The invention discloses a method for quickly checking the position of a sewage draining exit entering a river or sea, which comprises the following steps of: performing remote sensing detection through an airborne hyperspectral imager of an unmanned aerial vehicle, performing water quality monitoring on the sewage draining exit under the water surface of the river or the sea, and reducing the position of the sewage draining exit according to a water quality monitoring inversion result; and then the specific position of the sewage draining exit is detected and confirmed through the underwater sonar of the unmanned ship. Through hyperspectral remote sensing image analysis, hydrogeological information of a water environment system in a specific area can be obtained, and data support can be provided for recognition and real-time monitoring of a hydrogeological environment, efficient management of underground water resources, construction of an underground water numerical model and the like. Therefore, the method that the unmanned aerial vehicle-mounted hyperspectral remote sensing system is matched with the unmanned ship-mounted underwater sonar detector to monitor and recognize the position of the river-entering and sea-entering sewage draining exit is adopted, long-term periodic monitoring on the water environment is facilitated, the method has wide application prospects, and a win-win situation is achieved on improvement of the working efficiency and protection of the river and sea water ecological environment.
本发明公开了一种快速排查入河入海排污口位置的方法,通过无人机机载高光谱成像仪进行遥感检测,对河流或海洋水面下的排污口进行水质监测,根据水质监测反演结果缩小排污口的位置,然后通过无人艇水下声呐探测确认排污口的具体位置。通过高光谱遥感图像分析,能够获取特定区域内水环境系统的水文地质信息,可为水文地质环境的识别及实时监测、地下水资源高效管理、地下水数值模型构建等提供数据支撑。因此,采用无人机载高光谱遥感系统,配合无人艇搭载水下声呐探测仪监测识别入河入海排污口位置的方法,便于对水环境进行长期的周期性监测,本方法有着广阔的应用前景,在工作效率的提高与河流、海洋水生态环境的保护上实现双赢。
