typical motion characteristics. In this paper，the motion equation of the spring pendulum system is
obtained through the theoretical analysis of the Lagrangian equation，and the motion is
decomposed in the radial and tangential directions. The spring pendulum demonstrator and
experimental software are designed by using image processing technology to visu- alize the motion
track and time sequence diagram The trajectory drawn by the software is in good agreement with the
theoretical results.
Key words： spring pendulum; image processing; Lagrange equations
