摘要
由于开关电弧的发光特性和电器触头系统及灭弧室的反光特性,使从高速图像采集系统拍摄到的图像中很难观察到电器触头。应用直方图及局部直方图的图像增强算法对电弧图像增强处理,以期在观察到电弧图像的同时也观察到触头和燃弧过程中灭弧室中的细节情况。仿真结果表明,该方法能清楚地观察到触头和电弧的相对位置。
It's difficult to find contact from the image photographed by high-speed image sampling system because of the light reflection characteristics of switching arc, contact and interrupter. It do enhancement process to arc image by image enhancement algorithm of histogram and local histogram. In order to find the arc image and on the same time can find contact and the interrupupter's detail in the arcing process. The simulation result shows that the contact and arc's relative position can be observed clearly by this method.
