与编码标签交互以产生取向数据的感测设备
摘要：
提供了一种用于在相对于表面而定位或移动时产生取向数据的感测设备。取向数据指示感测设备相对于该表面的取向，该表面具有设置于其上的编码标签。每个编码标签具有旋转不变结构并且在被该感测设备感测时指示该取向。该感测设备包括：壳体；取向感测装置，配置为使用该编码标签的至少之一来产生该取向数据；以及通信装置，配置为把该取向数据传送给计算机系统以便知道该感测装置相对于该表面的取向。所产生的取向数据表示该壳体相对于该表面的偏转和倾斜中的至少一个，并且该取向感测装置被布置为基于编码标签的该旋转不变结构来感测该编码标签。
摘要（英）：

Provided is a sensing device for generating orientation data when positioned or moved relative to a surface. The orientation data is indicative of an orientation of the sensing device relative to the surface, the surface has a coded label disposed upon it, and the coded label has rotational and invariant structure and is indicative of the orientation when sensed by the sensing device. The sensingdevice includes: a housing; an orientation sensing means configured to generate the orientation data using at least some of the coded label; and a communications means configured to communicate the orientation data to a computer system and to know the orientation of the sensing device relative to the surface. The generated orientation data denotes at least one of the deflection or declination of the housing relative to the surface, and the orientation sensing device is configured to sense the coded label based on the rotational and invariant structure of the encoded label.
