本发明实施例涉及电子地图技术领域，尤其涉及一种兴趣点信息展示方法、装置、服务器和存储介质。Embodiments of the present invention relate to the technical field of electronic maps, and in particular, to a method, device, server and storage medium for displaying point-of-interest information.
背景技术Background technique
随着计算机技术的发展，电子地图的发展也愈发迅速。电子地图是指利用计算机技术，以数字方式存储和查阅的地图。With the development of computer technology, the development of electronic map is also more and more rapid. Electronic maps refer to maps that are stored and consulted digitally using computer technology.
在电子地图的制作过程中，需要将兴趣点(Point of Interest，POI)数据标注在电子地图中。随着电子地图技术的快速发展，越来越多的POI可标注于地图当中，便于用户浏览和查找有用的信息，但同时多个距离较近甚至重叠的POI又为用户对信息的查找带来了不必要的麻烦。因此现有技术中，依据两两POI之间的相互遮盖关系来确定POI处于显示状态或隐藏状态，两者择其一进行展示，即展示处于显示状态的POI标注，而隐藏处于隐藏状态的POI标注。In the process of making an electronic map, point of interest (POI) data needs to be marked on the electronic map. With the rapid development of electronic map technology, more and more POIs can be marked on the map, which is convenient for users to browse and find useful information. unnecessary trouble. Therefore, in the prior art, it is determined whether the POI is in the display state or the hidden state according to the mutual covering relationship between two POIs, and one of the two is selected for display, that is, the POI label in the display state is displayed, and the POI in the hidden state is hidden. label.
然而，现有技术的POI展示方式可应用的范围较小，当电子地图处于某种不可预计的缩放状态时所展示的POI标注信息之间仍然存在相互交叠的现象。且随着用户对于电子地图的缩放，展示出来的POI标注信息存在反复切换和变更的现象，导致地图显示较为零乱，且POI标注信息显示不够完善，降低用户浏览和查找有用地图信息的用户体验。However, the applicable scope of the POI display method in the prior art is small, and when the electronic map is in a certain unpredictable zoom state, there is still a phenomenon of mutual overlap between the displayed POI label information. And as the user zooms in on the electronic map, the displayed POI labeling information is repeatedly switched and changed, resulting in a messy map display, and the display of POI labeling information is not perfect, reducing the user experience of browsing and finding useful map information.

实施例一Embodiment one
图1为本发明实施例一提供的一种兴趣点信息展示方法的流程图，本实施例可适用于电子地图在当前可视区域中展示POI标注区域的情况，该方法可由一种兴趣点信息展示装置来执行。该方法具体包括如下步骤：Figure 1 is a flow chart of a method for displaying POI information provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where an electronic map displays POI marked areas in the current visible area. The method can be composed of a POI information Demonstration means to perform. The method specifically includes the following steps:
S110、确定当前可视地图区域中所包括的各兴趣点在终端屏幕上的兴趣点标注区域。S110. Determine the point-of-interest labeling area of each point of interest included in the current visible map area on the terminal screen.
在本发明具体实施例中，当前可视地图区域是指在终端的当前地图显示界面中，依据用户搜索或调整后所确定的地图显示区域。可以理解的是，在用户进行搜索后，地图通常会采用默认的显示比例进行地图的显示；在用户对地图进行缩放操作后，放大后的可视地图区域相对能够显示的地图范围较小，但可显示的地点更详细；反之，缩小后的可视地图区域相对能够显示的地图范围较大，但可显示的地点较为粗略。进而在用户通过搜索或调整而确定地图显示区域后，依据终端屏幕的尺寸和目标位置确定当前可视地图区域，当前可视地图区域包含目标位置。具体的，可以根据POI在地图中的经纬度坐标来确定该POI在屏幕中的坐标，依据终端屏幕的尺寸即屏幕的长和宽、地图当前显示的比例尺或分辨率以及目标POI在屏幕中的坐标来确定当前可视地图区域。In a specific embodiment of the present invention, the current visible map area refers to the map display area determined after searching or adjusting by the user in the current map display interface of the terminal. It is understandable that after the user performs a search, the map usually uses the default display scale to display the map; after the user zooms the map, the zoomed-in visible map area is relatively smaller than the map that can be displayed, but The locations that can be displayed are more detailed; on the contrary, the zoomed-out viewable map area is larger than the range of the map that can be displayed, but the locations that can be displayed are relatively rough. Furthermore, after the user determines the map display area by searching or adjusting, the current visible map area is determined according to the size of the terminal screen and the target position, and the current visible map area includes the target position. Specifically, the coordinates of the POI on the screen can be determined according to the latitude and longitude coordinates of the POI on the map, according to the size of the terminal screen, that is, the length and width of the screen, the scale or resolution currently displayed on the map, and the coordinates of the target POI on the screen to determine the current visible map area.
