摘要
分析了Tracker软件研究自由落体实验的过程中,从录制到处理实验视频的每个步骤引入的误差,通过对比传统实验中得到相对误差的方法,研究Tracker软件处理自由落体实验误差的主要来源,逐步总结出一系列使用Tracker处理动态视频时减少误差的方法,并对不同方法处理同一套仪器录制视频的误差进行对比,结果显示,本方法的准确度较高,能够一定程度上提高应用Tracker分析实验结果的精度.
By using Tracker software to analyze every process of physical free falling video from recording to processing experimental video,this paper clearly introduces the errors introduced by each step in the software analysis.Besides,it carries on the error research by comparing the theoretical values and the relative errors caused by traditional method of solving free failing body.So the relative error of the object motion video analyzed by Tracker is obtained.Furthermore,comparing the main sources of the errors,a series of methods are summarized step by step to reduce the large error when using Tracker to process dynamic video.This method is used to deal with videos recorded by a set of instruments.By comparing their errors,it is verified that the accuracy of this method is high.
