Application of UAV Low Altitude Photogrammetry Technology in River-lake Health Assessment
River-lake health assessment is a fundamental work to strengthen river-lake management and protection.Low altitude photogrammetry technology based on UAV can effectively evaluate the health of river-lake's physical structure,and provide technical support for river-lake health assessment.With Manhe River in Hubei Province as research object,this paper introduces the application of UAV low altitude photogrammetry technology in the processing and data access of river-lake's physical structure assessment.Results reveal that the overall physical structure of Manhe River scored 74,indicating a sub-healthy state.UAV low-altitude photogrammetry technology works well in river-lake health assessment,with improved work efficiency,operator safety,and reduced labor intensity of operators and operating costs.
