Abstract

The invention discloses a construction method for a 3D dynamic visual simulation platform for multimode navigation. The method comprises the following specific steps: a human-computer interaction platform is constructed on the basis of MFC (Microsoft foundation classes) in VC++ and OSG 3D rendering engine environment, a 3D digital earth scene and natural environment are rendered with an OSGEarth terrain rendering toolkit, and a 3D model of an airplane and a virtual simulation scene model of an airport are established with 3D modeling software and loaded to the 3D digital earth scene. Key point data of a flight line is acquired, and interpolation way point data is obtained through processing and used for driving flight of the airplane. During flight of the airplane, a rover is used for tracking and observing the airplane, flight data of the airplane is updated by an event processor, and the flight data is displayed in real time. The construction method has the advantages of easiness in secondary development, real timeliness and high efficiency, and increases the real-time efficiency of data display.

Description

technical field [0001] The invention belongs to the technical field of communication, and further relates to a construction method of a multi-mode navigation three-dimensional dynamic visualization simulation platform in the technical field of computer simulation. The invention can provide a dynamic simulation platform with three-dimensional visualization effect for the multi-mode navigation system, and the platform can be used to provide dynamic flight-related data for the test of the hardware equipment of the multi-mode navigation system. Background technique [0002] The aircraft navigation system is a complete set of equipment that can determine the position of the aircraft and guide the aircraft to fly according to the predetermined route. Early aircraft mainly relied on visual navigation, and then gradually appeared the Instrument Landing System (ILS), Volt Navigation System (VOR) and Microwave Landing System (MLS), focusing on ensuring the flight safety of civil aviat...
