摘　　要：针对从轮廓恢复形状获得的几何模型,为使其具有真实感,提出了一种基于自由多视角的图像序列为几何模型添加表面纹理的新方法,解决了以往二维图像和三维几何模型配准方法中需人工干预、低精度,速度慢的问题。本文通过设计一个配准模板,实现了全自动、高精度的配准,并利用透视投影变换一次性获得纹理坐标,实现了快速的纹理恢复。实验结果表明,采用这种方法的纹理绘制效果理想,生成的模型真实感强。An automatic method of mapping the texture from multiple calibrated camera views onto a 3D model which is estimated using a shape - from - silhouette approach is presented in this paper. It solves the problems in the previous method of the registration between 2D images and 3D geometry model by designing a novel registration pattern and making use of texture mapping method based on perspective projection, and achieves the goal of automatic, high accuracy and fast. The experiments have confirmed the suitability of this proposed method, and the result is acceptable and satisfactory.
