摘　　要：为提升驾驶模拟器后视镜仿真的视野舒适度,提出了一种基于微软基础类库(MFC)的可调节后视镜仿真方法。该方法基于MFC的多线程框架设计后视镜调节模型,通过改变视野范围的方式调节后视镜可视区域,结合Arduino设计后视镜调节按钮,利用串口通信实现MFC程序与Arduino的数据交互,最终采用离屏渲染技术将后视镜显示在虚拟视景中。使用驾驶模拟器对后视镜成像效果进行了验证,结果表明,所提出的可调节后视镜仿真方法满足驾驶员在不同驾驶工况下的后方视野需求,同时保证了后视镜成像的实时性,达到虚拟驾驶仿真的要求。In order to improve the visual field comfort of the driving simulator rearview mirror simulation,an MFCbased adjustable rearview mirror method is proposed.The method is based on MFC’s multi-threaded framework to design the rearview mirror adjustment model.The visual field is adjusted by changing the field of view.The Arduino design rearview mirror adjustment button is used to realize the data interaction between the MFC program and the Arduino.Finally,the off-screen rendering technology is used to display the rearview mirror in the virtual view.Using the driving simulator to verify the rearview mirror imaging effect.The results show that the adjustable rearview mirror designed in this paper meets the driver's rear vision requirements under different driving conditions,while ensuring the real-time performance of the rearview mirror imaging,achieving virtual driving simulation requirements.
