Abstract
The fundamental researches on movement analysis in batting of baseball were conducted by two high speed video cameras and two tn-axial acceleration sensors. The velocity analysis by using the advance setting and the signal processing were clearly shown. The velocities by both two-dimensional analysis and three-dimensional analysis were discussed. The images by DLT method using two high speed video cameras were linked with velocities of bat speed or left hand speed. The significance of three-dimensional analysis was shown by the statistical analysis.
