  The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST)
project performed its five year formal survey since Sep. 2012, already
fulfilled the pilot survey and the 1st two years general survey with an output
- spectroscopic data archive containing about 3.5 million observations. One of
the scientific objectives of the project is for better understanding the
structure and evolution of the Milky Way. Thus, credible derivation of the
physical properties of the stars plays a key role for the exploration. We
developed and implemented the LAMOST stellar parameter pipeline (LASP) which
can automatically determine the fundamental stellar atmospheric parameters
(effective temperature Teff, surface gravity log g, metallicity [Fe/H], radial
velocity Vr) for late A, FGK type stars observed during the survey. An overview
of the LASP, including the strategy, the algorithm and the process is presented
in this work.
