基于影像方位信息的三维建模关键技术研究与应用

Research and Application of Key Technology of 3D Modeling Based on Image Azimuth Information

三维模型以其直观性、客观性和真实性等特性,成为数字城市建设的重要组成部分。本文针对传统三维建模纹理检索、纹理映射存在的一些问题,主要利用纹理、模型的方位信息,对三维建模的关键技术纹理检索、纹理映射进行研究,改进传统三维建模纹理检索不高的缺陷,并利用OpenGL纹理映射进行三维建模实验,通过实验验证本文讨论方法的可行性,以期在实际的三维建模生产中能够进行应用。

The three-dimensional model has become an important part of the construction of digital cities for its characteristics of intuition,objectivity and authenticity.Some problems existing in traditional texture mapping,three-dimensional modeling,texture retrieval,mainly use the orientation information of texture,texture model,the key technology of 3D model retrieval,texture mapping research,improve the traditional 3D modeling texture retrieval defects is not high,and the three-dimensional modeling experiment using OpenGL texture mapping,through the experiments discussed in this paper the feasibility of the method,in order to be applied in actual production in 3D modeling.
