Accurate reconstruction of free-formed objects was very difficult, owing to error of feature extracting and matching in 3D Reconstruction. A method that reconstructs object by using Quadric Spline Curves as primitives was proposed.
在三维重建过程中，由于特征提取和匹配时误差的存在，使得不规则物体的精确重建变得非常困难，本文提出了一种利用二次样条曲线作为基元的三维重建方法，并将之应用到空间不规则物体的三维重建中。
