真车信号采集的虚拟驾驶交互控制研究

利用真车为控制对象,借助DSP处理器TMS320F2812实时地采集驾驶者驾驶汽车而产生的方向、速度、刹车等运动参数,使用串口将采集到的信息传输到计算机中构建的虚拟环境中,实时地完成与虚拟环境的智能交互控制。利用TMS320F2812的模数转换模块和通用I/O模块完成信号的采集和处理,同时为了提高汽车虚拟驾驶的真实感,使用Unre-al引擎渲染虚拟场景,开发了高度真实感的虚拟驾驶场景,使驾驶者在由计算机构造的虚拟场景中获得如同在真实环境中训练的效果。系统已经应用于虚拟校园漫游当中,具有较好的实时性,应用前景广阔。

Research on interactive control of virtual driving of real car signal acquisition

The real car is used as the control object,and the parameters such as direction,speed and breaking are gottn in real time.By using dsp TMS320F2812,the information is transferred to computers by serial communication to interact with its virtual environments to realize the realtime intelligent interactive control.The analog-digital conversion module and the general I/O module of TMS320F2812 is used to achieve the signs’ acquisition and processing.In order to improve the immersion feeling when driving,a game engine-unreal is introduced to create a large-scale and complex virtual environment,so drivers could get the same training effect in our virtual driving system as in real training.The research result is used in the virtual campus system and the good results is obtained.
