摘　　要：针对实景三维模型在实际使用中需要单体化的问题,提出一种基于实景三维模型的单体化模型重建技术。基于实景三维模型、空三成果、倾斜摄影航片和手持拍摄照片进行三维模型的重建,并进行了实验。结果表明,该方法能够快速完成三维模型重建,重建的三维模型有较高的还原度和精度,满足LOD(Levels of Detail,多层次细节)3级别模型的要求。Aiming at the need of monomeric model in reality application,a methodology of monomeric model reconstruction based on real 3D model was proposed in this paper.The model reconstruction was carried out through aerial triangulation,oblique aerial photography and handheld pictures texture processing.The experimental results showed that the method could quickly complete the model reconstruction with a high precision,which could meet the definition of Levels of Detail(LOD)3.
