Enhanced synthetic vision system suitable for offshore operation

Abstract

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.

Description

technical field [0001] The invention belongs to the field of airborne information processing, airborne photoelectric system technology and comprehensive visual technology, and relates to an enhanced synthetic vision system suitable for offshore operations. Background technique [0002] In recent years, the role of helicopters in offshore surveys and sea rescue has become more and more important. Due to the particularity of the marine environment, the sea surface is often accompanied by harsh sea conditions such as sea fog, sea wind, and waves. The lack of a significant positioning reference object puts the pilot in a state of tension to a certain extent, thus restricting the operational efficiency of the helicopter. Contents of the invention [0003] (1) Purpose of the invention [0004] The purpose of the present invention is to provide an enhanced synthetic vision system suitable for offshore operations, which can provide a clear three-dimensional flight view that is no...