本实施例中，POI是指地图上能够进行特定活动的机构、系统组织设施或场所，包括宾馆、餐饮、购物、风景名胜、商务住宅、政府机关、社会团体、企事业单位、科教文化、汽车服务、交通设施、金融保险等种类。POI标注区域是地图渲染中用于显示POI相关信息的要素，即POI标注区域是指用于显示POI相关信息的显示区域。在电子地图上可以以任何形状和排列方式进行显示。通常情况下，各POI标注可以包括图标标注和文字标注，且标注通常位于关联的POI的旁边，以对POI进行相关的解释或说明，便于用户对POI的浏览和查找。本实施例对当前可视地图区域进行处理，依据当前可视地图区域中包括的各POI的图标标注和/或文字标注，同时动态获取当前可视地图区域的分辨率，以此确定图标标注的像素和/或文字标注的像素。依据图标标注的像素和/或文字标注的像素来确定POI标注区域的大小，并以POI标注区域的中心点坐标值确定为该POI标注区域的位置坐标。进而依据POI标注区域的大小和位置坐标，确定各POI在终端屏幕上的POI标注区域。In this embodiment, POI refers to institutions, system organization facilities or places that can carry out specific activities on the map, including hotels, restaurants, shopping, scenic spots, commercial residences, government agencies, social groups, enterprises and institutions, science and education culture, automobiles, etc. Services, transportation facilities, finance and insurance, etc. The POI label area is an element used to display POI-related information in map rendering, that is, the POI label area refers to a display area used to display POI-related information. It can be displayed in any shape and arrangement on the electronic map. Normally, each POI annotation may include icon annotation and text annotation, and the annotation is usually located next to the associated POI, so as to explain or explain the POI, so as to facilitate users to browse and find the POI. In this embodiment, the current visible map area is processed, and the resolution of the current visible map area is dynamically acquired according to the icon label and/or text label of each POI included in the current visible map area, so as to determine the icon label Pixels and/or pixels for text labels. The size of the POI marked area is determined according to the pixels marked by the icon and/or the pixels marked by the text, and the coordinates of the center point of the marked POI area are determined as the position coordinates of the marked POI area. Further, according to the size and position coordinates of the POI marking area, the POI marking area of each POI on the terminal screen is determined.
示例性的，假设用户搜索餐厅A，终端以默认比例尺对包含餐厅A的地图区域进行显示，进而依据当前终端屏幕的尺寸、地图当前显示的比例尺或分辨率以及餐厅A在屏幕中的坐标来确定当前可视地图区域。同时可以将当前可视地图区域中的餐厅A以及其他餐厅均作为POI，动态获取当前显示界面的分辨率，依据各POI的图标标注和/或文字标注以及分辨率，确定各POI的图标标注的像素和/或文字标注的像素，从而依据各POI的图标标注的像素和/或文字标注的像素确定各POI标注区域的大小和位置坐标，即明确了各POI标注区域。Exemplarily, assuming that the user searches for restaurant A, the terminal displays the map area containing restaurant A at the default scale, and then determines the size of the map based on the size of the current terminal screen, the scale or resolution of the map currently displayed, and the coordinates of restaurant A on the screen. The currently visible map area. At the same time, restaurant A and other restaurants in the current visual map area can be used as POIs to dynamically obtain the resolution of the current display interface, and determine the icon labeling of each POI according to the icon label and/or text label and resolution of each POI Pixels and/or text marked pixels, so that the size and position coordinates of each POI marked area are determined according to the icon marked pixels and/or text marked pixels of each POI, that is, each POI marked area is defined.
S120、依据各兴趣点标注区域之间的相互遮盖关系确定各兴趣点标注区域所属的遮盖分组。S120. Determine the covering group to which each POI labeling area belongs according to the mutual covering relationship between each POI labeling area.
