基于三幅图像的曲面造型及纹理提取

利用标准的参数曲面来表示真实的三维曲面物体，并将物体正面、侧面及背面拍摄图像的侧影轮廓线作为约束，通过最小化线性约束下的二次目标函数实现曲面造型。将曲面重新投影到物体的正面、背面及侧面图像上，利用基于重心坐标的加权纹理提取方法提取纹理图像。利用真实图像实现了逼真的曲面造型，验证了该方法的可行性和正确性。

Curved surface modeling and texture acquisition from three images

3D curved object was represented by the standard parametric surface. The silhouettes of the images photographed from the frontal,lateral and rear positions were inputted as the linear constraints of the quadratic object function to find the smoothest curved surface of the object. The recovered surface was re-projected to the frontal, rear and lateral images of the object. Then, the pixels of the recovered texture were obtained as a barycentric combination of the colours of the near four pixels. The effectiveness of this method was demonstrated in modelling real curved objects.
