    Abstract: A vehicle windshield display system (12) for detecting obstruction of a vehicle (10) operator (16)'s field of view (14) by a windshield display (18). The system (12) provides closed-loop feedback to perform a visual check of what is actually being displayed on a windshield display (18) in order to avoid obstructing an operator (16)'s field of view (14). The system (12) includes a windshield display (18) configured to be installed into a vehicle (10) and configured to display a graphic (20) in a field of view (14) of an operator (16) of the vehicle (10), a camera (22) configured to determine an image of the graphic (20) displayed by the windshield display (18), and a controller (28) configured to determine if the image indicates that field of view (14) is obstructed. The camera (22) is used to monitor the windshield display (18) and provide feedback to the controller (28) so that appropriate adjustments to the graphic (20) being displayed can be made.

    Abstract translation: 一种车辆挡风玻璃显示系统（12），用于通过挡风玻璃显示器（18）检测车辆（10）操作员（16）的视野（14）的阻塞。 系统（12）提供闭环反馈以执行对在挡风玻璃显示器（18）上实际显示的内容的视觉检查，以避免妨碍操作员（16）的视野（14）。 所述系统（12）包括挡风玻璃显示器（18），所述挡风玻璃显示器（18）被配置为安装到车辆（10）中并且被配置为在车辆（10）的操作员（16）的视野（14） ），被配置为确定由挡风玻璃显示器（18）显示的图形（20）的图像的相机（22），以及被配置为确定图像是否指示视场（14）被阻挡的控制器（28）。 照相机（22）用于监视挡风玻璃显示器（18）并向控制器（28）提供反馈，从而可以对显示的图形（20）进行适当的调整。

    Abstract: A windshield display system (10) and method (400) of operating the same configured to detect an obstruction of light projected by the system (10). A light source (22) emits a light beam (24) that reflects off a scanning mirror (26) to direct the light beam (24) to a desired on a windshield (12). The system (10) includes a light detector (32) configured to detect emitted light (34) generated in response to the light beam (24) illuminating the desired location (28). The system (10) is arranged so the light beam (24) and the emitted light (34) that is detected travel essentially the same light path (30) between the scanning mirror (26) and the windshield (12). As such, an obstruction of the light path (30) is readily detected based only on the intensity of the emitted light (34) detected by the light detector (32).
