The invention relates to the technical field of HUD brightness adjustment, and relates to an AR-HUD display brightness adjustment method, system and device. According to the scheme, the scene image on the windshield in the view field of a driver is collected, the scene image comprises the shadow of the object projected on the windshield, then the environment brightness of the display area in the scene image on the windshield is detected, and the target display brightness is displayed according to the environment brightness of the display area and the corresponding relation between the preset environment brightness and the target display brightness. And then the light transmittance of the sub-light-transmitting area corresponding to the display area is adjusted according to the target display brightness, so that the brightness of an image projected to the display area of the windshield after a light beam corresponding to the AR-HUD display image penetrates through the light-transmitting area of the brightness adjusting device is the corresponding target display brightness. According to the scheme, the projection of the external object on the windshield is fully considered, the brightness is adjusted on the light emitting side of the AR-HUD display, the independence of the AR-HUD system is ensured, and the AR-HUD system is more flexible to use.

    本申请涉及HUD亮度调节技术领域,涉及一种AR‑HUD显示亮度的调节方法、调节系统及调节装置。本申请的方案通过采集驾驶员视野内挡风玻璃上的场景图像,包括物体投射在挡风玻璃上的阴影,然后,检测挡风玻璃上的场景图像中显示区的环境亮度,并根据显示区的环境亮度、以及预设的环境亮度与目标显示亮度之间的对应关系,得到显示区的目标显示亮度,然后再根据目标显示亮度调节显示区对应的子透光区域的透光率,使AR‑HUD显示图像对应的光束透过亮度调节装置的透光区域后投射至挡风玻璃的显示区的图像亮度为对应的目标显示亮度。本申请的方案充分考虑到了外界物体在挡风玻璃上的投影,并在AR‑HUD显示器的出光侧对亮度进行调节,保证了AR‑HUD系统的独立性,使用更加灵活。
