摘　　要：由于标枪运行过程中是一个多轴性旋转体,针对标枪运动中标枪运动轨迹测量的难题,该文提出利用3轴运动传感器mpu6050来测量标枪的空中运行轨迹。该文首先给出了对标枪运动的公式进行推导,接着给出了标枪轨迹测绘仪的硬件原理框图,最后给出了软件实现流程图和实际测量的标枪飞行过程中的俯仰角测试结果。该标枪轨迹测绘仪在训练和教学中有良好的使用前景。Aimed at to solve the challenge of measure javelin trajectory,due to the flight process of Javelin is a multi-axial rotator.The paper proposes to take advantage of the three-axial motion sensor(mpu6050)to measure the javelin trajectory in the sky.Firstly,the thesisdeducted the formula on the Javelin movement.Nest the hardware functional block diagram for measuring theJavelintrajectory was offered.Last the paper show software flow chart and the javelin trajectory measure results which are linked to the actual measurement of the angle of pitch.The javelin trajectory measuring instrument has a good prospect in training and teaching process.
