新方法为点云计算快速逐点符号距离

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员开发了一种计算点云符号距离的新颖方法，能够快速、高分辨率地评估近似底层表面。该技术涉及使用圆环体局部拟合点云，圆环体具有闭式符号距离函数，并使用预训练网络确定每点曲率和偏移参数。该方法绕过了昂贵的全局优化和空间离散化，提供了一个将符号距离与缠绕数和泊松表面重建统一起来的新理论框架。它可以应用于来自各种来源的点云，包括摄影测量和神经隐式，允许直接用于形态学操作和可视化等应用。 AI

影响 这种新的点云处理方法可以加速3D重建和可视化领域的应用。

    Points as Tori: Fast Pointwise Signed Distance for Point Clouds

    arXiv:2607.16946v1 Announce Type: cross Abstract: We describe a method for computing signed distance to point clouds that allows fast pointwise evaluation at arbitrary spatial resolution. As input, our method takes a point cloud with normals; as output, it provides an analytical …
