Aircraft accident prediction and three-dimensional visualization system

Abstract

The invention discloses an aircraft accident prediction and three-dimensional visualization system and relates to the technical field of aviation accident search. The system plays an important role indetermination of a wrecking search area, planning of a search path and visual expression of wrecking data, and adopts the specific scheme that a visual scene generation and flight wrecking simulationmodule, a teacher station module, a search module and a visualization module are included, and the visual scene generation and flight wrecking simulation module is used for panoramic presentation ofthe environment; the teacher station module is used for providing configuration and preview of flight states and scenes before and after the special situation of the aircraft occurs; the searching module is used for determining a searching area of the aircraft after the special situation occurs; the visualization module is used for generating a simulation model. According to the technical scheme,verisimilitude can be achieved, for a civil aircraft accident search simulation system, verisimilitude is a main index for measuring the system, and modeling and simulation of aircraft accident searchneed a real environment and an aircraft which are high in precision.

Description

technical field [0001] The invention relates to the technical field of aviation accident search, more specifically, it relates to an aircraft accident prediction and three-dimensional visualization system. Background technique [0002] The search for the crashed aircraft is the crucial first step in the search and rescue of civil aircraft. Establishing a reasonable crash search model, quickly determining the crash search area, planning the search path, and visualizing the crash search data are of great significance to civil aircraft search and rescue. [0003] At present, the following problems exist in the determination of the crash search area, the determination of the search path, and the visualization of the crash search data: the determination of the crash search area is based on the continuous space determined on the basis of the analysis of objective conditions such as aircraft status and weather conditions, and the determined The continuous space range is large, whi...

Problems solved by technology

[0003] At present, the following problems exist in the determination of the crash search area, the determination of the search path, and the visualization of the crash search data: the determination of the crash search area is based on the continuous space determined on the basis of the analysis of objective conditions such as aircraft status and weather conditions, and the determined The continuous space range is large, which is not conducive to quickly searching for the crashed aircraft, and the calculated probability distribution of the crashed search area is based on the ordinary normal distribution of points and lines, without considering the influence of the special circumstances of the aircraft crash on the probability distribution; When an aircraft encounters a special situation, the subjective judgment of the pilot will change the flight trajectory and path of the aircraft, making the actual location of the crash uncertain. The existing search path planning considers less influence of pilot human factors, and the search efficiency is low; Most of the existing crash search systems are crash search decision-making systems. There are few studies on the special circumstances of aircraft crashes. The visual expression of the data generated by the crash search is relatively simple, which is not conducive to the understanding and grasp of the crash search data. less positive impact
