Does Head Orientation Influence 3D Facial Imaging? A Study on Accuracy and Precision of Stereophotogrammetric Acquisition.

摘要: This study investigates the reliability and precision of anthropometric measurements collected from 3D images acquired under different conditions head rotation. Various sources error were examined, equivalence between craniofacial data generated alternative positions was assessed. captures a mannequin obtained with stereophotogrammetric system (Face Shape MaxiLine). Image acquisition performed no rotations various pitch, roll, yaw angulations. On images, 14 linear distances measured. indices used to quantify magnitude, among them error, mean maximum intra- inter-operator measurement repeatability reproducibility standard deviation, errors. Two one-sided tests (TOST) assess recorded in The intra-operator very low (0.336 mm), closely followed by (0.496 mm). 0.532 mm, highest degree found (0.890 Anthropometric resulted significantly equivalent TOST, exception Zygion (l)-Tragion (l) Cheek measured pitch angulation compared rotation position. Face Maxiline has sufficient accuracy for orthodontic surgical use. Precision not altered orientation, making simpler constrained critical as 2D photographs.
