The polarization state of inhomogeneous complex polarized beam is hard to describe and detect. A point-to-point polarized light measuring method is proposed which can get the polarization of all the points in the cross section in one detection and provide enough information describing inhomogeneous polarized beam, especially describing radically and azimuthally polarized beams. Detecting known polarized beams with this method, good results are obtained, which demonstrate the point-to-point method stable and reliable to detect the cylindrical vector beams. Parameters used to depict the uniformity of cylindrical polarization beams are also redefined, which provide the quantitative indexes supporting the measurement of cylindrical polarization beams.
