基于三角Bézier曲面片逼近的汽车覆盖件曲面重构

Surface Reconstruction of Auto Panel Based on Triangular Bézier Surface Approximation Approach

以非接触式三坐标激光测量仪所得到的实物曲面散乱数据点为基础,给出了一种用三角Bézier曲面片逼近法来重构曲面、重构汽车覆盖件曲面的方法。该方法对优化的三角网格模型进行逼近时,可以获得精度和光顺性都较好的重构曲面。

Based on the unorganized points of material object surface got by a 3D untouched laser scanner,this paper de- scribes a method for reconstructing auto panel surfaces from unorganized points with triangular Bézier surface approxima- tion approach.When the triangular model is an optimized,an restructured surface with good precision and smoothness can be obtained with this method.
