Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

The value determination method of the POI collection areas is mainly used for determining which collection areas have higher collection values, so that reference is provided for subsequent designation of POI collection tasks of field workers or for publishing compensated POI collection tasks on the network, collection routes of collection tasks or the number of published tasks are optimized, and the cost of POI collection is reduced. In view of the above, the specific method for determining the value of the acquisition area according to the present invention is shown in fig. 1, and includes:

step 101, POI and road information to be collected contained in a target collection area are obtained.

The target acquisition area is a geographical area which is divided in advance based on an electronic map, and the specific division standard is not specifically limited in this embodiment, for example, division is performed according to an administrative area, or division is performed based on a grid in the electronic map. In practical applications, the purpose of dividing the collection area is to collect POIs more effectively, and according to the distribution rule of the POIs (multiple positions are located on two sides of a road), a common collection area division mode is based on road division, that is, a road is used as a boundary for distinguishing the collection area, and because road network information in an electronic map is relatively fixed and accurate, the obtained target collection area is relatively stable.

When the acquisition regions of the POI are divided by roads, any two acquisition regions do not overlap with each other, and the roads serving as the dividing boundaries belong to the roads of the two acquisition regions respectively. In this step, the road information refers to all roads and related information in the acquired target acquisition area, such as the grade (such as highways, national roads, city main roads, etc.), names, widths, etc., of the roads, among the POI to be acquired and road information contained in the acquired target acquisition area; the POI to be collected refers to the POI which exists in a target collection area and needs secondary collection, the POI is generally the POI which has problems found after the first collection, the problems may be inaccurate positioning or overlapping with other POI positions, and the POI information is wrong or incomplete, so that the POI with the problems needs secondary collection to determine whether the POI is marked in an electronic map or not after the POI is determined to be relevant information.

And 102, determining a road section in the target acquisition area according to the road information.

The step is to process the acquired road information and determine the road section in the target acquisition area. Generally, when a road in the target collection area is obtained, the road often does not fall into the collection area completely, but a part of the road is located in the collection area, and in the process of collecting POIs, the POIs are associated with specific road sections in the road, so that the step needs to further determine road sections contained in the target collection area according to road information.

Generally, if a road belongs to a plurality of acquisition regions, the step needs to determine the boundary intersection point of the road and the target acquisition region when being executed, and since the boundary of the target acquisition region in this embodiment is mostly a road, the end point of the road section can be determined by the intersection point between roads, and then the road section located in the target acquisition region is determined. It should be noted that, in one target collection area, the same road may be divided into a plurality of road segments, for example, the road segments may be divided according to the direction of the road. That is, there may be multiple road segments of multiple roads in the target acquisition area.

And 103, determining the position association relationship between the road section and the POI to be collected.

The position association relationship is used for acquiring the relationship between the road section and the POI to be acquired, namely one POI is acquired through a certain road section, and then the POI and the road section are determined to have the position association relationship. In practical application, the position association relationship may be determined by comparing the position of the road segment with the position of the POI to be collected, for example, comparing the shortest distance between the POI and each road segment, determining the road segment with the smallest distance as having the position association relationship with the POI, and determining whether there is an independent building between the position of the POI and each road segment, if not, determining that there is the position association relationship between the POI and each road segment, where the method for determining the position association relationship is not specifically limited in this embodiment.

The purpose of this step is to determine the number of POIs to be collected associated with a road segment in the target collection area, and generally, it is considered that the more POIs to be collected associated with the same road segment, the higher the collection value of the road segment is. For the target acquisition area, the more high-value road sections the target acquisition area contains, the greater the acquisition value of the acquisition area is.

And 104, analyzing the position association relation by using a preset strategy, and determining a POI acquisition value index of the target acquisition area.

