Abstract: Disclosed are devices, methods and storage media for use in determining position information for imaging devices or mobile devices. In some implementations, a landmark is identified in an image which is obtained from an imaging device which in turn is positioned at a location and in a pose. A virtual two-dimensional image that would be visible from the landmark is determined based, at least in part, on the pose. The location or position information is based, at least in part, on the virtual two-dimensional image.

Abstract: A method for template matching is described. In one implementation, an image including a target object is captured by a camera. A pose of the camera is estimated based, at least in part, on peripheral information from the image. Pre-selecting is performed on a set of pose templates by matching the pose of the camera to poses associated with pose templates to identify a set of matching pose templates. The template matching for the target object is then performed using the set of matching pose templates.
Abstract translation: 描述了模板匹配的方法。 在一个实现中，包括目标对象的图像由相机捕获。 至少部分地基于来自图像的外围信息估计照相机的姿势。 通过将摄像机的姿态与姿势模板相关联的姿势匹配以识别一组匹配的姿势模板，对一组姿势模板进行预选择。 然后使用一组匹配的姿势模板来执行目标对象的模板匹配。

Abstract: A digital map having a routing path is created. Points in at least a majority of a linear length of the path may be constrained so that they are disposed substantially equidistant between structural features that are bounding navigable spaces in a structure. The creating of the path may include selecting a connected component corresponding to some or all of the navigable spaces. A morphological process may be performed on the connected component to create the path.

Abstract: Systems, apparatus and methods for merging maps used by a positioning server are presented. Original maps are overlaid, concatenated or inset to create a more detailed map. The original maps are from different sources and/or in different formats. By merging or fusing maps together, a positioning server may create a better structural map, which is in turn used to create improved positioning assistance data.
