Application of UAV Oblique Photography and Real 3D Scene Modeling Technology in Emergency Surveying and Mapping:A Case Study of the 6·23 Hutang Landslide in Wuxi
Emergency surveying and mapping plays an indis-pensable and crucial role in disaster prevention,reduction,and relief work in a new era of socialism with Chinese Charac-teristics.The paper introduces the technical advantages of UAV oblique photogrammetry and;real 3D scene technology in emergency surveying and mapping,and elaborates on the workflow of unmanned aerial vehicle tilt photography and;re-al 3D scene emergency surveying and mapping.Under poor basic support conditions such as equipment placement and power supply,the innovative use of"Cloud Earth"to com-plete the construction of a real 3D model is carried out,and the spatial analysis of the Hutang landslide was carried out based on this real 3D model.The analysis results provide strong data support for various work such as investigation and monitoring,emergency rescue and disaster analysis,com-mand and decision-making of relevant departments,evacua-tion and rescue,and monitoring and warning.
