Shi-tomasi角点检测算法在高压断路器机械特性测试中的应用

Gaoya dianqi
操作机构的机械特性测试可以有效诊断高压断路器的机械故障，常用的机械特性测试方法有安装直线位移传感器和角度传感器两种。这两种传感器都需要固定安装在操作机构上，不同断路器可能需要不同的工装和传感器，通用性差，并且固定安装可能会增加机械故障发生的概率。目前，利用非接触式的图像识别方法，测试高压断路器的机械行程受到研究人员的广泛关注。文中介绍了一种非接触式测量方法，在高压断路器操作机构活动拉杆位置贴具有反光功能的对角扇形标识物，利用高速相机拍摄高压断路器动作过程中标识物，采用Shi-tomasi角点检测方法 ...

基于融合分割与形态特征分析的绝缘子自爆识别

Dianci bileiqi
针对传统方法绝缘子自爆缺陷识别率低，存在对双串绝缘子目标分割困难的问题，本研究提出一种基于融合分割与连通域形态特征分析的绝缘子自爆识别方法。该方法首先对绝缘子红外图像进行双阈值分割，对可视光图像进行HSI颜色特征分割，采用逻辑运算实现融合分割出目标区域；然后对绝缘子目标区域进行形态学滤波和粘连连通域分离处理；接着对绝缘子连通域进行最小外接矩形定位，并构建外接矩形中点位置模型，采用最小二乘法寻找最优分离直线实现双串绝缘子分离，最后对相邻绝缘子间距的大小设立阈值实现自爆缺陷识别。试验结果表明 ...
