Abstract
The current digital elevation model(DEM)and digital orthophoto map(DOM)fusion modeling faces challenges such as less data format,single method,and incorrect coordinate information,and it is easy to form model loopholes.To address these issues,a fast fusion-based reverse modeling method based on DEM and DOM data was proposed,which combined reverse modeling of point clouds and geometric terrain surface modification technology to quickly complete the reconstruction process of realistic three-dimension(3D)models.Taking the Yanmengou watershed in Wenchuan County as the research area,this paper presented the technical flow of the fast fusion-based reverse modeling scheme.The results show that the model results obtained by this method have good reliability and high accuracy,effectively solving the specific problems caused by the applicability of the algorithm,such as the void of the model and the low fineness of the model.The method provides a new implementation path for the construction of realistic 3D models and has an important application prospect.关键词
