Research on a Dynamic Calibration Method for Photogrammetry Based on Rotary Motion

Photogrammetry as an engineering measurement technology for the rapid and non-contact acquisition of geometric parameters, such attitude, position, shape a measured object, is widely used in development production processes aerospace automobile industries. The calibration corresponding photogrammetry system basis ensuring accuracy photogrammetry. dynamic static existing systems has not yet established specification or standard, mainly focused on internal external parameters camera system. cannot fully guarantee performance process measuring targets micro-deformations. Aiming at problem parameter systems, this paper proposes method based circular trajectory standard device, which can realize length error, ensure accurate evaluation systems.
