Embodiment 1

[0024] An embodiment of the present invention provides a method for acquiring static location reference data, such as figure 1 As shown, the method includes:

[0025] 101. Receive point information sent by the floating vehicle, and generate a road route according to the point information.

[0026] Wherein, the floating vehicle may include a vehicle traveling on a road or a vehicle parked on a road, etc., and the embodiments of the present invention are not listed here.

[0027] Wherein, the point information may include, but is not limited to, GPS (Global Position System, Global Positioning System) information of the floating vehicle.

[0028] Wherein, the generating of the road route according to the point information may be implemented in the following ways, specifically including:

[0029] The point information is analyzed to obtain the distribution density of the floating cars; the distribution density is analyzed to generate a road path.

[0030] Wherein, the implement...

Embodiment 2

[0041] An embodiment of the present invention provides a method for acquiring static location reference data, such as figure 2 As shown, the method includes:

[0042] 201. Receive point information sent by the floating vehicle, and generate a road route according to the point information.

[0043] Wherein, the related description of step 201 is the same as the related description of step 101, which will not be repeated in this embodiment of the present invention.

[0044] 202. Query whether there is corresponding static position reference data for the road path, if not, perform step 203; if yes, perform step 207.

[0045] 203. Analyze the point information to obtain the average vehicle speed and road usage rate of the road path.

[0046] 204. Determine whether the average vehicle speed and road usage rate of the road path are within the respective preset threshold ranges, if the average vehicle speed and road usage rate of the road route are within the respective preset thr...

Embodiment 3

[0058] An embodiment of the present invention provides a device for acquiring static location reference data, such as image 3 As shown, the device includes: a first generation unit 31 , a query unit 32 , and a second generation unit 33 .

[0059] The first generating unit 31 is configured to receive point information sent by the floating car, and generate a road route according to the point information.

[0060] The query unit 32 is configured to query whether there is corresponding static position reference data for the road route generated by the first generation unit 31 .

[0061] The second generating unit 33 is configured to generate static position reference data corresponding to the road route according to the point information when the query unit 32 finds that there is no corresponding static position reference data for the road route.

[0062] Further, such as Figure 4 As shown, the first generation unit 31 includes: a first analysis module 311 and a second analys...

Abstract

The invention discloses an obtaining method and a device of static position reference data, which relates to the field of intelligent traffic information service and improves the uptodate state of the obtained static position reference data. The method comprises the steps of receiving point position information sent by floating vehicle, generating a road path according to the point position information, inquiring whether the road path has corresponding static position reference data, and generating static position reference data corresponding to the road path according to the point position information if the road path does not has corresponding static position reference data. The method is mainly applied to the process of obtaining of the static position reference data.

Description

technical field [0001] The invention relates to the field of intelligent traffic information services, in particular to a method and device for acquiring static position reference data. Background technique [0002] Location reference data is one of the basic data for intelligent transportation system applications. Through pre-defined static location reference data, dynamic traffic information can be easily located at specific locations, thereby providing effective dynamic traffic information services. At present, the existing static location reference data acquisition process is to collect map road data, filter locations that need to release dynamic traffic information according to the map road data, and extract these locations to make corresponding static location reference data. [0003] In the process of obtaining the above-mentioned static location reference data, the inventors found that there are at least the following problems in the prior art: when obtaining the sta...
