中文摘要：

研究了无人驾驶直升机航空喷雾参数对药液雾滴沉积效果的影响。使用红外热像仪与无人机联用测试喷雾前、后作物冠层温度,通过温度变化率反映雾滴在水稻冠层的沉积效果。结果表明：以雾滴沉积量与冠层温度变化率为评价指标得到的结果一致,红外热成像技术可以准确反映雾滴在水稻上的沉积规律。WPH642型无人驾驶直升机作业时选取喷雾参数为：飞行高度2 m、飞行速度1.5 m/s。

英文摘要：

The influence of application parameters of unmanned aircraft on droplets deposition was researched. Temperature change rate was tested by thermal infrared imager to reflect the droplets deposit on rice canopy. The results showed that there was no difference with the droplets deposition and canopy temperature change rate as evaluation index. Thermal infrared imager could reflect the droplets deposit law exactly. The optimum application parameters of WPH642 unmanned aircraft were that flight altitude of 2 m and flight velocity of 1.5 m/s.
