Matching Research of Object Model with Terrain in Multi-Scale 3D Scene

An improved method of matching used for object models and terrain models joint without gap is elucidated in this paper. We use objects' ground features as constraint conditions to inosculate objects' base interfaces with terrain surface within coordination system and rebuild a mixed digital elevation model which concerned objects ground features. We also attempt to exploit the method with level of detail model in order to reconstruct the new mixed terrain models in multi-scale 3D scene.
