Abstract

This paper compares two kinds of cylinder stitching algorithm: global error homogenization stitching algorithm and Legendre Fourier polynomial fitting algorithm. The former uses the overlapping regions between adjacent sub-apertures, which can obtain high accurate results but need more time on data acquisition; Legendre-Fourier polynomial fitting stitching algorithm without overlapping regions need less aperture and short measure time but lack of high frequency information. Its stitching results easily affected by the position error of sub aperture, which is more suitable for in-situ measurement.
