Projection system, apparatus and method for projection position adjustment with head position

A projection system, apparatus, and method for adjustment with head position are provided. In an exemplary embodiment, the system may include: a projection device configured to project a graphical image associated with an external target on a transparent body; a head tracking device configured to track and obtain head positions of one or more operators; and one or more processors configured to adjust a projection position of a graphic image on the transparent body based at least in part on a head position of an operator such that the graphic image is conformal with the external target associated therewith, and provide the adjusted image data to the projection device. 提供一种用于利用头部位置进行调整的投影系统、设备和方法。在示例性实施例中，该系统可包括：投影设备，被配置成用于在透明体上投影与外部目标相关联的图形图像；头部跟踪设备，被配置成用于跟踪并获得一个或多个操作员的头部位置；以及一个或多个处理器，被配置成用于至少部分地基于操作员的头部位置来调整图形图像在透明体上的投影位置，使得所述图形图像与其所关联的所述外部目标共形，并将经调整的图像数据提供给所述投影设备。
