[0030] The present disclosure is further described in detail below in conjunction with the accompanying drawings and examples. It is understood that the specific examples described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0031] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] Points of interest play a vital role in modern electronic map applications, improving the user experience and making maps not only a navigation tool, but also an information-rich platform that provides a full range of services and support. Whether in daily life or travel, POIs provide great convenience and help to users. When the map zoom level is low, the displayed area is large, which may cause multiple POIs to overlap and some POIs to be covered; or when in high-density POI areas such as city centers or commercial areas, POIs are densely distributed, which may also cause some POIs to overlap. Overlapping POIs increase the difficulty for users to find the POIs they need, resulting in low POI search efficiency and poor user experience; and important POIs are covered, which may also cause users to miss key locations or fail to correctly identify the path.

[0033] Figure 1 A schematic flow chart of a method for displaying points of interest on an electronic map according to an embodiment of the present disclosure is shown.

[0034] refer to Figure 1 When the display system displays the points of interest to be displayed in response to the instruction of the target user, the method for displaying points of interest on the electronic map provided in this embodiment includes: Step S110, determining whether the points of interest to be displayed include multiple overlapping points of interest.

[0035] In some embodiments of the present disclosure, if it is determined through step S110 that a plurality of overlapping interest points are included, step S120 is executed; otherwise, step S199 is executed.

[0036] Step S120, obtaining overlapping relationships between multiple overlapping interest points.

[0037] Step S130: grouping the multiple overlapping interest points according to the overlapping relationship to obtain an interest point set.

[0038] Step S140, obtaining user data of the target user.

[0040] Step S160, obtaining the attribute weight corresponding to the preset attribute according to the attention degree corresponding to the preset attribute and the preset weight value grading standard.

[0041] Step S170, obtaining attribute values ​​of overlapping points of interest in the set of points of interest according to the contents of the overlapping points of interest in the set of points of interest; Step S180, weighting the attribute values ​​and attribute weights of the overlapping interest points in the interest point set to obtain the interest weights of the overlapping interest points in the interest point set.

[0044] In some embodiments of the present disclosure, the other points of interest in step S191 refer to points of interest in the corresponding point of interest set except the current overlapping point of interest.

[0045] Step S192, obtaining a second occlusion area of ​​the overlapping interest point that is jointly occluded by at least two of the other interest points.

[0046] Step S193, obtaining the blocked area of ​​the overlapping interest point according to the first blocked area and the second blocked area.

[0047] Step S194, obtaining the unobstructed area of ​​the overlapping interest point according to the obstructed area.

[0050] Step S197, dividing the area weighted value by the total weighted area to obtain the transparency of the overlapping interest points.

[0051] Step S198, stacking and displaying the overlapping interest points in the interest point set according to the display level and transparency of the overlapping interest points in the interest point set.

[0052] Step S199, displaying the points of interest to be displayed according to a preset display mode.

[0053] Combined with the following Figures 2 to 10 The method for displaying points of interest on an electronic map disclosed in the present invention is described in detail.

[0054] Embodiment 1: Figure 2 The present invention is a flowchart of a method for displaying points of interest on an electronic map according to an embodiment of the present invention.

[0055] refer to Figure 2 The method M200 for displaying points of interest on an electronic map of this embodiment includes: Step S210: for a plurality of overlapping interest points among the interest points to be displayed, obtaining an interest point set corresponding to the plurality of overlapping interest points.

[0056] In some embodiments of the present disclosure, the overlapping points of interest in step S210 refer to multiple points of interest with the same or similar geographic coordinates, and as the map scale is reduced, their symbols or marks are very close to each other or even overlap on the map. Overlapping points of interest usually appear in dense urban areas or places with a large number of points of interest. The larger the map scale, the smaller the displayed area, the richer the details of the map, and the distances between the points of interest are more dispersed in a larger space, so the number of overlapping points of interest is small; the smaller the map scale, the larger the displayed area, the fewer details of the map, and the density of the points of interest marked on the map increases, so the number of overlapping points of interest is large; that is, a group of points of interest may not overlap when the map scale is large, but may overlap when the map scale is small.

[0057] Step S220: acquiring a display hierarchy of overlapping points of interest in the point of interest set according to the user data of the target user.

[0058] In some embodiments of the present disclosure, step S220 may determine the display level by obtaining a display priority score, a display weight, etc. according to user data.

[0059] Step S230: stacking and displaying the overlapping interest points in the interest point set according to the display hierarchy of the overlapping interest points in the interest point set.

[0060] The target user is the user who instructs the display of the points of interest to be displayed.

[0061] The electronic map point of interest display method provided by the present disclosure displays overlapping points of interest in a point of interest set according to the display hierarchy of overlapping points of interest. Since the display hierarchy is related to user data, and user data can reflect the user's preferences and needs, the electronic map point of interest display system can consider user needs when displaying points of interest, realize personalized display, reduce the difficulty of users finding the required POIs, and facilitate users to find key locations, thereby improving search efficiency; the system solves the problem in the prior art that when the map is scaled to a certain ratio, multiple POIs may overlap, resulting in the POIs of interest to the user being covered, resulting in a poor user experience. In addition, the point of interest set can simplify the display of points of interest on the map and reduce interference and confusion.

