基于图像处理技术快速检测茯砖茶中“金花菌”数量

Rapid Detection of the Number of “Golden Flower” Fungus in Fuzhuan Brick Tea Based on Image Processing Technology

摘要:

“金花菌”的数量是评价茯砖茶品质的重要依据之一，为了快速准确的检测茯砖茶中“金花菌”的数量，本研究利用茯砖茶中的“金花菌”颗粒较大，颜色为金黄色，清晰可辨，与其它杂菌和茶基质差异较大的特性，设计出了一种自动、快速检测茯砖茶中“金花菌”数量的方法，首先对茯砖茶进行任意面切割，并利用高分辨率拍照设备获取茶切割面图像，然后利用Image Pro Plus软件中的图像处理系统对茶切割面图像进行处理，之后采用自动计数系统对茯砖茶中“金花菌”的数量进行统计，并以人工直接计数结果为参考，结果表明：本研究方法与人工直接计数法无显著差异，检测结果可靠。因此，该方法可以有效快速准确的检测出茯砖茶中的“金花菌”数量，从而达到在线快速准确地评价茯砖茶质量的目的。

Abstract:

The quantity of “Golden Flower” Fungus is one of the important indicator for evaluating the quality of Fuzhuan brick tea. In order to quickly and accurately detect the quantity of "Golden Flower" Fungus in Fuzhuan brick tea, an automatic and rapid detection method of “Golden Flower” Fungus is designed based on that the “Golden Flower” Fungus in Fuzhuan tea is large, golden-yellow, clear and distinguishable under the naked eye. Firstly, the Fuzhuan brick tea was cut randomly, and the photographing equipment with high-resolution was used to obtain the image of the cutting surface. The Plus Image-Pro software has been employed to get the “Golden Flower” Fungus numbers of each sample automatically by image processing system and automatic counting system. The results showed that: the detection result is reliable and has no significant difference with the manual counting method. Therefore, the image processing technology can effectively and quickly detect the “Golden Flower” Fungus in the Fuzhuan brick tea, so as to quickly and accurately evaluate the quality of the Fuzhuan brick tea.
