A HUD image acquisition and correction apparatus and method for a vehicle includes a HUD patch defined upon a reflective surface of a windshield of the vehicle, a virtual image generator for projecting images within the HUD patch, and a virtual image sensor assembly located within a HUD eyebox region of the vehicle and having a field of view including the HUD patch. A controller is configured to control projection of a predetermined test image within the HUD patch, receive from the virtual image sensor assembly a HUD patch image, determine a compensation function based upon the predetermined test image and the HUD patch image, and provide to the virtual image generator the compensation function for application to raw images prior to projection.

    一种用于车辆的平视显示器图像采集和校正设备和方法,包括限定在车辆挡风玻璃的反射表面上的平视显示器块,用于在平视显示器块内投影图像的虚拟图像生成器,以及位于车辆的平视显示器人眼窗口内并具有包括平视显示器块的视场的虚拟图像传感器组件。控制器被配置为控制预定测试图像在平视显示器块中的投影,从虚拟图像传感器组件接收平视显示器块图像,基于预定测试图像和平视显示器块图像确定补偿函数,并且向虚拟图像生成器提供补偿函数以在投影之前应用于原始图像。
