Abstract

The accuracy is important for a 3D whole body scanning system. In order to analyze the measurement error, a set of dimension-certified measurement equipment whose true dimensions were certified was introduced. The calibration models of height, breadth and depth measurement between measured values and true dimensions were established respectively and relevant error envelopes were derived. A verification experiment was conducted to determine the validity of these models. The accuracy of this scanning system can be improved by using the calibration models to obtain more accurate 3D human models.
