摘要
本文首先简单介绍了虚拟现实建模技术及利用照片建模的流程,着重阐述了基于特征点的三维网格模型重建算法,然后分析了3种算法的误差,通过试验选出最佳的重建算法。文中的实例重建了某汽车覆盖件的3D网格模型,验证了该算法的可行性,达到了较为理想的效果。
Firstly,this paper briefly introduces several ways to construst VRML models and steps of Image-Based modeling with the main concern in the algorithms of recontrusting a 3D mesh model based on feature points.After that,we discuss their errors experimentally and choose the best algorithms.We reconstrust the 3D mesh model of a Car covering part,and the algorithm is verified by the example.The result is satisfied fairly.
