Abstract This paper presents the methods that have participated in the SHREC’20 contest on retrieval of surface patches with similar geometric reliefs and the analysis of their performance over the benchmark created for this challenge. The goal of the context is to verify the possibility of retrieving 3D models only based on the reliefs that are present on their surface and to compare methods that are suitable for this task. This problem is related to many real world applications, such as the classification of cultural heritage goods or the analysis of different materials. To address this challenge, it is necessary to characterize the local ”geometric pattern” information, possibly forgetting model size and bending. Seven groups participated in this contest and twenty runs were submitted for evaluation. The performances of the methods reveal that good results are achieved with a number of techniques that use different approaches.

SHREC'20 轨道：检索具有相似几何浮雕的数字表面

摘要 本文介绍了参加 SHREC'20 竞赛的方法，该竞赛关于检索具有相似几何浮雕的表面补丁，并分析了它们在为该挑战创建的基准上的性能。上下文的目标是验证仅基于表面浮雕检索 3D 模型的可能性，并比较适合此任务的方法。这个问题与许多现实世界的应用有关，例如文化遗产商品的分类或不同材料的分析。为了应对这一挑战，有必要表征局部“几何图案”信息，可能会忘记模型尺寸和弯曲。七个小组参加了这次比赛，并提交了二十个运行进行评估。
