无人机监测林业有害生物初探

Study on Monitoring Forest Pests and Diseases by Unmanned Aerial Vehicle

摘要:

摘要：为提高林业有害生物监测工作效率，提升监测工作的科技含量，特引进无人机进行监测试点。通过无人机对病虫害危害的松林进行低空航拍，然后将航片结合POS数据信息，制作出4300hm2的数字正射影像图（DOM）。随后利用松树受害后树冠颜色改变的特征，对DOM进行目视解译，再对目标虫害导致的变色枯死木进行定位标注，统计出作业区域内变色树木数量。

Abstract:In order to improve the efficiency and technology content of forest pests and diseases monitor, we specially introduced unmanned aerial vehicle to carry out pilot monitor. Firstly, Digital orthophoto map were made of low altitude aerial photos of pine trees endangered by pests and diseases，which were photographed by unmanned aerial vehicle, and POS data information. Secondly, the DOM were visually interpreted by the characteristics of pine leaves color change after damage by the pests. At last, the pines in different colors were located and marked and the number of different colors trees were counted in the working area.
