抄録

This paper describes an automatic decidable method of absolute sequence numbers of fringes that have been thought as the complicated problems in the automatic 3-dimensional measurement system with moiré topography. In the method, a system of the scanning moiré topography is constituted theoretically with two TV-cameras and a projector. By comparing with two pictures generated by two TV-cameras, the original fringe can be extracted logically in the picture. Then, absolute sequence number of original fringe becomes zero. Furthermore, with this result and the relative sequence numbers of fringes given by uphill or downhill judgement, the absolute sequence numbers of fringes can be determined automatically with regard to every fringe. The results show that the method is useful for the complex configuration. It may be concluded that the method accelerates the progress of the automatic 3-dimensional measurement system with moiré topography.
