The invention discloses an unmanned ship photoelectric intelligent reconnaissance method based on an intelligent identification technology, and relates to the field of intelligent identification and tracking. The method employs a search radar; and a photoelectric director, a comprehensive control system, a photoelectric display control end, an intelligent identification system and an inertial navigation system. The searching method comprises the steps of target searching, priority ranking, target finger movement, image recognition, target tracking and investigation circulation. The ship-borne radar, the photoelectric tracking system, the ship-borne inertial navigation system and the intelligent recognition system are integrated, and intelligent work of automatic searching, tracking, recognition, investigation evidence obtaining and auxiliary collision avoidance of the unmanned ship can be achieved. During use, after the search radar finds that a target enters a concerned area, the photoelectric tracking system turns to the angle of the target by receiving a target instruction, the automatic identification system identifies the target category, if the target is a suspicious target, automatic tracking reconnaissance evidence obtaining is performed, manual participation is not needed in the whole identification tracking process, and intelligent tracking reconnaissance and navigation collision avoidance are realized.
