Bezier and nurbs are chosen as the fundamental method to achieve surface reconstruction on the basis of fundamental theory of sculpture surface reconstruction . then the fitting method of bezier and nurbs surface reconstruction is given after the reconstruction algorism is discussed 作者研究了复杂曲面重建的基本理论，选择b zier和nurbs作为曲面重建的基本方法，同时对曲面重建的算法进行研究，给出b zier和nurbs曲面拟合的不同方法，并对求交、拼接和光顺等方法进行了深入研究。
