Detailed Description

Exemplary embodiments of the present application will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present application are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 is a flow chart of an information delivery method according to an embodiment of the present application. The embodiment can be applied to the situation that the target screen point position is determined to put the towed information. Typically, the embodiment can be applied to the situation that the screen point positions are reasonably determined according to the objective and accurate geographical position of the screen point positions and the crowd flow thermodynamic diagram and the attention area determined by the dispenser, and the release information is displayed. The information delivery method disclosed in the present embodiment may be performed by an information delivery apparatus, which may be implemented by software and/or hardware. Referring to fig. 1, the information delivery method provided in this embodiment includes:

S110, in the electronic map, a focus area of the user is determined according to the interactive operation.

The interaction operation may be an interaction operation between the presenter and the device displaying the electronic map, for example, the device displays the electronic map to the presenter, and the presenter realizes the interaction operation with the device through an operation on a screen of the device. The attention area is used for reflecting information delivery place trends and demands of the deliverers. The presenter can perform a circling operation or a clicking operation on the electronic map to determine the attention area.

Optionally, determining the attention area of the presenter according to the interactive operation includes: acquiring POIs selected by a presenter in an electronic map; a circular area centered on the selected POI is taken as the region of interest. As shown in fig. 2 and 3, the presenter can determine a POI (Point of Interest ) in the electronic map by inputting or clicking through a search box, and set a preset length as a radius with the POI as a center to determine a circular area as a region of interest. The preset length can be set according to actual conditions so as to meet the requirement of a user on the information delivery area. The round area determined by the POI selected by the user is used as the attention area, so that the operation of a user is facilitated, the attention area is determined according to the requirement of the user, and the shape of the attention area is normalized, so that candidate screen points in the attention area can be determined conveniently.

Optionally, after taking the circular area centered on the selected POI as the region of interest, the method further includes: and adjusting the size of the region of interest in response to a boundary drag operation on the circular region.

Because the function of dragging the circular boundary cannot be realized in the external API of the current electronic map, in the embodiment of the application, a brand new view control is created through the self-defined interactable circular view, so that clicking and dragging of a circular area are realized, the operation of a user is facilitated, and the accuracy of determining the concerned area is improved.

S120, taking the screen points belonging to the attention area as candidate screen points.

Specifically, because the attention area is determined according to the interactive operation of the presenter, the attention area can reflect the area requirement and trend of the presenter to put information, and therefore, according to the specific positions of the screen points, the screen points belonging to the attention area are determined as candidate screen points, so that the presenter can conveniently determine the target screen points meeting the conditions according to the candidate screen points.

Optionally, taking the screen points belonging to the region of interest as candidate screen points includes: inquiring the screen point positions in the attention area based on the geocoding index, and taking the inquired screen point positions as candidate screen point positions; the geocode is an integer number obtained by splicing longitude codes and latitude codes of screen points.

Illustratively, for a screen dot location, its longitude code and latitude code are determined, the longitude code is left shifted, and an or operation is performed with the latitude code, for example, the resulting longitude code is 1011 1001 0011 0100 0110, the latitude code is 1101 0010 1010 1010 0101, and the longitude is left shifted: 1011 1001 0011 0100 0110 0000 0000 0000 0000 0000, performing or operation with dimension coding results in a geocode of 1011 1001 0011 0100 0110 1101 0010 1010 1010 0101. Compared with a mode of generating the geocode by cross insertion, the shift and/or operation coding mode in the embodiment of the application does not need to accurately search the cross inserted coding bits, has high operation efficiency, does not need to perform Base32 coding operation, and can reduce coding time consumption. In addition, in the process of searching according to the geocoding of integer numbers, the hashCode method and the equality method are less in time consumption, so that the time required by searching is saved, and the searching efficiency is improved.

Optionally, the display modes of different screen points can be determined under different scales of the electronic map. For example, as shown in fig. 4, if the scale is smaller than 500 meters, the current display area corresponds to a building, and a screen point belonging to the building is displayed. As shown in fig. 5, if the scale is 500-2000 meters, the current display area corresponds to the business district, and the screen points in the business district are displayed. As shown in fig. 6, if the scale is greater than 2000 meters, the current display area corresponds to an urban area, and the screen points in the urban area are displayed.

S130, displaying the crowd flow thermodynamic diagram of the region of interest.

