摘　　要：阐述了散乱数据点的曲面重构的方法,重构出不同结构物体的三角网表面模型。首先根据扫描点云的分布特点、疏密程度等实际情况,分析影响重构曲面的关键因素,然后按照正向设计的思想,分析零件的外形,发挥不同曲面拟合的优势。结合典型逆向软件Geomagic对曲面造型方式的特点及应用进行研究与分析。进而规划两个零件的重构路径,达到了良好效果,为复杂零件的重构提供了借鉴意义。The surface reconstruction method is introduced,from scattered data points of different models to the triangulation surface.First of all,according to the actual situation of points cloud,such as distribution characteristics and the density,this paper analyzed the key factors,then used the forward design thought,analyzed the shape of parts and took advantage of different ways of fitting surface.This paper researched and analyzed how to model surface,combining with typical reverse software Geomagic.It formulated the ways for reconstruction of two parts,and achieved a good effect,providing guidance for reconstruction of complicated parts.
