摘要
通过在农药中加入示踪粒子,利用高速摄像机采集喷雾机农药与清水通过混药器在线混合后流体混合图像的方法,研究了喷雾机农药与水在线混合的混合效果。对于原始粒子图像均匀度较差的问题,提出了基于形态学的校正方法,利用灰度增强的Otsu法对粒子图像进行了有效分割,提取了粒子质心坐标等参数。
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.
