反求工程自由曲面测量规划以及重建技术研究

Surface’s measurement in RE is following an important principle that the density of substracted data points should be varied in accordance with the change of surface’s curvature. This paper presents a surface measuring plan which bases on the delamination at the Z coordinate and it also presents a new technology for the NURBS surface fit function. It can obtained the least number of points to reflect free surface. This technology can ensure the function’s quality and it can be applied in all cases of surface’s measurement and reconstrction.
