【摘要】：針對世界四大主要油料作物之一的向日葵種子的分選問題,結(jié)合近紅外技術(shù)和計算機(jī)視覺技術(shù),進(jìn)行了根據(jù)向日葵種子內(nèi)部含油率高低不同的自動分選系統(tǒng)設(shè)計開發(fā)。依據(jù)不同含油率種子在近紅外光下的成像特征,將向日葵種子區(qū)分為兩個級別。該系統(tǒng)由Labview計算機(jī)視覺系統(tǒng)、紅外光發(fā)生器、圖像采集卡、黑白照相機(jī)、40 W的環(huán)形燈、白色的照相紙及X射線圖像處理工作站組成。運(yùn)用所設(shè)計樣機(jī)進(jìn)行向日葵種子分選試驗(yàn),結(jié)果表明:與化學(xué)分析方法相比較,本系統(tǒng)設(shè)計含油率分選準(zhǔn)確,從而為滿足不同市場需求的向日葵種子分選提供一種方便、快捷的方法,提高了向日葵種子的市場價格經(jīng)濟(jì)效益。
[Abstract]:Aiming at the problem of seed sorting of sunflower, one of the four major oil crops in the world, combining near-infrared technology and computer vision technology, According to the inner oil content of sunflower seeds, an automatic sorting system was designed and developed. According to the imaging characteristics of seeds with different oil content in near infrared light, The sunflower seeds are divided into two levels. The system consists of a Labview computer vision system, an infrared light generator, an image acquisition card, and a black-and-white camera with a 40W ring light. The white photographic paper and X-ray image processing workstation were used to carry out the seed sorting test of sunflower by using the designed prototype. The results showed that compared with the chemical analysis method, the oil content of the system designed by this system was accurate. Thus, it provides a convenient and quick method for the seed sorting of sunflower to meet the different market demand, and improves the market price and economic benefit of sunflower seed.
