| 摘 要： | 根据旋转面的轴线与其表面顶点法矢相交的几何准则,提出一种估计轴对称破碎文物轴线的几何方法,进而获得文物碎片的母线信息,生成具有内外表面的文物复原模型.最后,采集破碎文物的纹理并对其进行必要修复后对复原模型进行渲染,得到三维虚拟文物,展示在考古数字博物馆中.

| Abstract: | Based on the principle that the normal vector of a point from the surface of revolution intersects its rotational axis, a geometric method is proposed to estimate the axis of fragmented relic and restore its profile curve. Revolving the profile around its axis generates the original model with both inner and outer surfaces. Textures of the relic are collected and painted onto the model for exhibition in the Digital Museum of Archaeology. |
