    摘要:

    針對目前獼猴桃采后人工分級費(fèi)時費(fèi)力、自動分級成本高等問題,通過機(jī)械分離輸送、圖像采集與處理、智能控制等技術(shù),研制了一套實(shí)用的獼猴桃自動分級設(shè)備。該設(shè)備包括單行定位輸送系統(tǒng)、圖像采集系統(tǒng)、分級執(zhí)行系統(tǒng)和控制系統(tǒng),通過多特征提取和融合分級的方法對獼猴桃實(shí)現(xiàn)了自動分級,同時在線監(jiān)控參數(shù)。經(jīng)試驗(yàn)驗(yàn)證,該設(shè)備按體積、形狀、表面缺陷特征分級的準(zhǔn)確率分別可達(dá)88.9%、91%、94%,融合分級的準(zhǔn)確率可達(dá)86%。

    Abstract:

    The kiwifruit automatic grading machine is an important machine for postharvest processing of kiwifruit. A set of practical automatic kiwi fruit grading machine was designed based on technologies of mechanical separation and conveyance, image capture and processing as well as intelligent control. This set of equipment mainly consisted of material storage bin, single line positioning system, image capture system and grading executive system. And it also has programs of image capture, image processing, grade determination and human-machine interaction for the host computer as well as control programs for the slave computer. By testing, this machine was capable of grading by three features of size, shape and surface defect and their grading accuracy could reach to 88.9%, 91% and 94%, respectively. And the accuracy of integrated grading could reach to 86%.
