With the increasing human demand for severe recession marine food and marine fishery resources, to ocean fishing dominated world fishery is gradually to changes in aquaculture. In recent years, China's aquaculture industry has been rapid development, but in the automation level of a big gap with foreign countries, the research and application of livestock production and automation technology has attracted wide attention.

China began to study the use of visual technology in the mid 90's, research grade or half automation more, there is a greater gap with foreign advanced technology. With the Ministry of agriculture in the new century agricultural products deep processing of the target, the domestic has been some applications of visual technology production line manufacturers, such as the Hangzhou Boshi, Tianjin felles, Yichang embossing etc.. But for seafood classification, due to the diversity of different products, with product shape appearance factors such as larger, achieve the classification of the difficult, so far at home or blank. In order to compensate for this field blank, the positive response to the call of the development of agricultural science and technology, our company has to develop the DGW-M900 oyster photoelectric sorting production line, grade production line to vision based image captured by camera seafood, through the analysis of the image processing, area, diameter and other parameters of sea products the complete product size, color, appearance, defects and damage a quality detection in many aspects, the technology for domestic initiatives. The future development direction of automatic classification will continue to visual technology as the foundation, towards diversification, multi function, photoelectric integration, development, prospect.

DGW-M900 oysters photoelectric sorting production line is the grading line is now the most advanced core technology, which is the photoelectric detection technique and image analysis technique. Machine sorting is about 80 tons per day, every month can sorting 2400 tons, 5000 tons scale manufacturers can save labor cost 1000000 or more per year, can recover the costs the first year, the benefits of about 1000000 yuan, after a year can save the cost of 2000000 yuan. Standard sorting and packaging products of high level, can greatly improve the seafood market position, to promote our country's seafood production and sales, promotion and implementation of large area.

Application and promotion of the product, to promote new agricultural science and technology progress, enhance will play an important role in the development of local economy.
