Embodiment 1

[0025] Such as figure 1 Shown, a kind of tobacco leaf thickness detection method based on laser transmittance, described method comprises the following steps:

[0026] S1: Select a number of standard tobacco leaves with known and different thicknesses to make standard samples.

[0027] In the specific implementation process, the specific method of making standard samples includes the following steps:

[0028] S11: Select several standard tobacco leaves with known thickness and different thickness;

[0029] S12: Cut the standard tobacco leaves into square tobacco leaves with a side length of 1-2 cm after removing the main vein and branch veins, which is the standard sample. Since the thickness of the main vein and branch veins is obviously greater than other parts of the tobacco leaf, removing the main vein and branch veins can ensure the smoothness of the tobacco leaves.

[0030] S2: Place each standard sample in a black box, use a laser with known intensity to incident fro...

Abstract

The invention discloses a method for tobacco leaf thickness detection based on laser transmittance. A plurality of standard tobacco leaves with known and different thicknesses are selected to manufacture standard samples, the standard samples are placed in a black box, the laser transmittance of each standard sample is detected and calculated, and a functional relation expression of the tobacco leaf thicknesses and the laser transmittance is established; the to-be-detected tobacco leaves are placed in the black box, the laser transmittance of the to-be-detected tobacco leaves are detected and calculated, and the thicknesses of the to-be-detected tobacco leaves are calculated through the functional relation expression of the tobacco leaf thicknesses and the laser transmittance. By detection in the black box, the interference of light such as sunlight and lamp light can be avoided. Compared with the prior art, the method has the advantages of being small in error, high in accuracy, quick in speed and high in efficiency.

Description

technical field [0001] The invention relates to the field of tobacco purchasing and grading, and more specifically, to a method for detecting the thickness of tobacco leaves based on laser transmittance. Background technique [0002] Tobacco buying stations buy tobacco, because the quality of field tobacco leaves is different, and the quality after modulation is also different. If good and bad are mixed, the use value will inevitably decrease, resulting in waste of resources and reduced economic benefits. The original tobacco has been processed many times, and the scientific formula can produce cigarettes with different styles that meet the requirements of consumers. The scientific formula is completed on the basis of tobacco leaf grading. Tobacco leaf grading is conducive to mobilizing the enthusiasm of tobacco farmers to produce high-quality tobacco leaves and increasing the economic income of tobacco farmers. At the same time, grading and price also point out the directio...
