Abstract: This paper introduces the design and implementation of an automatic processing software system for LAMOST celestial spectra. Some key algorithms in the system such as covering algorithm, wavelet transform, mean shift, etc., are also presented. The experiment results over the datasets of sloan digital sky survey (SDSS) show that this system has good characters in processing speed, classifying accuracy and redshift measuring precision. And the implemented system is workable for the large survey projects.
