Abstract

The paper presents a combination calibration method of digital cameras based on the ten-parameter model and the finite element model. The predictable distortion errors can be compensated with the ten-parameter model while the unpredictable ones compensated with the finite element model. A calibration experiment has been carried out on the metric camera Inca3 and non-metric cameras Canon 5D Mark II and Nikon D2H. The measurement accuracy of the metric camera with steady framework can be improved effectively. The accuracy of the non-metric cameras can be improved indistinctively due to their unsteady framework.
