Abstract
Recently, a number of non-destructive testings equipment (NDTs) which can partially replace human-conducted onsite inspections has been implemented for detecting modern civil architectural structures. However, the situation of implementing 3D laser scanning measurement technology worldwide is not optimistic: several inconvenient flaws is troubling users (e.g., heavy, costly, hard to move, hard to inspect and etc.). Therefore, a new equipment to fix those problems is urgently demanded. This paper aims to thoroughly analyze the issue and then develop a feasible. A 3D laser scanning system composed of high precision elevating platform and small 2D laser ranging sensor is designed. Manufacture Process of 3D laser scanning system is describes in detail. Based on the bending fatigue loading test, the scanning designed efficiency and feasibility had been proved by comparing and analyzing traditional measurement results. The designed 3D laser scanning system can quickly capture the information of micro-damage and depth of the structure. Its detecting performance is better than the traditional methods. To overcome the challenges of the 3D laser scanning on-site measurement technology, this article proposed the manufacture process of the 3D scanning system with a high precision, miniaturization and lightweight.
Highlights
Building structure testing can provide a reliable basis for the quality assessment of engineering structures, the identification of existing structural properties and the verification of structural calculation theory [1]
The measurement results are obtained based on Digital Image Correlation (DIC) technology and the yernier caliper detection method based on traditional detection technology respectively
The 3D laser scanning system developed in this paper realizes the modeling of the measurement structure
Summary
Building structure testing can provide a reliable basis for the quality assessment of engineering structures, the identification of existing structural properties and the verification of structural calculation theory [1]. We can independently design a 3D scanning device that drives the 2D laser sensor to move up and down according to the needs of the detection object and the environment.20]. The stepper motor drives the fine movement of the sliding group to realize the lifting and scanning of the two-dimensional laser ranging sensor.
