Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
The invention provides a method and a device for updating navigation electronic map data, aiming at the problems of long updating period, poor data freshness and the like of the navigation electronic map data in the prior art.
As shown in fig. 2, the present invention provides a method for updating navigation electronic map data, including:
step 10, obtaining updated data different from the original data;
step 20, constructing the updated data into a homonymous derivative table with the same table structure as the original data table, wherein the original data table is in an intermediate data format;
and step 30, compiling a final data format according to the original data table of the intermediate data format and the homonymy derivative table.
In the embodiment of the invention, the data is quickly updated mainly aiming at the attribute data, the updating content of the attribute data of the navigation electronic map is relatively clear, the subsequent product verification test object is clear, and the quality control degree is higher. The intermediate data format used for compiling the navigation electronic map data may include data formats such as MIF/MID or SQLITE, and the intermediate data format is divided into two parts of space data and attribute data no matter what data format is used. The attribute data is generally composed of a plurality of data tables, and one data table or a plurality of data tables describe a navigation electronic map element to ensure certain integrity in logic.
For a specific navigation electronic map element, the change of the attribute data may include (1) information addition; (2) deleting the information; (3) information update, wherein "information update" can be understood as two processes acting in succession: deleting the old information and adding the new information. That is, all attribute data changes can be divided into two processes: and deleting the old information and adding the new information. The homonymous derivation table constructed in step 20 in the embodiment of the present invention is used to implement the old information deletion and new information addition processes of the navigation electronic map attribute data. This process can be applied to data updates of key elements or attributes and fast corresponding modifications of customer key relationship issues. As shown in fig. 3, in step 30, the homonymous derivative tables and the original data tables in the intermediate data format are used together to perform data compilation, and finally, a final data format is formed. The table structure (field name, field content and field type) of the derived table is consistent with the original data table, no change is needed, even if the field which is not utilized needs to be reserved (information is kept unchanged), the content in the corresponding field only needs to be updated; and in the compiling process, similar compiling codes are developed for related tables in the original intermediate data format, so that the cost for the compiler to develop the same-name derivative table with the same table structure is low, namely the logic of the updated content of the attribute data of the navigation electronic map is clear, the attribute table structure does not need to be redesigned, and the development cost of the compiler is greatly saved.
It should be noted that, for a navigation electronic map element described by one data table or multiple data tables, there is slight difference in the content of the homonymous derivative tables that construct the same table structure, the basic principle of the navigation electronic map data updating method of the present invention must be directed to the complete logical structure of the navigation electronic map element, that is, if an element is composed of a single data table, and when performing fast update, the homonymous derivative tables that construct the homonymous structure of the single data table are updated as a whole; if one element is composed of a plurality of data tables, when a quick update is performed, it is necessary to construct a homonymous derivative table having the same table structure of the plurality of data tables and perform the entire update. The same name derivative table of the same table structure is constructed as a complete structure.
In one embodiment of the invention:
suppose the name of the information adding table is ADD and the name of the information deleting table is DELETE.
In certain navigation electronic map data, a certain road in a certain place is greatly widened, the traffic transport capacity is improved, fields such as the type, the road width, the number of lanes and the like in basic attribute elements of the road need to be modified, and the path planning calculation process of a navigator is optimized. The basic attribute elements of the ROAD are only composed of a ROAD _ LINK single table, so that the same-name derivative tables with the same table structure are constructed to quickly modify the ROAD type, the ROAD width and the number of lanes, and the basic attribute elements are two tables of ROAD _ LINK _ DELETE and ROAD _ LINK _ ADD, and have the same structure as the ROAD _ LINK table.
In another embodiment of the invention:
suppose the name of the information adding table is ADD and the name of the information deleting table is DELETE.
In certain navigation electronic map data, a certain exit on a certain important loop road is communicated with other important roads, so that customers pay attention to the freshness of the data and need to update the name of the exit in related attributes of the roads. The exit NAME element consists of two tables, namely ROAD _ SIGN _ NAME and ROAD _ SIGN _ TRANS, so that the same NAME derivative tables with the same table structure are constructed to quickly modify the exit NAME, and four tables, namely ROAD _ SIGN _ NAME _ DELETE, ROAD _ SIGN _ TRANS _ DELETE, ROAD _ SIGN _ NAME _ ADD and ROAD _ SIGN _ TRANS _ ADD, are required to be included, and the table structures are respectively the same as ROAD _ SIGN _ NAME and ROAD _ SIGN _ TRANS.
In the above embodiment of the present invention, step 10 specifically includes:
step 101, collecting real-time data, and comparing the real-time data with original data;
and 102, acquiring real-time data different from the original data, and determining the real-time data as updated data.
