Abstract
MacKinnon's 2009 talk asked for a structural-resolution metric that was independently verifiable and metrologically traceable; this is the answer built. The National Research Council developed a portable target case for short-range triangulation-based 3D imaging systems working between 10 cm and 3 m standoff – a set of low-cost calibrated artefacts with a matching series of test procedures. The best-practice procedures were deliberately chosen to be practical, simple to perform and easy to understand, and use GD&T terminology wherever possible. Within-cell repeatability and bias analysis can be performed for appropriate characteristic values, and between-cell scenario testing alongside it.
