超大规模视景系统中的建模与纹理技术研究   总被引:5,自引:0,他引:5  
三维场景的建模和纹理映射是汽车驾驶模拟器系统开发中的关键技术。论文对基于NURBS曲面法线的路面纹理(含路标线等)自动校准和生成技术、基于高程的的多重纹理映射生成技术及模型和纹理的无缝切片等技术进行了系统的研究,并给出了示例。  相似文献

As hybrid vehicles introduced the motor, the vehicle structure has a significant change in the power matching. Adriver-vehicle-road closed-loop semi-physical simulation system, which makes real driving parts together with the simulation car,will bring convenience to the new car design. We used the computer software to simulate the road with a slope, curve and someother features based on the actual road condition, and analyzed the whole road scene in addition to geometry and physicalcharacteristics. Analyzing and constructing the vehicle dynamics basic template, appropriate changes to the template can obtainthe desired vehicle dynamics model with an external device to control the model vehicle. It combined the physical operation system with visual display, which gave us real driving feelings and increased the vehicle design predictive accuracy.  相似文献
