Research Of Conversion Technology On Map Of The Real And Virtual Scenes

This paper makes a research on the technology of converting real scene to virtual scene, which is mainly based on the information of roads, waters and buildings. This paper presents two ideas:firstly, the algorithms of abstracting the roads, waters and buildings in the real scene map are achieved. The proper algorithm of each one of them according to its features is selected; meanwhile, different judge rules to remove the area of interference are applied. Experiments of examples are made and finally they prove the effectiveness of each algorithm. Secondly, this paper presents the method of making virtual scene maps. This method could be achieved by using professional GIS software. Then these virtual scene maps can be widely used in the area of advanced programming languages. At the same time, the paper presents the way of showing layers of multi-layers pictures.
