摘　　要：研究海底电缆破损准确监控问题。由于海底与陆地电缆不同,海底电缆往往具备大容量、长距离的特征,一旦发生细微的电缆表皮绝缘裂化,转化的红外表皮扫描报警信号也会较小,在长距离的海水传递中,受到海水阻塞等因素的影响,很容易造成信号衰减。传统的介质损耗因数方法通过检测介质中的红外报警信号进行监控,一旦红外线信号发生衰减,会导致海底电缆破损检测准确率降低。提出了一种配合计算机视觉图像的海底电缆破损智能监控方法。运用像素补偿手段,对细微破损点进行多次迭代补偿增强,克服了传统算法中需要远距离传递信号造成衰减的弊端。实验证明,改进算法能够避免海水深度增加造成的红外线信号衰减的缺陷,提高了海底电缆破损检测的准确率。The submarine cable damage accurate monitoring problem. And the land cable is different, often have the submarine cables capacity, the characteristics of the long distance, once produce subtle cable skin insulation cracking, the transformation of infrared scanning alarm signal will also skin smaller and in the long sea water trans- fer, sea water obstruction by the influence of factors, it is easy to happen signal attenuation. The traditional medium loss factor method through the test of the medium infrared alarm signal monitoring, once the infrared signal producing attenuation, will lead to damage detection accuracy reduce submarine cables. Put forward a kind of computer vision image with the submarine cables damaged intelligent monitoring method. Using the pixel compensation method, in subtle damaged point many times compensation enhanced iteration, overcome traditional algorithm need distance relay signals caused the disadvantages of decay. Experiments show that the algorithm can avoid water depth increases in infrared signal attenuation of the defect, improve the accuracy of the submarine cables damage detection..
