Research On UAV Scene Simulation Based On MAK

In view of UAV’s promising characteristic, it plays a more important role and has drawn moreconsiderable attention in many fields such as military and civil. In recent years, as the virtual realitytechnology has been widely applied in system simulation, the scene simulation technology of thevirtual reality has been applied in UAV flight simulation.This paper mainly introduces how to build the UAV flight simulation system base on MAKsimulation platform, and analyses detailedly design requirements of real-time science simulationsystem, medeling methods of the UAV and three-dimensional terrain and the implementation methodof system simulation.According to the UAV scene simulation system and comparing of several visual simulationsoftware,this paper chooses the MAK simulation platform and makes the overall design of the scenesimulation based on MAK.The article creates the UAV three-dimensional models through the Creatorsoftware, sets parameters for the UAV, and generates the UAV models for MAK scene simulationplatform.The paper uses the new medeling method of generating three-dimensional terrain from atwo-dimensional data matrix.Namely, the paper creators firstly two-dimensional data matrix by whichthe grayscale image is generated in Matlab, then convertes to the terrain data file of DED format bymeans of the image, finally generates the three-dimensional terrain model based on the terrain datafile by the use of a number of Creator technologies. This paper realizes that the createdthree-dimensional terrain model is loaded into MAK simulation platform.The UAV scene simulation program is compiled by the use of the development kits in MAK inthe VC++6.0compiler environment.The simulation results show that the UAV in the systemsimulation has a fluent data communication with the outside, and completes fights simulation taskssuccessfully.The whole simulation system has human-computer interaction and high realistic scene,and achieves a good visual effect.
