Figure Lengend Snippet: Flowchart summarizing the study’s methodology: 3D data acquisition, 3D data processing, and measurements. The study involved SM generation using three methods: (1) the iPhone 14 Pro’s “3D-Scanner App” V2.1.2 in “Photo-Mode” (2) stereophotogrammetry with the Vectra M5, and (3) the iPhone 14 Pro’s “3D-Scanner App” V2.1.2 in “TrueDepth-Mode”. Data processing steps included extraction of facial areas of interest (FAOIs), scaling and rough alignment via CloudCompare’s ICP-Algorithm, and superimposition and precise alignment via Vectra Analysis Module (VAM) for SM comparison. Measurements included landmark-to-landmark distances and volumetric analyses for the upper face, mid-, and lower face regions utilizing the VAM
Article Snippet: Facial surface models (SMs) were generated for 30 volunteers (15 men, 15 women) using the Vectra M5 ( Canfield Scientific, USA ), the TrueDepth camera of the iPhone 14 Pro ( Apple Inc., USA ), and the iPhone 14 Pro with photogrammetry.
