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 detects certain combinations of facial expressions and head poses from which errors or problems in operation of the visor system can be inferred. In response to the specified combination of head gestures and facial expressions, the visor system adapts one or more operational or calibration parameters of the visor system to provide a more accurate update of the optical state of the visor.

    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检测面部表情和头部姿态的某些组合,根据这些组合,可以推断出该遮阳板系统的操作的错误或问题。响应于头部姿态和面部表情的这种指定组合,该遮阳板系统适配该遮阳板系统的一个或多个操作或校准参数,以提供对该遮阳板的光学状态的更准确更新。
