文章所提出的方法对于利用图像测量回转曲面物体的面积以及划伤、磨损、锈蚀等具有重要的参考价值。 - This process is as follows : firstly , the data of different section contour and of section line have been obtained by reverse - engineering ; secondly , non - uniform b - spline approximation algorithm is used to fit the discrete data ; then the data have been optimized and reduced by adopting adaptive sampling of key points of the fitted curve based on vertical distance , sequently the adaptive sampling data is transformed into the format of the . ibl file of the famous 3 - d design software pro / e . therefore we reconstruct the surface and a model is generated ; lastly , the effectiveness of the adopted algorithm and modeling approach are demonstrated by the experiments
建模型的过程中，首先运用逆向工程测量方法，获得曲面物体上不同截面轮廓线的测量数据点列，接着对测量数据点进行平滑处理，用最小二乘法求解基于数据点列的控制多边形，以非均匀三次b样条曲线拟合截面轮廓曲线；然后利用基于垂距的数据采样算法，对拟合曲线上的数据点进行重新采样，达到优化数据点的分布及减少描述曲线数据量的目的。 - First , by using coordinate rotation , we have discussed the computer - generated hologram composed by planar object whose plane does n ' t run parallel with that of its hologram . second , through coordinate transform , the computer - generated hologram of curvy planar object has been discussed again , in which , conformal map in computer graphics has been creatively applied , and generated the computer - generated hologram of simple curvy plane ( e . g . spherical surface ) ; also , in this section , the correctness of transformation has been confirmed by numerical reconstruction
首先利用坐标旋转讨论不平行于全息面的平面所构成的物体的计算全息图：接着采用坐标变换讨论曲面物体的计算全息图，创造性地将计算机图形学中的共形对应原理运用到计算全息中，生成了简单曲面(如球面)物体的计算全息图，并用数字重现验证了变换的正确性，为今后复杂三维物体的计算全息图的研究奠定基础。
