System and method for mapping and calibrating training javelins

The invention provides a system and a method for mapping and calibrating training javelins. The system comprises mapping instruments and a mapping and calibrating mechanism. Each mapping instrument comprises a CPU (central processing unit), a battery, a six-axis movement sensor, a calibrating button and the like, each battery is connected with the corresponding CPU and is powered by the CPU, each CPU is connected with the corresponding six-axis movement sensor, and calibrating keys which are matched with the mapping instruments are arranged on javelin bodies; the mapping and calibrating mechanism comprises a tilt angle sensor and a calibrating device support, the javelin bodies are arranged on the calibrating device support, level adjusting bolts are arranged at the bottom of the calibrating device support, a parallel plate is arranged on the top of the calibrating device support, and the tilt angle sensor is mounted on the parallel plate. The system and the method have the advantages that movement tracks and parameters capable of affecting throwing distances can be accurately and reliably acquired in real time, accordingly, training effects can be improved, and the system and the method have excellent actual use and popularization value.
