

technical field [0001] The invention relates to a cotton color meter and a cotton color measuring method. Background technique [0002] Cotton cultivation in my country has a history of about 2,000 years. At present, the cotton quality inspection is generally divided into different grades according to the maturity degree, color characteristics, ginning quality and other conditions of cotton. Among them, the color test of cotton is an important basis for cotton classification. The early cotton color inspection was mainly determined by the eyes of graders, but the subjective measurement of human eyes contains human factors, and it can only roughly evaluate the color difference of cotton, but cannot make an absolute measurement of color. From the perspective of colorimetry, the color evaluation of any object is related to its lighting source. Therefore, the colorimetric measuring instrument used for cotton color measurement must integrate the spectral luminous efficiency char...
