Problems solved by technology

The 2D plane method is mainly displayed with the help of some third-party controls, such as MFC, DirectUI, BCG, etc. These controls cannot truly simulate the actual state of the scene, and the expressive ability is very limited; the fixed camera method is mainly to install a high-speed camera at a fixed corner of the darkroom for real-time Monitoring, although this method is more realistic, it is expensive, takes up space, and will have an impact on the test environment, and it cannot realize scene zoom-in, zoom-out, and 360-degree rotation functions, nor can it simulate special effects such as antenna signaling

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with specific embodiments.

[0024] A 3D display method of a navigation terminal test scene based on OpenGL, which is applied in the field of navigation terminal test, can truly simulate the test scene, and can perform operations such as zooming in, zooming out, and rotating the scene, so that users can truly experience the test scene. Specifically, the 3D display method of the present invention includes the following steps:

[0025] L1) Mathematical modeling is carried out according to the size and position of the darkroom and each device in the scene.

[0026] The coordinate system used in the mathematical modeling is a Cartesian coordinate system, the origin of the coordinates is the center of the darkroom ground, the east is the x-axis, the south is the z-axis, and the top is the y-axis, the size and position information of the darkroom and each device Obtained from the configuration fil...

Abstract

The invention discloses an OpenGL-based navigation terminal test scene 3D display method comprising the following steps that mathematical modeling is performed according to the dimension position of adarkroom and each set of equipment in the scene; texture modeling is performed according to the external dimension of the darkroom and each set of equipment in the scene; mathematical modeling is performed according to the type and the power of an antenna signal in the scene; mathematical modeling is performed according to the operation trajectories of each set of equipment in the scene; animation buffer calculation is performed according to the data upload rate of each set of equipment in the scene; and an FPS camera model is constructed according to the scene observation mode of the user. The method is applied to the air and static and other test platforms of the field of navigation test so that the actual state of the test scene can be truly simulated and the user can be facilitated.

Description

technical field [0001] The invention relates to the technical field of navigation terminal testing, in particular to a display method for a navigation terminal testing scene. Background technique [0002] With the development and popularization of satellite navigation systems, the micro-navigation industry has become one of the fastest-growing industries. As a basic information system, satellite navigation systems can provide global navigation, positioning and timing services. The satellite navigation system is composed of the space part, the ground control part and the user part. As the user part, the navigation terminal is an important part of the application of the satellite navigation system. The navigation, positioning, timing and other functions of the satellite navigation system are all realized through the navigation terminal. With the deepening of the application of satellite navigation technology in the field of production and life, the scale of use of navigation t...