[0062] In some embodiments of the present disclosure, Figure 3 As shown, the method of obtaining a set of points of interest through step S210 may include: step S211, obtaining the overlapping relationship of multiple overlapping points of interest; step S212, grouping the multiple overlapping points of interest according to the overlapping relationship to obtain a set of points of interest. The overlapping relationship in step S211 refers to the situation where two or more points of interest have a common part or intersection. For different map scales, the overlapping relationship is different. The grouping according to the overlapping relationship in step S212 can be specifically to regard a certain point of interest and the points of interest overlapping with the point of interest as a set of points of interest; taking the example that point of interest A overlaps with points of interest B and C, and point of interest D overlaps with points of interest C and E, points of interest A, B and C can be regarded as a set of points of interest, and points of interest D, C and E as another set of points of interest. In particular, in order to improve the acquisition speed, step S210 can also be to obtain a set of points of interest corresponding to multiple overlapping points of interest from a preset first database; the method of obtaining the data stored in the preset first database is similar to step S211 and step S212; the data stored in the preset first database can be grouped according to the map scale; when acquiring data, the corresponding data can be obtained from the preset first database according to the current map scale.

[0063] In some embodiments of the present disclosure, in order to facilitate users to see multiple points of interest at the same time, for any set of points of interest, such as Figure 4 As shown, the process of displaying the interest points through step S230 may include: step S231, obtaining the blocked area of ​​the overlapping interest points in the interest point set; step S232, obtaining the transparency of the overlapping interest points in the interest point set according to the blocked area and interest weight of the overlapping interest points in the interest point set; step S233, stacking and displaying the overlapping interest points in the interest point set according to the display level and transparency of the overlapping interest points in the interest point set. Among them, for any overlapping interest point in the interest point set, such as Figure 5As shown, step S231 may include: step S2311, respectively obtaining the first occlusion area of ​​the overlapping interest point blocked by other interest points one by one; step S2312, obtaining the second occlusion area of ​​the overlapping interest point blocked by at least two other interest points; step S2313, obtaining the occluded area of ​​the overlapping interest point according to the first occlusion area and the second occlusion area. The occlusion area of ​​steps S2311 and S2312 can be calculated based on the shape of the graph; the other interest points in steps S2311 and S2312 are interest points in the interest point set other than the overlapping interest point. When obtaining the occluded area in step S2313, only the second occlusion area is counted once; assuming that the areas of interest points A, B, and C are all 100, the first occlusion area of ​​C blocking A is 30, the first occlusion area of ​​B blocking A is 15, and the second occlusion area of ​​A, B, and C is 5, then the occluded area of ​​interest point A is 30+15-5=40.

[0064] For any overlapping interest point in the interest point set, such as Figure 6 As shown, step S232 may include: step S2321, obtaining the unobstructed area of ​​the overlapping interest points in the interest point set according to the obstructed area; step S2322, weighting the unobstructed area and interest weight of the overlapping interest points in the interest point set to obtain the total weighted area of ​​the interest point set; step S2323, multiplying the unobstructed area of ​​the overlapping interest point by the interest weight of the overlapping interest point to obtain the area weighted value of the overlapping interest point; step S2324, dividing the area weighted value by the total weighted area to obtain the transparency of the overlapping interest point. Step S2321 may be specifically to subtract the obstructed area from the total area of ​​each interest point to obtain the unobstructed area. Step S2322 may be specifically to multiply the unobstructed area of ​​each overlapping interest point by the corresponding interest weight to obtain the weighted value; weighted processing is performed according to the weighted values ​​of all overlapping interest points in the interest point set to obtain the total weighted area.

[0065] Assume that there are three interest points A, B and C, whose interest weights are 53, 101.5 and 70 respectively, and whose unobstructed areas are 50, 80 and 60 respectively. Then the area weighted value of A is 53*50=2650, the area weighted value of B is 101.5*80=8120, the area weighted value of C is 70*60=4200, and the total weighted area is 2650+8120+4200=14970. Therefore, the transparency of A is 2650 / 14970=0.177, the transparency of B is 8120 / 14970=0.542, and the transparency of C is 4200 / 14970=0.281.