In the embodiment of the present invention, the real-time data collected in step 101 may be collected on-site, or may be collected through real-time update of a network, or may be collected and updated by a certain update time node or according to a requirement, which is not limited to a certain fixed form, and all the ways of correctly collecting update data are applicable in the present invention. Comparing the real-time data with original data of a navigation electronic map, determining whether newly added real-time data and real-time data different from the original data exist, and if not, namely the real-time data is completely the same as the original data, not executing any operation; and if the real-time data different from the original data exists, acquiring the real-time data different from the original data, and determining the real-time data as the updating data.
In the above embodiment of the present invention, step 20 specifically includes:
step 201, constructing an information newly-added table with the same structure as an attribute data table of the original data, wherein the information newly-added table comprises different and newly-added updated data compared with the original data;
step 202, constructing an information deletion table with the same structure as the attribute data table of the original data, wherein the information deletion table comprises the original data which is different and redundant compared with the updated data.
In the embodiment of the invention, the homonymy derivation table comprises an information adding table and an information deleting table; the information addition table includes different and newly added update data compared with the original data, and the information deletion table includes different and redundant original data compared with the update data. Further, according to the actual situation, when the updated data only has information addition relative to the original data, the information deletion table is empty; and when the updated data only has information deletion relative to the original data, the information newly added table is empty.
In yet another embodiment of the invention:
suppose the name of the information adding table is ADD and the name of the information deleting table is DELETE.
In certain navigation electronic map data, a certain road in a certain place is greatly widened, the traffic transport capacity is improved, fields such as the type, the road width, the number of lanes and the like in basic attribute elements of the road need to be modified, and the path planning calculation process of a navigator is optimized. The basic attribute elements of the ROAD are only composed of a ROAD _ LINK single table, so that the same-name derivative tables with the same table structure are constructed to quickly modify the ROAD types, the ROAD widths and the lane number sections, and the basic attribute elements are two tables of ROAD _ LINK _ DELETE and ROAD _ LINK _ ADD, and have the same structure as the ROAD _ LINK table.
Suppose that the original road type is 4 (a specific road type), the road width is 7m, and the number of lanes is 3 lanes; after the road expansion, the road type is 3 (a specific road type with higher grade), the road width is 12m, and the number of lanes is 5; other information refers to the original ROAD _ LINK table.
The original ROAD _ LINK table is as follows:
the table ROAD _ LINK _ DELETE is:
the table ROAD _ LINK _ ADD is:
the following are two specific cases regarding the ROAD _ LINK table, and only one of the deletion or addition types exists:
the changed road just exemplified still can not meet the increasingly huge traffic flows, and only needs to newly add related information when a small section of auxiliary road is additionally arranged beside the changed road for traffic flow transition. The various information actually collected back is shown in the example.
The table ROAD _ LINK _ ADD is:
after the auxiliary road is opened and the main road is operated, the road surface is suddenly seriously collapsed, and the original normally operated main road is quickly influenced. And the related department decides to close the short section of the auxiliary road in emergency and carry out ground backfilling. At this time, only the relevant information needs to be deleted. The specific information is still as shown in the previous case.
As shown in fig. 4, in the above embodiment of the present invention, step 30 specifically includes:
step 301, importing all original data tables with intermediate data formats as they are, and importing the same-name derivative tables at the same time;
step 302, finishing old information deletion and new information insertion of the original data according to the same-name derivative table to obtain a total amount of information;
step 303, compiling the full information to generate a final data format.
In the embodiment of the invention, the final data format is compiled, which is an important process for realizing the navigation electronic map data product. The compiling process is understood to be a process of decomposing and converting the converted intermediate format data into various small files and folders having logical relationships by using a specific compiler. Generally, the compiled generated data is binary navigation electronic map data, and is more suitable for the hardware realization requirements of navigation software or secondary developers.
The compiling process is actually a format conversion process of the navigation electronic map data, and the navigation electronic map data are required to be converted without loss and error. The compiler and the compiling logic are not fixed, and the specific implementation process is related to each navigation electronic map product provider/software manufacturer and the like.
Currently, in the navigation market, the mainstream converted intermediate format data format includes the RDF data format of NAVTEQ, NIMIF data format of my company, GDF data format, etc., and the compiled final data format includes the KIWI format of the japanese family, the SDAL format of NAVTEQ, the NDS format of the european and american family, and other custom, etc. During specific compiling, all the intermediate data format original data tables can be imported in an original mode, old information deletion is realized by using a same-name derivative table-delta, and a logic process of compiling the whole information after new information is inserted and updated is realized by using the delta-ADD table.
In the embodiment of the invention, aiming at the intermediate data format of the result used before final compilation, a homonymy derivative table, namely a table-DELETE and a table-ADD, with the same table structure as the intermediate data format of the result are constructed to implement the idea and process of deleting old information and quickly updating new information added data of the attribute data of the navigation electronic map. This process is applicable to data updates of key elements or attributes and fast corresponding modifications of customer key concerns.
