| Abstract: | One processing method,based on the two dimension(2D) Paul continuous wavelet transformation(CWT),is presented in this paper for three dimension(3D) profile measurement in structure light system.Comparing with two-dimensional Morlet wavelet,the performance of this algorithm is well while the height of the 3D object change quickly,and this case is hard to solve with other method.The error of the 3D profile measurement can be reduced and the measuring precision is improved when the method is used. |
