    • A method of determining the position of a mobile device using a model. The model comprises a graph comprising a set of vertices and a set of edges between the vertices, and one or more feature functions that take as input one or more vertices of the graph and a set of observations for the device, and return a feature value. The model is constructed by obtaining a map of the geographical area, constructing the graph using the map, wherein the vertices of the graph correspond to areas of the map, and two vertices are joined by an edge when the areas corresponding to the vertices are adjacent and can be travelled between by a device, and building the one or more feature functions using the graph, wherein the feature value of the one or more feature functions indicates the extent to which the observations support the device being positioned in the areas corresponding to the one or more vertices of the graph. The method then comprises the steps of: obtaining a set of observations from the sensors of the device; determining the trajectory for the device that optimises the values given by the feature functions given for the set of observations; and determining the position of the device to be the end point of the trajectory.
    • 使用模型确定移动设备的位置的方法。 该模型包括包括一组顶点和顶点之间的一组边缘的图形,以及一个或多个特征函数,其将图形的一个或多个顶点和装置的一组观察值作为输入,并返回特征值 。 该模型通过获得地理区域的地图,使用地图构建图形来构建,其中图形的顶点对应于地图的区域,并且当与顶点相对应的区域相邻时,两个顶点被边缘连接 并且可以由设备之间移动并且使用该图形来构建一个或多个特征功能,其中所述一个或多个特征功能的特征值指示所述观察支持所述设备位于与所述图像对应的区域中的位置的程度 图形的一个或多个顶点。 该方法包括以下步骤:从设备的传感器获得一组观测值; 确定用于优化由所述观测集合给出的特征函数给出的值的装置的轨迹; 以及确定该装置作为轨迹终点的位置。
