Description

Technical Field

[0001] The invention relates to map information processing technology, and in particular to a method for presenting different parking lot information according to different zoom levels of a map. Background Art

[0002] With the popularization of smart devices and the widespread use of map applications, users' demands for map information are becoming more and more diverse. As one of the important geographic information in the map, the display method of parking lot information directly affects the user experience. Traditional parking lot information display methods usually use a fixed method to display all parking lot information. No matter what level the user zooms the map to, the displayed parking lot information is consistent. However, this display method will cause the parking lot information to be too dense and difficult to distinguish when the map zoom level is large; and when the map zoom level is small, it may not provide enough parking lot information, affecting the user's decision.

[0003] The prior art with application number 201710458138.X discloses a method for generating parking lot map data, the method comprising: determining one or more target parking lots for which map data is to be generated; the map data comprises contour surface data and / or entrance and exit data; for each target parking lot, identifying the contour surface of the target parking lot in the real-view map, marking the contour surface and adding one or more parking lot attributes to the contour surface to obtain the contour surface data of the parking lot; and / or, identifying one or more entrances and exits of the target parking lot in the real-view map, marking each entrance and exit and adding one or more entrance and exit attributes to each entrance and exit respectively to obtain the entrance and exit data of the parking lot; exporting the obtained map data of each target parking lot into a file of a specified format; the determining one or more target parking lots for which map data is to be generated comprises: reading basic information of one or more parking lots from a parking lot database, and taking each parking lot as a target parking lot; the basic information comprises one or more of the following: parking lot identification, parking lot abbreviation, parking lot full name, parking lot latitude and longitude, and parking lot entrance and exit information; the method further comprises: importing the basic information of the parking lot into the real-view map and converting it into map data of the corresponding parking lot.

[0004] The problem with the above prior art is that, although it can generate a map file containing parking lot contour data and entrance and exit data, it fails to dynamically adjust the displayed parking lot information according to the different zoom levels when the user views the map. Therefore, when the user uses the map, no matter how the zoom level changes, the displayed parking lot information is always the same, which cannot meet the needs of users in different situations. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a method for presenting different parking lot information according to different zoom levels of a map, aiming to improve the display effect of the parking lot information so that users can get the best usage experience at different zoom levels.

[0006] The method of the present invention comprises the following steps:

[0007] Collecting parking lot data, the parking lot includes on-street roadside parking lots and closed parking lots;

[0008] Using the parking lot data, presenting parking lot display information layers at different zoom levels and storing them in a database;

[0009] In response to a request from a user terminal, a parking lot information layer of a corresponding zoom level is retrieved from the database according to the current zoom level of the third-party map and is displayed superimposed on the third-party map.

[0010] Furthermore, the parking lot data includes information such as the parking lot location, parking lot longitude and latitude, and parking lot boundaries.

[0011] Furthermore, the presenting of parking lot display information layers at different zoom levels using the parking lot data includes filling the parking lot data into an online parking lot creation tool and presenting the data through a point, line, or surface method provided by a third-party map.

[0012] Furthermore, the remaining number of empty parking spaces can also be displayed on the parking lot information layer. The specific method includes: after the third-party map is initialized, it communicates with the parking lot management system through an interface, the parking lot management system updates the remaining number of empty parking spaces in real time, the remaining number of empty parking spaces is synchronized to the database, and in response to the user's request, the parking lot information layer of the corresponding level is retrieved according to the current zoom level, and the remaining number of empty parking spaces is displayed on the parking lot information layer.

[0013] Furthermore, the method also includes: obtaining a current third-party map zoom level value, and when the third-party map zoom level value is greater than a first zoom value, displaying a first parking lot information layer on the third-party map, wherein the parking lot is marked with a marked point on the first parking lot display information layer.

[0014] When the zoom level of the third-party map is greater than the second zoom value and less than the first zoom value, a second parking lot information layer is superimposed and displayed on the third-party map, and the closed parking lot on the second parking lot information layer is displayed as a parking lot range surface, and the on-road and off-road parking lots are displayed as presentation lines.

[0015] When the zoom level of the third-party map is less than the second zoom value, a third parking lot information layer is superimposed and displayed on the third-party map, the closed parking lot on the third parking lot information layer is displayed as a parking lot range surface and entrance and exit marking points are added to the parking lot range surface, and the roadside parking lot on the road displays each parking space surface.

