Embodiment 1
[0035] Such as figure 1 As shown, a method for abnormal detection of overhead communication optical cables, the specific steps of the detection method are as follows:
[0036] S1: In the initial stage, when there is no abnormality in the overhead communication optical cable, control the drone equipped with the GPS positioning module and the video capture module to fly directly above the overhead optical cable, adjust the video capture module, and ensure that the communication optical cable is taken from a vertical view; and The GPS location is recorded for each shot; the image taken at that time serves as the reference image.
[0037] S2: When performing anomaly detection, control the UAV equipped with the GPS positioning module and the video capture module to fly directly above the overhead optical cable to take pictures of the communication optical cable, and record the GPS position at the time of shooting; the image taken at this time is used as the image to be detected im...

A method for detecting the abnormality of an overhead communication optical cable includes such steps of shooting an image of the overhead communication optical cable by an unmanned aerial vehicle (UAV) as a reference image when there is no abnormality of overhead communication optical cable; when abnormity is detected, capturing the communication cable by the unmanned aerial vehicle as the imageto be detected; recording the GPS position of the captured image in real time, selecting the reference image whose GPS position is consistent with the image to be detected, converting the reference image and the image to be detected into a gray-scale image, binarizing the gray-scale image, and then filtering to obtain the desired target characteristic image; for the reference image, processing the target feature image of the image to be detected by contour detection, and obtaining and marking the GPS position information of the contour difference. The method of the invention has the characteristics of simple operation, high detection efficiency and high detection accuracy, and is applicable to the field of overhead communication optical cable abnormality detection.
Description
technical field [0001] The invention relates to the field of communication optical cable detection, and more specifically, to a method for abnormal detection of overhead communication optical cables. Background technique [0002] In response to the country's call for "speeding up broadband", the construction of transmission networks, especially communication optical cable lines, has doubled in recent years. Because the communication optical cable line is exposed outdoors for a long time, it is often violated by natural factors such as pollution, lightning storms and bird damage, resulting in various line failures, which pose a serious threat to the safety and stability of the optical cable line communication system. [0003] At present, the existing detection of whether there is any abnormality in the overhead optical cable line mainly depends on the maintenance personnel to patrol along the communication optical cable line. This method has the disadvantage of low efficiency...
