【摘要】 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。更多还原

【Abstract】 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.更多还原
