Embodiment Construction

[0035] The present invention has versatility to the non-destructive testing of agricultural and livestock products, but because there are many kinds of agricultural and livestock products, the present invention only gives an embodiment for red Fuji apples, and the detection of other agricultural and livestock products can refer to the method of this embodiment, 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.

[0036] This embodiment refers to image 3 , a schematic diagram of a system scheme for detecting apples in the present invention. First select apples of various quality grades in accordance with national standards, first carry out quality assessment and grading according to conventional testing methods, and then use these apples as standard samples to conduct nondestructive testing with a nondestructive testing device based on electronic vision and olfa...

Abstract

Images of farm animal products taken by CCD camera through image acquisition card are transferred to computer. Under certain condition (temperature, humidity and flow rate), smells emitted from farm animal products through mini pump with no oil are sucked into reaction chamber, where signals are generated by array of gas sensor. The said signals through conditioning circuit, A / D acquisition card are transferred to computer. Computer for simulating human brain to treat vision data and smell data carries out syncretizing and pattern recognition processing. Combining with experts' knowledge in knowledge base as well as experiences, computer makes judgment for qualities of garden spgarden stuff, meat and corns etc. synthetically.

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 electronic vision and olfactory fusion technology. Background technique [0002] Due to the lack of high-quality and high-level testing methods, the phenomenon of mixed grades and mixed grades of my country's exported agricultural and livestock products is serious, and it is in an extremely disadvantageous position in the international market competition, and its market share is constantly challenged. my country is a large agricultural country. After joining WTO, the situation of agricultural and livestock products is becoming more and more severe. At present, the quality inspection of most agricultural and livestock products still uses artificial sensory evaluation methods and conventional chemical analysis methods. Conventional chemical analysis has high a...
