The invention discloses a wide-sea-area long-distance ship height detection method based on holder automatic tracking, and the method comprises the following steps: enabling a holder camera to be in linkage with the fusion data of an AIS system and a radar, and obtaining proper target ship video information in a self-adaptive manner through region division and dynamic planning; obtaining the height of the ship from the captured video data by using an intelligent image recognition technology, and obtaining a measurement height set of the target ship corresponding to different distance areas; and correcting the obtained measured height set of the target ship to obtain the corresponding measured height of the target ship, and storing the data into a database as historical data to carry out historical data auxiliary evidence and provide a basis for next height measurement of the same ship. The method has the advantages that real-time height detection of long-distance small-target ships is achieved based on the ho
