The invention provides a method for realizing inspection and fire extinguishing of an unmanned aerial vehicle in forest fire prevention, and the method comprises the steps: obtaining an electronic map of a to-be-inspected area by the unmanned aerial vehicle, and confirming an inspection route according to the electronic map and flight time; after the unmanned aerial vehicle takes off, the infrared camera shoots a color image of the inspection area and analyzes a flame image from the color image, if no flame exists, inspection continues, and if flame exists, an alarm is given out, and fire extinguishing is carried out; and shot and extinguishment color images are wirelessly transmitted to the control platform to confirm that extinguishment is completed. The image is analyzed to obtain the sharp corner number at the position, whether the sharp corner number reaches the preset threshold value or not is judged, if the sharp corner number reaches the preset threshold value, the unmanned aerial vehicle descends, open fire is confirmed, and fire extinguishing is started; according to the invention, multiple functions of the unmanned aerial vehicle are realized, the unmanned aerial vehicle can inspect and extinguish fire, the intelligent control level of the unmanned aerial vehicle is greatly improved, and automatic inspection, automatic discovery, automatic judgment and automatic fire extinguishment are realized.
本发明提供了一种实现无人机在森林防火中的巡检与灭火方法,方法包括:无人机获取待巡检区域的电子地图,根据电子地图和飞行时间确认巡检路线;无人机起飞后,红外摄像头拍摄巡检区域的彩色图像,并从彩色图像中分析出火焰图像,若没有火焰,则继续巡检,若存在火焰,则发出报警,并进行灭火;拍摄及灭火的彩色图像无线传输至控制平台,确认灭火完成。本发明通过对图像进行分析得到此处的尖角数,判断尖角数是否达到预设阈值,若达到阈值无人机则下降高度,确认是明火,则开始灭火;实现了无人机的多功能,不能能够巡检,而且能够进行灭火,极大地提升了无人机的智能控制水平,实现了自动巡检,自动发现,自动判断及自动灭火。