[0016] Furthermore, the first parking lot information layer, the second parking lot information layer and the third parking lot information layer all display a remaining number of parking spaces identification, and the remaining number of parking spaces identification color displays different colors according to the ratio of the remaining number of parking spaces to the total number of parking spaces.

[0017] Furthermore, the method also includes, in response to a zoom operation of a third-party map of a user terminal, superimposing and displaying the first parking lot information layer, the second parking lot information layer and the third parking lot information layer on the third-party map in real time, and the first parking lot information layer, the second parking lot information layer and the third parking lot information layer can be displayed overlapping each other.

[0018] Further, when any of the first parking lot information layer, the second parking lot information layer and the third parking lot information layer covers other parking lot information layers, the covered parking lot information layer is cleared.

[0019] On the other hand, the present application provides a system for presenting different parking lot information according to different zoom levels of a map, the system comprising at least one processor; and a memory storing instructions, which, when executed by at least one processor, implements the steps of the method described in any one of claims 1-9.

[0020] The beneficial effects of the present invention are:

[0021] 1. Improve the pertinence of information display: At different zoom levels, users can see parking lot information with different levels of detail, avoiding the problem of information overload or insufficient information. For example, at a small zoom level, users can see the outline and entrances and exits of the parking lot, while at a large zoom level, users can see the distribution of the parking lot and the number of remaining parking spaces, so as to quickly find a suitable parking location. Enhance user experience: By dynamically adjusting the display of parking lot information, users can get a more intuitive and convenient experience when using the map. For example, when the user zooms out the map to view a larger range, the system will automatically hide some unimportant details and only display key information, allowing users to obtain the required information faster. Improve decision-making efficiency: When looking for parking spaces, users can quickly determine which parking lots have vacant parking spaces based on the current zoom level and parking lot information layer, thereby saving time and improving travel efficiency.

[0022] 2. Reduce data transmission volume: By displaying detailed parking lot information only when needed, the amount of data transmission can be reduced, the requirements for smart device performance can be reduced, and network resources can be saved. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Various aspects of the present disclosure will now be explained with reference to the accompanying drawings. As long as the shapes, relative positions and other aspects of the components described in these aspects are not clearly defined, the scope of the present disclosure is not limited to the components shown, which are only used for illustrative purposes. In addition, although many details are set forth, it should be understood that some aspects of the present disclosure can be implemented without these details. In other cases, well-known circuits, structures and technologies are not shown in detail to avoid obscuring the understanding of the description.

[0034] The present invention will be further described and illustrated below in conjunction with the embodiments of the present invention.

[0035] like Figure 1 As shown, a method for presenting different parking lot information according to different zoom levels of a map comprises the following steps:

[0036] S1 collects parking lot data, where the parking lot includes on-street roadside parking lots and closed parking lots;

[0037] Specifically, the parking lot data includes but is not limited to the parking lot location, parking lot longitude and latitude, parking lot boundaries, entrance and exit information, and the number of remaining empty parking spaces, etc. The parking lot data can be collected in a variety of ways, such as through vehicle-mounted GPS devices, mobile applications, manual inspections, or interfaces with urban traffic management systems.

[0038] S2 uses the parking lot data to present parking lot display information layers at different zoom levels and stores them in a database;

[0039] Specifically, in step S2, the process of presenting the parking lot display information layer at different zoom levels involves classifying and processing the collected parking lot data. First, the parking lot data is classified into different categories according to the type of parking lot (on-street roadside parking lot or closed parking lot) and scale. Then, using the API interface provided by the third-party map, the parking lot boundary, entrance and exit information is converted into graphic elements of points, lines, and surfaces.

[0040] Different display strategies are designed according to different zoom levels. For example, at a higher zoom level, the entrances and exits and boundary lines of the parking lot can be presented in detail so that users can clearly see the specific location and layout of the parking lot. At a lower zoom level, the parking lot can be simplified to a marked point, and the name of the parking lot and the number of remaining parking spaces are displayed to reduce visual complexity.

[0041] S3 responds to the request of the user terminal, retrieves the parking lot information layer of the corresponding zoom level from the database according to the current zoom level of the third-party map, and displays it in superposition with the third-party map.

