    • A method and apparatus is provided for identifying information to facilitate adjusting a projector's position to achieve a specified projected image on a projection surface. In an embodiment, a computing device comprising one or more sensors, which have a known spatial relationship with a projector, includes a position adjustment service configured to identify, based at least in part on the known spatial relationship between the one or more sensors and the projector, a current position of the projector relative to positions of a plurality of reference points that define a projection surface. The position adjustment service is further configured to determine a target position for the projector, determine differences between the current position of the projector and the target position for the projector, and perform one or more actions based upon the determined differences between the current position of the projector and the target position for the projector.
    • 提供了一种用于识别信息以便于调整投影仪的位置以在投影表面上实现指定的投影图像的方法和装置。 在一个实施例中,包括与投影仪具有已知空间关系的一个或多个传感器的计算设备包括位置调整服务,其被配置为至少部分地基于一个或多个传感器与所述传感器之间的已知空间关系来识别 投影仪,投影仪相对于限定投影表面的多个参考点的位置的当前位置。 位置调整服务还被配置为确定投影仪的目标位置,确定投影仪的当前位置与投影仪的目标位置之间的差异,并且基于确定的投影机的当前位置之间的确定的差异执行一个或多个动作 投影机和投影机的目标位置。
