Definitions
- the establishing a cell adjacency relationship model in the certain time according to the snapshot includes:
- FIG. 4 is a schematic structural diagram of a navigation system route planning apparatus according to an embodiment of the present invention.
- the navigation system divides the actual geospatial space by using the cell of the cellular network as a grid, and establishes a cell adjacency relationship model; here, the so-called cell is a base station antenna overlay. Covered space.
- the historical snapshot can be used together with the current snapshot to construct a directed graph. However, when using this method, the context state of the historical snapshot must be guaranteed. The current state is consistent, so when selecting a historical snapshot, you need to use a recent history snapshot and a historical snapshot that uses index features similar to the current time index feature.
- the optimal path solution from the departure cell to the target cell may be converted to searching for the shortest path on the directed graph.
- a path conversion module 43 is configured to translate the grid level path into an actual route from the departure point to the destination in the actual geographic space.
- a trajectory extraction submodule configured to extract a motion trajectory of the mobile station according to the mobile station cell handover record
- the adjacent value between cells is: a probability of transition between two cells or a length of time required to transfer between two cells.
- a GIS map matching unit configured to convert the grid level path into an actual route from a departure place to a destination in a GIS map
- the computer program instructions can also be stored in a computer readable memory that can direct a computer or other programmable data processing device to operate in a particular manner, such that the instructions stored in the computer readable memory produce an article of manufacture comprising the instruction device.
- the apparatus implements the functions specified in one or more blocks of a flow or a flow and/or block diagram of the flowchart.
- the route planning method, device and computer storage medium of the navigation system provided by the embodiments of the present invention; adopting a two-stage route planning manner, firstly rasterizing the cells of the actual geographical space using the cellular network, and then acquiring from the mobile operator
- the mobile station cell handover record extracts the motion track of the mobile station, so that the motion track information of multiple real mobile stations can be perceived in real time; the path planning is performed in the cell space of the cellular network, and then the route matching is performed based on the GIS map or the satellite map, thereby reducing
- the dependence on the accuracy and timeliness of GIS maps improves the real-time, accuracy and validity of route planning results. Moreover, it can assist in the discovery of GIS map errors, and at the same time give the most fault-tolerant maps. Excellent path. Since the implementation of the embodiment of the present invention is based on a mobile communication network, the deployment cost is low and the scope of application is wide.
