The VRML modeling technology based on digital photos

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.
