Embodiment

The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.

Below to utilize digital picture to illustrate the forming process of dynamic travel notes.

Example 1

Such as, how people in tourism process, and utilize and have geographic positioning system, as GPS, the digital equipment of function, as mobile phone etc., carries out shooting and obtain a lot of photos, by the various local conditions and customs in approach place in these photo record tourism processes.How to utilize these photos as follows to the process of the electronic Dynamic travel notes forming this:

See Fig. 1, be depicted as the realization flow figure of dynamic travel notes in this example.

Step 1, the photo first obtained shooting carries out collection and forms corresponding photograph collection.

Because the mobile phone used during shooting has Geographic mapping function, therefore when taking digital photos, geographical location information now and temporal information can be obtained by mobile phone, and be embedded into and captured often open in digital photos, such as: be recorded in and often open in the EXIF part of photo, thus make often to open geographic position and the temporal information that photo all has shooting.

Certainly for geographic position and the temporal information of often opening photo, except obtaining when taking, equally also can be formed by the interpolation in later stage.

Often opening except the inside of photo for the geographic position and temporal information of often opening photo except remembeing, also can separate records.

Step 2, in the photograph collection formed, selects strategy by predetermined, picks out the some photos for formative dynamics travel notes from photograph collection.

When carrying out selecting photo, automatically can be selected according to corresponding strategy by corresponding program or software, or manually being selected according to the needs of oneself by user.

The strategy of selecting followed in election process comprises the upper limit of selecting photo number and specifically selects estimating of photo, such as: the Annual distribution and/or location distribution etc. of photo.Choose for according to Annual distribution, simple similar items on average often selects one in several.

Such as: if 10 will be selected according to time average distribution from 100 photos, so these 100 photos can be sorted according to time order and function, the photo in shooting time evening comes after shooting time photo early, and then every 10 1 group, often group selects the 1st.

Step 3, completing after photo selects, sorts select photo according to predetermined ordering strategy.

Comparison film carries out sort method can be estimated based on some and carry out manually or auto-sequencing.Such as: according to time order and function order, select photo can be sorted.

Step 4, for sorted photo, according to predetermined strategy, according to the geographic position during shooting of adjacent Digital Media, for every two adjacent photos distribute a suitable atlas dimension, to provide applicable display to present meeting under different condition.

Allocative decision concrete in this example is as follows:

4.1, first classify

Assuming that a corresponding the three unities of photo, in order to as far as possible clearly present the path between adjacent 2, avoid the convergent-divergent that map is too much in Dynamic Announce process simultaneously, can limit atlas dimension quantity N, N is at most identical with the yardstick quantity that electronic chart provides.N can determine according to the fixed value of initially specifying, and also dynamically can determine in computation process.

Then N class is divided into all adjacent 2 according to the distance between them.When classifying, if N is the fixed value according to initially specifying, then adopts fixation to classify, being divided into N class by all adjacent 2 according to the range averaging between them; If N is the value dynamically determined, then adopt dynamic method classification, namely with below described determine yardstick time together with calculate, as long as determine an initial value N=1 and upper limit, such as: N can not more than 3.

See Fig. 3, it is depicted as whole journey path schematic diagram.9 photos are had in whole path, and often open the corresponding the three unities of photo, the geographical latitude and longitude coordinates of these 9 points is respectively: A (31.131318,121.401201), B (34.259611,108.947029), C (34.252636,108.95287), D (34.384319,109.283184), E (36.064755,103.816982), F (36.06639,103.774614), G (38.930705,100.457043), H (38.97029,100.024727), I (40.142165,94.661884).See Fig. 4, it is depicted as adjacent 2 distances in 9 points.For these 9 points, fixation is adopted to be divided into 2 classes according to distance by all adjacent 2: the first kind is: AB, DE, FG, HI; Equations of The Second Kind is: BC, CD, EF, GH(are as shown in Figure 5).

4.2, yardstick is determined

After classification, according to specific viewing area, be each class i.e. wherein all adjacent 2 atlas dimension of specifying an applicable viewing area.

