摘　　要：针对风洞试验中轨迹测量问题,设计了由3个一维线阵CCD成像单元组成的实时空间位移测量系统。提出了一种基于特征边缘提取的组合特征定位WBT算法,可以有效提高系统精确度和抗振动干扰能力。应用该系统在风洞中测量了覆冰导线的舞动轨迹,完成了导线舞动规律研究。The real-time spatial displacement measuring system consisting of three one- dimensional linear CCD imaging units is designed to deal with the problem of locus measurement in the wind tunnel test. It puts forward WBT algorithm with the combination of characteristics positioning based on charaeteristic edge extraction for the purpose of improving the accuracy of the system and the ability of anti-vibration interference. As a result of the application of this sys- tem, the iced conductor galloping locus is measured in the wind tunnel and the research of the conductor galloping locus is done as well.
