无人机视角下海洋垃圾监测方法与空间分析OA

The current marine debris monitoring methods in nearshore waters are time-consuming and labor-intensive,with limited monitoring scope restricted to localized sampling and lacking qualitative analysis capabilities.The current marine debris classification systems based on size or material properties also exhibit significant limitations in tracing pollution sources and treatment.We used the unmanned aerial vehicle(UAV)remote sensing images to identify marine debris,and then established a novel classification framework based on industrial origin and functional use.Finally,we used the distribution density of debris to evaluate the effectiveness of marine debris management.We used this method to extract,analyze and evaluate the remote sensing information of marine debris in the nearshore waters of Sandu'ao,achieving precise manage-ment,which was conducive to the control of responsible departments from the source.
