摘要 以普通相机自由运动拍摄得到的多幅非广角照片作为输入 ,提供给用户一系列简单易用的交互工具 ,从而恢复出真实场景的几何模型和表面纹理 ,最终得到具有高度真实感的三维模型 在技术路线上 ,文中系统采用按照几何空间层次分级重建的方法 ,并充分利用场景中存在的几何约束信息对重建结果进行优化 实验结果表明 ,利用该系统生成的三维模型准确真实 。 Given non-wide angle photographs acquired with a freely moving camera, the system provides the users some easy-to-use tools to reconstruct very realistic models Technically, the system adopts a stratified strategy to reconstruct 3D models, with the scene constraints used to refine the reconstruction results Experiments show that the 3D models generated by the system are sufficiently accurate and realistic to meet the requirements in the virtual reality and visualization applications
