Embodiment Construction

[0033] Attached below figure 1 The present invention is further described with embodiment:

[0034] Color measurement method step of the present invention is as follows:

[0035] Step 1. Build a hardware platform for cotton color measurement:

[0036] The hardware platform includes a color difference meter, a barcode scanning module and a field wireless data transmission module; the color color difference meter is bidirectionally connected with the field wireless data transmission module, and the output terminal of the barcode scanning module is connected to the input end of the field wireless data transmission module ;

[0037] Step 2. Perform stand-alone calibration on the color difference meter:

[0038] (1) Place the color difference meter vertically on the white calibration board;

[0039] (2) Start the [Calibration] function of the color difference meter and perform [Calibration];

[0040] Step 3. Test the cotton sample:

[0041] (1) Use the barcode scanning...

Abstract

The invention discloses a cotton color measuring method. The method comprises the following steps: 1, setting up a cotton color measuring hardware platform; 2, carrying out single correction of a color difference meter; 3, detecting a cotton sample; and 4, utilizing the optical switching multiple linear regression model stored in the color difference meter for calculation to obtain the cotton rating parameter indexes comprising the Rd color space and the +b color space. The method allows the cotton color to be determined through utilizing a universally accepted color measure standard by establishing the multiple linear regression model of the L*, A* and B* information quantification in an CIE three-dimensional color system based on the Rd and +b in an HVI color system, so cotton color measuring apparatuses can be substituted by testers common in the market, thereby miniaturization and portability are realized, and the determination environment is not limited to the lab environment.

Description

technical field [0001] The invention relates to a cotton color measurement method, which belongs to the field of cotton color detection. Background technique [0002] Cotton grade testing in various countries has undergone a transformation from sensory testing to instrument testing. At present, the United States has realized bag inspection, and the inspection equipment is all high-speed automatic detectors, and the inspection methods and verification and grading methods adopt the most advanced methods in the world. In 1981, some cotton farmers in the United States used large-capacity high-precision inspection instruments (HVI) to classify cotton. In 1990, the National Cotton Sales Advisory Committee put forward a proposal that the cotton tested by HVI instrument should be included in the implementation terms of the government's price protection policy, so it gradually realized that all cotton in the United States should use the HVI system for grading inspection. In additio...
