A Method of Comparing 3-D Image Consistency and Quality Between Commercially Available 3-D Scanners 2003-01-2177
With a number of 3-D scanners now available commercially, little work has been done to directly compare their capabilities. This study was designed to characterize differences between the Vitronic Vitus Pro scanner owned by TNO in the Netherlands and the Cyberware WB4 scanner owned by AFRL/HECP at Wright-Patterson Air Force Base. For the purpose of the study, the Cyberware scanner was transported to the TNO facility in the Netherlands. Ten male and ten female subjects were scanned three times in each of three poses in both scanners. All scans for a subject were taken in one session. 3-D image data were segmented, aligned and compared using a difference mapping algorithm. The Cyberware scanner yielded useable data for all twenty subjects; however, the scans from the Vitronics scanner were of higher resolution. This method can be used to compare scanners or poses.
