本文提出了一种改进的α形状由散乱样本点重建分段线性曲面的算法。α-Shape为一组点提供了一个很好的数学定义，但Alpha值的选择在曲面重建中很棘手。为了解决这个问题和分布不均匀的问题，我们根据点的密度对α球进行了缩放。本文所讨论的方法可以应用于曲面重建，并且整个过程是全自动的。
In this paper, we present an algorithm for the reconstruction of piecewise linear surfaces from unorganized sample points with an improved α-shape. Alpha-shape provides a nice mathematical definition of the “shape” of a set of points, but the selection of an α value is tricky in surface reconstruction. F or solving this problem and the non-uniform distribution, we scale the α ball according to the point’s density. The method discussed in this paper might be applied for surface reconstruction, and the process is fully automatic.
