基于高光谱遥感的河湖自然岸线异常监测方法、系统及设备
By using hyperspectral remote sensing technology, combined with spectral and digital model features, target points on natural river and lake shorelines are identified and near-water vertical distance differentiation is calculated. This solves the problems of monitoring errors and inaccurate water quality in existing technologies, and enables dynamic monitoring and refined management of the interaction between natural shorelines and water bodies.

AI Technical Summary
Existing technologies for monitoring natural river and lake shorelines suffer from problems such as misjudgment, missed judgment, unstable waterline position, inaccurate water quality characteristics, and difficulty in capturing dynamic coupling relationships, resulting in a lack of refinement and targeting in ecological protection and flood control management.
Using a hyperspectral remote sensing method, target points on natural shorelines are determined by spectral data features and digital model features. Water edges are identified and near-water vertical distances are calculated. Water quality characteristics of near-water points are obtained, near-water vertical distance differentiation is calculated, differentiation target points and safety points are identified, corresponding target areas are formed, and flood control reinforcement is carried out.
It achieves temporal stability in water boundary identification in complex estuarine environments, reflects the true relationship between natural shorelines and adjacent water bodies, and can identify local anomaly areas, thereby improving the scientific nature and pertinence of ecological protection and flood control management.
