The invention discloses an automobile rearview mirror distance identification display method, which comprises the following steps of: acquiring a real-time road condition image at an inclination angle, and acquiring a projection image in a horizontal direction; the height between a lens and the road surface and the vertical distance between the lens and the projection image are pre-measured, and a projection proportionality coefficient is obtained; according to the distance between the road line projection and the lens in the horizontal direction and the projection proportionality coefficient, acquiring actual distance data between the road line and the lens in the horizontal direction; according to the horizontal direction distance between the projection of the moving obstacle and the lens and the projection proportionality coefficient, obtaining the actual distance data of the moving obstacle and the lens in the horizontal direction; the method is very friendly to a driver, and solves the problem that a novice driver hopes to obtain a risk avoidance prompt when the novice driver is in a busy and unknowing way in the driving process.

    本发明公开了一种汽车后视镜距离识别显示方法,倾斜角度采集实时路况图像,并获取水平方向的投影图像;预测量镜头与路面之间的高度、所述镜头与所述投影图像之间的垂直距离,获取投影比例系数;依据所述道路线投影与所述镜头之间的水平方向距离、所述投影比例系数,获取道路线与所述镜头的水平方向实际距离数据;依据所述移动障碍物投影与所述镜头之间的水平方向距离、所述投影比例系数,获得移动障碍物与所述镜头的水平方向实际距离数据;对驾驶人员非常友好,解决了新手司机驾车过程中因手忙脚乱不知所措时希望得到规避风险提示的问题。
