Background technology

Fruit is to maintain the human health necessary vegetable basket food of life and nourishment food.Recent two decades come, World Water Fruit industry development is rapid, and current world fruit always produces more than 6.3 hundred million tons.China is described as the mother of world's gardening, is also current generation Maximum Production of fruit state of boundary and country of consumption, China's fruit gross area reaches 1.82 hundred million mu within 2012, always produces more than 1.5 hundred million tons, the whole nation , respectively more than 150,000,000,000 yuan and 111,000,000,000 yuan, China's Development of Fruit Industry is for guarantee state for Fructus Mali pumilae, Citrus initial product annual value of production Interior market supply, increase farmers' income, improve the ecological environment and promote rural economic development etc. tool be of great significance.

Citrus are unique flavors, nutritious fruit, are well received by consumers.2008 start, and China is for the first time Surmounting Brazil becomes the first in the world big Orange Producing state.2012, China's Orange Producing sustainable development, Citrus area 230.63 ten thousand Hectare, 3167.78 ten thousand tons of yield, account for 923.17 ten thousand hectares of world's Citrus area, 24.98% He of 1.29 hundred million tons of yield respectively 24.56%.In domestic Fruits production, Citrus area tops the list, and yield is only second to 3849.04 ten thousand tons of Fructus Mali pumilae, comes second, area and Yield accounts for the 18.99% and 20.79% of fruit total amount respectively.

Citrus Industry international or domestic all have huge economic market, in order to lift citrus fruit quality At home and international market competitiveness, the Cai Hou automatization rapid classification technology of citrus fruit receives much concern always.In recent years, Some universities domestic such as Zhejiang University, such as Yangzhou Fuerxi Fruit Vegetable Juice Machinery Co., Ltd. of processing fruits factory etc. all have been developed over More ripe commercialization Quality Parameters in Orange grading production line, the graded index of these classification lines lays particular emphasis on fruit size, color, shape Shape and weight.Automatization's quick detection of skin defects is still a very challenging problem, becomes domestic and international at present Researcher is in one of fruit automatization field of fast detection focus of attention.

With other common External Defects compared with cicatrix, the corruption being caused by fungal disease infection is citrus fruit most serious Defect, it is to lead to the corrupt main reason of fresh Citrus in storage and transport process that fungal disease infects.Such as, research in recent years is sent out Existing, after China's Citrus that fungal infection causes are adopted, corrupt 80% is caused by Penicillium digitatum penicillium digitatum, secondly Italian penicillium sp penicillium italicum, this two classes disease may result in Citrus adopt rear Decayed rate up to 30%～ 50%.
