The invention discloses a projection height adjusting method and device, equipment and a medium, and belongs to the technical field of intelligent cabins. The adjusting method comprises the steps that the eye spot position of a driver and the rim position of a steering wheel are obtained; determining a first boundary line on the front windshield according to the eye spot position, wherein the height of each point on the first boundary line is not higher than the height of the eye spot position; a second boundary line on the front windshield glass is determined according to the curved surface passing through the eyespot position and the rim position, and the height of the second boundary line is not lower than the height of an intersection line of the curved surface and the front windshield glass; and adjusting the projection height of the head-up display system to enable the projection to be between the first boundary line and the second boundary line. According to the method, the projection height of the head-up display system can be adjusted more accurately, it is guaranteed that the projection picture is completely displayed in the projection area, a driver can check complete projection information and make an accurate judgment on the driving road condition, and the driving safety is improved.

    本发明公开了一种投影高度的调节方法、装置、设备及介质,属于智能座舱技术领域。该调节方法包括:获取驾驶员的眼点位置和方向盘的轮圈位置;根据所述眼点位置确定前风挡玻璃上的第一边界线,所述第一边界线上各点高度不高于所述眼点位置高度;根据经过所述眼点位置和所述轮圈位置的曲面,确定所述前风挡玻璃上的第二边界线,所述第二边界线的高度不低于所述曲面与所述前风挡玻璃的相交线的高度;调节抬头显示系统的投影高度,以使投影处于所述第一边界线与所述第二边界线之间。该方法可以更加精准的调节抬头显示系统投影的高度,保证投影画面全部显示在投影区域内,使得驾驶员可查看完整的投影信息,对驾驶路况做出准确判断,提高驾驶安全性。
