摘　　要：相比传统的按键控制,通过手势控制汽车电动天窗、电动遮阳帘开闭,可以增强汽车驾驶的交互性能,提高汽车行驶安全性。因此,文章提出了采用反射型红外光耦感知,微型控制器进行信号识别的方案,设计并制作了相应的电动天窗和遮阳帘手势识别模块,该模块利用BF7112A微型控制器,实时采集四路光电二极管的通断信号,根据这些信号的变化过程,识别手势的动作方向,从而控制天窗和遮阳帘相应动作。通过实验显示,该模块对手势动作的单次识别准确度达到90%以上,达到了实际应用要求。Compared with the traditional button control,controlling the opening and closing of the electric sunroof and electric sunshade through gestures can enhance the interactive performance of car driving and improve the safety of car driving.Therefore,the scheme of using reflective infrared optical coupling sensing and microcontroller is proposed,design and make the corresponding electric skylight and shade gesture recognition module.The module using BF7112A microcontroller,and real-time collect four photodiode signal,according to the change of the signal process,identify the direction of gestures,so as to control the skylight and shade corresponding action.According to the experiment,the accuracy of single recognition of gesture is more than 90%,which meets the requirements of practical application.
