Problems solved by technology

However, the detection of saponin content by high performance liquid chromatography takes a long time, has low work efficiency, and requires professional equipment and personnel to detect. It is not economical and is not suitable for the general population, which will affect the quality of Sanqi purchased by the general public.
Such a method is not suitable for the public and cannot meet the actual needs.

Embodiment Construction

[0026] The technical scheme adopted in this specific embodiment is: a kind of notoginseng saponin rapid detection method based on computer vision technology, and it comprises the following steps:

[0027] Step 1. Preparation of notoginseng samples: purchase a certain number of notoginseng samples according to the demand, and the purchased notoginseng samples are common pure natural insect-free notoginseng;

[0028] Step 2, the processing of the notoginseng sample: wash the notoginseng sample prepared in step 1 with clean water, then air-dry it, and set it aside;

[0029] Step 3, image collection: use a CCD camera to collect images of the surface texture of the processed Panax notoginseng, and obtain a clear Sanqi surface texture image;

[0030] Step 4, image processing: Carry out image segmentation, denoising, image enhancement, edge extraction, image addition and feature value extraction on the surface texture image of notoginseng, and use the method of support vector machine...

Abstract

The invention discloses a fast detection method for Panax notoginseng saponins based on a computer vision technology, and relates to the technical field of food safety detection. The method comprisesthe steps of first, preparing a Panax notoginseng sample; second, processing the Panax notoginseng sample; third, collecting an image, namely, carrying out image collection on the surface texture of the processed Panax notoginseng by using a CCD camera to obtain a clear Panax notoginseng surface texture image; fourth, processing the image, namely, carrying out image segmentation, denoising, imageenhancement, edge extraction, image addition and eigenvalue extraction on the Panax notoginseng surface texture image, and performing fast recognition and classification on the Panax notoginseng texture by adopting a support vector machine supervised classification method; fifth, detecting according to a high-performance liquid chromatography method; sixth, building an image model; and seventh, obtaining data. The fast detection method for the Panax notoginseng saponins based on the computer vision technology has the beneficial effects of short time consumption, high efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of food safety detection, in particular to a rapid detection method of notoginseng saponins based on computer vision technology. Background technique [0002] Panax notoginseng, the name of traditional Chinese medicine. It is mainly produced in Wenshan Prefecture, Yunnan, so it is named Wenshan Sanqi, also known as Wenzhou Sanqi, which is the dry root and rhizome of Panax notoginseng (Burk.) F.H.Chen, a plant of Araliaceae. Excavate before the flowers bloom in autumn, wash, separate the main root, branch root and rhizome, and dry. Branch roots are traditionally called "tendons", and rhizomes are traditionally called "cuts". 1. The main root is conical or cylindrical, 1-6cm long and 1-4cm in diameter. The surface is grayish brown or grayish yellow, with intermittent longitudinal wrinkles and branch root marks. There is a stem scar at the top, and there are tumor-like protrusions around it. Body weight, s...
