Detection method of submarine cable laying surface damage based on computer vision and pixel enhancement

Using ultra-low frequency mixed shock wave breakdown tests, identify the damaged area of the cable, which is susceptible to changes in surface temperature field, resulting in significant deviation between the damage detection position and the actual position. Therefore, it is necessary to design a new method for detecting surface damage in submarine cable laying based on computer vision and pixel enhancement. Using the principle of pixel enhancement to extract and identify damage detection features of submarine cable laying surfaces, thereby completing damage detection of submarine cable laying surfaces. The experimental results show that the damage area and stress amplitude are consistent with the actual height, and have good detection effect, reliability, and certain application value, making a certain contribution to the subsequent maintenance work of submarine cables.
