摘要:
随着视频监控技术成为变电站自动化及电网自动化的一个重要手段,对隔离开关的视频监控图像处理算法的研究也提上了一个更高的层次。在分析经典边缘检测算子的基础上,针对输电线高压隔离开关的具体图像特征,提出了一种适合其自身特征的边缘检测算法,该算法从主动识别方面考虑,只处理局域图像,大大减少了处理量,提高了处理速度。最后,对GW17-550D型高压隔离开关的合状态和GW22-12型隔离开关的开状态分别采用经典算法和该文的算法进行了仿真,结果表明本文的方法更满足实际要求。

Abstract:
The television monitoring technology becomes an important method in the automation of the substation and electrical network, which raises a higher level to the switch frequency monitoring picture processing algorithm research. Based on the analysis of the classical edge detectable operator, and in view of the high voltage switch characteristic which is in the transmission line, one edge detectable algorithm is proposed.This algorithm considers initiatue recognition, and just paritialy process the images, this paper which reduces a huge processing, and raises processing speed. The GW17-550D type high voltage switch of close situation and GW22-12 of open situation are adopted classic edge detectable operator and the proposed detectable algorithm respectively to simulate.The simulation results show that the new algorithm is more satisfied.
