基于相移条纹投影的动态3D测量误差补偿技术
Dynamic 3D measurement error compensation technology based on phase-shifting and fringe projection
摘要
Abstract
In the process of dynamic 3D measurement based on phase-shifting and fringe projection,the ideal correspondence between object points,image points and phases in different fringe images is destroyed.On this condition,the application of traditional phase formulas will cause significant measurement errors.In or-der to reduce the dynamic 3D measurement error,the basic principle of the error is firstly analyzed,and the errors are equivalent to the phase-shifting errors between different fringe images.Then,a dynamic 3D meas-urement error compensation method is proposed,and this method combines the advanced iterative algorithm based on least squares and the improved Fourier assisted phase-shifting method to realize the high-precision calculation of random step-size phase-shifting and phase.The actual measurement results of a precision ground aluminum plate show that the dynamic 3D measurement error compensation technology can reduce the mean square errors of dynamic 3D measurement by more than one order of magnitude,and the dynamic 3D measurement accuracy after compensation can be better than 0.15mm.关键词
