The first system–V-STARS INCA3 from Geodetic Systems Inc. – is a commercially available measurement solution. The second system comprises an off-the-shelf Nikon D700 digital camera fitted with a 28 mm Nikkor lens and the research-based Vision Measurement Software (VMS). The uncertainty estimate of these two systems is determined with reference to a calibrated constellation of points determined by a Leica AT401 laser tracker. The calibrated points have an average associated standard uncertainty of 12.4 µm, spanning a maximum distance of approximately 14.5 m. Subsequently, the two systems’ uncertainty was determined. V-STARS INCA3 had an estimated standard uncertainty of 43.1 lm, thus outperforming its manufacturer’s specification; the D700/VMS combination achieved a standard uncertainty of 187 µm.
