摘要
监测GIS(Gas Insulated Switchgear)组合电器母线舱空间位置状态变化情况是保证GIS组合电器系统安全稳定运行的重要环节。针对户外GIS组合电器母线舱空间位移形变工况监测存在的问题,并基于单目视觉测距方法,提出一种基于嵌入式系统的空间小位移测量方法。设计了两种视觉识别标识,简化了识别过程。通过对摄像头采集的图像进行处理,使用视觉标识获取被测对象的空间小位移,实现对GIS母线舱三维空间位移的非接触式测量。该技术可避免复杂的摄像头系统标定和大量的比对计算,在空间小位移测量应用中有一定的参考价值。
GIS combination of electrical bus cabin spatial position and state monitoring is an important guarantee for GIS combination electrical system safe and stable operation. Aiming at the problems of electrical bus cabin space displacement deformation monitoring in outdoor GIS,the method of spatial small displacement measurement based on embedded system and monocular vision ranging method is proposed. We designed two visual identification marks to simplify the identification process. Non-contact displacement measurement of three-dimensional GIS busbar compartment is realized through the image processing captured by the camera, using spatial visual identity to obtain small displacements measured object. This technique can avoid complex camera system calibration and a large number of comparison calculations,which has some reference value in small space displacement measurement applications.
