The invention discloses an enhanced synthetic vision system suitable for offshore operation. The enhanced synthetic vision system comprises an external flight marine environment visualization module, a sea condition information visualization module, a photoelectric image enhancement module and a laser enhancement display module, the external flight marine environment visualization module reconstructs a virtual flight environment, the sea condition information visualization module digitally displays sea condition information and sea wave information, the photoelectric image enhancement module realizes fusion display of photoelectric image information and three-dimensional geographic information, and the laser enhancement display module performs laser ranging on a target by using a laser range finder and then displays the target in the virtual flight environment. Geographic information of a target is solved in combination with inertial navigation data and photoelectric pose data, a static obstacle database is constructed, and highlight labeling is performed on the target by using OpenGL (Open Graphics Library). Through effective combination with a photoelectric system and advantage complementation, the flight operation capability of the helicopter in the offshore sea area under low-visibility conditions such as night and fog can be remarkably improved.
