Provided in the present disclosure are a detection method and system for a base station feeder line, and a related apparatus. The method includes: storing, by an image acquisition terminal, a collected feeder line image of a base station to be detected and an identifier of the corresponding base station to be detected in correspondence; and searching for and acquiring, by an image processing terminal, a target feeder line image according to a detection request, performing image preprocessing on the target feeder line image to convert the target feeder line image into a feature grayscale image, comparing the obtained feature grayscale image with a standard feeder line feature grayscale image, and determining, according to a comparison result, whether a feeder line of a target base station to be detected is correctly installed.
