The invention belongs to the field of pipeline detection, particularly relates to a subsea pipeline detection method and system based on an unmanned ship carrying an ROV, and aims to solve the problem of insufficient positioning precision of a pipeline detection robot in the prior art. The method comprises the following steps: generating a navigation route of an unmanned ship based on a route diagram of a target subsea pipeline; the unmanned ship runs according to the sailing route, and the remote control unmanned submersible ROV is released; the unmanned ship scans the target subsea pipeline in real time in a sound wave multi-beam scanning and side scanning mode to obtain reflected sound waves; after scanning of the unmanned ship is completed, remotely controlling the ROV to carry out short-distance scanning on the target subsea pipeline; recording the position of the unmanned ship and the relative position between the ROV and the position of the unmanned ship in real time; and carrying out position matching on the reflected sound wave and the ROV detection data to obtain a combined detection image. According to the invention, automatic external detection of the whole subsea pipeline is realized, and the detected abnormal position is accurately positioned.
