摘要
针对植保机械雾化性能检测中对雾滴尺寸分布特征检测常用方法中存在的不足,提出了利用高速摄像结合数字图像处理技术对药液雾化场中空间雾滴特征参数进行检测统计的方法,并根据检测到的雾滴特征参数信息实现了雾滴分布图像的二维重建。试验结果表明,该方法实现了对喷雾场中的雾滴分布特征的快速准确检测,同时避免了对喷雾场的干扰,为进一步研究喷雾场中的雾滴分布特征以及运动情况提供了方法基础。
In order to solve the faults in usual measurements of the characteristic of droplet distribution, a new measurement method combining high speed imager with digital image processing for the droplet size distribution analysis in spray field was presented. Meanwhile it can reconstruct the photo of droplet distribution based on the droplets＇ characteristic. The new measurement method can avoid the interference in spray field, at the same time, it can detect the droplet parameters quickly and accurately, and provide the basic way for the research on droplet motion in spray field.