First define minimum visual range D, it is the distance (shown in Fig. 6) on a screen display; When being presented on screen, if their physical distances on screen are less than D, then think that be difficult to differentiate at these 2 at 2, concrete manifestation is exactly that the mark of 2 leans on too near thus has overlap (as shown in Figure 7); If be greater than D, then think that can differentiate at these 2, namely the mark of 2 is got and is comparatively opened.

Can be a value in certain scope to the atlas dimension that a certain class is suitable.The upper limit of this scope is: when atlas dimension is large as far as possible, to make in such can be comprised within viewing area at all adjacent 2.

This range lower limit is: if when the upper limit, in such, between all adjacent 2, the minimum value of screen distance is greater than minimum visual range D, so, when atlas dimension is little as far as possible, the screen distance between corresponding adjacent 2 of this minimum value is not less than D; Otherwise, be higher limit.Consider computation burden, can capping under default situations.

For the classification that fixed cluster method obtains, determine complete to this yardstick.

For the classification that dynamic cataloging method obtains, from N=1, for each class, determine its atlas dimension according to described method above.Particularly, for a certain class, if wherein be a little all adjacent between two, such as: N=1, if available, can by such the broken line a little or between all adjacent 2 give the interface of map vendors, directly determine a bounding rectangles that can comprise these points, also just obtain a suitable atlas dimension simultaneously.Then, will under this atlas dimension, spacing be less than adjacent 2 of D and be included into the new class created.Repeat this process, until: the upper limit reaching N, or all adjacent 2 are disposed, or reach the yardstick restriction of electronic chart; Be as the criterion with the condition first arrived.

Thus, when yardstick is determined in the grouping for above-mentioned two classes, for the first kind, the distance between AB wherein 2 is the longest, determines the upper limit (as shown in Figure 8) with this; Distance wherein between HI 2 is the shortest, determines lower limit (as shown in Figure 9) with this.Between the upper and lower bound determined, determine that the atlas dimension of the first kind is three, namely give atlas dimension 3(as shown in Figure 10).

In like manner, determine that the atlas dimension of Equations of The Second Kind is eight, namely give atlas dimension 8(as shown in figure 11).

4.3 determine screen display location

After the atlas dimension giving adjacent 2 appointments applicable viewing area, will determine that each point is current screen position, and guarantee that each point is within viewing area.

Provide a kind of method detailed below, by giving distribute a map denotation border at often pair adjacent 2, thus determine each position of point on screen, detailed process is as follows:

(1) set of all adjacent 2 is P, if S set is empty, gets first to adjacent 2 Pc in P;

(2) S set is put into by 2 of Pc; Under the atlas dimension of Pc, determine the geographic range A that on-screen display (osd) area is corresponding on map, such as: the rectangle that a long x determined is wide;

(3) in P, take off a pair untreated adjacent 2 Pn.If got, forward step (4) to; Otherwise, terminate;

(4) if the atlas dimension of Pn is identical with Pc, form S set t by latter 1 of Pn together with S set, forward step (5) to; Otherwise, forward step (6) to;

(5) determine that whether the region of all Vertex cover in St is more than A: if do not had, replace S with St, forward step (3) to; Otherwise, forward step (6) to;

(6) for determining a little corresponding map denotation border (determining by the absolute latitude and longitude value of frontier point) in S, these points can be included in on-screen display (osd) area, and give all adjacent 2 points involved by S by this map boundary line, and identify these adjacent 2 for processed; Empty S;

If come this from step (4), replace Pc with Pn, forward step (2) to;

If come this from step (5), put into S by 2 of Pn, forward step (3) to.

Below to determine that the indication range of BCDF point in Fig. 3 is to further illustrate such scheme.

See Figure 12, its be the distance relation schematic diagram between BCDF in map 4.Figure 13 is the size of screen.

Thus, when by the screen size determination indication range of such scheme according to Figure 13, BCD 3 can be illustrated in the screen shown in Figure 13, and F point is beyond the scope of screen display, so do not consider when showing, only consider that when showing BCD 3 both can (as shown in figure 14).

