该SAE标准提供了在典型汽车环境照明条件下确定HUD光学性能的测量方法。它涵盖了室内测量和模拟室外照明，用于HUD虚拟图像的测量。该标准涉及的HUD类型包括w-HUD(挡风玻璃HUD)和c-HUD(组合器HUD)，根据需要参考增强现实(AR)HUD。为汽车合规性设置阈值不在本文档的范围内；但是，给出了一些推荐值以供参考。

This SAE Standard provides measurement methods to determine HUD optical performance in typical automotive ambient lighting conditions. It covers indoor measurements with simulated outdoor lighting for the measurement of HUD virtual images. HUD types addressed by this standard includes w-HUD (windshield HUD) and c-HUD (combiner HUD) with references to Augmented Reality (AR) HUD as needed. It is not the scope of this document to set threshold values for automotive compliance; however, some recommended values are presented for reference.
