Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment are only not used in and limit the scope of the invention for the present invention is described.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after having read the content of the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
The first embodiment of the present invention relates to a kind of point of interest planing method, comprises the following steps: acquisition time information and mileage information; Automatically choose point of interest according to the temporal information of obtaining; In the point of interest of choosing, cook up the mileage number route roughly equal with the mileage information of obtaining.As shown in Figure 1, concrete steps are as follows:
Step 101, acquisition time information and mileage information, that is to say, in the time that user need to carry out point of interest planning, by input equipment information input time and mileage information, makes navigation terminal can obtain temporal information and the mileage information of user's input.
Then, enter step 102, automatically choose point of interest according to the temporal information of obtaining, specifically, after time of receipt (T of R) information and mileage information, navigation terminal can be centered by current location, search geographic coverage according to the temporal information of obtaining, and choose point of interest in described geographic coverage.
Finally, enter step 103, in the point of interest of choosing, cook up the mileage number route roughly equal with the mileage information of obtaining.In present embodiment, can adopt fixed length algorithmic rule to go out the mileage number route roughly equal with the mileage information of obtaining, as shown in Figure 2, concrete steps are as follows:
Then, enter step 202, in remaining point of interest, select arbitrarily a point of interest as next point of interest.That is to say, in the situation that getting rid of the first point of interest, select arbitrarily a point of interest as second point of interest.
Then, enter step 203, the guidance path of above-mentioned point of interest return to origin is passed through in planning successively from starting point, that is to say, set out to first point of interest, then through second point of interest, last return to origin is planned a bar navigation path with starting point.
Afterwards, enter step 204, judge that whether the mileage of this guidance path is roughly equal with mileage information, if the mileage of this guidance path and mileage information are roughly equal, enter step 205, otherwise return to step 202.That is to say, roughly equal with the mileage information getting when the distance of the guidance path of planning, enter step 205, otherwise return to step 202.
Finally, enter step 205, show the guidance path of having planned.
For example, when user need to carry out point of interest planning, by input equipment information input time and mileage information, wherein, temporal information is 1, mileage information is 50 kilometers, navigation terminal gets after temporal information and mileage information, obtain current location on " in South Road, Tibet Shan Nan mono-tunnel " by GPS locating module, then, centered by " in South Road, Tibet Shan Nan mono-tunnel ", search geographic coverage according to the temporal information of obtaining " 1 day ", and choose point of interest in described geographic coverage, the point of interest of choosing is " outbeach ", " Town God's Temple ", " Oriental Pearl ", " Nanjing Road Walk Way ".Then, using " in South Road, Tibet Shan Nan mono-tunnel " as starting point, from the point of interest of choosing, a point of interest of random selection is as the first point of interest, for example " outbeach ", from remaining point of interest " Town God's Temple ", " Oriental Pearl ", " Nanjing Road Walk Way ", select at random again a point of interest for example, as next point of interest, Oriental Pearl.After completing, planning is from the guidance path of " South Road, Tibet Shan Nan mono-tunnel "-" outbeach "-" Oriental Pearl ", if the mileage information of this bar navigation path and input " 50 kilometers " is roughly equal, will show this guidance path by the display screen of navigation terminal.Wherein roughly equally can determine by difference is between the two set, for example both differences are roughly equal for representing in 2 kilometers.If difference is larger, again from remaining point of interest random select a point of interest for example Town God's Temple as next point of interest (be Oriental Pearl after point of interest).It is worth mentioning that, because the point of interest of choosing is before chosen according to temporal information, therefore occur that guidance path is greater than the possibility of mileage information very little, if there is the next point of interest using the point of interest of newly selecting as the first point of interest, the next point of interest by Town God's Temple as outbeach.Afterwards, plan again from the guidance path of " South Road, Tibet Shan Nan mono-tunnel "-" outbeach "-" Oriental Pearl "-" Town God's Temple ", judge by the way that more whether the mileage obtaining is roughly equal with the mileage information of input, if equated, show this guidance path, unequal continuation returns.
Be not difficult to find, the present invention can choose point of interest automatically according to time and the mileage of user input, and cooks up the multiple points of interest of process and meet the route of user's request, thereby has facilitated user.
The second embodiment of the present invention relates to a kind of point of interest device for planning, as shown in Figure 3, comprising: time-obtaining module 301, for acquisition time information; Mileage acquisition module 302, for obtaining mileage information; Choose module 303, automatically choose point of interest for the temporal information of obtaining according to time-obtaining module 301; Route planning module 304, for cooking up the roughly equal route of mileage information that a mileage number and mileage acquisition module 302 obtain choosing point of interest that module 303 chooses.Wherein, described in choose module 303 centered by current location, the temporal information of obtaining according to time-obtaining module 301 is searched geographic coverage, in described geographic coverage, chooses point of interest.
Described route planning module adopts fixed length algorithmic rule to go out the mileage number route roughly equal with the mileage information of obtaining.As shown in Figure 4, described route planning module comprises: starting point is set submodule 401, is starting point for setting current location; The first point of interest is set submodule 402, for choosing arbitrarily a point of interest and be set as the first point of interest from choosing module; Next point of interest is set submodule 403, for selecting arbitrarily a point of interest to be set as next point of interest choosing in the remaining point of interest of module; Planning submodule 404, for planning the guidance path that passes through successively above-mentioned point of interest return to origin from starting point; Judge submodule 405, roughly equal for judging the no mileage information of obtaining with mileage acquisition module of the guidance path planned of planning submodule 404, if roughly equal, show the route through above-mentioned point of interest by display module, set next point of interest otherwise set submodule 403 by next point of interest.
As can be seen here, the present invention can choose point of interest automatically according to time and the mileage of user input, and cooks up the multiple points of interest of process and meet the route of user's request, thereby has facilitated user.
