纹理映射中的平面校正技术研究

The Research of Planar Rectification in Texture Mapping

为了快速实时地进行由平面组成的结构景物的3D建模问题,文中介绍了一种在进行图像3D重构时纹理映射中的平面校正方法。介绍了三角形模型在图像处理、图形绘制、虚拟现实等技术中的重要作用。从射影几何的角度出发,给出了从两幅视图进行景物三维重构的分层重构方法。在已知欧氏重构即摄像机内参数的基础上,介绍一种基于标定的平面射影失真矫正方法。通过此方法,将矫正过的纹理映射到欧式点重构结构中,得到景物的3D模型。经实验验证,这种方法在处理由平面组成的景物的3D重构中是实时有效的。

Introduces an effective method of planar rectification in texture mapping. Firstly introduces polygon model which acts greatly on image processing, image rendering, virtual reality and so on. Then introduces a hierarchical reconstruction from two images knowing how projective geometry enables the reconstruction of 3D point locations visible in two images. Under the known camera internal parameters circumstance, uses a good method of rectifying the perspective distortion. After rectifying, can map textures from the original images onto the planar surfaces of the polygon model and get a good 3D model of the scene.
