Outcomes Module

Primary Outcomes

Measure	Description	Time Frame
Accuracy of Photogrammetry in Generating 3D Facial Models - Linear Measurements	A 3D model was generated for each volunteer using photogrammetry software. Anthropometric linear measurements was taken using a digital caliper, and photogrammetric linear measurements was extracted from the 3D model. Two LEGO® blocks with uniform dimensions were attached to the participants' faces to scale the 3D model to actual metric dimensions. Unit of Measure: millimeters(mm)	Baseline (procedure)
Accuracy of Photogrammetry in Generating 3D Facial Models - Angular Measurements	This outcome measure focuses on the accuracy of photogrammetry in capturing and reproducing angular measurements of facial features. Volunteers' 3D facial models were generated using photogrammetry software from multiple photos. Two LEGO® blocks with uniform dimensions were attached to the forehead and cheek for scaling and reference. Angular measurements, based on these blocks, were extracted from the 3D model. The measurements were compared to validate the method's precision in reproducing angular dimensions. Unit of Measure: Degrees (°)	Baseline (procedure)
