摘要: 目前我国利用无人机进行森林火灾监测、预防还处于初级阶段,森林火点的快速、准确定位在森林防火中有着重要意义,利用旋翼无人机进行林火点定位具有高效性、便捷性和低成本的优点。文章提出一种基于GPS系统和搭载摄像机的双无人机定位方法,通过在南京森林警察学院模拟火点的点烧试验,以无人机及飞控系统为主要手段获取无人机实际飞行参数、无人机航空摄影林火数据,以地面PTK GPS高精度定位系统和全站仪+PDA(笔记本电脑)进行火点精准定位,对双无人机定位精度进行检验。实验数据表明该方法精度完全满足林火监测精度要求,为未来无人机在林火监测、预防中的进一步应用提供了有价值的参考。

Abstract: Currently unmanned aerial vehicle(UAV)for forest fire monitoring, prevention is still in the initial stage in our country. The rapid and accurate location on forest fire has important significance in forest fire prevention. Based on the rotor UAV for forest fire point positioning with high efficiency, convenience and low cost advantages, this paper presents a method based on GPS and camera equipped with double UVAs. Through simulate ignition experiments in Nanjing Forest Police College, we use UAVs and the flight control system as the main means to obtain real flight parameters of UVAs to test double UAVs' positioning accuracy. The experimental data shows that the accuracy of this method meets the accuracy requirements of forest fire monitoring and provides a valuable reference for UAV’s further application in forest fire monitoring, prevention.