The crowd flow thermodynamic diagram is used for reflecting the people flow distribution at a certain position and presenting the people flow density at a geographic position. As shown in fig. 7, areas with different people flow densities are represented by different colors to visually represent people flow in the different areas. According to the embodiment of the application, the crowd flow thermodynamic diagrams of the concerned area are displayed, so that the crowd flow densities of different geographic positions are intuitively displayed, and a user can conveniently determine the geographic position where the information is required to be displayed according to the thermodynamic diagrams, so that the effective display of the information is facilitated. It should be noted that, the thermodynamic diagram in the region of interest may be displayed, or the thermodynamic diagram of the entire electronic map range may be displayed, so that the user may refer to the selection of the screen point location. In addition, the thermodynamic diagram can be displayed in any scene selected by the screen point, for example, the thermodynamic diagram can be displayed in the scene that the user clicks the screen point, the attention area is circled, the screen point is automatically displayed according to the scale, and the like, so as to provide the people flow information.

Optionally, before displaying the crowd thermodynamic diagram of the region of interest, the method further includes: responding to crowd screening operation, and acquiring crowd attribute information selected by a user; determining user flow information belonging to the attention area and conforming to the crowd attribute information; and constructing a thermodynamic diagram of the region of interest according to the determined user flow information.

Specifically, because the target audiences corresponding to different delivery information are different, for example, the target audiences corresponding to the delivery information of the personal care product class are females, and the target audiences corresponding to the delivery information of the graduate recruitment class are graduates, as shown in fig. 8, the crowd attribute options are shown for the delivery person, the crowd screening operation is performed by the delivery person, the user flow information conforming to the crowd attribute information in the concerned region is determined according to the crowd attribute information selected by the delivery person, and therefore a thermodynamic diagram is constructed according to the user flow information, so that the thermodynamic diagram fully reflects the flow of the target audiences in the concerned region, and the delivery information is shown by the delivery person in a more targeted manner at a screen point position with large flow of the target audiences.

And S140, acquiring a target screen point position selected from the candidate screen point positions according to the crowd flow thermodynamic diagram, and displaying the delivery information.

As shown in fig. 9, the candidate screen points include: the magnificent international mansion, the five-element bridge B seat and the supporting international mansion can be judged according to the displayed crowd flow thermodynamic diagram, and the magnificent international mansion is positioned in the area with large crowd flow, so that the magnificent international mansion can be used as a target screen point.

Alternatively, the thermal relevance of the screen points may be determined according to the following method:

wherein w is _k Weights representing screen points, k representing screen points, h _j Representing the thermal point, d (k,h _j ) The distance function is represented, n represents a constant parameter with fixed weight, and the larger the distance range is, the smaller the value of n is. And measuring the crowd thermal correlation degree of the screen points through the weight value summarization of the screen points so as to determine the target screen points from the candidate screen point summarization through the crowd thermal correlation degree of the screen points.

Optionally, before obtaining the target screen point selected from the candidate screen points according to the crowd flow thermodynamic diagram, the method further includes: responding to screen screening operation, and acquiring screen attribute information selected by a user and building attribute information of a building to which the screen belongs; and screening candidate screen points in the attention area according to the screen attribute information and the building attribute information.

For example, as shown in fig. 10, the screen attribute information and the building attribute information of the building to which the screen belongs may be displayed to the presenter so that the presenter can perform screening according to actual demands. The screen attributes may include, among other things, screen size, screen type, screen price, screen inventory, and the like. The building attribute information of the building to which the screen belongs may include: office buildings, residential buildings, malls, schools, and the like. The user can select proper screen attribute information and building attribute information according to the displayed screen attribute information and building attribute information of the building to which the screen belongs, so that different requirements of the user are met.

Optionally, after obtaining the target screen point selected from the candidate screen points according to the crowd flow thermodynamic diagram, the method further includes: and generating release request data according to the information of the target screen point positions, and sending a release request to a release system for indicating the release system to release.

As shown in fig. 11, the delivery request data is generated according to the selected target screen point location, an order is formed, and the order is sent to the delivery system to instruct the delivery system to deliver. By generating the release request according to the information of the target point location and indicating the release system to release, the problem of low efficiency and accuracy caused by manually generating the release request is avoided, the release information is effectively displayed according to the actual demands of the release person, and the reading effect and value of the release information are improved.
