Abstract
PurposeInvestigate the use of two imaging‐based methods – coded pattern projection and laser‐based triangulation – to generate 3D models as input to a rapid prototyping pipeline.Design/methodology/approachDiscusses structured lighting technologies as suitable imaging‐based methods. Two approaches, coded‐pattern projection and laser‐based triangulation, are specifically identified and discussed in detail. Two commercial systems are used to generate experimental results. These systems include the Genex Technologies 3D FaceCam and the Integrated Vision Products Ranger System.FindingsPresents 3D reconstructions of objects from each of the commercial systems.Research limitations/implicationsProvides background in imaging‐based methods for 3D data collection and model generation. A practical limitation is that imaging‐based systems do not currently meet accuracy requirements, but continued improvements in imaging systems will minimize this limitation.Practical implicationsImaging‐based approaches to 3D model generation offer potential to increase scanning time and reduce scanning complexity.Originality/valueIntroduces imaging‐based concepts to the rapid prototyping pipeline.
