摘　　要：利用无人机平台搭载真彩色相机、热成像相机和摄影机等传感器设备,开展煤田火区无人机低空飞行,获取煤田火区的真彩色影像和热红外影像,建立地表温度反演模型计算煤田地表实际温度,实现煤田火区的识别和圈定,并对火区圈定结果进行野外验证,验证结果全部正确,克服卫星热红外遥感空间分辨率低和受太阳辐射影响大的弊端,极大地提高了火区圈定的精度和效率。同时,结合煤火监测的历史数据实现火区面积的动态变化比对,监测火区的变化情况。结果表明,利用无人机热红外遥感技术进行煤田火区遥感监测是最为高效的方法。The UAV platform is equipped with true color camera,thermal imaging camera,camera and other sensor equipment to carry out low altitude flight of the UAV in the coal fire area,obtain the true color image and thermal infrared image of the coal fire area,establish the surface temperature inversion model,calculate the actual temperature of the coal field,realize the recognition and delineation of the coal fire area,and verify the delineation results in the field.It overcomes the disadvantages of low spatial resolution of satellite thermal infrared remote sensing and the influence of solar radiation,and greatly improves the accuracy and efficiency of fire area delineation.At the same time,combined with the historical data of coal fire monitoring,the dynamic change of fire area is compared,and the change of fire area is monitored.The results show that the UAV thermal infrared remote sensing technology is the most efficient method for coal fire monitoring.
