The present invention discloses a vessel navigation aiding facility data automatic extraction method based on an S-57 sea chart. The method comprises the following steps of: Step 1: inputting vessel navigation aiding facility data in an interactive channel input manner; Step 2: inputting a target with a special shape in a manual input manner; and step 3: automatically extracting point data of a buoy, a beacon and a lighthouse. The vessel navigation aiding facility data automatic extraction method based on the S-57 sea chart, disclosed by the present invention, solves the problem of difficulty in extracting vessel navigation aiding facility data of a vessel traffic management system (VTS). According to the vessel navigation aiding facility data automatic extraction method, based on the vessel navigation aiding facility data such as a channel, anchorage ground, the buoy and the like contained in the S-57 sea chart, in combination with specific requirements of the VTS on the vessel navigation aiding facility data, the vessel navigation aiding facility data are automatically extracted, so that the acquisition, loading and management efficiency of vessel navigation environment data are improved, and the vessel navigation environmental data consistency in two-dimensional and three-dimensional display is guaranteed.
