| 摘 要： | 用数码相机拍摄建筑物的立面相片 ,经PhotoShop处理、校正后获得建筑物三维几何模型的影像纹理 ,然后利用VC ++调用OpenGL图形库编程 ,建立了具有影像纹理的高度真实感三维城市景观模型。实践证明 ,在缺乏航空及遥感影像数据的地区 ,该方法可用来实施数码城市工程的建设。

| Abstract: | The 3D cityscape models built using dint of some computer aided design and animation kit software are difficult to be controlled by users and lacking in interactivities. In order to solve the above-mentioned problems, a new modeling method was proposed. Firstly the facades of buildings are photographed with a digital cameral. Then the digital photographs are calibrated with PhotoShop to acquire the image textures of 3D geometric models. Finally a new 3D cityscape model with real image texture is built with VC++ and OpenGL databases. It is proved that this method can be applied to carry out the construction of city project in the area lacking in photogrammetric or RS image data. |
