AR Glulam: Accurate Augmented Reality Using Multiple Fiducial Markers for Glulam Fabrication
This addresses the precision limitation for AR adoption in industries like construction and fabrication, though it appears incremental as it extends a lab-validated method to a real-world factory.
The paper tackles the problem of low precision in augmented reality for industrial fabrication by using multiple fiducial markers, achieving a precision of 0.97 in lab settings and applying it to glulam beam manufacturing with tolerances under 2mm in a factory setting.
Recent advancements in Augmented Reality (AR) have demonstrated applications in architecture, design, and fabrication. Compared to conventional 2D construction drawings, AR can be used to superimpose contextual instructions, display 3D spatial information and enable on-site engagement. Despite the potential of AR, the widespread adoption of the technology in the industry is limited by its precision. Precision is important for projects requiring strict construction tolerances, design fidelity, and fabrication feedback. For example, the manufacturing of glulam beams requires tolerances of less than 2mm. The goal of this project is to explore the industrial application of using multiple fiducial markers for high-precision AR fabrication. While the method has been validated in lab settings with a precision of 0.97, this paper focuses on fabricating glulam beams in a factory setting with an industry manufacturer, Unalam Factory.
