Reliability and Accuracy of 2D Photogrammetry: A Comparison With Direct Measurement.

ABSTRACT:

Objective

Facial anthropometric data is important for the design of respirators. Two-dimensional (2D) photogrammetry has replaced direct anthropometric method, but the reliability and accuracy of 2D photogrammetry has not been quantified. This study aimed to assess inter-rater reliability of 2D photogrammetry and to examine the reliability and accuracy of 2D photogrammetry with direct measurement.

Design

A cross-sectional study.

Setting

Malaysia.

Participants

A subset of 96 participants aged 18 and above.

Primary and secondary outcomes

Ten facial dimensions were measured using direct measurement and 2D photogrammetry. An assessment of inter-rater reliability was performed using intra-class correlation (ICC) of the 2D images. In addition, ICC and Bland-Al
