非接触三维测量中新的相位—高度分析模型
A new model for analyzing phase-height mapping in 3D measurement based on fringe projection
摘要
Abstract
A new phase-to-height mapping algorithm in 3D surface measurement based on nonparallel illumination is proposed.. In this new method,it is not necessary that the connecting-line between the exit pupil of the projecting lens and the entrance pupil of the imaging lens is horizontal and set to parallel to the reference plane. And the projection optical axis and the imaging optical axis can not need to cross at the same point on reference plane. In addition. The nonparallel illumination analysis is coincident with practical system. This method offers a flexible way for us to build the measurement system to obtain the full-field fringes through moving either location of the projector or imaging device. Another advantage of this method is that only one fringe pattern is needed to finish the reconstruction of the 3D surface.关键词