The position association relation is a main evaluation parameter in a preset strategy, and comprehensive evaluation of the target acquisition area can be realized through the preset strategy. In practical application, the preset strategy can be adjusted according to actual needs, for example, the area of the acquisition area which cannot be bought, the total number of road sections, the total number of POIs to be acquired and the like can be used as parameters participating in evaluation, so that the acquisition cost required for carrying out POI acquisition on the target acquisition area, namely the POI acquisition value index, can be evaluated.

It can be seen from the specific implementation manner in the above embodiment that, in the method for determining the value of the POI acquisition area provided in the embodiment of the present invention, the POI to be acquired and the road information in the target acquisition area are utilized, the acquisition result obtained after the POI acquisition is performed on the target acquisition area is analyzed for value evaluation, and the value of the acquisition result is quantized to obtain a POI acquisition value index, so that the transverse comparison of a large number of target acquisition areas is realized, the POI acquisition is preferentially performed on the high-value target acquisition area, and meanwhile, the cost accounting for performing the POI acquisition on the target acquisition area can be optimized based on the POI acquisition value index, so as to realize selective task delivery, thereby integrally reducing the cost of POI acquisition.

In order to further explain the value determination method of the POI collection area in detail, the determination and application of the position association relationship between the road section and the POI to be collected are specifically explained. The specific content is shown in fig. 2, and includes:

step 201, POI and road information to be collected contained in the target collection area are obtained.

This step is the same as step 101 in fig. 1, and details are not repeated.

It should be noted that the obtained POI to be collected refers to a POI that can be obtained by field staff through outdoor collection, for example, a company in an office building can only obtain the office building through outdoor collection and cannot shoot the company, and the POI corresponding to such a company does not belong to the POI to be collected in this embodiment.

Step 202, acquiring a road according with a preset road grade according to the road information, and determining a road section of the road in the target acquisition area.

The step is to extract road grades of corresponding roads from road information and filter the roads in the target collection area by using preset road grades, and the purpose of the step is to filter some roads with lower grades, such as the same roads, paths and the like, because POI exists around the roads and is difficult to collect POI through the roads. The screening can reduce the number of roads to be processed in the target acquisition area and reduce the calculation amount of data processing.

For roads meeting preset road grades, the length of the roads is generally longer, and the roads can span a plurality of target acquisition areas, so that the roads need to be broken into the roads according to the range of the target acquisition areas, and road sections contained in the target acquisition areas are determined.

And step 203, determining the position association relationship between the road section and the POI to be collected.

Specifically, in this embodiment, each road segment in the target collection area is abstracted, each road segment is abstracted into a road segment, and the direction of the road segment is determined. The significance of this operation is: when the POI is collected based on the road, it is generally required that the collection person collects the street view picture of the left side or the right side of the road, and for a wider road (such as a bidirectional driving road), when the collection person travels along the left side of the road and travels along the right side of the road, the determined left side of the road cannot accurately define the direction to be shot.

In addition, abstracting the road section into the road segment is also beneficial to determining the position association relationship between the road section and the POI to be collected. This is because the position association relationship mainly depends on the distance from the position of the POI to be collected to the road segment, and when the road segment is abstracted as a road segment, the distance can be determined more accurately without considering the width of the road segment itself. Therefore, the POI to be collected and which road route segment have the association relationship can be more accurately determined. It should be noted that, in this embodiment, one POI to be collected is associated with one road segment, and therefore, in practical application, a target road segment associated with each POI to be collected is determined first, and then, the number of POIs to be collected associated with each road segment is counted.

Further, for a road segment, the POI to be collected associated with the road segment may be distributed on both sides of the road segment, and when collecting different POIs, it is necessary to inform the collecting personnel which side of the road segment is collected to obtain the POI to be collected. Therefore, it is necessary to determine the direction to be acquired based on the direction of the road segment defined above. When the position association relationship between the road section and the POI to be collected is determined, the determination is also based on the direction, and generally, the position association relationship between the POI to be collected and the road section defines that the POI to be collected is located on the left (right) side of the road section, and the left (right) side is determined relative to the direction of the defined road segment.

And 204, analyzing the position association relation by using a preset strategy, and determining a POI acquisition value index of the target acquisition area.

