摘　　要：针对目前逆向工程三角Bezier曲面建模中存在的缺点,介绍两种解决方法:基于三角Bezier曲面模型的逆向工程CAD建模方法和基于局部三角Bezier曲面片逼近的点插补算法。通过这两种方法解决了所构造的曲面模型与现有的CAD/CAM软件系统接口难等问题,使得三角Bezier曲面建模变得切实可行。About the faults of modeling of triangular Bezier surface in reverse engineering, introduces two kinds of methods：the method of reverse engineering CAD modeling which based on the model of triangular Bezier surface and an algorithm for interpolation of points based on local approximation of triangular Bezier patch. These two kinds of methods resolved many problems in modeling and make it feasible to build the model of triangular Bezier surface.
