砌体结构的数值模型的生成是一个及时和昂贵的过程,因为它需要大量的小颗粒的离散化。同样,传统的目视检查涉及对砌体结构上的每个元素的谨慎考虑。在这两种情况下,每个砖元素都需要单独考虑。本文档中介绍的工作旨在缓解使用计算机视觉和卷积神经网络(CNN)记录单个砌体单元和结构裂缝所产生的问题。特别是,第一次开发了一个动态的工作流程,其中自动检测砌体结构中的砌体单元和裂缝,并用于开发一个完整的几何数字双胞胎。其结果是一个集合的空间坐标和几何对象,代表砌体结构实体,并允许文件和结构评估的对象的理解。建筑、结构和结构分析模型之间的这种互操作性为使用工程为我们现有的基础设施创造更智能、更安全、更可持续的未来铺平了道路。
The generation of numerical models for masonry structures is a timely and costly procedure since it requires the discretization of a large quantity of smaller particles. Similarly, traditional visual inspection involves the cautious consideration of each element on a masonry construction. In both cases, each brick element needs to be considered individually. The work presented in this document aims to alleviate the issues arising from documenting individual masonry units and cracks on a structure using computer vision and convolutional neural networks (CNN). In particular, for the first time a dynamic workflow has been developed in which masonry units and cracks in masonry structures are automatically detected and used for the development of a complete geometric digital twin. The outcome is a collection of space coordinates and geometrical objects that represent the masonry fabric entity and allow the comprehension of the object for documentation and structural assessment. This interoperability between architectural, structural, and structural analysis models paves the way to use engineering to create a smarter, safer, and more sustainable future for our existing infrastructures.
