Problems solved by technology

[0002] In the current research on frequent route mining, most of the data sources are GPS (Global Positioning System) data or vehicle-mounted data. This kind of data has dense collection points and short time intervals. Classes, frequent pattern mining and other methods are used to find frequent paths; and base station data are extremely sparsely recorded, so none of the existing frequent path mining methods use base station data

Embodiment 1

[0052]This embodiment provides a method for determining a path. Specifically, the method described in this embodiment is based on extremely sparsely sampled base station data, and digs out the path from one residing point (that is, the departure point) to another with high efficiency. A frequent path of a dwell point (that is, the destination) that is closer to the actual path.

[0053] Here, in practical applications, the base station data has the following two characteristics. The first characteristic is that activities within a certain range will be located at the same location point. The second characteristic is that the time interval for collecting data is long and random. That is to say, for characteristic one, it indicates that there is an offset between the data collected by the base station and the real location, and a sampling point identifies an area, and the size of the area is determined by the coverage of the base station. For feature two, it shows that the data ...

Embodiment 2

[0086] This embodiment provides a path determination device, such as Figure 6 As shown, the device includes:

[0087] A determining unit 61, configured to determine a departure place and a destination from a preset map, and select a first target sampling point in a first direction from the departure place to the destination;

[0088] The obtaining unit 62 is configured to obtain a first group of routes within a first range where the departure point is located; and obtain a second group of routes within a second range where the first target sampling point is located;

[0089] The processing unit 63 is configured to determine whether there is a first path segment satisfying a preset rule in the first group of paths and the second group of paths, and if so, at least use the first path segment to determine the The target route from the origin to the destination.

[0090] In an embodiment, the processing unit 63 is further configured to determine whether the same path exists in ...

Abstract

The embodiment of the present invention discloses a method for determining a route. The method includes: determining a departure place and a destination from a preset map, and selecting a first route in a first direction from the departure place to the destination. A target sampling point; obtaining a first group of routes within a first range where the departure point is located; and obtaining a second group of routes within a second range where the first target sampling point is located; judging the first group of routes and whether there is a first route segment satisfying a preset rule in the second group of routes, and if so, at least using the first route segment to determine a target route from the departure point to the destination. The embodiment of the invention also discloses a path determination device.

Description

technical field [0001] The invention relates to data processing technology, in particular to a path determination method and device thereof. Background technique [0002] In the current research on frequent route mining, most of the data sources are GPS (Global Positioning System) data or vehicle-mounted data. This kind of data has dense collection points and short time intervals. Classes, frequent pattern mining and other methods are used to find frequent paths; and the base station data are extremely sparsely recorded, so the existing frequent path mining methods do not use base station data. Contents of the invention [0003] In order to solve the existing technical problems, an embodiment of the present invention provides a path determination method and device thereof, which can at least solve the above-mentioned problems in the prior art. [0004] The technical scheme of the embodiment of the present invention is realized like this: [0005] The first aspect of the ...
