| Abstract: | 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. |
