Guidelines and Standards for Calibrated Millimeter Accurate Measurements in 3D Body Scans



botspot AG, Berlin, Germany


By applying standard precision measurement techniques from the surveying industry, we demonstrate a process for calibrating the measurement accuracy in the millimeter range on a photogrammetry-based 3D model of humans. The two key elements behind a successful and truthful calibration baseline are:

1) Trust your measurement (which is we apply measurement standards from the surveying industry)
2) Control your space (the design aspects of the scanner space that optimize the calibration techniques)

This calibration method was applied to a commercial 3D body scanner and then verified using externally and independently calibrated scale bars. After calibrating the body scanner, a statistical comparison of measurements on mesh-based 3D models from humans pre- and post-calibration was performed.

Based on these results, a new calibration hardware optimized for photogrammetry-based body scans was developed to ease the open question of calibrated measurement accuracy on-site at the end customer's facilities.
