摘要利用图像序列对智能交流接触器动态过程进行分析，是智能交流接触器动态过程分析研究中的一项关键技术。在直接线性变换和刚体运动模型的基础上，提出了基于高速摄像机拍摄的智能交流接触器运动部件动态过程的二维序列图像研究三维动态特性的测试方法。从序列图像中获取智能交流接触器运动部件的特征标记点，得到其二维动态特性。根据特征标记点的二维坐标值，以及刚体的运动方程和投影关系的约束方程，联合求解出智能交流接触器的三维空间运动参数。在大量测试的基础上，对智能交流接触器的三维空间动态特性进行综合分析。该测量技术和三维运动参数的算法是智能交流接触器三维动态特性研究的一种有效手段，是智能电器动态特性研究的新方向。

Abstract：The intelligent AC contactor dynamic process is analyzed based on sequence image,which is a key technology for dynamic process analysis of intelligent AC contactor in the study . Based on the direct linear transformation and rigid motion model,3D dynamic testing method of intelligent AC contactor dynamic process is proposed based on 2D sequence image of intelligent AC contactor dynamic process taken by high-speed camera. 2D motion characteristics of intelligent AC contactor are gained by detecting feature points of moving target from image sequence. According to two- dimensional coordinate values of the feature point,as well as combined the rigid motion equation with the constraint equations of projection relation,3D motion parameters of rigid are worked out. In the experimental test data,intelligent AC contactor space dynamic characteristics is comprehensively analyzed. This measurement technology and the algorithm of 3D motion parameters is an effective means for intelligent AC contactor 3D dynamic process research,and it is new research direction in the field of intelligent electrical dynamic research.

Key words： Intelligent AC contactor rigid motion model sequence image 3D dynamic charac- teristics testing
