The Design And Implement Of A Vehicle Driving Simulator Based On OGRE And ODE

The Vehicle Driving Simulator (VDS) has been studied since 30 years ago, to which makes progress when Virtual Reality (VR) is combined. On the basis of virtual environment of vehicle driving, audio works, motive simulation and etc produced by computer in real time, operator could immerse in the virtual driving environment, and conceive driving actions, experience and study how to drive in the real world according to realistic interactive means of real-time senses such as vision, hearing, feeling touch and so on. Obviously, VDS has a lot of advantages as a driving training system. For example, it is low-costs, safety, and effect for time, and used without limits such as climate and field, and it can promote effective and decrease the training period else. Otherwise, as a research tool, VDS can be also used in the study of vehicle's performance, the analysis of driving behavior, driving action and response in danger, reappearance analysis of traffic accident, evaluation of vehicle electric production and evaluation of transport environment. VDS has been used widely as a simulation device for it can supply real driving feelings and operations. So, it is profitable to do some research on it.According to the errand, the writer of this thesis has done a lot of deeply research and application in software design and exploiture of VDS. Recently, the exploiture of most same systems is on the basis of simulation platform that is efficient and accessible, but it is not flexible and very expensive in software purchasing, and it depends on the performances of hardware very much. So, it is not easy to implement widely. If the exploiture is on the basis of SDK of OpenGL and Direct3D, the efficiency is much lower. According to those situations mentioned above, it is possible to keep balance in the cost, running effect and efficiency of the system exploiture. Therefore, utilizing open resource graphics rendering engine (OGRE) and open dynamics engine (ODE) and combining to the theory of VR, the writer designs a serious of software of VDS, which has been tested and used in practice. The mainachievement of this thesis are as follow:Analyzing the main architecture about OGRE and ODE, doing deeply research on the simulation of visualizing dynamics arithmetic, and making a solution about how to use them unitedly.Creating same virtual scenes and vehicle models with modeling software, 3DSMAX, and transform them to the OGRE forms.Realizing a dynamic simulation of traffic signal controlling, and establishing digital scheme on road-net.Realizing the artificial intelligence (AI) vehicles in virtual scense. Enforcing the facticity of driving environment.Realizing 3D audio works and promoting the immersion of the whole system. The results of the system running test show that the operator can precept the realdriving feeling such as vision, audio and touching senses from virtual driving environment, 3D audio works and vehicle dynamic simulation produced by system. Because of the basis of open resources, the software cost of the whole system is cut short, and it can be widely used. Nowadays, the system has been used on VDS for driver training, which is a foundation of the exploiture of VDS for researching. Otherwise, the technique of physics modeling based on OGRE and ODE is not only suit to the exploiture of VDS, but also can be used in fields of military affairs simulation such as robot simulation, virtual battlefield and so on.