在本发明具体实施例中，POI标注区域之间的相互遮盖关系是指至少两个POI的POI标注区域存在重叠的现象，则POI标注区域中被遮盖的部分将无法正常显示，影响用户对该POI信息的获取。本实施例可以预先设定遮盖比例阈值，即当两个POI标注区域的重叠区域与两个POI标注区域的面积比例高于该遮盖比例阈值时，则确定所述两个POI标注区域之间具有相互遮盖关系。In a specific embodiment of the present invention, the mutual covering relationship between POI labeling areas refers to the phenomenon that the POI labeling areas of at least two POIs overlap, and the covered part in the POI labeling areas will not be displayed normally, affecting the user's understanding of the POI labeling area. Acquisition of POI information. In this embodiment, the coverage ratio threshold can be preset, that is, when the area ratio between the overlapping area of two POI labeling areas and the two POI labeling areas is higher than the coverage ratio threshold, it is determined that there is a gap between the two POI labeling areas. Mutual coverage relationship.
本实施例对具有相互遮盖关系的POI标注区域进行分组，其中遮盖分组中可以仅存在一个POI标注区域，或者，遮盖分组存在满足遮盖关系的两个POI标注区域，或者遮盖分组中存在多余两个的POI标注区域，且其中必然存在至少一个POI标注区域与该遮盖分组中的其他至少两个POI标注区域具有相互遮盖关系。因此对于一个待分组的POI标注区域，若该待分组的POI标注区域与任意遮盖分组中的至少两个POI标注区域具有相互遮盖关系，则确定该待分组的POI标注区域与该遮盖分组具有相互遮盖关系。In this embodiment, POI labeling areas with a mutual covering relationship are grouped, wherein there may be only one POI labeling area in the covering group, or there may be two POI labeling areas satisfying the covering relationship in the covering group, or there may be more than two POI marking regions in the covering group. POI marked areas, and there must be at least one POI marked area that has a mutual covering relationship with at least two other POI marked areas in the covering group. Therefore, for a POI labeling area to be grouped, if the POI labeling area to be grouped has a mutual covering relationship with at least two POI labeling areas in any cover group, then it is determined that the POI labeling area to be grouped has a mutual covering relationship with the cover grouping. cover up the relationship.
相应的，本实施例依据待分组的POI标注区域与遮盖分组之间的相互遮盖关系，确定待分组的POI标注区域的所属遮盖分组。本实施例考虑到各POI标注区域的遮盖关系是随着地图的缩放而发生变化的，因此优选根据以下原则进行遮盖分组的确定：若待分组的POI标注区域与至少两个遮盖分组具有相互遮盖关系，则将该至少两个遮盖分组进行合并，并确定该待分组的POI标注区域属于合并后的遮盖分组；若待分组的POI标注区域与一个遮盖分组具有相互遮盖关系，则确定该待分组的POI标注区域属于该遮盖分组；此外，若待分组的POI标注区域与已有的遮盖分组均没有相互遮盖关系，则生成新的遮盖分组，并将该待分组的POI标注区域归属到该新生成的遮盖分组中。Correspondingly, in this embodiment, according to the mutual covering relationship between the POI marking areas to be grouped and the covering groups, the covering groups to which the POI marking areas to be grouped belong are determined. In this embodiment, considering that the coverage relationship of each POI labeling area changes with the zooming of the map, it is preferable to determine the cover grouping according to the following principle: if the POI labeling area to be grouped and at least two cover groups have mutual cover relationship, then merge the at least two cover groups, and determine that the POI labeling area to be grouped belongs to the combined cover group; if the POI label area to be grouped has a mutual cover relationship with a cover group, then determine that the grouping The POI labeling area belongs to the cover group; in addition, if the POI label area to be grouped has no mutual cover relationship with the existing cover group, a new cover group is generated, and the POI label area to be grouped belongs to the new cover group. In the generated mask group.
示例性的，在地图放大至最大时，当前可视地图区域中的各个POI相距较远，此时可能不会产生POI标注区域相互遮盖的情况，可以视为每个POI标注区域为一个遮盖分组。相应的，随着地图的逐渐缩小，当前可视地图区域中的POI标注区域可能逐渐产生相互遮盖的情况，进而根据上述遮盖分组原则，随即更新遮盖分组。Exemplarily, when the map is zoomed in to the maximum, the POIs in the current visible map area are far apart. At this time, the POI labeling areas may not cover each other, and each POI labeling area can be regarded as a cover group . Correspondingly, as the map gradually shrinks, the POI marked areas in the current visible map area may gradually cover each other, and then according to the above covered grouping principle, the covered groups are updated immediately.
