The invention discloses an electronic rearview mirror control method and system capable of automatically adjusting the visual field. The method comprises the steps that firstly, the eye point initial position of a driver is obtained; step 2, acquiring an eye point moving distance; 3, calculating the head moving angle of the driver; 4, calculating a view translation angle number; and 5, the image processing unit adjusts the view of the display unit according to the calculated view translation angle. The head movement condition of a driver is acquired through the driver monitoring unit and the driver image acquisition unit, so that the visual field of the electronic rearview mirror is automatically adjusted according to the head movement condition of the driver, and the effect that a traditional rearview mirror obtains an extra visual field through head movement is achieved; besides, a method for calculating the view translation angle of the electronic rearview mirror is adopted, and the angle of head movement is calculated by taking a view image acquisition unit or a display unit of the electronic rearview mirror system as a reference point, so that the head movement of the traditional rearview mirror is simulated to the greatest extent to obtain an additional view effect.

    一种自动调节视野的电子后视镜控制方法及其系统,步骤一:获取驾驶员眼点初始位置;步骤二:获取眼点移动距离;步骤三:计算驾驶员头部移动角度;步骤四:计算视野平移角度数;步骤五:图像处理单元根据所计算的视野平移角度,调节显示单元的视野。本发明通过驾驶员监测单元和驾驶员图像取单元获取驾驶员头部运动情况,从而根据驾驶员头部运动情况自动调节电子后视镜视野,以达到传统后视镜通过头部运动获得的额外视野的效果;另外,采用电子后视镜视野平移角度的计算方法,通过以电子后视镜系统的视野图像获取单元,或显示单元为基准点计算头部运动的角度,以最大限度的模拟传统后视镜头部运动获取额外视野的效果。
