    • Techniques are provided which may be implemented using various methods and/or apparatuses in a mobile device to allow the mobile device to obtain map information associated with at least a portion of an indoor environment comprising a plurality of regions. The mobile device may also obtain additional measurement information associated with at least the portion of the indoor environment, wherein the additional measurement information is based, at least in part, on previously obtained estimated position measurement information associated with a plurality of mobile devices within the indoor environment. The mobile device may determine whether access to at least one of the plurality of regions is either feasible or infeasible to a user associated with the mobile device. The determination may be based, at least in part, on the map information and the additional measurement information.
    • 提供了可以使用移动设备中的各种方法和/或设备来实现的技术,以允许移动设备获得与包括多个区域的室内环境的至少一部分相关联的地图信息。 移动设备还可以获得与室内环境的至少一部分相关联的附加测量信息,其中附加测量信息至少部分地基于与室内多个移动设备相关联的先前获得的估计位置测量信息 环境。 移动设备可以确定对多个区域中的至少一个的访问对于与移动设备相关联的用户是可行的还是不可行的。 该确定可以至少部分地基于地图信息和附加测量信息。

    • The subject matter disclosed herein relates to systems, methods, etc. for creating a routing graph based at least partly on building information, which may include relatively low-detail schematics. For certain example implementations, a method may include obtaining building information descriptive of at least a portion of a building structure and superimposing a grid of points onto the building information. The building information may be analyzed using the superimposed grid of points by projecting multiple rays from multiple points of the superimposed grid of points. At least one routing graph may be created responsive to the analyzing and based at least in part on the superimposed grid of points and the building information. Other example implementations are described herein.
    • 本文公开的主题涉及用于至少部分地基于建筑物信息创建路线图的系统,方法等,其可以包括相对较低细节的原理图。 对于某些示例性实施方式,方法可以包括获取描述建筑物结构的至少一部分的建筑物信息并将点格栅叠加到建筑物信息上。 可以通过从叠加的点网格的多个点投影多条光线来使用叠加的点格网来分析建筑物信息。 可以响应于分析创建至少一个路线图,并且至少部分地基于叠加的点和建筑物信息。 本文描述了其他示例实现。
