In online phase measurement profilometry(PMP),when the which velocity of the the shape object is quite high,error,flaw,the or collected even reformed to fringes often appear to be motion-blurred the images,increases measurement and leads clarify the the 3D reconstruction failure.In online rail,PMP 3D measurement of rail such surface in order to blurred reformed fringes of the several restoration methods,as Wiener were Filtering,compared Point and Spread Function And algorithm,peak Blind to Deconvolution noise algorithm,and for Richardson-Lucy evaluating algorithm analyzed.relationship shape the signal vehicle ratio and(PSNR)is used the the restoration error effect.Meanwhile,the between the speed on the PMP.restoration effect was studied,was show analyzed that and the 3D rail was reconstructed rail based online flaw,Theoretical and experimental algorithm results best in the online 3D of measurement motion of and shape and surface the Richardson-Lucy is the the one for image is restoration blur,the relationship between the effect of image restoration and vehicle speed a polynomial.
