Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 is a flowchart illustrating a parking lot map data generation method according to an embodiment of the present invention, and as shown in fig. 1, the method includes:
step S110, determining one or more target parking lots to be generated with map data; the map data includes contour surface data and/or entrance and exit data.
For example, if map data needs to be generated for parking lots in a lake area, the target parking lot is all parking lots in the lake area.
Step S120, for each target parking lot, identifying the contour surface of the target parking lot in a live-action 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 live-action map, marking each entrance and exit, and adding one or more entrance and exit attributes to each entrance and exit to obtain entrance and exit data of the parking lot.
In this embodiment, the contour surface and the entrance/exit of the target parking lot may be identified by using a corresponding identification algorithm. The live-action map is different from a common map, and is usually three-dimensional, so that the details of the building can be accurately identified.
In step S130, the obtained map data of each target parking lot is exported to a file in a specified format.
It can be seen that, the method shown in fig. 1, which uses the real-scene map as a basis to generate map data including contour surface data and/or entrance and exit data for the determined target parking lot, may be specifically implemented by identifying and marking the contour surface and/or the entrance and exit in the real-scene map, and adding a parking lot attribute or an entrance and exit attribute thereto. After the parking lot map data are obtained, the parking lot map data can be exported to a file with a specified format, so that the parking lot map data can be conveniently further checked or used in a specific scene. According to the technical scheme, the real-scene map is used for generating the map data of the parking lot, the labor cost of on-site collection is saved, the data format is preliminarily standardized through the file with the specified format, and the map data can be conveniently and effectively processed and utilized in the later period.
In an embodiment of the present invention, the method, wherein determining one or more target parking lots to be generated with map data includes: 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 includes one or more of the following: the method comprises the following steps of (1) identifying a parking lot, short for the parking lot, full name of the parking lot, longitude and latitude of the parking lot and information of an entrance and an exit of the parking lot; the method further comprises the following steps: and importing the basic information of the parking lot into the live-action map, and converting the basic information into map data of the corresponding parking lot.
With the development of technology in the field of intelligent parking lots, many providers of intelligent parking lot management services collect basic information of many parking lots, such as names of the parking lots, and the like. In the embodiment, the existing information is reasonably utilized, and the basic parking lot information is stored in the parking lot database as an example, the information in the database is imported into the live-action map and converted into the map data of the corresponding parking lot, so that format synchronization can be completed. Since this information is usually accurate, in one embodiment of the invention, the method further comprises: the map data of the parking lot converted from the basic information of the parking lot is set to a protection state in which deletion is prohibited.
In this way, the map data added after the outline is recognized can be edited and modified; and the map data directly converted from the basic information of the parking lot is protected, and the stability and consistency of the data are maintained. It should be particularly noted that the basic information may not include the longitude and latitude of the parking lot, but includes coordinate information in the third-party electronic map such as the hundred-degree latitude, which may not be unified with the standard longitude and latitude used by the live-action map, and then the hundred-degree latitude needs to be converted into the standard longitude and latitude.
In one embodiment of the present invention, in the method described above. The step of identifying the profile of the target parking lot in the live-action map comprises the following steps: identifying the profile surface of the target parking lot in a real scene map according to the basic information of the target parking lot and/or the input positioning instruction; identifying one or more entrances and exits of the target parking lot in the live-action map includes: and identifying one or more entrances and exits of the target parking lot in the live-action map according to the basic information of the target parking lot and/or the input positioning instruction.
If the basic information of the parking lot is perfect, the basic information can be directly converted into available map data; if the basic information of the parking lot is not perfect enough, the basic information needs to be supplemented, and how to identify the contour surface and the entrance and exit of the target parking lot is shown in the embodiment. For example, the basic information of the parking lot includes the longitude and latitude of the parking lot, so that the positioning can be directly performed in the live-action map, and if the basic information of the parking lot does not include the longitude and latitude of the parking lot, an externally input positioning instruction needs to be received for positioning. The two can also be combined to improve the accuracy of the positioning.
