Evaluation of cap design for 3D scan

Abstract

The 3D human anthropometry study has become more and more popular in design area. Human body shape can be captured by 3D scanner and surface data can be collected for further analysis. However, accuracy of the scanned data can be affected by the participant’s hair, especially during head scans. A cap is normally used to compress the hair. Depending on the hairstyle and the cap design, the data at the ear region, the neck region and the top region of the head can be missing or wrong. In this study, we demonstrated the problems caused by the hairstyle and the cap design using 3D head scanners. The results indicated that a new cap design for 3D head scanning is needed in order to collect better data.
