Three-dimensional vision simulation system for aerial vehicles

Abstract

The invention discloses a three-dimensional vision simulation system for aerial vehicles. The system comprises a human-machine interactive module, a model configuration module, a collision detection module, a vision display module, a communication module, a data storage module and a three-dimensional scene roaming module; simulative operations of a user are processed in parallel; specifically, a human-machine interface is developed via a MFC (Microsoft foundation class) library; pure numbers, numerical curves and three-dimension animations are simulated separately via ProEssential and OpenGL; the communication module uses UDP communication and serial port communication techniques; the collision detection module uses an image-based collision detection optimization algorithm; thus, the whole system meets the basic simulation needs of the user.

Description

technical field [0001] The invention belongs to the technical field of computer three-dimensional simulation, and more specifically relates to a three-dimensional visual simulation system of an aircraft. Background technique [0002] With the rapid development of computer 3D simulation technology and aircraft technology, the study of 3D visual simulation of aircraft plays a pivotal role in the field of aircraft research. Through the 3D simulation system, researchers have fundamentally changed the way they analyze data. They no longer stay in the study of a large number of complex numerical curves, but use 3D animation to reflect the real-time flight status of the aircraft and verify the flight plan design more intuitively and visually. correctness and accuracy. [0003] At present, there have been some research results on the research of aircraft visual simulation system, and there are also some professional visual simulation software on the market, such as FlightGear, Vega...

AI Technical Summary

Problems solved by technology

This method of drawing curves based on controls is more complicated, because there is no numerical curve display control in the MFC class library, and drawing numerical curves through controls needs to call the brush to construct the display environment

[0007] 3. The flight simulation system adopts UDP communication method, which can only receive the data transmission from the host computer on the LAN, but cannot receive the actual flight data of the aircraft.

Can only verify the control algorithm, but not modify the control algorithm

[0008] 4. The simulation system cannot set a specific flight mode, and can only follow the movement of the aircraft from one perspective, without designing a 3D scene roaming function

[0009] 5. The simulation system does not consider the collision detection problem
