Description

Technical Field

[0002] The dimensional accuracy of steel structures is essential to ensure the stability, functionality and durability of the structure. Accurate dimensions ensure the close fit of structural elements, helping to reduce stress concentration and the risk of structural instability. Traditional manual dimensional measurement methods have problems such as time consumption, subjectivity and errors. In large-scale projects, these problems may lead to inconsistent measurements and limited project progress. Laser scanning technology is valued for its non-contact, high accuracy and high efficiency. Through the scanning of the laser beam, the three-dimensional point cloud data of the component can be captured, providing an accurate basis for size and shape analysis;

[0003] Traditionally, engineers would use tools (such as tape measures and measuring calipers) to manually measure the various dimensions of steel structures for the inspection of steel structure components. This requires a lot of time and manpower and is susceptible to human error. During the manual measurement process, engineers would mark and record the dimensional data of each component. These data may need to be manually entered into a computer or file, which poses a risk of data entry errors. Similarly, manual inspection of the surface and interior of components to detect possible defects, such as cracks and corrosion, requires judgment and classification of defects, which is subjective. Ultimately, engineers generate reports based on manual measurement data and analysis results, detailing the dimensions and defects, which may require additional time and resources.
