Abstract: NURBS surface reconstruction is discussed from the two aspects of smooth surface and precision. Given the test whether surface is smooth. To the not smooth surface, by using modified point, section feature curve to improve the surface smoothness. Surface reconstruction accuracy does not meet the requirements of the situation, using the modified method of control vertices to correct surface reconstruction error. This paper provides a method for the reconstruction of surfaces effective assessment and correction.


Keywords: Surface reconstruction, Smoothing assessment, Accuracy correction, Reverse engineering.
