Agricultural and animal product nondestrctive detection method based on electronic visual sense and smell sense fusion technology and its device

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 the 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 hig...

After searching, there is a related Chinese patent, application number: 03131660.3, a method and device for rapid and non-destructive detection of food odor based on gas sensor array technology; there is another related US patent, patent number: 6,450,008, and the patent name is: "Food applications of artificialolfactometry( Artificial smell detection method for food)", the above invention only detects the smell of food, and the measured information is only the information on the smell of food, and the scope of application is very limited

[0005] So far, most of the quality inspections of agricultural and livestock products at home and abroad have adopted artificial sensory evaluation methods, and the detection technology of agricultural and livestock products based on a single electronic vision or smell is only in the research and experimental stage. Visual information alone Or olfactory information is also more effective in detecting the quality of some agricultural and livestock products, but the quality information characteristics detected by it are limited and incomplete after all.

For example, electronic vision can detect the appearance characteristics of fruit such as color, shape, size, etc., but it cannot detect individuals that have no obvious abnormal appearance but have deteriorated and have obvious odor
