Photogrammetric 3D digitization of the human head

Abstract

The paper deals with the use of photogrammetry in the digitization of living objects, specifically it is focused on creating a 3D model of the human head by the walk-around method with the using 1 camera. The RealityCapture software (CapturingReality, Slovakia) was used to create the digital model, the output of which is a head model with a realistic texture with sufficient details. Using the GOM Suite 2019 software (Carl Zeiss, Germany), selected anthropometric measurements of the model were carried out before comparing them with those obtained using traditional measurement of a living subject, which we considered the reference. According to the results, the obtained head model contains sufficient details (face surface, texture). The results show that the values obtained from the 3D model differ from the reference values from 0.1 to 1.8 mm with average value 0.637 mm and standard deviation 0.471 mm. The differences between physical measurement and 3D model are lower than 2 mm. Photogrammetry is applicable for field of anthropometry, medicine, technical orthopedy and other, because the results of measurement do not differ significantly from the reference measurements.