[0042] In step S3, the system monitors the user's zoom operation on the third-party map in real time. When the user changes the zoom level, the system automatically retrieves the parking lot information layer corresponding to the current zoom level from the database. Then, the retrieved parking lot information layer is superimposed on the third-party map to ensure that the user can see the parking lot information that best matches the current view.

[0043] In some embodiments, Figure 2As shown, the use of the parking lot data to present parking lot display information layers at different zoom levels includes filling the parking lot data into an online parking lot creation tool and presenting it through point, line, and surface methods provided by a third-party map, and filling in relevant parking lot information when adding a new parking lot. Figure 2 In the parking lot information, the parking lot information includes "parking lot name", "parking lot abbreviation", "system developer", "city", "street", "business type", "person in charge", "related projects", "charging area", "parking lot number", "parking lot type", "department", "city", "nature of parking lot", "parking location", "person in charge's phone number", "remarks", "registration number" and other information. After filling in this information into the online parking lot creation tool, the parking lot information is presented through the point, line and surface methods provided by the third-party map, such as Figure 3 As shown, in this embodiment, the parking lot information can be directly presented using the location markers on the Amap. Figure 3 In the map, by clicking the icon, you can directly display the parking lot boundary line on the map, and you can also mark the center point, mark the entrance, mark the exit, etc.

[0044] In some specific embodiments, the parking lot information layer can not only display the location information of the parking lot, but also provide real-time data on the number of remaining empty parking spaces. The specific method for implementing this function is as follows: First, the third-party map will communicate with the parking lot management system through a specific interface during the initialization process. The parking lot management system will continuously monitor and update the number of remaining empty parking spaces in each parking lot. These real-time updated data will be synchronized to the database to ensure the accuracy of the information. When a user makes a request, the system will retrieve the parking lot information layer of the corresponding level according to the current zoom level. Then, the system will display the latest number of remaining empty parking spaces on the parking lot information layer, so that users can intuitively see the vacancy situation of each parking lot.

[0045] When a user requests a parking lot through a terminal, if the user requests a parking lot near him / herself, the user's location can be quickly located through the latitude and longitude information of the user's terminal, and the parking lot data contains the parking lot's latitude and longitude, and the parking lot list within 5 kilometers is displayed first according to the user's current geographic location. The system will calculate the distance between the user and each parking lot, and arrange them in order from near to far, and display the results on the map through the rendering method provided by the map, and return them to the user terminal. If the user searches for a parking lot near the destination, the system will also calculate and display the parking lot list within 5 kilometers of the destination based on the latitude and longitude information of the destination. In order to improve search efficiency, the system will pre-index the parking lot data to quickly retrieve the parking lot information related to the destination.

[0046] like Figure 5-Figure 9As shown, in some specific embodiments, the method also includes: obtaining the current third-party map zoom level value, and when the third-party map zoom level value is greater than the first zoom value, superimposing and displaying a first parking lot information layer on the third-party map, and the parking lot is marked with a marked point on the first parking lot display information layer.

[0047] When the zoom level of the third-party map is greater than the second zoom value and less than the first zoom value, a second parking lot information layer is superimposed and displayed on the third-party map, and the closed parking lot on the second parking lot information layer is displayed as a parking lot range surface, and the on-road and off-road parking lots are displayed as presentation lines.

[0048] When the zoom level of the third-party map is less than the second zoom value, a third parking lot information layer is superimposed and displayed on the third-party map, the closed parking lot on the third parking lot information layer is displayed as a parking lot range surface and entrance and exit marking points are added to the parking lot range surface, and the roadside parking lot on the road displays each parking space surface.

[0049] Specifically, in this embodiment, Figure 5-Figure 9 As shown in the figure, when the car owner uses the map to search for nearby parking lots: when the zoom level is 200 meters or above, all parking lots are marked with point P on the map.

[0050] When the zoom level is 100 meters and less than 200 meters, the closed parking lot is displayed as the parking lot range surface 1; on-road and off-road parking lots are displayed in the map as line 2.

[0051] For closed parking lots with a zoom level less than 100 meters, the entrance and exit marking points 3 are added on the basis of the presented range surface; for roadside parking lots on the road, each parking space surface 4 is presented;

[0052] In some implementations, the first parking lot information layer, the second parking lot information layer, and the third parking lot information layer all display the remaining parking lot number mark 5, and the remaining parking lot number mark color displays different colors according to the ratio of the remaining parking lot number to the total parking lot number. Specifically, as shown in the figure, it displays green when sufficient, orange when less, and red when tight.

