| 为探寻无人机(UAVs)监测广西松材线虫病疫区的适宜航高，本研究选取实际监测工作中应用最多的代表型无人机M3E和P4R，对同一区域分别以100、300、500 m 3种航高采集数据，并采用人工判读的方法对影像中的松树（Pinus L.)枯死木进行识别，确定不同航高下无人机的作业效率与识别准确率。结果表明：(1) 100 m航高下M3E、P4R无人机的作业效率最低，分别为112.87 hm2/h和73.97 hm2/h,但识别准确率最高，分别为98.08%和92.59%；(2) 300 m航高下M3E、P4R无人机的作业效率分别为349.77 hm2/h和180.45 hm2/h,识别准确率分别为87.93%和87.50%；(3) 500 m航高下M3E、P4R无人机的作业效率最高，分别为555.51 hm2/h和333.31 hm2/h,但识别准确率最低，分别为69.70%和53.33%。综合考虑无人机的识别准确率与作业效率，300 m航高是实际工作中最适宜的飞行高度。本研究结果可为无人机监测广西松材线虫病疫区的实际工作提供理论参考。 |

| Abstract: |
| The aim of this study is to explore a suitable flight altitude for UAVs monitoring of pine wood nematode-infected areas in Guangxi.The representative UAVs of M3E and P4R,commonly used in actual monitoring work were used to collect data from the same study area at three different flight altitudes of 100,300,and 500 m.The dead pine trees in the images were manually identified,and the operational efficiency and recognition accuracy of UAVs at different flight altitudes were measured.The results showed that:(1)At the flight altitude of 100 m,M3E and P4R had the lowest operational efficiency of 112.87 hm2/h and 73.97 hm2/h,but had the highest recognition accuracy of 98.08% and 92.59%,respectively.(2)At the flight altitude of 300 m,M3E and P4R showed the operational efficiency of 349.77 hm2/h and 180.45 hm2/h and the recognition accuracy of 87.93% and 87.50%,respectively.(3)At the flight altitude of 500 m,M3E and P4R had the highest operational efficiency of 555.51 hm2/h and 333.31 hm2/h,but had the lowest recognition accuracy of 69.70% and 53.33%,respectively.Taking into account the recognition accuracy and operational efficiency of UAVs,300 m is the most suitable flight altitude for practical work,which can provide a theoretical reference for UAVs monitoring of pine wood nematode-infected areas in Guangxi. |
