【摘要】 算法以稠密采样点模型表面局部区域内的双边滤波函数值为依据,模型表面附近任意一点的函数值通过与该点最近的模型表面的K个采样点数据直接计算得到。与已有的隐式曲面重建方法相比,该方法既不用曲面内部或外部的支撑点,也不用求解线性和非线性方程,其重建速度快。此外,由于采用双边滤波函数作为其重建的隐式曲面的函数值,因此还能对带有噪声的采样点模型进行特征保持的表面重建。实验结果表明,对于稠密采样点模型,该方法可以快速重建出逼近程度高,效果好的曲面。更多还原

【Abstract】 The proposed algorithm uses the local bilateral filter function near the surface of the point model as the surface reconstruction function.The function value at a given position near the model surface can be computed directly by the bilateral filter function of the nearest K-neighbors.Compared with previous methods,this algorithm doesn’t need solve any linear system or non-linear equations and doesn’t need any internal or external support points.In addition,it can handle the noising data and preserve sharp features,since the function is based on a bilateral filter.Experiment results show that it can reconstruct high quality surfaces for complex 3D objects.更多还原
