摘　　要：利用无人机平台搭载航摄相机、热像仪、摄像机等传感器,在煤田火区开展可见光航空摄影测量、热红外遥感成像和摄像,能发挥低空、灵活、高清低成本的优势,用于编制大比例尺DOM、DSM(DEM)和等温线图,消除了卫星遥感在热红外波段空间分辨率太低和受太阳辐射影响严重的缺陷,极大地提升煤田火区遥感调查的效率和精度。借助于两期或多期无人机遥感成像,可以实现对火区的动态监测、计算灭火施工的土方量,监测灭火效果。实践证明,利用遥感探测技术组合是当前煤火遥感调查最为高效的方法。Using drone platform to carry aerial camera,thermal imager and video camera etc sensors carrying out visible aerial photogrammetry,thermal infrared remote sensing imaging and camera shooting can exploit advantages of low altitude,flexible,high resolution and low cost into full play.If using the technology to compile large scale DOM,DSM(DEM)and isothermal diagram can eliminate satellite remote sensing serious deficiencies of too low thermal infrared bands spatial resolution and serious solar radiation effects,enormously increased coalfield fire area remote sensing investigation efficiency and precision.By means of two or multiple drone remote sensing imaging can realize fire area dynamic monitoring,estimate extinguishing operation earth quantity,extinguishing effect monitoring.Practices have shown that to use remote sensing detection technology assemblage is the most efficient method in coalfield fire remote sensing investigation at present.
