Specific embodiment
Exemplary embodiments of the present disclosure are described in more detail below with reference to accompanying drawings.Although showing the disclosure in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
It is limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
It is fully disclosed to those skilled in the art.
The embodiment of the present invention provides a kind of method of determining vehicle operation distance, as shown in Figure 1, which comprises
Step 101: in the running region comprising two target locations, determining more than one for characterizing geographical location
Anchor point.
Step 102: being directed to each target location, closed according to the position between the target location and the anchor point
System determines target anchor point corresponding with the target location.
Step 103: being directed to each target location, determine the target between the target location and the target anchor point
Distance.
Step 104: according to the planning driving path between all target ranges determined and two target anchor points, really
Vehicle operation distance between fixed two target locations.
It should be noted that needing to know the vehicle between any two target location to determine optimal vehicle route
Operation distance, vehicle operation distance include that vehicle starts the time and/or vehicle starts mileage.Vehicle is between two target locations
Traveling will certainly have a driving starting point and a driving terminal, therefore, the vehicle operation distance between two target locations
Namely from driving starting point to the vehicle operation distance driving terminal.
For step 101, the running region in the application is the region comprising two target locations, the running region
Any delimitation can be carried out according to actual needs.For example, if two target locations are respectively positioned in a ring, it can be by a ring institute
The region for including is as running region, and the region that can also included using two rings is as running region.The model that running region delimited
It encloses bigger, it is determined that the quantity of the anchor point gone out is more, and then the target anchor point determined is more accurate, and the vehicle finally determined is opened
Row distance is more accurate.Further, if the region for being included using a ring is as running region, then, in the region that a ring is included
Interior determining anchor point, if the region for being included using two rings as running region, then, in the region that two rings are included determine anchor
Point.
For further, anchor point is used to characterize the geographical location in a certain place.Anchor point includes that Point Code and longitude and latitude are believed
Breath.Point Code is to the customized unique identification in place, and latitude and longitude information includes the longitude and latitude in the place.For how
Determine anchor point, the application provides following implementation:
Firstly, obtain running region logistics distribution data, logistics distribution data include more than one place and with ground
The corresponding dispatching frequency of point.Then, logistics distribution data are based on, the place that the frequency is more than default frequency threshold value will be dispensed and be determined as
Anchor point.
Specifically, in logistics distribution process, a dispatching record can be had by dispensing each time all, dispatching record packet
The place containing dispatching can obtain logistics distribution data by accumulation dispatching record, logistics distribution data include several places and
The dispatching frequency corresponding with each place.For example, the logistics distribution data of running region include the place A and the place B, and, A
The dispatching frequency of point is that the dispatching frequency in the place 50, B is 60.Further, a default frequency threshold value is set to the dispatching frequency, this is pre-
If frequency threshold value can also be referred to as cold threshold, the dispatching frequency is more than that the place of default frequency threshold value can also be referred to as hot topic
Place.By comparing the dispatching frequency in each place and default frequency threshold value, it is capable of determining that whether each place belongs to
In popular place, in turn, popular place is determined as anchor point by the application.For example, default frequency threshold value is 55, due to the place B
Dispensing the frequency has been more than 50, then the place B is determined as anchor point, which includes the Point Code in the place B and the longitude and latitude in the place B
Spend information.
It should be noted that anchor point can also derive from third party's data platform, third party's data platform is determined
Popular place as anchor point, thus, in this application, after determining running region, directly from third party's data platform
Import the anchor point being located in running region.For example, using the popular place in third party's navigation platform as anchor point.
For further, since each anchor point only represents one place, and certain area coverage can not be accurately characterized
Interior condition of road surface, therefore, for anchor point, there are corresponding anchor point region, anchor point region is the area centered on anchor point
Domain can be regular polygon, or round.Preferably, anchor point region is the border circular areas centered on anchor point, round
Region can equably characterize the condition of road surface around anchor point, thus improve the vehicle operation distance of acquisition to a certain extent
Accuracy.
Therefore, in this application, after determining that more than one is used to characterize the anchor point in geographical location, and in determining and mesh
Before marking the corresponding target anchor point in place, respectively centered on each anchor point, preset length is radius, establishes circular anchor point area
Domain.Wherein, an anchor point is corresponding with an anchor point region.The radius in anchor point region is longer, then accuracy is lower, anchor point region
Radius is shorter, then accuracy is higher, and the vehicle operation distance finally obtained is more accurate.In turn, in a step 102, according to target
Positional relationship between place, anchor point and anchor point region determines target anchor point corresponding with target location.
