摘要
针对电力电缆埋于地下不利于故障定位的问题,文中利用增强现实技术将电力电缆的现实影像转换到虚拟屏幕中,使得电力电缆故障定位更加方便、快捷。该故障定位策略通过将电缆当前所处环境的图像编码数据与位姿数据投射到增强现实显示设备中,同时能够将获取的图像与典型模型库进行对比和匹配。用此步骤生成的图像源数据触发三维定位注册,实现故障电缆的快速定位,并将故障电缆的虚拟影像显示到增强现实显示设备中。文中所述的电力电缆故障定位策略,能够实现在不开挖电缆、不现场勘探的情况下,快速、准确地定位故障电缆。通过将电缆状态真实地显示在增强现实显示设备上,方便检修人员快速找到故障。该电力电缆故障定位方法不受电磁波的影响,在非故障线路段检测时也无需停电,显著减少了检修难度与停电时间。
Aiming at the problem that buried power cable in the ground is not conducive to fault location,the latest augmented reality technology is used to convert the real image of power cable to the virtual screen,making the fault location of power cable more convenient and fast in this paped.By projecting the image coding data and the current pose data of the cable's current environment into the augmented reality display device,and comparing and matching the acquired image with the typical model database,the image source data generated in this step triggers the 3D location registration,so as to realize the fast location of the fault cable and display the virtual impact of the fault cable to an augmented reality display device.The fault location strategy of power cable described in this paper can locate the fault cable quickly and accurately without excavating the cable and field survey.It is convenient for the maintenance personnel to find the fault quickly by displaying the status of the cable in the augmented reality display equipment.The fault location method of power cable in this paper is not affected by electromagnetic wave,and there is no need to cut off the power supply when detecting the non fault line section,which greatly reduces the difficulty of maintenance and cut off time.