S130、从各遮盖分组中选择兴趣点标注区域进行展示，并隐藏各遮盖分组中未被选择的兴趣点标注区域。S130. Select the POI labeling area from each masking group to display, and hide the POI labeling area not selected in each masking group.
在本发明具体实施例中，由于遮盖分组中可能存在多个POI，同时由于遮盖分组中的POI标注区域是存在相互遮盖关系的，因此为了避免多个POI遮盖区域同时显示而产生的互相遮盖现象而导致信息显示不完整，本实施例对各个遮盖分组中的POI进行选择，择其一进行展示，而隐藏其余未被选中的POI标注区域。In the specific embodiment of the present invention, since there may be multiple POIs in the cover group, and because the POI labeling areas in the cover group have a mutual cover relationship, in order to avoid the mutual cover phenomenon caused by the simultaneous display of multiple POI cover areas As a result, the display of information is incomplete. In this embodiment, POIs in each cover group are selected, and one of them is selected for display, while the marked areas of the remaining unselected POIs are hidden.
本实施例预先对地图中各POI进行权重的计算，依据各遮盖分组中包括的各POI权重，选择权重最大的POI进行POI标注区域展示。其中，本实施例可以根据各POI的详情数据、评星等级以及用户评价等信息来计算各POI的权重，且依据一定的时间规则对各POI的权重进行更新。此外，将其余未被选中即权重较低的POI对应的POI标注区域进行隐藏处理，避免了与所属遮盖分组中已展示的POI标注区域的相互遮盖。但在各遮盖分组中所展示的POI标注区域处还展示各遮盖分组中所隐藏的POI数量，或者同时展示各遮盖分组中所隐藏的POI数量以及类型。In this embodiment, the weight of each POI in the map is calculated in advance, and according to the weight of each POI included in each cover group, the POI with the largest weight is selected for POI labeling area display. In this embodiment, the weight of each POI can be calculated according to information such as the detailed data of each POI, star ratings, and user evaluations, and the weight of each POI can be updated according to a certain time rule. In addition, the POI labeling areas corresponding to the remaining unselected POIs with lower weights are hidden, so as to avoid mutual covering with the displayed POI labeling areas in the covered group. However, the number of hidden POIs in each covered group is also displayed at the marked area of the POI displayed in each covered group, or the number and type of POIs hidden in each covered group are displayed at the same time.
值得注意的是，本实施例通过对具有遮盖关系的POI标注区域的分组，选择权重最大的POI标注区域进行展示，隐藏遮盖分组中的其余POI标注区域，并显示隐藏的POI数量。由于同一时刻的POI权重是不会发生变化的，因此保证了电子地图在缩放过程中，权重较大的POI标注区域对于权重较小的POI标注区域的遮盖关系是不会发生变化的。进而随着电子地图的缩放，所展示的隐藏的POI数量会一致性的发生变化，而不会同时存在数量增加和数量减小的现象，避免了所展示的POI标注区域反复切换和变更的问题。It is worth noting that in this embodiment, by grouping POI marked areas with covering relationship, the POI marked area with the largest weight is selected for display, the remaining POI marked areas in the covered group are hidden, and the number of hidden POIs is displayed. Since the POI weight at the same moment will not change, it is guaranteed that the covering relationship between the POI labeling area with a larger weight and the POI labeling area with a smaller weight will not change during the zooming process of the electronic map. Furthermore, with the scaling of the electronic map, the number of hidden POIs displayed will change consistently, without the phenomenon of increasing and decreasing numbers at the same time, avoiding the problem of repeated switching and changing of the displayed POI labeling area .
