    摘要:

    通過(guò)在農(nóng)藥中加入示蹤離子，利用高速攝像機(jī)采集噴霧機(jī)農(nóng)藥與清水通過(guò)混藥器在線混合后了流體混合圖像的方法，研究了噴霧機(jī)農(nóng)藥與水在線混合的混合效果。對(duì)于原始粒子圖像均勻度較差的問(wèn)題，提出了基于形態(tài)學(xué)的校正方法,利用灰度增強(qiáng)的Otsu法對(duì)粒子圖像進(jìn)行了有效分割，提取了粒子質(zhì)心坐標(biāo)等參數(shù)。

    Abstract:

    In order to investigate the mixing effect of pesticide and water in sprayer, the mixing image in the mixer was acquired by a high speed camera through adding tracing particles in pesticide. And a new method using morphology to improve the nonuniformity was developed for the original mixing image. Then the mixing image was segmented by the method of gray-enhancing Otsu effectively. The parameters such as the coordinate of the particle's centroid were also calculated.