For each anchor point region, there are trusted area and insincere region, trusted area is that traveling confidence level is super
The region of default believability threshold is crossed, insincere region is the region for travelling confidence level and being no more than default believability threshold, credible
Area attribute vehicle can be by the region, can not be by the region, for example, the area road without trusted area characterization vehicle
It constructs or there are the obstructions such as river.
For how to determine trusted area and insincere region in anchor point region, in this application, firstly, by anchor point area
Domain is radial centered on anchor point to be divided into N equal portions, forms N number of region, and N is the integer more than or equal to 2.Then, according to every
The operation distance on two boundaries in a region, and maximum corresponding with the anchor point region can communication distance, by opening for two boundaries
Row distance be all larger than it is maximum can communication distance region as insincere region, remaining region is as trusted area.
A specific example is given below to how determining that trusted area and insincere region be described in detail.
As shown in Fig. 2, the radius in anchor point o corresponding anchor region is 700m, by anchor point region radial minute centered on o point
Be segmented into 8 equal portions, be respectively region s1os2, region s2os3, region s3os4, region s4os5, region s5os6, region s6os7,
Region s7os8 and region s8os1.Calculate the angle in each region, and according to calculated above-mentioned angle, anchor point o longitude and latitude,
The radius length and earth radius in anchor point region calculate the intersection point of N number of direction (8 directions) and anchor point edges of regions
Longitude and latitude, that is, calculate the longitude and latitude of s1, s2, s3, s4, s5, s6, s7 and s8.Due to calculating the longitude and latitude of above-mentioned eight points
Process is the prior art, and details are not described herein again.After the longitude and latitude for obtaining above-mentioned intersection point, obtain from each intersection point to anchor point,
And from anchor point to the vehicle operation distance each intersection point, that is, the vehicle operation distance from s1 to o and from o to s1, from
S2 to o and the vehicle operation distance from o to s2, and so on, start until obtaining the vehicle from s8 to o and from o to s8
Distance.It is analyzed by the round-trip range data to N number of point (8 points), calculating maximum can communication distance.Maximum can communication distance
Calculation formula is distance [n*3/4]+1.5* (distance [n*3/4]-distance [n*1/4]).Wherein, an anchor point
Region is corresponding there are a maximums can communication distance.For example, when N is 8, the round-trip range data of 8 points totally 16, respectively to 16
Data is numbered, and in one embodiment, the round-trip range data number on same boundary is adjacent, and, adjacent boundary
Round-trip range data it is adjacent, for example, for Fig. 2, with os1 for first range data, counter clockwise direction number sorting,
Then s1o is Article 2 range data, and os2 is Article 3 range data, and s2o is Article 4 range data, and os3 is Article 5 distance
Data, s3o are Article 6 range data and so on, and os8 is Article 15 range data, and s8o is Article 16 range data.
For further, distance represents an array, if it is the 12nd article of range data that N, which is 8, distance [n*3/4],
Distance [n*1/4] is the 4th article of range data.Wherein, it is maximum can communication distance be according to the median probability in statistics point
Cloth principle simultaneously combines practical business contextual data to obtain by machine learning.
Obtaining maximum can judge respectively whether the vehicle operation distance on two boundaries in above-mentioned zone is equal after communication distance
Greater than maximum can communication distance, if the vehicle operation distance on two boundaries be all larger than maximum can communication distance, which is determined as
Insincere region, otherwise, the region are trusted area.For example, if the distance of os1 and os2 are big for the s1os2 of region
In maximum can communication distance, then region s1os2 be insincere region, insincere region shadow representation.
It should be noted that for anchor point and anchor point region, it may be predetermined that and be stored in caching.
For further, in practice, since roading is frequently not straight line, and there are traffic lights and special road conditions
Etc. factors influence, there may be very big differences for spherical surface longitude and latitude distance and actual vehicle operating range between two target locations
Not.Therefore, for trusted area, there are trusted area multiplying powers, can be to vehicle as weight by trusted area multiplying power
Operating range is accomplished, to be modified to spherical surface longitude and latitude distance, to improve accuracy.Trusted area multiplying power is according to region
Trust boundary vehicle operation distance and the anchor point region where trusted area all trust boundaries vehicle start away from
From acquisition.Wherein, trust boundary is the boundary that the right and left on boundary is trusted area, and insincere boundary is the left and right on boundary
At least there is the boundary in an insincere region in both sides.For a trusted area, may there is only a trust boundary,
May also two boundaries be trust boundary.
Specifically, the multiplying power of the trusted area is equal to trust boundary in the trusted area for a trusted area
Average traffic operation distance divided by the average traffic of all trust boundaries in the anchor point region where the trusted area start away from
From.For example, in Fig. 2, the multiplying power of region s2os3 are as follows: os3/ ((os3+os4+os5+os6+os7+os8)/6), region s3os4
Multiplying power are as follows: (os3+os4)/2)/((os3+os4+os5+os6+os7+os8)/6).
