Embodiment Construction

[0030] The present invention has versatility to the nondestructive detection of agricultural and livestock products, but because there are many kinds of agricultural and livestock products, the present invention only gives an implementation example for red Fuji apples, and the detection of other agricultural and livestock products can refer to the method of this implementation example, Specifically aiming at the evaluation criteria of the tested samples, a new knowledge base can be established to test this kind of agricultural and livestock products.

[0031] The main components of the hyperspectral image detection device are composed of a computer 1, an image acquisition card 2, a camera 3 (using a linear array detector as a sensitive element), an image spectrometer 4, a halogen lamp (composed of two 150W strip lights placed in parallel) tube 5, optical fiber 6, and light source 7), two symmetrically placed ultraviolet lamps 8, a transmission device 9, and a lighting room 10, ...

Abstract

The invention relates to high optical spectral image technique without harm to agricultural products. It can reflect the appearance of the agriculture products like color, shape, texture, dimension, scar and son on, and internal features like hardness, protein content and connected with knowledge base and experience of experts to make judgment. It can make quick, accurate, timely judgment of products, controlling the overall production with guarantee of the agriculture quality.

Description

technical field [0001] The invention relates to a detection method for agricultural and livestock products, in particular to a non-destructive detection method and device for agricultural and livestock products based on hyperspectral image technology. Background technique [0002] For a long time, the quality problem of agricultural products has been plagued the circulation field of our country. Good and bad agricultural products are uneven, which is not conducive to the price evaluation of agricultural products according to quality in circulation, and is not conducive to foreign exchange earning through export. At present, all countries in the international market put quality issues first, and use quality inspection as a means to resist foreign competition. The quality inspection and classification technology of agricultural products in my country is still quite backward. Generally speaking, it is still in the stage of manual or simple mechanical rough inspection and canno...
