Method for constructing 3D flying scenario of near space aerostat based on STK

Abstract

The invention discloses a method for constructing a 3D flying scenario of a near space aerostat based on STK. The method includes the following steps: converting the format of a MDL file of the near space aerostat, correcting the color of the MDL file, and increasing movements and defining the movements of the near space aerostat, establishing the flying scenario of the near space aerostat in combination with a synthesized landform map of a flying region, obtaining a 3D flying scenario of the near space aerostat by accessing flight track data and external data drive, and realizing dynamic simulation of the flight process of the near space aerostat by real-time updating the content of the 3D flying scenario. According to the invention, the method can better and dynamically display the flying scenario of the near space aerostat of the air above of a specific area, can switch the center and range of a field of view. The method can produce fine models, has high map resolution, and has expandable data interfaces.

Description

technical field [0001] The invention relates to a technology in the field of computer image processing, in particular to a method for constructing a three-dimensional flight scene of an aerostat in near space based on STK. Background technique [0002] STK (aerospace analysis and visualization software tool) has a good scene demonstration function, and is easy to use and easy to integrate with other software. Based on STK software, adding fine models and high-resolution terrain and landforms, the 3D flight scene can be quickly developed in a short period of time, and the flight data of other computers can be received from the LAN through the reserved interface, and the scene content can be updated in real time. Contents of the invention [0003] Aiming at the shortcomings of the existing technology that cannot be applied to the construction of real-time three-dimensional flight scenes of near-space aerostats and the expansion of data interfaces, the present invention propo...
