Abstract

Digital transformation is employed to create digital models that reflect the current state of infrastructure. Conventional semantic structure from motion methods effectively generated digital models of bridges segmented by components through semantic segmentation. However, these methods encounter significant challenges in the digital transformation of pedestrian suspension bridges: the inaccurate modeling of cables due to the inherent limitations of raster data in representing cables. To address these issues, this paper proposes a hybrid semantic structure from motion framework for pedestrian suspension bridges by integrating segmented cables in vector format with other raster format data. The performance of the proposed system was validated through full-scale experiments on a pedestrian suspension bridge in South Korea, achieving a 26.49% improvement in accuracy compared to conventional methods. By automating key aspects of digital transformation, the proposed framework is expected to provide solutions for the management of bridge infrastructure, enhancing safety and operational resilience.

基于运动混合语义结构的行人悬索桥自动数字化转换

数字化转型用于创建反映基础设施当前状态的数字模型。传统的运动语义结构方法通过语义分割，有效地生成了构件分割桥梁的数字模型。然而，这些方法在人行悬索桥的数字化改造中遇到了重大挑战：由于栅格数据在表示电缆时的固有局限性，导致电缆建模不准确。为了解决这些问题，本文提出了一种行人悬索桥运动框架的混合语义结构，通过将矢量格式的分段电缆与其他栅格格式数据集成。通过在韩国一座人行悬索桥上进行的全尺寸实验，该系统的性能得到了验证，与传统方法相比，准确率提高了26.49%。通过自动化数字化转型的关键方面，拟议的框架有望为桥梁基础设施的管理提供解决方案，提高安全性和运营弹性。
