基于Kinovea软件的视频车速计算方法及应用

Kinovea作为一款免费开源的运动分析软件,专为体育领域设计,对运动员的运动过程进行科学分析。本文将该软件应用于道路交通中汽车运动的分析,旨在为道路交通事故的成因分析提供更为精准可靠的依据,并详细介绍了基于Kinovea软件的四种视频车速计算方法,即移动标尺法、固定标尺法、网格法、车载视频分析法。试验结果表明,这四种车速计算方法的精度误差在±2%以内。

As a free and open source physical exercise analysis software,Kinovea is designed specially for the field of sports to scientifically analyze the movements of athletes.This paper applies the software to the analysis of car movement in road traffic,aiming to provide a more accurate and reliable basis for the analysis of the causes of road traffic accidents.Four video speed calculation methods based on Kinovea software are also introduced in detail in the paper,they are the moving ruler method,the fixed ruler method,the grid method and the on-board video analysis method.The test results show that the accuracy error of these four vehicle speed calculation methods are within ±2%.
