摘　　要：针对古建模型的快速重建,提出了一种基于样例的古建模型快速重建方法。该方法采用基于激光扫描仪等设备的建模方法、基于多幅照片的建模方法和手动建模方法构建中国古建构件模型库;在此基础上采用基于语义和草图的三维模型检索方法在古建模型构件库中检索所需模型构件,选择最近似模型;在自主开发的虚拟现实快速模型构建平台VR Studio上实现快速古建模型构建;使用重建的古建模型构建三维场景。提出的方法大大加快了古建模型建模速度,且用其构建的场景具有较好的真实感。In order to do fast reconstruction for ancient architectures, an example-based method for fast reconstruction of Ancient Architectures was proposed. This method first used many modeling methods to build the component model library of Chinese ancient architecture. These methods contain laser scanner-based modeling method, multiple photos-based modeling method, and manual modeling method. Then, semantic and sketch 3D model retrieval methods were used to retrieve the required model components and select the most similar models; Then, fast reconstruction of Ancient Architecture was achieved using the VR Studio platform developed. After that, a 3d virtual scene was built using the reconstructed architecture model. The proposed method greatly accelerates the speed of modeling and the scene built has a considerably great sense of reality.
