基于视频识别技术的变电站防误操作系统的研究

Research of a substation anti-mal-operation system based on video identification technology

提出了一种对标志牌进行实时视觉识别,进而定位操作人员的变电站防误操作系统。该系统通过便携式视频捕获设备获取当前间隔的标志牌实时视频,并进行识别,结合操作票判断是否走错间隔。给出了整个系统的工作原理和各组成的设计,并详细介绍了采用Hough变换来检测标志牌边框以及采用投影法进行标志牌字符分割的原理和具体实现。最后通过实验室测试和现场试运行的结果验证了本系统的正确性、有效性和工程实用性。

This paper proposes a substation anti-mal-operation system for the operation staff positioning based on the real-time signboard visual identifying technology.In this system,real video of the signboard of current space for identification is captured by a portable video capture device.And then it can distinguish that the operation staffs go into the wrong space whether or not refering to the operation order.This paper gives the operational principles and the design of each component of the whole system.The theories and realization of signboard border detecting method by using Hough transformation and signboard character splitting method by using projection method are also introduced in detail.The correctness,effectiveness and engineering applicability are verified through the results of the lab tests and trial operations at last.
