摘　　要：在汽车碰撞试验中,高速影像系统广泛应用于测试对象的运动分析。但实践中,我们注意到几类常见因素经常影响测量导致数据误差。因此,纠正数据误差是应用高速影像系统时需要面对的问题。本文在结合实践经验的基础上重点探讨这些因素对运动分析的精度影响,通过理论分析、试验验证和软件计算相结合的方法提出相应的解决方案,减少数据误差和提升试验质量。In the automobile collision test,the high-speed image system is widely used in the motion analysis of test objects.However,in practice,we noticed that several common factors often affect the measurement and cause data errors.Therefore,correcting data errors is a problem that needs to be faced when applying high-speed image system.This article focuses on exploring the impact of these factors on the accuracy of motion analysis based on practical experience.By combining theoretical analysis,experimental verification and software calculation,it proposes corresponding solutions to reduce data errors and improve test quality.
