Reality Capture Technologies for Automated Quality Control during Construction 3D Printing
Publication: Computing in Civil Engineering 2023
ABSTRACT
A low-cost 2D LiDAR sensor and a near real-time data processing algorithm are used in this study to capture the as-built geometry of the freshly printed layers for inline and automated inspection. The accuracy of the proposed system is evaluated under different conditions and layer dimensions. Based on the obtained results, significant improvements were observed after a statistical approach was used for outlier detection and elimination. Maximum error values of less than 1.1 mm were achieved for inline layer width and height measurements using the proposed approach.
