Research and development of 3D driving simulation system

In order to solve the problems of high development cost and few secondary development characteristic in 3D driving simulation system,an implementation method of the 3D driving simulating system is researched and developed by combining 3DMAX modeling software with Newton physics engine and open scene graph engine which two both are open source.The hardware system uses multi-sensor fusion technology to collect drivers’ driving behavior,then the software system control the movement and collision reaction of vehicles,and switch scene perspective based on operation data.The result proves that this method has the advantages of low software development cost,high scene fidelity and excellent dynamic effect.The requirement of record and analysis drivers’ driving behavior is realized.
