Research on Integrated Construction of 3D Geological Model Based on Multi-source Data
With the development of 3D modeling in China,higher requirements have been put forward for 3D modeling of geology.There-fore,an integrated construction method of 3D geological model based on multi-source data is proposed in this paper.Through the UAV tilt photogrammetry and geotechnical investigation technology,the surface image and drilling data are obtained.At the same time,curvature filte-ring algorithm and Kriging interpolation method are used to preprocess the data,and the three-dimensional ground and formation data in the study area are obtained.Civil 3D surface creation function is used to build surface and surface of various layers,and combined with surface ed-iting function to check and reorganize triangulation errors.In addition,the topological and geometric relationship between the two adjacent stra-ta is established to realize the rapid construction of an integrated 3D geological body model.Taking the project of Mouding County as an exam-ple,the proposed method is verified,and the results show that the method can display the geological distribution directly and reflect the geolog-ical situation truly,and has strong practicability.
