Abstract

The fringe projection technology is widely used in 3D measurement fields. However when the technology is applying to translucent objects, the subsurface scattering and absorbing always leads to a decline of the measurement accuracy. The aim of this paper is to propose a dual-direction fringe projection method in order to obtain an more accurate measurement result for the translucent objects as while as change the whole measurement system little and do not reduce the measuring rapidity. The paper mainly includes three parts: (1) The principle of dual-direction fringe projection method and different forms of dual-direction fringe; (2) Analysis of the different effect for the measurement accuracy brought by different factors; (3) Experiments for artificial tooth by various dual-direction fringes and accuracy analysis. The experiment results showed that by this method it is possible to improve the measurement accuracy for the translucent objects.