[0066] In some embodiments of the present disclosure, Figure 7As shown, the method for displaying points of interest on an electronic map provided by the present disclosure may further include, before step S210, step S240, determining whether the points of interest to be displayed include multiple overlapping points of interest. When it is determined by step S240 that the points of interest to be displayed include multiple overlapping points of interest, step S240 is executed. Figure 8 As shown, the method may also include: step S250, if not included, displaying the interest points to be displayed according to a preset display mode. Step S250 means that the interest points to be displayed are not modified or processed, but are directly displayed in the most original and basic form. Among them, step S240 may be to use an overlap detection method to determine whether the interest points to be displayed include multiple overlapping interest points; the overlap detection method includes: bounding box detection method, scan line algorithm, pixel level detection method, convex hull detection method, bitmap detection method, grid method, area filling algorithm or rotating caliper method; step S240 may also be to use a pre-trained learning model to determine whether the interest points to be displayed include multiple overlapping interest points; the learning model may be a machine learning model (such as a support vector machine model SVM, a decision tree / random forest model, etc.), a deep learning model (such as a convolutional neural network model CNN, etc.). When step S240 determines overlap, the range occupied by the point of interest can be calculated by the longitude and latitude of the point of interest; taking the point of interest displayed as a rectangle as an example, the actual distance to be moved in the up and down directions and the actual distance to be moved in the left and right directions can be determined based on the longitude and latitude of the center of the point of interest, and then the offset value of the longitude and latitude is calculated based on the actual distance, and finally the longitude and latitude values ​​of the four vertices are determined based on the offset value of the longitude and latitude.

[0067] In some embodiments of the present disclosure, step S240 uses a bounding box detection method to determine whether multiple overlapping interest points are included based on the boundary, such as determining whether and and and ; if yes, it includes multiple overlapping interest points; otherwise, it does not exist. for The left border of for The right boundary of for The upper boundary of for The lower boundary of for The left border of for The right boundary of for The upper boundary of for The lower boundary of and are two bounding boxes.

[0068] In some embodiments of the present disclosure, Fig. 9 As shown, step S220 may include: step S221, obtaining the interest weights of overlapping interest points in the interest point set according to the user data of the target user; step S222, obtaining the display hierarchy of overlapping interest points in the interest point set according to the interest weights of overlapping interest points in the interest point set. Fig.10 As shown, step S221 may include: step S2211, obtaining user data of the target user; step S2212, obtaining attribute weights corresponding to preset attributes according to the user data of the target user; step S2213, obtaining attribute values ​​of overlapping interest points in the interest point set according to the contents of overlapping interest points in the interest point set; step S2214, performing weighted processing on the attribute values ​​and attribute weights of overlapping interest points in the interest point set to obtain interest weights of overlapping interest points in the interest point set. Among them, the process of obtaining attribute weights through step S2212 may include: firstly, performing data analysis on the user data of the target user to obtain the attention corresponding to the preset attribute; and then obtaining the attribute weights corresponding to the preset attribute according to the attention corresponding to the preset attribute and the preset weight value grading standard. Among them, data analysis can include one or more of data cleaning and preprocessing, exploratory analysis, correlation analysis, cluster analysis and sentiment analysis; user data can include one or more of user basic information, user social attributes, user interests and hobbies, user consumption habits, user behavior (such as historical search records, click behavior, etc.), device information and geographic location information; preset attributes can be related to points of interest, such as when the points of interest are related to housing sources, the preset attributes can be price, room type, floor, etc.; the weight value classification standard is the weight value corresponding to different levels, such as the weight value corresponding to the advanced level is 5, the weight value corresponding to the intermediate level is 3, the weight value corresponding to the low level is 1, etc., and the weight value and classification method can be set as needed. For example, the attributes include price (weight a) and floor (weight b), the attribute value corresponding to the price is c, and the attribute value corresponding to the floor is d. If the weighted processing in step S2214 is specifically weighted summation, the interest weight obtained in step S2214 can be a*c+b*d.

[0069] It is understandable that before using the technical solutions disclosed in the embodiments of the present disclosure, the types, scope of use, usage scenarios, etc. of user data involved in the present disclosure should be informed to the user and the user's authorization should be obtained in an appropriate manner in accordance with relevant laws and regulations.

[0070] For example, when overlapping points of interest need to be displayed, a prompt message is sent to the user to clearly prompt the user that the operation requested to be performed will require obtaining and using the user's personal information. Thus, the user can independently choose whether to provide personal information to software or hardware such as an electronic device, application, server or storage medium that performs the operation of the technical solution of the present disclosure according to the prompt message.

[0071] As an optional but non-limiting implementation, the prompt information may be sent to the user in a pop-up window, in which the prompt information may be presented in text form.

[0074] In some embodiments of the present disclosure, the display level in step S220 refers to the way in which the points of interest are displayed in a certain order, that is, the corresponding points of interest are displayed at which layer. For example, if the display level of point of interest A is 1 layer, the display level of point of interest B is 2 layers, and the display level of point of interest C is 3 layers, then when the points of interest are displayed, point of interest A is displayed at the top layer, point of interest B is displayed below point of interest A, and point of interest C is displayed below point of interest B.

[0075] If the points of interest to be displayed include both overlapping points of interest and non-overlapping points of interest, the overlapping points of interest may be displayed through steps S210 to S230, and the non-overlapping points of interest may be directly displayed.
