The invention relates to a method for monitoring the landslide of a dam slope by using an unmanned aerial vehicle to carry a hyperspectral camera. Core equipment is a multi-rotor unmanned aerial vehicle carrying a global positioning system and the hyperspectral camera. The method is mainly used for identifying a potential landslide area by monitoring vegetation change based on a hyperspectral imaging technology, and is mainly suitable for tropical island areas where vegetation is slightly influenced by climate, such as Hainan island. The unmanned aerial vehicle flies over vegetation of a dam slope at regular intervals, hyperspectral image data are obtained, and related spectral feature changes of the vegetation and soil are analyzed. Abnormal spectral change of vegetation is often related to geological instability, so that the abnormal spectral change can be used as an index of landslide early warning. According to the method, efficient, rapid and non-contact monitoring can be carried out on the large-area slope, high precision and real-time performance are achieved, and improvement of the accuracy and response speed of landslide disaster early warning is facilitated.
本发明涉及一种利用无人机搭载高光谱相机进行大坝边坡滑坡监测的方法,核心设备为搭载全球定位系统的多旋翼无人机和高光谱相机。该方法主要基于高光谱成像技术对植被变化的监测来识别潜在的滑坡区域,主要适用于热带海岛地区植被受气候影响较小的地区诸如海南岛。通过无人机在大坝边坡的植被上空执行定期飞行,获取高光谱图像数据,分析植被与土体的相关光谱特征变化。植被的异常光谱变化往往与地质不稳定性相关,因此可以作为滑坡预警的指标。本发明方法能够对大面积边坡进行高效、快速、非接触式监测,并具有高精度和实时性,有助于提高滑坡灾害预警的准确性和响应速度。
