Embodiment Construction

[0019] Specific implementation plan

[0020] The following results take a detailed description of the three-dimensional visualization software provided by the self-guarantee technology provided by the present invention:

[0021] 1. Three-dimensional scenario exhibition based on B / S architecture

[0022] The three-dimensional visualization software of the independent security system is developed by Django framework. Django is based on the open source web framework of the Python language, which features a model (Model), view, and controller's MVC design mode, which specific responsibilities such as figure 2 Indicated. The key advantage of this design pattern is that all components of the system are loosely, each with a clear purpose of the Django-driven web application, can be independently changed without affecting other parts. Also because Django is developed based on open source Python language, the server rear end can use Python-based script and algorithm, greatly simplify the...

Abstract

The invention discloses a three-dimensional model hierarchical fault display of an aerospace vehicle, and a method for realizing three-dimensional model information extraction and animation interaction. The three-dimensional visualization software of the autonomous support system of the aircraft mainly includes the construction of a software B / S framework and the extraction of three-dimensional solid model information. And format conversion, 3D model display and the addition of animation interactive operation, faulty product display and perspective component operation. The construction of the software B / S framework is mainly responsible for the display function of the 3D scene; the information extraction and format conversion of the 3D solid model are mainly responsible for the extraction of the key information of the model, so as to achieve the purpose of lightweight model; the display of the 3D model and the addition of animation interactive operation The module is mainly responsible for adding models, cameras, light sources, and renderers to realize model rollover, panning, and zooming; the faulty product display and perspective component module is mainly responsible for the positioning of faulty modules so as to highlight the location of the faulty system and help users visualize interference components. The invention can realize hierarchical display of three-dimensional models, three-dimensional animation interaction, fault location and highlight display, and has extremely high real-time performance and stability.

Description

Technical field [0001] The present invention relates to aircraft health management three-dimensional modeling techniques, mainly related to the three-dimensional model hierarchical fault diagnosis of space aircraft, and three-dimensional model information extraction and animation interaction. Background technique [0002] During the flight of astronauts, sensor data is required to determine the attitude, motion, and health status of important components. The current 2D display diagnostic software has a good role in assistance command, rapid analysis, judgment, and decision-making, but three-dimensional visualization software simulation has a great advantage in displaying effects and development space than two-dimensional display software. The three-dimensional visualization technology is the advanced frontier technology of the program data analysis and image recognition technology in 1980. It has the advantage of reproducing objects in the three-dimensional view, truly reflecting...
