Abstract
A new self-calibration method for a fringe-projection based 3D measurement system is proposed. To determine homologous points in the proposed camera/projector configuration, the phase map is converted to the u, v coordinates in the projected image. The projector can conceptually be regarded as camera acting in a reversed mode. Taking the epipolar constraint into account, this approach can allow self-calibration of the fringe projection system. Considering the effect of noise, we propose a nonlinear self-calibrating model. The experimental results show the effectiveness of this approach.
