secondly, direct theoretical calculation based on the classical equations of heat transfer;
and thirdly, a simplified theoretical calculation method called semi- experience,
semi-theoretical method. From the view of real-time visual simulation, the simulation
means to display the effect of variety of materials. The analysis of each graphic ele-
ments created in scene (terrain, buildings, vegetation and artificial entities, etc.), ac-
cording to their characteristics in the infrared image conditions. When modeling in
MultiGen Creator, one needs to appropriately set the IR imaging attribute ( this is a
gray- chromatography 4096 ); when OpenGVS imported the model, the infrared
properties of the model needs to be opened, one needs to set the infrared attribute on,
then can get the thermal imaging results. In the process of this, a lot of modeling
techniques are involved under non- real-time status, not tired given the space. For
analog active infrared observation device, one can add the green pixel point light source
to simulate infrared searchlight illuminated .

5 Conclusion

The results of the night driving training simulation shown in this research paper have
been applied in a variety of driver training simulators, and received very good training
effect. The results can also be applied to other training systems (e.g. fire training si-
mulators) night vision visual simulation.
