Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making all other embodiment that obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
For the advantage that makes technical scheme of the present invention is clearer, the present invention is elaborated below in conjunction with accompanying drawing and embodiment.
Embodiment 1
The embodiment of the invention provides a kind of map data updating method, and is as shown in Figure 1, and this method comprises:
The map data updating method that the embodiment of the invention provides can compare new and old map, obtains the difference part between new and old map, and filters out the reference by location data of said difference part, to said reference by location data map is upgraded afterwards.Compared with prior art, the reference by location data of the difference part of the embodiment of the invention between can the new and old map of fast updating improve the efficient of map data update.
Embodiment 2
The embodiment of the invention provides a kind of map data updating method, and is as shown in Figure 2, and this method comprises:
Wherein, new and old map is compared, the concrete mode that obtains the difference part between new and old map is:
With the road attribute is reference, and new and old map is compared analysis, and wherein, said road attribute comprises at least one in link name, road shape, crossing link condition, the crossing traffic lights.For example:
As shown in Figure 3, ground A section road is divided into B and two sections roads of C in the legacy version map in the redaction map.New and old map is compared the back find that road attribute such as road shape of the same area and crossing link condition there are differences on the map between new and old map, zone then shown in Figure 3 is the difference part.
Wherein, the concrete mode that filters out the reference by location data of said difference part is:
Utilize the mode of buffer zone analysis to filter out said difference reference by location data partly.For example:
As shown in Figure 3, in the legacy version map, said difference part only needs fragment position reference to represent road A, and in the redaction map, said difference partly needs two fragment position with reference to representing respectively B and C.Utilize the mode of buffer zone analysis to filter out the reference by location data of new and old edition map in said difference part.
Wherein, the server of storage place diagram data only needs to get final product upgrading through the reference by location after the screening according to said reference by location data.Because what upgrade is through the reference by location after the screening, but not complete map, thus the data volume that relates in the renewal process all reduced with the time that is consumed, thereby improved update efficiency.
Wherein, What the server of said storage place diagram data was issued is through the reference by location data after the screening; But not complete map datum so need the time decreased of data quantity transmitted and consumption in the issuing process, has improved the efficient of the reference by location data after issue is upgraded.
Terminal device only needs to get final product according to the map datum in the reference by location Data Update terminal device that receives, and need not upgrade complete map datum, thereby improve the update efficiency of map datum in the terminal device.
The map data updating method that the embodiment of the invention provides; Can compare new and old map; Obtain the difference part between new and old map; And filter out said difference reference by location data partly, to said reference by location data map is upgraded afterwards, and the reference by location data issuing after will upgrading is given terminal device.Compared with prior art, the reference by location data of the difference part of the embodiment of the invention between can the new and old map of fast updating improve the efficient of map data update.
