AI Technical Summary

Problems solved by technology

However, this technology cannot directly obtain color parameters, so it cannot intuitively describe and evaluate the color of tea leaves
In addition, due to the need to obtain image information of different wavelengths, the amount of collected data is large, and the post-processing is complicated, so it is currently mainly used in laboratory research on tea, not suitable for industrial rapid measurement requirements

Embodiment Construction

[0031] Embodiments according to the present invention will be described in detail below in conjunction with the accompanying drawings. It should be pointed out that these drawings are only schematic and not necessarily drawn to scale, and do not limit the protection scope of the present invention.

[0032] The light source of the present invention preferably adopts a broad-spectrum light source capable of emitting 380nm-780nm visible spectrum, such as bromine tungsten lamp. A gradient frosted glass 14 is arranged in front of the lamp, and the gradient frosted glass 14 can have different transmittances in different places according to the light intensity of the light source, so as to meet the requirement of uniform distribution of light intensity emitted after passing through the frosted glass. The probe field of view is illuminated at 45° with this light source. The detection field of view is the horizontal plane where the surface of the tea leaves described later is located....

Abstract

The invention relates to a spectral method of color measurement, characterized by that: according to reflectance spectrums of a standard board and a comparative substance, establishing a color parameter database, carrying out data fusion between the collected color feature parameters of the substance to be measured and the color parameter database, and carrying out pattern recognition. According to the invention, a rapid, simple and objective measurement of the color of the substance is provided, the impacts of artificial factors, change of time and space and other uncertainties in the traditional subjective visual method on the accuracy of the measurement are avoided, so that the justice and fairness of the measure result is guaranteed.

Description

technical field [0001] The invention relates to a spectral color measurement method, which can be used for non-destructive detection of plant seeds, leaves and other substances. Background technique [0002] How to accurately and objectively evaluate materials such as seeds and leaves piled up together, or finely divided industrial products piled up together, has always been a problem that people are pursuing to solve, and certain results have been obtained. Take tea as an example below. [0003] As a traditional natural beverage, tea has been welcomed by the world. With the growth of tea consumption, the evaluation of tea quality becomes more and more important. However, the color of tea leaves is mainly evaluated by subjective visual method, which is prone to errors due to the influence of human factors and uncertain factors such as time and space changes, and it is difficult to make an objective evaluation. [0004] The main methods used in the laboratory for objective...
