A virtual visor system is disclosed that includes a visor having a plurality of independently operable pixels that are selectively operated with a variable opacity. A camera captures an image of the driver or other passenger's face, and based on the captured image, a controller operates the visor to automatically and selectively darken a limited portion thereof to block the sun or other illumination source from illuminating the driver's eyes while making the remainder of the visor transparent. The visor system advantageously predicts a future position of the driver's head or eyes when the driver's head is in motion. Based on the prediction, the optical state of the visor is actively updated to anticipate future movement of the driver's head. In this manner, some negative effects of measurement and processing latency are mitigated when responding to fast head motion.
公开了一种虚拟遮阳板系统,其包括具有多个可独立操作的像素的遮阳板,这些像素利用可变的不透明度被选择性地操作。相机捕获驾驶员或其他乘客的面部的图像,并且基于所捕获的图像,控制器操作该遮阳板以自动地且选择性地使其有限部分变暗,以阻挡太阳或其他照明源照射驾驶员的眼睛,同时使该遮阳板的其余部分是透明的。该遮阳板系统有利地当驾驶员的头部处于运动中时预测驾驶员的头部或眼睛的未来位置。基于该预测,有前瞻性地更新该遮阳板的光学状态以预期驾驶员的头部的未来移动。以这种方式,当对快速头部运动做出响应时,减轻了测量和处理时延的一些负面影响。
