摘要:

3D模型广泛应用于各行各业,因其独特的优势,网格数据已成为3D建模不可或缺的一部分。网格数据能够提供丰富3D信息的直观且实用的表达。然而,其无序、不规则的数据结构以及复杂的表面信息,使得直接将其应用于深度学习模型极具挑战性。传统的网格数据处理方法通常依赖于带有诸多限制(例如流形限制)的网格模型,这限制了其在现实中的应用范围,且未能充分利用网格模型的优势。本文提出了一种以图神经网络(GNN)为中心的、用于解决网格模型深度学习相关挑战的新型端到端框架,命名为InfoGNN。InfoGNN将网格模型视为一个图,使其能够高效处理不规则的网格数据。此外,我们提出了InfoConv和InfoMP模块,这些模块利用了点的位置信息,并充分利用了面法线、二面角等静态信息以及动态全局特征信息,从而充分利用各类数据。此外,InfoGNN是一个端到端框架,我们简化了网络设计以提高其效率,为复杂3D模型的高效深度学习铺平了道路。我们在几个公开可用的数据集上进行了实验,结果表明InfoGNN在网格分类和分割任务中取得了优异的性能。

英文摘要:

3D models are widely used in various industries, and mesh data has become an indispensable part of 3D modeling because of its unique advantages. Mesh data can provide an intuitive and practical expression of rich 3D information. However, its disordered, irregular data structure and complex surface information make it challenging to apply with deep learning models directly. Traditional mesh data processing methods often rely on mesh models with many limitations, such as manifold, which restrict their application scopes in reality and do not fully utilize the advantages of mesh models. This paper proposes a novel end-to-end framework for addressing the challenges associated with deep learning in mesh models centered around graph neural networks (GNN) and is titled InfoGNN. InfoGNN treats the mesh model as a graph, which enables it to handle irregular mesh data efficiently. Moreover, we propose InfoConv and InfoMP modules, which utilize the position information of the points and fully use the static information such as face normals, dihedral angles, and dynamic global feature information to fully use all kinds of data. In addition, InfoGNN is an end-to-end framework, and we simplify the network design to make it more efficient, paving the way for efficient deep learning of complex 3D models. We conducted experiments on several publicly available datasets, and the results show that InfoGNN achieves excellent performance in mesh classification and segmentation tasks.
