The invention discloses a steel pipe pile axis perpendicularity monitoring system based on laser scanning, and the system comprises two laser scanners which are installed on a ship body and are used for obtaining the three-dimensional coordinates of a plurality of measuring point positions of two horizontal plane single pipe pile outlines under a ship body coordinate system; the two double-shaft inclinometers are mounted on the ship body and used for measuring the inclination angles of the upper layer and the lower layer of the ship body; the GPS moving stations are installed on decks on the two sides of the ship and used for measuring local engineering coordinate values according to the established ship body coordinate system and the ship body inclination angle; and the monitoring module is used for calculating local engineering coordinates according to the three-dimensional coordinates of the single pipe piles on the two horizontal planes under the ship body coordinate system through a coordinate conversion
