Three-dimensional surface imaging: limitations and considerations from the anthropometric perspective.

The use of three-dimensional (3D) surface imaging for clinical measurement purposes has increased considerably as the technology has become more affordable. Like any measurement technique, 3D surface-based anthropometry is subject to a number of limitations and methodological caveats and thus should not be applied without sufficient consideration of its potential strengths and weaknesses. In this brief report, the authors consider 3D surface imaging from the anthropometric perspective, specifically focusing on issues related to the capture of reliable quantitative information from the head and face.
