Abstract <br>In recent years, with the continuous development of digital mapping technology, tilt photogrammetry technology is being widely used at home and abroad with its advantages of large range, high precision, high definition and comprehensive perception of complex scenes. At present, the use of unmanned aerial vehicles to shoot oblique images of ground features to build a three-dimensional model of the real scene, there are already more mature technical methods and data processing software, the measurement and production of the real three-dimensional model has always been a hot topic of exploration and experiment Using the two-dimensional and three-dimensional linkage integrated measurement software EPS to generate digital orthophotos and real-world three-dimensional models by Context Capture for DLG acquisition, so as to realize the mapping and updating of geographical elements. <br>Keywords: 3D model; EPS; tilt photogrammetry; DLG
