Description

Apparatus for evaluating the quality of Kyungokgo based on multispectral images The present invention relates to a multispectral image-based Gyeongokgo quality evaluation device that enables simpler and more accurate evaluation of Gyeongokgo quality by photographing and analyzing the appearance of Gyeongokgo. The electric heating type herbal decoction pot is a means of indirectly heating the interior of the pot using a heat transfer fluid in a double-boiler manner, rapidly maintaining high temperature and pressure to significantly reduce the decoction time and enable the extraction of medicinal substances at a uniform concentration by heating the herbs uniformly. In the case of preparing Gyeongokgo using the conventional water bath method with a boiler, it takes 5 days, and in the case of preparing Gyeongokgo using the water bath method with electric heating, it takes 3 days. Since it takes about 2 to 3 hours to boil the medicinal herbs, consumers have to wait a long time, and Korean medicine clinics have to allocate excessive time and expense. Furthermore, because it is a method that heats only a part of the inside of the medicine pot, there were problems such as the medicinal herbs not being heated uniformly. Furthermore, medicinal decoction machines are limited to merely heating the interior, and there is the inconvenience of having to manufacture medicinal herbs through manual labor—which involves determining the types, quantities, and mixing ratios of herbs based solely on the know-how of specialized workers to respond to seasonal factors and changes in the surrounding environment, and then frequently checking and adjusting the process temperature. Furthermore, as medicinal herbs were manufactured based on manual labor, there was a problem where the quality of the herbs frequently varied depending on the worker and the manufacturing environment. In other words, there was a problem where it was very difficult to standardize the quality of the herbs.

FIGS. 2 and FIGS. 3 are drawings for explaining the structure of a Gyeongokgo herbal decoction pot according to one embodiment of the present invention. FIG. 4 is a diagram for explaining in detail a method for evaluating the quality of Gyeongokgo based on multiple spectroscopic images according to an embodiment of the present invention. Hereinafter, preferred embodiments are described in detail with reference to the attached drawings so that those skilled in the art can easily practice the present invention. However, in describing the preferred embodiments of the present invention in detail, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the essence of the present invention, such detailed description is omitted. Additionally, the same reference numerals are used throughout the drawings for parts having similar functions and operations. Additionally, throughout the specification, when a part is described as being 'connected' to another part, this includes not only cases where they are 'directly connected,' but also cases where they are 'indirectly connected' with other elements in between. Furthermore, the description of a component as 'including' means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. FIG. 1 is a drawing illustrating a multispectral image-based Gyeongokgo quality evaluation device according to one embodiment of the present invention. Referring to FIG. 1, the Gyeongokgo manufacturing system of the present invention includes a Gyeongokgo medicinal decoction pot (100), a process monitoring unit (200), an image capturing device (300), a quality prediction unit (400), and a process control unit (400), etc. The Gyeongokgo medicinal decoction machine (100) produces Gyeongokgo by introducing various ingredients into a container (110) and then stirring and heating the ingredients according to a preset process control value. The process monitoring unit (200) checks and monitors process conditions such as stirring speed, stirring temperature, manufacturing elapsed time, and medicinal mixing ratio through various sensors installed in conjunction with the Gyeongokgo medicinal decoction machine (100). The image capturing device (300) is equipped with a multispectral camera (310) and a thermal camera (320) to acquire and provide a total of three types of images: a multispectral image, a thermal image, and a visible image. The multispectral camera (310) acquires images for each wavelength band by using a lens and filter system to pass only light of a specific wavelength, thereby acquiring multispectral images of Gyeongokgo being manufactured by the Gyeongokgo medicine pot (100) in multiple spectral bands. The thermal imaging camera (320) captures Gyeongokgo in an infr
