摘要: 钢结构在长期荷载及不均匀受力的作用下会产生空间变形,挠度是其重要的衡量指标。常规挠度检测方法依赖于手动测量或固定传感器,在实时性、精度和覆盖范围等方面存在一定的局限性,难以准确捕捉结构变形的细微变化。本文基于同时定位与地图构建技术(SLAM)三维激光扫描系统对钢结构网架进行顶升测量,以某汽车厂房项目为工程背景,并通过RANSAC算法提取钢结构节点球的球心进行挠度检测。研究表明,基于SLAM技术的钢结构挠度检测方法具有较高的精度和实时性,能够有效地检测出钢结构网架的挠度变形,为钢结构挠度检测提供了一种新的思路和解决方案,具有重要的理论和应用价值。

Abstract: Steel structures will produce spatial deformation under long-term loading and uneven forces, and deflection is an important measure of it. Conventional deflection detection methods rely on manual measurements or fixed sensors, which have certain limitations in real-time, accuracy and coverage, making it difficult to accurately capture the subtle changes in structural deformation. In this paper, the plant project of an automobile is taken as the engineering background, and the 3D laser scanning system based on simultaneous localization and mapping (SLAM) technology is used to carry out jacking measurements on the steel structure mesh frame and extract the spherical centers of the node balls of the steel structure through the RANSAC algorithm for deflection detection. The study shows that the steel structure deflection detection method based on SLAM technology has high accuracy and real-time performance, and can effectively detect the deflection deformation of the steel structure mesh frame, which provides a new idea and solution for steel structure deflection detection, and has important theoretical and application value.

Key words: SLAM, deflection detection, RANSAC, steel structure