In an embodiment of the present invention, in the method, the live-action map is an earth scene in google earth software; marking the contour surface and adding one or more parking lot attributes to the contour surface includes: calling a polygon editing function of Google earth software, marking a profile surface of the target parking lot by a polygon containing a plurality of drawing points in an earth scene, and adding one or more parking lot attributes of the target parking lot in the attributes of the polygon; marking each access and adding one or more access attributes for each access respectively comprises: and calling a landmark editing function of Google Earth software, marking one or more entrances and exits of the target parking lot by using independent landmarks in the earth scene, and adding one or more entrance and exit attributes of the entrance and exit in the attributes of each landmark.
The Earth scene formed by satellite imagery provided by Google Earth (Google Earth) can be utilized by us exactly. We can also call some functions of the software directly to implement some steps in our method, for example: and calling an editing polygon function in Google earth software, and marking the contour surface of the target parking lot by using a polygon containing a plurality of drawing points in an earth scene, wherein the drawing points are preferably 3-50, and the boundary of the parking lot is drawn. The plotted points may be edited, including moved positions or deleted. It should be noted that if the parking lot is an underground parking lot, the outline of its corresponding above-ground building should be depicted. And the entrance is used as a landmark, and the landmark editing function in Google earth software can be utilized to mark in the earth scene. Furthermore, the attribute editing of the landmark and the polygon may be used to edit the parking lot attribute and the entrance/exit attribute. It should be noted here that the doorway is located on the boundary of the parking lot and on the boundary of the road.
Specifically, in an embodiment of the present invention, the above method, wherein adding one or more parking lot attributes to the contour surface includes: determining the name of the polygon and the description information of the polygon according to the basic information of the parking lot and/or determining the name of the polygon and the description information of the polygon according to the input profile description information; the description information of the polygon includes one or more of the following: parking area type, parking lot address, parking lot charging standard and parking lot opening time; adding one or more gateway attributes to each gateway respectively comprises: determining the name of each landmark and the description information of the landmark according to the basic information of the parking lot, and/or determining the name of the landmark and the description information of the landmark according to the input entrance description information; the descriptive information of the landmark includes one or more of the following: the access address, the access type, the access open state and the access exemption information.
For example, the name of the polygon should be a name of a parking lot, and can be further detailed as a full name of the parking lot, a short name of the parking lot, or an alternative name of the parking lot according to requirements. Fig. 2 shows an exemplary diagram of marking out a profile of a certain parking lot using an edit polygon function in google earth software. (to combine with actual requirements, a real parking name is randomly selected, which is only an example). As shown in fig. 2, the name of the polygon is named "tianya guqigong city parking lot". The following blank area may add description information to the polygon, that is, other parking lot attributes, which may be selected according to the requirement, and when there are multiple parking lot attributes, comma separation is required. The sequence of the parking lot attributes can be determined according to preset rules. Examples of some parking lot attributes are as follows: the parking lot is an underground parking lot, and 'underground' is written in the description information; the parking area is outdoors, "outdoors" is written in the specification information, and the like. "south" and "northeast" in fig. 2 are implemented by the editing landmark function, and fig. 3 shows an exemplary diagram of marking an entrance of a certain parking lot in google earth software using the editing landmark function. (again, random selection is by way of example only). As shown in fig. 3, the name of the landmark is named "beijing hospital parking lot northwest", wherein the name of the parking lot should be the same as the name of the polygon corresponding to the contour surface of the parking lot. In other embodiments, the landmark name may be set according to requirements, for example, "parking lot is abbreviated as + '_' + entrance/exit official name + position", if the entrance/exit official name is not available, the position is not filled, the position is which direction of the center position of the parking lot the entrance/exit is located, and if there are multiple exits in the same position, the exit direction is increased to avoid the same name. In the description information section, "entrance" in fig. 3 indicates that the entrance is both an exit and an entrance (many car park exits and entrances are separated), "open" indicates that the entrance is currently open (may also be "not open" or "open to the inside"), and in other embodiments, there may be an entrance with a fixed opening time, and it is also necessary to record the opening time in a specific time format, for example, "open (09:00-18:00,20:00-24: 00)" in which the requirement symbol is a half-angle symbol and the time must be XX: XX. The first "yes" indicates that the doorway may pay a parking fee using the premium service, and the second "yes" indicates that the doorway is a main doorway (many parking lots also have a plurality of parking areas, and the doorway between the parking areas cannot directly exit the parking lot, and thus is not a main doorway). It can be seen that the plurality of entrance and exit attributes can also be determined according to a preset rule.
