The invention relates to an intelligent visual tracking vehicle-mounted display screen device and a control method. The device comprises a display screen, an eyeball tracking module, an illumination sensor, a display screen fixing seat, a controller and a pitching and horizontal direction control motor. The controller tracks the eyeball position of a user through the eyeball tracking module, extracts the distance and angle information of the user relative to the display screen, controls the angle position of the motor in combination with the horizontal and pitching directions, calculates the adjustment angle of the display screen in the horizontal and pitching directions, and automatically adjusts the position of the display screen through the motor to provide the best visual angle for users with different body types; for a bumpy road surface, the controller extracts angular displacement and angular velocity of a fixed position through the gyroscope, calculates motor attitude angle compensation required for balancing jitter, and avoids the influence of vehicle jitter on the attitude of a display screen by compensating a motor control signal in real time; the light sensor can sense the light intensity in the vehicle, the controller automatically adjusts the brightness of the display screen by comparing the light intensity with the standard light intensity, and the best visual effect is presented.

    本发明涉及一种智能视觉跟踪车载显示屏装置及控制方法,装置包括显示屏、眼球追踪模块、光照传感器、显示屏固定座、控制器、俯仰和水平方向控制电机。控制器通过眼球追踪模块追踪用户眼球位置,提取用户相对显示屏的距离和角度信息,结合水平和俯仰方向控制电机角度位置,计算显示屏在水平和俯仰方向上的调整角度,由电机自动调整显示屏位置,为不同体型用户提供最佳视角;对于颠簸路面,控制器通过陀螺仪提取固定位置角位移和角速度,计算平衡抖动所需要的电机姿态角补偿,通过实时补偿电机控制信号,避免车辆抖动对显示屏姿态影响;光线传感器可感知车内光线强度,控制器通过和标准光线强度对比,对显示屏亮度进行自动调节,呈现最佳视觉效果。
