This paper determines the capability of two photogrammetric systems in terms of their measurement uncertainty in an industrial context. The first system – V‐ STARS inca 3 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 AT 401 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 inca 3 had an estimated standard uncertainty of 43·1 μm, thus outperforming its manufacturer's specification; the D700/ VMS combination achieved a standard uncertainty of 187 μm.