A specific implementation manner of this step in this embodiment is as follows:

firstly, the number of POI to be collected having position association relation with a road section is obtained. The number refers to the number of POIs to be collected on the same side of the road section, that is, for the same road section, two number values are obtained, namely, the number of POIs on the left side of the road and the number of POIs on the right side of the road.

And secondly, determining the road section average acquisition weight value of the target acquisition area according to the number. The road section average acquisition weight value is the ratio of the road section average acquisition number in the target acquisition area to the sum of the road section average acquisition numbers of all the acquisition areas. The average collection number of road sections refers to an average value of the number of POIs to be collected associated with the road sections in one target collection area. Therefore, the road section average acquisition weight value is used for measuring the proportion of the road section acquisition quantity of the target acquisition area in all the acquisition areas, and the higher the weight value is, the higher the acquisition value of the target acquisition area is.

And finally, calculating the POI acquisition value index of the target acquisition area by utilizing the road section average acquisition weight value.

When the POI collection value index is calculated, the preset strategy in this embodiment processes the road average collection weight value used, and further performs comprehensive evaluation by using the collection weight value of the POI to be collected and the value weight value of the target collection area.

The collecting weight value of the POI to be collected is used for evaluating the collecting demand degree of the POI to be collected, and generally, each POI to be collected is provided with a corresponding importance index for determining the severity of the problem of the POI to be collected or the urgency degree of the collecting demand, for example, the index is classified into an urgent need index, an important index, a general index and the like. In the target acquisition area, the higher the importance index of the POI to be acquired is, the greater the value of the target acquisition area is.

The value weight of the target acquisition area is used for evaluating the position importance degree of the target acquisition area, and the value weight can be determined by the area and the geographic position of the target acquisition area, for example, the larger the area is, the more POIs contained in the target acquisition area are, the less POIs are required to be acquired in the unit area, and the corresponding weight value is lower than the weight value of the target acquisition area with the smaller area; the geographic location mainly considers the importance of the target acquisition area, for example, the closer the location of the target acquisition area is to the city center, the higher the weight value is.

The POI collection value index of the target collection area is comprehensively calculated by obtaining the weight values, the specific mode is not limited, and the purpose of determining the POI collection value index by adopting a plurality of weight values is to comprehensively evaluate the target collection area from a plurality of dimensions, so that the POI collection value index can more accurately reflect the collection value of the target collection area.

Further, the method for determining the value of the POI capturing area shown in fig. 2 is mainly to process and evaluate a target capturing area, and in practical applications, a large number of target capturing areas generally need to be processed simultaneously, and a target capturing area with a high bid value is selected from the target capturing areas to perform a corresponding POI capturing task. According to the process, as for a single target acquisition area, the processed road information is not related to the POI to be acquired and data in other target acquisition areas, so that in the embodiment of the invention, each target acquisition area can be used as a processing task, the POI acquisition value indexes of a plurality of target acquisition areas are processed simultaneously by using a distributed system, and then the target acquisition area with the POI acquisition value index larger than the threshold value is selected to generate a corresponding POI acquisition task. Or selecting a preset number of target acquisition areas from high to low according to the sequence of the POI acquisition value indexes, and generating a corresponding POI acquisition task. And finally, performing acquisition operation on POI to be acquired at the specified position by field personnel or network users according to the POI acquisition tasks. Therefore, a large number of target acquisition areas are processed in batches through the distributed system, the processing efficiency can be greatly improved, and the high-value target acquisition areas needing to be acquired can be obtained more quickly.

Further, as an implementation of the methods shown in fig. 1 and fig. 2, an embodiment of the present invention provides a value determining device for a POI acquisition area, where the device is configured to determine an acquisition value of the POI acquisition area by using information of POIs, roads, and the like contained in the acquisition area, so as to generate an acquisition task in the POI acquisition area with a high value and push the acquisition task to a user, optimize delivery of the POI acquisition task, and reduce acquisition cost.
