Structured-light three-dimensional scanning for process monitoring and quality control in precast concrete production.


This paper presents the use of a structured-light three-dimensional scanner to allow for efficient and real-time inspections of precast concrete specimens. This proposed quality assurance system reviews the quality of a product in three key features: overall dimensions, embedded locations, and surface finishes. The experimental program demonstrated that the proposed quality assurance system can quantitatively measure the surface finish of a precast concrete object, recognize and check the location of the embedded metal parts, and validate the overall geometry with the design.
