A system for calibrating a waveguide-based holographic head-up display that projects an image onto a windshield of a vehicle includes a light diffusion plate located at the center of an eye ellipse to reflect the image projected by the waveguide-based holographic head-up display. An eye movement range projected by the waveguide-based holographic head-up display is located at the center of an eye ellipse, and the eye movement range is divided into a plurality of unit exit pupils. The system also includes a camera positioned to capture an image reflected by the light diffusing plate; and one or more controllers in electrical communication with the waveguide-based holographic head-up display and the camera. The one or more controllers execute instructions to determine a deformation map based on the plurality of corrected individual calibration patterns.

    一种用于校准将图像投影到车辆的挡风玻璃上的基于波导的全息抬头显示器的系统,包括:光漫射板,该光漫射板位于眼椭圆中心,以反射基于波导的全息抬头显示器投影的图像。基于波导的全息抬头显示器投影的眼动范围位于眼椭圆中心,并且眼动范围分为多个单元出射光瞳。系统还包括:摄像头,该摄像头被定位为捕获光漫射板反射的图像;以及一个或多个控制器,与基于波导的全息抬头显示器和摄像头电通信。一个或多个控制器执行指令,以基于多个校正后单独校准图案确定变形映射。