[0053] The method also includes, in response to a zooming operation of a third-party map of a user terminal, overlaying and displaying the first parking lot information layer, the second parking lot information layer, and the third parking lot information layer on the third-party map in real time, and the first parking lot information layer, the second parking lot information layer, and the third parking lot information layer can be displayed overlapping each other.

[0054] Specifically, in some embodiments, the method for presenting a closed parking lot using Amap is as follows:

[0055] Specifically in some embodiments, the method of presenting a closed parking lot is:

[0056] Construct a "parking layer" function that receives an object as a parameter, which contains two properties: `map` and `AMap`. `map` is a map instance, and `AMap` is an API object of Amap (a popular Chinese map service provider). Initialize a layer that stores parking polygons and markers; render the deformation and markers on the map and display them on the map; display different layers according to the zoom level;

[0057] Specifically, in some embodiments, the method of presenting the closed parking lot entrance and exit icon is:

[0058] When the zoom level is less than 18 and greater than 15, the marker layer is hidden first, and then the parking lot polygon layer is displayed. If the zoom level is not within the above range, the code calls the method to hide all layers. Hide all layers, then clear all overlays and set both objects to null values.

[0059] In some embodiments, the method of presenting the roadside parking lot boundary line is:

[0060] First, check if the yard boundary line already exists. If not, create a new polygon layer object, which is a container for managing multiple overlays on the map (such as lines, markers, etc.). Next, the function iterates over the array of paths; - Convert the point coordinates in each path to an array. This conversion process is to determine the center point coordinates of the path by averaging the start and end coordinates of each path. - Create a new object using these center point coordinates. - Set several properties of the new object, including line width, line transparency, line color, and the connection style of the polyline inflection points if rounded. Add the created new object to the previously created `polygon layer` object. Finally, add the polygon layer to the map instance so that the lines will be displayed on the map.

[0061] In some embodiments, the method of presenting the parking lot entrance and exit icon is:

[0062] The function first checks whether the marker layer is undefined and whether the `longitude and latitude` attribute exists in the `path parameter. If both conditions are met, the operation of adding markers begins. Create a new `Amap` instance, which is named `marker layer`. Each element in the `path longitude and latitude` array selects a different icon URL according to the `point type` attribute. For each point, set the icon size and image source URL. If the `point type value` is 2, use a specific URL; if it is 3, use another URL; otherwise, use the first URL by default. Then create an `AMap.Marker` instance. The position of this marker is determined by the longitude and latitude of `i tem`. Set the offset and icon of the marker at the same time. 6. Add the created marker to the `marker layer` instance. Add the `marker layer` to the map;

[0063] In some embodiments, when any one of the first parking lot information layer, the second parking lot information layer and the third parking lot information layer covers other parking lot information layers, the covered parking lot information layer is cleared.

[0064] When the user performs a zoom operation, the display mode of the parking lot will switch between the first parking lot information map layer, the second parking lot information layer, and the third parking lot information layer to ensure that the user can get the best visual experience and information display at different zoom levels. The switching between the parking lot information layers is carried out by overlapping each other. If the covered parking lot is not cleaned up in time, it will be stacked in the system, resulting in display confusion and information redundancy. To avoid this situation, the system has designed a set of intelligent cleaning mechanisms. When the user performs a zoom operation, the system will automatically detect the current zoom level and determine which parking lot information layers need to be covered. Once the covering relationship is determined, the system will immediately clear the covered parking lot information layer to ensure the neatness of the display interface and the accuracy of the information, and release memory.

[0065] like Fig.10 As shown, the present application also provides a system for presenting different parking lot information according to different zoom levels of a map, wherein the system 10 includes at least one processor 101, a memory 102, an input device 103, and a display device 104, wherein the input device 103 is used to obtain input from the outside world, and the memory 102 stores instructions. When the instructions are executed by at least one processor 101, the steps of the method described in the method embodiment are implemented, and the running results are displayed on the display device 104, and the steps of the method described in the method embodiment are implemented.

[0066] In summary, the present invention provides an intelligent parking lot information display system that can update the parking lot information layer in real time according to the user's zoom operation on the third-party map. The system realizes the presentation and management of parking lot information through the Amap API, ensuring that users get the best visual experience and information display at different zoom levels.
