【摘要】 通过模拟田间实际喷雾情况,利用图像采集系统采集雾滴图像,对其进行增强和分割等预处理,并对粘连雾滴提出用改进的分离粘连雾滴算法进行了分离处理。基于相同样本,用图像处理方法获得的雾滴粒径分布及覆盖率等参数与激光粒度仪测量结果的对比分析表明,利用图像处理技术检测雾滴分布参数,其测量误差在6%以内。更多还原

【Abstract】 The droplet size distribution is evaluated by image processing.The traces of the captured droplet on water-sensitive papers are detected by a camera and then sent for segment and evaluation by a specially developed program.An improved GLV algorithm is used to separate the conglutinated droplets and compute their size data comparing to the discrete droplets.Comparison experiments are conducted to measure the droplet size distribution by a laser particle size analyzer.The evaluation result shows that the error between the data set given by image process and the data set from laser analyzer is less than 6%.更多还原
