Abstract
With the use of 3D body scanners, body measurement techniques can be non‐contact, instant, and accurate. However, how each scanner establishes landmarks and takes the measurements should be established so that standardization of the data capture can be realized. The purpose of this study was to compare body‐scanning measurement extraction methods and terminology with traditional anthropometric methods. A total of 21 measurements were chosen as being critical to the design of well‐fitting garments. Current body scanners were analyzed for availability of information, willingness of company cooperation, and relevance to applications in the apparel industry. On each of the 21 measurements, standard measurement procedure was identified for three different scanners: [TC]2, Cyberware, and SYMCAD. Of the 21 measures in the study, [TC]2 was the scanner that had the most measures identified for the study and also had the capability of producing many more with specific application for apparel.

Investigate 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.
Abstract
Purpose
Investigate 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/approach
Discusses 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.
Findings
Presents 3D reconstructions of objects from each of the commercial systems.
Research limitations/implications
Provides 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 implications
Imaging‐based approaches to 3D model generation offer potential to increase scanning time and reduce scanning complexity.
Originality/value
Introduces imaging‐based concepts to the rapid prototyping pipeline.

Abstract
Purpose
This paper seeks to describe an innovative new technology for digitizing the shapes of 3D objects quickly and accurately, which uses accordion fringe interferometry (AFI).
Design/methodology/approach
Laser beams cast fringe patterns on objects, a digital camera captures images and software constructs point clouds of data. A software package then analyzes the point cloud to extract information such as dimensions or variations in shape for subsequent operations.
Findings
The AFI approach has already been applied to a number of applications such as: inspection of jet engine airfoils, repair of composite structures and inspection of very delicate objects.
Practical implications
Point cloud digital shape scanning will find an ever increasing number of applications which will benefit from this fast, accurate and non‐contact three‐dimensional digitizing technology.
Originality/value
Users now have a totally new means for capturing dense, three‐dimensional data.

Abstract
Discusses the 6th ITCRR, its breadth of textile and clothing research activity, plus the encouragement given to workers in this field and its related areas. States that, within the newer research areas under the microscope of the community involved, technical textiles focuses on new, ‘smart’ garments and the initiatives in this field in both the UK and the international community at large. Covers this subject at length.

Abstract
This paper presents the design and validation of a universal 6D seam tracking system that reduces the need of accurate robot trajectory programming and geometrical databases in robotic laser scanning. The 6D seam tracking system was developed in the flexible unified simulation environment, integrating software prototyping with mechanical virtual prototyping, based on physical experiments. The validation experiments showed that this system was both robust and reliable and should be able to manage a radius of curvature less than 200 mm. In the pre‐scanning mode, a radius of curvature down to 2 mm was managed for pipe intersections at 3 scans/mm, using a laser scanner with an accuracy of 0.015 mm.
