Method and device for non-destructive testing of agricultural and livestock products

Abstract

A non-destructive inspection and device for agricultural and livestock products. The method uses a camera to capture images of agricultural and livestock products transmitted on a conveyor belt in real time, including: acquiring in real time a video frame image of the currently captured video content; performing item identification from the video frame image , and extract the main color information; according to the main color information, select qualified agricultural and livestock products. The non-destructive testing method and device for agricultural and livestock products first uses visual technology to perform image recognition on the agricultural and livestock products transmitted on the conveyor belt, and screens out a part of the agricultural and livestock products that may have problems due to their appearance color, and then checks the screened agricultural and livestock products Smell re-inspection using electronic sense of smell can ensure fresh and healthy agricultural and livestock products after inspection.

Description

technical field [0001] The invention relates to the technical field of food testing devices, in particular to a nondestructive testing device for agricultural and livestock products. Background technique [0002] People depend on food, and the quality of agricultural and livestock products is the key to quality control. In order to realize the health inspection of the quality of agricultural and livestock products, at present, non-destructive testing technology has been gradually popularized to meet the needs of large-scale processing in food production and processing. The characteristics of pollution or less pollution are easy to realize automation, which is often realized by computer olfactory technology, near-infrared spectral analysis technology or visual analysis technology. [0003] Computer olfactory technology is generally a technology that uses gas sensor arrays to identify and detect complex smells and volatile components. It is more effective for the detection of...

AI Technical Summary

Problems solved by technology

If another set of testing equipment is established, the same process is required to realize it, and the initial investment is relatively high, which is relatively time-consuming

[0005] With the progress of image analysis technology, the quality inspection of agricultural and livestock products based on vision technology has been gradually applied in recent years, mainly through the appearance characteristics of the size, shape, texture, color and surface defects of agricultural and livestock products for quality inspection and sorting , however, only by judging external features, the internal situation is often not detected, and the accuracy of existing image detection algorithms is not high
