Photogrammetry with a single camera is preferably chosen as contactless method for the pose measurement of a novel 6-Degree-of-Freedom (DOF) platform prototype. Application research on photogrammetry technique and background of the measurement are briefly reviewed. Camera calibration theory and specific calibration method implemented during the measurement are described. A CAD model of the prototype is built to simulate ideal displacements of its 6 DOFs, which are then compared with the measured data to figure out measurement error. The error sources are preliminarily investigated. The prospects of the application of photogrammetry with a single camera are commented.
