Abstract
A new methodology for the determination and correction of lens distortion in fringe projection systems for 3D object measurement is introduced. The calibration of the distortion is performed in the device ready for measurement based on the simultaneous determination of both projector and (remaining) camera distortion. The application of the algorithm allows a reduction of distortion errors up to 0.02 pixels in the projector chip and also in the camera chip.
