The invention provides a method for displaying interest points, which comprises the following steps: acquiring at least two POIs matched according to the search words and characteristic information of the at least two POIs; generating an annotation of each POI, wherein the attribute of the annotation is used for indicating the characteristic information of each POI; and displaying the label of each POI.
Wherein the property of the annotation comprises at least one of transparency, color, shape, and size.
The marking factor value comprises at least one of service, user score, price, actual distance between the POI and the positioning point, user comment number, environment and preference information number.
Wherein the annotation factor value comprises a ranking factor value for the at least two POIs.
Fig. 2 is a flowchart illustrating a preferred embodiment of the method for displaying a point of interest according to the present invention, and as shown in fig. 2, the preferred embodiment comprises the following steps:
step S201, at least two POIs matched according to the search term and feature information of the at least two POIs are obtained.
Specifically, the client receives a search term input by the user, and then sends the search term and the coordinate range of the current view to the server.
The server obtains all POIs in the current view range from the database according to the coordinate range of the current view, and then matches the POIs according to the received search words to obtain POIs corresponding to the search words in the current view range; meanwhile, after the server obtains the matched POIs, the server extracts the feature information of the POIs from the database and sends the POIs and the feature information of the POIs to the client.
And the feature information of the POI is a marking factor value of each marking type corresponding to at least two POIs.
The annotation type comprises a sequencing type, such as sequencing according to service, sequencing according to user scores, sequencing according to prices, sequencing according to actual distances between POI and positioning points, sequencing according to the number of comments of users, sequencing according to environments, sequencing according to the number of preferential information and the like.
Correspondingly, the labeling factor value comprises a sorting factor value, and the sorting factor value comprises: the system comprises at least one of service, user score, price, actual distance between the POI and the positioning point, user comment number, environment and preference information number.
Step S202, generating an annotation of each POI, wherein the attribute of the annotation is used for indicating the characteristic information of each POI.
Specifically, a client receives at least two POIs and characteristic information of the at least two POIs in a current view range from a server, wherein each POI comprises a name, a category and longitude and latitude coordinates, the client can determine the position of each POI according to the longitude and latitude coordinates, then determine the position of each POI on an electronic map, and finally set a preset picture at the position of each POI on the electronic map, wherein the picture set on the electronic map can be used as a mark of the POI to represent the position of each POI in the electronic map, so that the POI can be marked on the electronic map; for example, a water drop-shaped picture is used as a mark of the POI in a hundred-degree map application, and a circular picture is used as a mark of the POI in a soso map application.
After the client sets a picture on the electronic map, the attribute of the label of the POI needs to be configured according to the feature information of the POI, so that the drawing tool can draw the label according to the configured attribute when drawing the map, the attribute of the drawn label can indicate the feature information of the POI, the client can display the feature difference between the POIs, and the user can know the feature difference between different POIs in the current sorting type according to the displayed attribute.
Wherein the attributes of the label include: at least one of transparency, color, shape, size.
The invention takes the example that the attribute of the label is transparency, and explains the method for generating the label of each POI by the client:
first, the client obtains marking factor values of at least two POIs according to received feature information of the POIs, sorts the POIs according to the obtained marking factor values in a descending order of the marking factor values, and generates a corresponding sorting sequence number for each POI according to a sorting result, for example, as shown in fig. 3, A, B, C is used as a sorting sequence number, or 1, 2, and 3 are used as sorting sequence numbers.
And the client acquires the maximum marking factor value from the sequencing result of the POI.
Secondly, the client calculates the transparency of the label of each POI according to the labeling factor values of at least two POIs, the preset maximum transparency and the maximum labeling factor value by using the following formula:
m = M × x X max
in the formula, M represents the transparency of the label of the POI, M represents the opacity value in the preset maximum transparency, the transparency value in the maximum transparency is 0, X represents the value of the labeling factor of the POI, and X represents the value of the labeling factor of the POImaxRepresenting the maximum annotated factor value; and the transparency corresponding to the maximum marking factor value is the maximum transparency M.
Finally, the client configures the sequence number of the POI and the transparency of the mark of the POI through a configuration interface provided by a drawing tool; for example, the calculated transparency of the label of the POI is input to a transparency control function preset in the drawing tool as a function value of the transparency control function.
The client calls the drawing tool to draw the electronic map, when the drawing tool draws the electronic map, the marking of the POI is drawn according to the configured sequence number of the POI, the transparency control function is called when the marking of the POI is drawn, and the marking of the POI is drawn according to the transparency input in the transparency control function.
And step S203, displaying the label of each POI.
Specifically, as shown in fig. 3, the client displays, in the electronic map, a label of the POI in the current view range of the user search term, where the label of the POI has different transparency determined by the feature information of the POI, and therefore, when there is a difference between the transparency of the label of the POI and the transparency of the labels of other POIs, the user can see the difference, so as to determine the difference of the feature information of the POI according to the difference of the transparencies, for example, the difference of services, the difference of prices, the difference of actual distances between the POI and a location point, the difference of user evaluations, and so on.
In order to implement the above method, the present invention provides a system for displaying a point of interest, fig. 4 is a schematic structural diagram of a preferred embodiment of the system for displaying a point of interest, as shown in fig. 4, the system includes: a processing unit 41, a display unit 42; wherein,