In the earth scene of the real scene map in the google earth software, the method comprises the following steps of exporting the map data of each target parking lot into a file with a specified format: respectively establishing folders for each target parking lot in Google Earth software, and storing the map data of each target parking lot in the corresponding folders; and calling a position storage function of Google earth software, and exporting the map data of each target parking lot stored in each folder into a file in a kml format.
Since the map data of one parking lot is various, in this embodiment, folders may be first established for each target parking lot in google earth software, and then the map data of the target parking lot may be stored in each folder. Therefore, when data are exported, only the data of the whole folder need to be exported, and the method can be realized by directly calling the position storage function of the Google Earth. The kml (Keyhole MarkupLanguage) format may hold data for different attributes by field.
The obtained data can be manually checked and then used as available data to be stored in a database, and when constraint rules are set for each field, the data can be processed in a batch processing mode. In an embodiment of the present invention, the method further includes: when the exported files in the kml format have multiple copies, combining the multiple copies of the files in the kml format into a summary file in the kml format; exporting profile data to a profile sorting Excel table according to fields from a exported file in a kml format/a merged summarized file in a kml format, and/or exporting entrance data to an entrance sorting Excel table according to fields; arranging Excel tables of the contour surface according to field attributes and processing according to preset field standardization rules, and/or arranging Excel tables of the entrance and exit according to field attributes and processing according to preset field standardization rules; and importing the profile surface arrangement Excel sheet or the entrance and exit arrangement Excel sheet after the normalization processing into the parking lot map database, or merging the profile surface arrangement Excel sheet and the entrance and exit arrangement Excel sheet after the normalization processing and importing into the parking lot map database.
That is, the map data of the target parking lot generated in the above embodiment may be executed on one machine or may be executed on a plurality of machines; one or more copies of the file in the kml format thus exported may be possible, and we may merge the multiple copies of the file to obtain one summary file (if only one copy of the file in the kml format is exported, it is already the summary file). At this time, data needs to be checked and sorted, and standardized processing can be performed according to field attributes by using preset rules. For example, a regular expression is used to find whether there is time information which does not meet the specification (for example, a half-angle symbol is input as a full-angle symbol), or longitude and latitude coordinates are converted into hundred-degree coordinates, so that a third-party map can be accessed for use, and the like. The contour surface arrangement Excel table and the entrance and exit arrangement Excel table can be Excel data tables in formats such as xls, xlsb, xlsx and the like, can be empty tables, and can also be data tables of basic information led into the parking lot, so that newly-added parking lot map data (obtained by directly converting the basic information of the parking lot) can be displayed in different formats.
Corresponding to the parking lot map data generation method, the invention also provides a parking lot map data generation device. Fig. 4 shows a schematic structural diagram of a parking lot map data generation device according to an embodiment of the present invention, and as shown in fig. 4, the parking lot map data generation device 400 includes a processor 410 and a machine-readable storage medium 420, where the machine-readable storage medium 420 stores machine-executable instructions capable of being executed by the processor 410, and the processor 410 is caused by the machine-executable instructions to implement the steps of the parking lot map data generation method in any one of the embodiments described above.
Additionally, an embodiment of the present invention further provides a machine-readable storage medium storing machine-executable instructions that, when invoked and executed by a processor, cause the processor to: the steps of the parking lot map data generation method in any of the above embodiments are implemented.
In summary, in the technical solution of the present invention, a real-scene map is used as a basis to generate map data including contour surface data and/or entrance and exit data for a determined target parking lot, and specifically, the contour surface and/or the entrance and exit may be identified and marked in the real-scene map, and a parking lot attribute or an entrance and exit attribute is added to the real-scene map. After the parking lot map data are obtained, the parking lot map data can be exported to a file with a specified format, so that the parking lot map data can be conveniently further checked or used in a specific scene. According to the technical scheme, the real-scene map is used for generating the map data of the parking lot, the labor cost of on-site collection is saved, the data format is preliminarily standardized through the file with the specified format, and the map data can be conveniently and effectively processed and utilized in the later period.
