Description

technical field [0001] The invention relates to the technical field of power line communication, in particular to a method for detecting objects in cable inspection pictures based on a convolutional neural network. Background technique [0002] Cable inspection is generally divided into equipment inspection and channel inspection. Equipment inspection is mainly aimed at the identification of appearance changes and the measurement of electrical parameters for the main cable equipment and auxiliary facilities. Channel inspection is mainly to prevent external force damage to cable equipment caused by construction machinery on the ground above the underground cable channel. In the inspection pictures of the channel, if there are excavator-like mechanical equipment or construction enclosures and other objects, it often indicates that the drilling construction may cause serious damage to the nearby underground cable channel. Therefore, in the daily operation and maintenance of h...