For how according to the positional relationship between target location, anchor point and anchor point region, determination is corresponding with target location
Target anchor point, the application provides following specific embodiments:
First, it is determined that whether there is anchor point in the predetermined detection area comprising target location, it, will in figure in conjunction with diagram
Predetermined detection area is represented by dashed line, and target location is A point, and anchor point is indicated with M point.If anchor is not present in predetermined detection area
Point, as shown in figure 3, then using target location as target anchor point, that is, using A point as target anchor point.If predetermined detection area memory
In anchor point, and target location covers anchor point, as shown in figure 4, then using the anchor point of target location covering as target anchor point, that is, by K
Point is used as target anchor point, herein, since K point and A point are overlapped, accordingly it is also possible to using A point as target anchor point.If default detection
There are anchor points in region, and target location does not cover anchor point, as shown in figure 5, then making anchor point existing in predetermined detection area
For benchmark anchor point, that is, using K point as benchmark anchor point, if there are multiple anchor points in predetermined detection area, multiple anchor points are made
For benchmark anchor point.In turn, judge whether target location falls into the trusted area in the benchmark anchor point region of benchmark anchor point, wherein base
The corresponding anchor point region of quasi- anchor point is benchmark anchor point region.
For further, the trusted area in the benchmark anchor point region of benchmark anchor point whether is fallen into for target location, is existed
Three kinds of situations below: in the first scenario, if target location only falls into the trusted area in a benchmark anchor point region, such as Fig. 6
It is shown, then using the corresponding benchmark anchor point of the trusted area as target anchor point, i.e., using K point as target anchor point.In second of feelings
Under condition, if target location falls into the trusted area in multiple benchmark anchor points region, as shown in fig. 7, existing in predetermined detection area
Anchor point K1 and K2, K1 and K2 are benchmark anchor point, and A point falls into the trusted area in the anchor point region of benchmark anchor point K1, meanwhile, A point
Also fall into the trusted area in the anchor point region of benchmark anchor point K2, then benchmark anchor corresponding to the trusted area fallen into target location
The nearest benchmark anchor point in point mid-range objectives place is as target anchor point, that is, for benchmark anchor point K1 and benchmark anchor point K2,
Since K2 point distance A point linear distance is nearest, using K2 point as target anchor point.In a third case, if target location
The trusted area in benchmark anchor point region is not fallen within, as shown in figure 8, certainly, the case where for not falling within trusted area, not only
The case where including the anchor point region for not falling within benchmark anchor point, the also insincere region comprising falling into the anchor point region of benchmark anchor point
The case where, then using target location as target anchor point, that is, using A point as target anchor point.
It should be noted that in this application, if two target locations are respectively A point and B point, then respectively by above-mentioned
Process determines target anchor point A ' corresponding with A point, and determines target anchor point B ' corresponding with B point.
After determining target anchor point, in step 103, determine target between target location and target anchor point away from
From.For how to determine that target range, the application provide the mode of being implemented as follows:
Judge whether target location and target anchor point are same point, if target location and target anchor point are same point, mesh
Subject distance is zero, that is, in the case of figure 3, in the case shown in figure 4 and in the case of figure 8, due to upper
Stating three kinds of situations can be using target location as target anchor point, therefore, in these three cases, target location and target anchor point
Between target range be 0.
In addition, if target location and target anchor point are difference: being established centered on target anchor point includes target location
Target anchor point region inside is based on target anchor using the intersection point between planning driving path and target anchor point region as region point of contact
Put confidence region belonging to the distance between the distance between region point of contact, target anchor point and target location and target location
The multiplying power in domain obtains fuzzy distance of the target location relative to target anchor point, using fuzzy distance as target range.
Specifically, the process comprising the target anchor point region including target location is established centered on target anchor point, with
The aforementioned process for establishing anchor point region is identical, the difference is that only that radius length need to be greater than when establishing target anchor point region
The distance between target location and target anchor point, so that target location can be made to be located in target anchor point region.Further, it ties
The planning driving path between two target anchor points is closed, the planning driving path between two target anchor points can pass through third party's map application
It gets, planning driving path namely guidance path.After determining the planning driving path between two target anchor points, by planning driving path
Intersection point between target anchor point region is as region point of contact, as shown in figure 9, for target location A, corresponding target
Anchor point is A ', and the planning driving path between target anchor point A ' and target anchor point B ' is r, the target of planning driving path r and target anchor point A '
Region point of contact between anchor point region is Q.For how to determine the coordinate of region point of contact Q, detailed description given below:
