Embodiment
The problem of being existed based on prior art, inventor considers to keep away to try one's best by adjusting the display location of interest point name
The title for exempting from close point of interest is overlapping, therefore, and the display methods of the interest point name of technical solution of the present invention includes：According to
The current display position of one interest point name and the second interest point name determines first interest point name and/or the second interest
The display location of point title, wherein, the second point of interest is at least one point of interest around the first point of interest in map.
Fig. 1 is the schematic flow sheet of the display methods of the interest point name of the embodiment of the present invention, and each step is carried out below
Describe in detail.
Step S1, obtains the current display position of the first interest point name.In map making, it is necessary to first be read from caching
Interest point data is taken, point of interest is placed on to the relevant position in the map to be shown.Because the point of interest in map is numerous,
Therefore an interest point data is read every time, first point of interest refers to the point of interest currently read, reading first
After interest point data, in interest point data expression point of interest icon and its display location data, interest point name and
Its display location data, first point of interest is drawn in map, generally, the positional representation interest where the icon of point of interest
The position of point, the title of point of interest is labeled in the position of the icon close to point of interest.Afterwards after each reading interest point data,
Following step is performed successively.
It should be noted that in step sl, when first interest point name is long, then the interest can be called the roll
Title splits at least two rows, and other points of interest or road name can be covered to avoid interest point name from being placed in map as far as possible
Deng.Generally, the interest point name can be split when the character length of the first interest point name is more than preset characters length
Into at least two rows.For example, preset characters length is 6, if the first interest point name includes 10 characters, 2 can be split into
OK, if the first interest point name includes 15 characters, 3 rows can be split into.
Then step S2 is performed, the current of the current display position of the first interest point name and the second interest point name is judged
Whether display location is overlapping, if then performing step S3, if otherwise performing step S6.Wherein, the second point of interest is the first interest
At least one point of interest around point.
, it is necessary to first judge that the first point of interest (point of interest currently read) title is current after the first interest point data is read
Whether the position of interest point name of the position to be placed (current display location) with having been placed in map can be overlapping, generally
It is to judge the current display position of the first interest point name and (adjacent or close) interest point name, i.e., second around it
Whether the current display position of interest point name is overlapping, and the second interest point name is probably one, it is also possible to multiple.
Collision Detection can be utilized by judging whether the display location of point of interest is overlapping：Judge the first interest point name
Position of the boundary rectangle of position of the boundary rectangle in the map and the second interest point name in the map whether phase
Hand over.When it is implemented, the display location data of interest point name can be coordinate data of the interest point name in map, according to
The character length of coordinate data and interest point name can calculate the position and four summits of the boundary rectangle of interest point name
Coordinate, it is possible thereby to judge whether two boundary rectangles can intersect.For example, as shown in Figure 2 the first point of interest A
The boundary rectangle 21 of interest point name intersects with the boundary rectangle 22 of the second point of interest B interest point name, the first point of interest A's
The boundary rectangle 21 of interest point name and the boundary rectangle 23 of the second point of interest C interest point name are non-intersect.If in addition,
Interest point name is split into at least two rows in step S1, then the boundary rectangle of interest point name includes at least two line characters.Institute
State the minimum rectangle that boundary rectangle typically refers to the alphabet comprising interest point name.
If the boundary rectangle of the boundary rectangle of the first interest point name and one or more interest point names around it
It is intersecting, if illustrating to place the first interest point name meeting interest point name of covering part second according to current display position, need
The display location of overlapping interest point name is adjusted, such as the display location of the first interest point name of adjustment or the second interest are called the roll
The display location of title, or adjust the display location of the first interest point name and the second interest point name.In the present embodiment, first adjust
The display location of whole first interest point name, that is, perform step S3.If the boundary rectangle of the first interest point name and its around
All interest point names boundary rectangle it is non-intersect, then need not adjust the display location of interest point name, it is emerging by first
The current display position of interest point title is defined as the display location of the first interest point name, that is, performs step S6, record first is emerging
The display location of interest point title.
Step S3, adjusts the display location of the first interest point name, until the display of the first interest point name after adjustment
Position display location not overlapping or the first interest point name with the current display position of the second interest point name is before adjustment
It is overlapping with the current display position of the second interest point name afterwards, continue executing with step S4.When first interest point name
Current display position is overlapping with the current display position of second interest point name, then first adjusts first interest point name
Display location, wherein, the display location of the interest point name is located at top, lower section, left or the right of the point of interest.
Interest point name is disposed close to the position of the icon of point of interest, can be icon top, lower section, the left side of point of interest
Side or right, the initial display position of interest point name are general true according to the display location data being stored in map data base
It is fixed, adjust the display location of the first interest point name, until the display location of the first interest point name after adjustment with it is all
The current display position of second interest point name is not overlapping, then performs step S4.For example, the first point of interest A shown in Fig. 2
Interest point name initial display position be the first point of interest A right, due to the interest point name weight with the second point of interest B
It is folded, it therefore, it can adjust the right of the first point of interest A shown in the first point of interest A interest point name from Fig. 2 to such as Fig. 3
The lower section of the first shown point of interest A.In addition it is also possible to adjust to the first point of interest A left；And if adjust to first emerging
Interesting point A top then can be overlapping with the second point of interest C interest point name.
However, the region that point of interest is concentrated in map, then it is possible that the display position of the first interest point name of adjustment
Put to optional position all can be overlapping with the current display position of one or more interest point names situation, for example, such as Fig. 4 institutes
Show, the first point of interest A interest point name understands the second point of interest of covering part B interest point name if displayed on right, such as
Fruit is shown in top meeting the second point of interest of covering part C interest point name, emerging if displayed on left meeting covering part second
Interesting point D interest point name, the second point of interest of covering part E interest point name is understood if displayed on lower section, in the case
Continue executing with step S4.
Step S4, judges that the display location of the first interest point name is rear current aobvious with the second interest point name before adjustment
Show whether position is overlapping, if then performing step S5, if otherwise performing step S6.For example, for the reality shown in Fig. 4
Example, then continue executing with S5；For the example shown in Fig. 3, then step S6 is continued executing with.
Step S5, adjusts the display location of the second interest point name, until the display of the second interest point name after adjustment
Position is not overlapping with the display location of the first interest point name, records display location and the first point of interest of the second interest point name
The display location of title.If the rear display with the second interest point name before adjustment of the display location of the first interest point name
Put overlapping, then the display location of each the second interest point name is sequentially adjusted in based on certain selection principle, its Adjustment principle
Identical with the Adjustment principle of the first point of interest, i.e., the interest point name of the second point of interest is not weighed with the interest point name around it
It is folded.
When it is implemented, by the reading order of the second point of interest the second interest point name can be selected to carry out display location
Adjustment.For example, example as shown in Figure 4, the second point of interest reads and placed according to E, C, B, D sequencing, therefore can be with
The display location of the second point of interest E interest point name is first adjusted, if mentioned above principle can not be met, then second is sequentially adjusted in
Interest point name C, B, D, if can by the position adjustment of the second point of interest E interest point name to other interest point names
Nonoverlapping position, then adjust the first point of interest A interest point name to the first point of interest A lower section, as shown in Figure 5.
The interest of the second point of interest E behind the display location of the interest point name of the first point of interest A after record adjustment and adjustment is called the roll
The display location of title.
Second interest point name overlapping with the initial display position of the first interest point name can also be first selected to be shown
Show the adjustment of position.For example, the example shown in Fig. 4, first adjusts the display location of the second point of interest B interest point name, so
If disclosure satisfy that above-mentioned Adjustment principle, the first point of interest A display location can not be adjusted, otherwise adjust again other second
The display location of interest point name and the display location of the first interest point name.
The second interest point name that can also first select the interest point name of surrounding minimum carries out the adjustment of display location, such as
Fruit disclosure satisfy that above-mentioned Adjustment principle, correspondingly adjust the display location of the first interest point name；Otherwise adjust again other second
The display location of interest point name and the display location of the first interest point name.
It should be noted that in the present embodiment, when first interest point name display location before adjustment after and institute
The current display position for stating the second interest point name is overlapping, then continues to adjust the display location of the second interest point name, that is, hold
Row step S5.And in other embodiments, the display location of the second interest point name can not also be adjusted, but adjustment first is emerging
The display location of interest point title to the minimum position in the current display position overlapping region with second interest point name, example
Such as, as shown in Figure 6.Wherein, overlapping region minimum refers to two boundary rectangles, the i.e. boundary rectangle of the first interest point name and
The intersecting area of the boundary rectangle of two interest point names is minimum.
In addition, performing after above-mentioned steps S5, if the second all interest point name of adjustment can not all meet above-mentioned adjustment
Principle, the then display location that can also adjust the first interest point name is extremely overlapping with the display location of second interest point name
The minimum position in region, or can also abandon showing a point of interest in the first point of interest and the second point of interest.
Step S6, records the display location of the first interest point name.If the initial display position of the first interest point name
(step S2 judged result is no) not overlapping with the display location of the second interest point name, then by the first of the first interest point name
Beginning display location as the first interest point name display location record.If the display position of the first interest point name after adjustment
(step S4 judged result is no) not overlapping with the display location of the second interest point name is put, then by the first interest after adjustment
The display location of point title is recorded as the display location of the first interest point name.
The display location of the interest point name determined by above-mentioned steps becomes the current display position of the interest point name
Put.Repeat the above steps, until the display location of all interest point names will be it has been determined that will finally draw in the map to be shown
Good map denotation on screen, wherein, the display location of each interest point name in map is determined by the above method, upper
If the display location for stating the first interest point name in step is recorded, the first point of interest is likely to become the point of interest of subsequent read
The point of interest of surrounding, that is, the second point of interest.
It should be noted that the display location and the display position of the second interest point name of the above-mentioned interest point name of record first
Put can be the first interest point name that will be determined after adjustment display location data and the display location of the second interest point name
Data deposit caching.Then in drafting and show map, interest point name and its display location data are read from the caching,
