State 1 primary election gas station POI points to be matched, and according to matching result, determine adding for the stop Point matching to be detected
Petrol station POI point, also includes：
If the anchor point to be detected is equal to or more than the described 4th apart from threshold with the distance of arbitrary primary election gas station POI points
Value, then filter primary election gas station POI points.
When detection anchor point is equal to or more than the 4th distance threshold with the distance of arbitrary primary election gas station POI points, then
Filter primary election gas station POI points, it is ensured that be filtered out than larger primary election gas station POI points with anchor point distance to be detected,
Data capacity has been simplified, matching precision has been improve.Preferably, the 4th distance threshold is 70m.
When vehicle is parked near gas station POI points, Some vehicles can produce serious drift, cause anchor point to be detected
There are a large amount of duplicate data with the matching of gas station POI points.Thus, the result data after the matching filtration of same vehicle is needed
Carry out data merging, will same vehicle merge into a data in the data of same gas station POI points.A large amount of duplicate data
Can be judged according to the stop number of times of vehicle and berthing time.For example, vehicle stops number of times in the odd-numbered day of a certain gas station POI points
More than 100 times, or vehicle is less than given threshold at the interval of any berthing time twice of a certain gas station POI points, then will
Data are merged.Realize being processed with the redundancy of the data of the gas station POI points of stop Point matching to be detected with this, improve data
Value.
Example IV
Fig. 4 is a kind of flow chart of the recognition methodss of gas station's anchor point that the embodiment of the present invention four is provided.It is of the invention real
Example is applied on the basis of above-described embodiment, the position according to the anchor point to be detected is further optimized, described at least one
The position of primary election gas station POI points and the road net data in the region to be detected, by the anchor point to be detected with it is described extremely

The operation of POI points.
Correspondingly, the method for the present embodiment includes：
S410, the gas station POI that will be included in region to be detected that anchor point to be detected and the anchor point to be detected are located
Point is matched, and determines 1 primary election gas station POI points of the anchor point to be detected.
S420, for each primary election gas station POI points, if between anchor point to be detected and primary election gas station POI points
Distance is equal to or more than first distance threshold and less than the 4th distance threshold, and the anchor point to be detected and anchor point
More than the width of the anchor point arest neighbors road, the anchor point to be detected adds the distance between arest neighbors road with the primary election
Petrol station POI point is located at the homonymy of corresponding primary election gas station road, and the anchor point to be detected exists with primary election gas station POI points
Projection on corresponding primary election gas station road is located at the homonymy of the anchor point arest neighbors road, then by the primary election gas station
POI is defined as the gas station POI points of stop Point matching to be detected, wherein the 4th distance threshold is more than described first apart from threshold
Value.
Wherein, the distance between anchor point to be detected and anchor point arest neighbors road are more than the anchor point arest neighbors road
Width.Preferably, the distance between anchor point to be detected and anchor point arest neighbors road are more than the nearest neighboring trace of the anchor point
The width on road and 1m sums.It is highly preferred that the distance between anchor point to be detected and anchor point arest neighbors road are more than 5m.It is to be checked
Survey whether anchor point is located at the homonymy of corresponding primary election gas station road with primary election gas station POI points, can be stopped according to be detected
By point and the projection join line of corresponding primary election gas station road and the positive north of 2 points of the line in front and back of primary election gas station road
To the relation at angle, and the projection join line and primary election gas station road of primary election gas station POI points and corresponding primary election gas station road
The relation at the direct north angle of 2 points of line determines before and after road.
The present embodiment passes through to determine primary election gas station POI points, when between anchor point to be detected and primary election gas station POI points
Distance is equal to or more than the first distance threshold and during less than four distance thresholds, and anchor point to be detected and the nearest neighboring trace of anchor point
The distance between road, the position relationship of anchor point to be detected primary election gas station road corresponding with primary election gas station POI points, and treat
The position of the corresponding anchor point arest neighbors road of detection projection of the anchor point with primary election gas station POI points on primary election gas station road
Relation, when three's satisfaction imposes a condition, it is determined that the gas station POI points of stop Point matching to be detected, improves and stops with to be detected
By the accuracy of the gas station POI points of Point matching.
In another preferred implementation of the present embodiment, by anchor point to be detected and the anchor point institute to be detected
The gas station POI points included in region to be detected are matched, and at least one primary election for determining the anchor point to be detected adds
After petrol station POI point, also include：
If the berthing time length of the anchor point to be detected is less than very first time length or more than the second time span,
Determine that the anchor point to be detected is not gas station POI points.
Exemplarily, very first time length and the second time span are refueled the average time of stop according to vehicle in gas station
Arrange.Very first time length is more than the second time span.Preferably, very first time length is 3min, and the second time span is 1h.
Vehicle is not to refuel to stop in the time that gas station stops too short or long stop, and the berthing time of anchor point to be detected is long
Degree is less than very first time length or more than the second time span, it is determined that the anchor point to be detected is not gas station POI points, by
This improves the accuracy with the gas station POI points of stop Point matching to be detected.
