Disaster risk investigation and key hidden dangers troubleshooting is one of the key tasks from the central government to the local government, and housing construction is the disaster bearing body that is most closely related to people's life and property safety, and is the key investigation object in the comprehensive risk survey of natural disasters. The 3D model obtained by the traditional UAV tilt photogrammetric technology has low resolution and fuzzy texture of building details, so it is difficult to comprehensively observe cracks in buildings or in dangerous bodies. In this paper, a three-dimensional modeling method of air-ground integration with near-earth images is proposed. It has been proved that this method can enrich the side texture of the 3D model of real scene of buildings, improve the model resolution, and more accurately meet the fine investigation of the disaster-bearing body of buildings.
