Automated Visual Inspection Planning for Prefabricated Modules with 3D Laser Scanning
Modular construction offers an effective solution to schedule and quality problems in construction. However, if a defect on a module is identified on-site, it can easily cause problems and rework, leading to additional delays and cost overrun due to long lead time. Therefore, quality assessment of modular components is very important. There were many efforts to leverage 3D laser scanners (i.e., terrestrial) for inspection of building structures. These studies aimed at optimizing scanning locations while ensuring detailed scanning of the whole buildings. However, there was little to no research on leveraging 3D laser scanners for modular components that require scanning from the surrounding views. Therefore, this paper proposes a scan planning method that generates and optimizes scan locations for prefabricated components. The presented method creates the geometric relationship between the 3D BIM/CAD and the scanner’s properties (i.e., angular step, range, and field of view) to assess visibility and quality while evaluating best and optimal scan positions. The experimental results show that the proposed method can generate scan positions that meet the user requirement to the extent scanning is geometrically possible.
