The invention discloses a vehicle speed projection display system based on eyeball tracking and a working method thereof. The vehicle speed projection display system comprises a micro camera, a rotating motor, a placement platform, a micro laser projector and a single-chip microcomputer. The rotating motor is used for driving the placing platform to rotate; the micro laser projector is fixed on the placing platform; the single-chip microcomputer is electrically connected with the micro camera, the rotating motor, the micro laser projector and a center console of the automobile. During work, the single-chip microcomputer calculates the rotating angle of the rotating motor according to a driver face picture shot by the micro camera, then controls the rotating motor to rotate, and controls the micro laser projector to project the automobile speed received from a center console of an automobile to a windshield of the automobile. According to the invention, influence on observation of the driving road condition due to that a driver needs to lower the head to read the vehicle speed on an instrument panel is avoided, and the driving safety and comfort of the driver are improved.

    本发明公开了一种基于眼球追踪的车速投影显示系统及其工作方法,车速投影显示系统包含微型摄像头、旋转电机、放置平台、微型激光投影仪和单片机;旋转电机用于带动放置平台旋转;微型激光投影仪固定在放置平台上;单片机分别和微型摄像头、旋转电机、微型激光投影仪、汽车的中控台电气相连。工作时,单片机根据微型摄像头的拍摄的驾驶员面部图片计算出旋转电机的转动角度后控制旋转电机旋转、并控制微型激光投影仪将从汽车的中控台接收到车速投影至汽车的挡风玻璃上。本发明能够避免驾驶员因为低头读取仪表盘车速而影响对行驶路况的观察,提高驾驶员的行车安全性和舒适性。
