Abstract

Shadow always appears on the captured fringe images in traditional fringe projection profilemtry system. To recover the shadow area, in existing methods, fringe patterns from multiple projectors are employed to calculate the absolute phase maps of entire object surface. However, if the fringe order errors in the absolute phase maps were not corrected, significant errors would appear on the reconstructed three-dimensional result. In this paper we propose a method to recover the entire surface profile with the fringe projections from two projectors. In the proposed method, the shadow areas are identified, a novel technique is developed to correct the fringe order errors in the absolute phase maps of the fringe patterns from two projectors, thus the reliability of shadow area recovery could be improved. This method also can be used for various applications in industries and academics. The methodology is exemplified with experimental data.
