  • Online:2012-04-25 Published:2012-04-20

摘要: 在落球法测量液体黏度中利用Tracker视频分析软件捕捉分析小球下落轨迹,减小了实验中诸多不确定因素带来的测量误差,使数据处理更为直观、准确.结果表明此方法能准确测量小球的收尾速度,而且可以对现有实验内容进行扩展.

关键词: Tracker软件, 视频分析, 落球法, 液体黏度

Abstract: Software tracker is applied in measuring the viscosity coefficient of liquid oil by dropping ball.By video capture and motion analyze function build in tracker,the trajectory of the falling ball is obtained.Experimental uncertainty lurking in the traditional measuring process is revealed and analyzed.The motion and data analysis by tracker are accurate and visual.The results show that the tracker is capable in exploring more complicated motion of fluid.

Key words: software tracker, motion capture, falling ball, viscosity coefficient of liquid