示例性的，图2为POI信息展示的示例图。如图2所示，当前可视地图区域中包括三个POI：A、B和C，其权重由高至低排序为A、C和B，即兴趣点A的权重最高，其次为兴趣点C的权重，而兴趣点B的权重最低。在三个场景中，图2由上至下电子地图发生了缩小操作，即地图(2)由地图(1)缩小而成，地图(3)由地图(2)缩小而成，进而POI由三个互不干预的POI逐渐发生了重叠现象。右侧一列的地图分别为左侧一列的地图依据本实施例所述的兴趣点信息展示方法所行为的地图显示情况。其中，由于地图(1)未发生遮盖现象，进而三个POI能够独立显示。而地图(2)中的兴趣点B和C之间具有相互遮盖关系，由于兴趣点C的权重高于兴趣点B的权重，进而选择兴趣点C进行展示，同时展示出该遮盖分组内POI的数量即2。而地图(3)中的兴趣点B不仅和C之间具有相互遮盖关系，还与兴趣点A之间具有相互遮盖关系，相应的兴趣点A、B和C可以作为一个遮盖分组，且由于兴趣点A的权重最高，进而选择兴趣点A进行展示，同时展示出该遮盖分组内POI的数量即3。由此可知，根据权重的大小，地图(3)中遮盖于兴趣点B的POI由兴趣点C变为兴趣点A。而本实施例避免了当遮盖于兴趣点B的POI发生变化时，所展示的POI仍然存在相互遮盖的现象，且避免了同时存在展示的POI数量增加和数量减小的现象。Exemplarily, FIG. 2 is an example diagram showing POI information. As shown in Figure 2, the current visible map area includes three POIs: A, B, and C, and their weights are ranked as A, C, and B from high to low, that is, point of interest A has the highest weight, followed by point of interest C The weight of interest point B is the lowest. In the three scenarios, the electronic map in Figure 2 is zoomed out from top to bottom, that is, the map (2) is zoomed out from the map (1), the map (3) is zoomed out from the map (2), and then the POI is zoomed out from the three The overlapping of POIs that do not interfere with each other gradually occurs. The maps in the right column are respectively the map display status of the maps in the left column according to the method for displaying information on points of interest described in this embodiment. Wherein, since the map (1) is not covered, the three POIs can be displayed independently. In the map (2), points of interest B and C have a mutual covering relationship. Since the weight of point of interest C is higher than that of point of interest B, point of interest C is selected for display, and at the same time, the POI in the covered group is displayed. The quantity is 2. In the map (3), point of interest B not only has a mutual covering relationship with point C, but also has a mutual covering relationship with point of interest A. The corresponding points of interest A, B and C can be used as a covering group, and because of The weight of point A is the highest, and then the point of interest A is selected for display, and the number of POIs in the covered group is displayed, which is 3. It can be seen that, according to the size of the weight, the POI covered by the point of interest B in the map (3) changes from the point of interest C to the point of interest A. However, this embodiment avoids the phenomenon that the displayed POIs still cover each other when the POI covered by the point of interest B changes, and avoids the phenomenon that the number of displayed POIs increases and decreases at the same time.
本实施例的技术方案，通过确定当前地图可视区域中各个POI的标注区域，并分析各个POI标注区域之间的相互遮盖关系，对具有遮盖关系的POI标注区域进行分组，从而从各个遮盖分组中选择POI标注区域进行展示，而隐藏各遮盖分组中其他未被选择的POI标注区域。本发明实施例通过对具有遮盖关系的POI标注区域的所属的遮盖分组的划分，能够将当前地图可视区域中POI的整体情况及其细节信息清楚的展示给用户，解决了地图展示信息过多导致用户无法看清内容的问题，以及避免了电子地图缩放过程中展示出来的POI标注信息反复切换和变更导致地图显示零乱的问题，提高了地图POI信息展示的完整性和细节信息的突显性，进而提高用户对于电子地图的使用体验。In the technical solution of this embodiment, by determining the marked areas of each POI in the visible area of the current map, and analyzing the mutual covering relationship between the marked areas of each POI, the marked areas of POIs with covering relations are grouped, so that each covered grouping Select the POI labeling area to display, and hide other unselected POI labeling areas in each mask group. The embodiment of the present invention can clearly display the overall situation and detailed information of the POI in the current map visible area to the user by dividing the covered grouping of the POI marked area with a covered relationship, and solves the problem of excessive information displayed on the map. The problem that the user cannot see the content clearly, and the problem that the POI label information displayed during the zooming process of the electronic map is avoided repeatedly switching and changing, which leads to the problem of messy map display, improves the integrity of the map POI information display and the prominence of detailed information. Thereby, the user's experience of using the electronic map is improved.
