The invention discloses a landslide mass crack monitoring method which comprises the following steps: mounting a thermal imaging camera on an unmanned aerial vehicle, and photographing a landslide mass to obtain a thermal imaging image; performing temperature inversion on the thermal imaging image according to the radiance of the measured object, the transmissivity of the atmosphere, the ambient temperature and the atmospheric temperature; according to the temperature inversion result, marking cracks with the temperature higher than the environment on the corresponding visible light images; and judging the landslide state based on the marking result. The thermal imaging camera is used for observing the fracture state on the landslide body, a landslide fracture system can be remotely monitored, it is avoided that the landslide state is observed through an on-site observation method, and the personal safety of monitoring personnel is guaranteed. The crack state is observed through the infrared radiation performance, the crack position and length can be judged more accurately, and meanwhile landslide cracks which are not easy to observe by naked eyes are avoided.

    本发明公开了一种滑坡体裂缝监测方法,包括:将热成像相机挂载到无人机上,对滑坡体进行拍照,得到热成像图像;根据所测物体的辐射率、大气的透射率、环境温度、大气温度,对热成像图像进行温度反演;根据温度反演结果,在对应的可见光图像上标记出温于高于环境的裂隙;基于标记结果,判断滑坡状态。本发明利用热成像相机观测滑坡体上的裂隙状态,可以远程监测滑坡裂缝系统,避免通过现场观察法观测滑坡状态,保证了监测人员的人身安全;通过红外辐射性能来观测裂缝状态,可以更准确的判断裂缝位置和长度,同时避免肉眼不易观察到的滑坡裂隙。