After determining display BCD 3, BCD 3 is shown (as shown in figure 15) between two parties.

Step 5, for sorting and distributing the photo of atlas dimension, shows the geographic position of often opening photo successively on electronic chart, and between the geographic position of the adjacent photo of display, show the path (as shown in Figure 3) from any to another point.This path is the true path between 2 that are depicted by electronic chart.

When showing certain point, the atlas dimension of its correspondence is about to the yardstick decision of adjacent 2 of display by the next one.

Under certain atlas dimension, all adjacent 2 that this yardstick can be made corresponding are all positioned within viewing area.Path between the geographic position that adjacent two photos are corresponding can be generated by the geographic position that photo in initial photograph collection is corresponding.

For the path shown between the geographic position of the adjacent photo of display from any to another point, the interface of electronic chart provider can be utilized to generate presenting based on true path.

The path that can show this tourism dynamically based on above-mentioned five steps on corresponding electronic chart and the place arrived, thus form corresponding electronic Dynamic travel notes.

Example 2,

On the basis of this example electronic Dynamic travel notes implementation in example 1, provide a prioritization scheme:

Namely this prioritization scheme when presenting the path between geographic position and successively at adjacent 2 with the form of map, can also show photo corresponding to geographic position simultaneously.

For the display of photo, static mode or dynamic mode can be selected to show:

When with map view display static content, such as: the path of actionless geographic position and adjacent point-to-point transmission, show corresponding photo, as Figure 17 and 19 simultaneously.This is that a static state presents process, can continue one period of long period, such as 3 seconds.

When showing dynamic content with map view, when entering certain geographic position if show on map, see Figure 16 and Figure 18, corresponding geographic position A and B, can show in a dynamic way on map, and the dynamic-form as fallen presents; While geographic position A and B dynamically presents, the photo 1 of its correspondence and 2 dynamically enter above map, and show.

If show by (carrying out switching display between 2) during path between adjacent 2 points (A and B) on map, see Figure 18, after first position (A) has been moved, path between A and B 2 adopts the mode of entrance strengthened gradually from the superficial to the deep to show, second place B presents dynamically simultaneously, like this when path shows, second geographic position also movement simultaneously completes (as shown in figure 19).

While dynamically presenting path, from the previous corresponding photos of adjacent 2 dynamically (such as: be fade-in fade-out) be switched to the photo (photo as switched Figure 18) corresponding to latter.This is one and dynamically presents process, can continue one period of short period, such as: now entering certain geographic position with 0.5 stopwatch, with 0.5 stopwatch now by the path of adjacent point-to-point transmission.Reenter static state after switching and present process, as Figure 17 and Figure 19.

In the process dynamically presented, can also play as required and add audio-frequency information in advance.

For the orientation that photo shows on map, photo and map can occupy the region of same or similar size respectively, and photo can be positioned at visual focus position, such as: photo upper, map under, as the layout presented in Figure 16 to Figure 19.

Example 3,

On the basis of this example electronic Dynamic travel notes implementation in example 1 and example 2, another is provided to strengthen orbit generation method by the mode of artificial input trajectory fast, and with the display in path between this address location realizing adjacent photo on map.

The method in path between the address location showing adjacent photo on map provided in this example, can allow user oneself directly to specify a certain section of path with input equipment by the mode described.

Such as, sometimes the interface that provides of map vendors cannot drawing path between the geographic position of specifying, or do not conform to the actual conditions in the path of drawing, as shown in figure 20,3 tracing points A, B and C are had in its pictorial map, by the interface of map vendors, can drawing path between AB, and cannot draw between BC.The method that can be provided by this example for this situation carrys out specified geographic location, the drafting of realizing route.

Detailed process following (see Fig. 2):

(11) manual path pattern is first entered into.

(12) user uses on the electronic chart of input equipment in viewing area and identifies continuous route.Stretch line can be drawn, also can draw multistage route; Can be straight line, also can be curve.This process as drawing software setting-out, such as: when pointing by time on the touchscreen, starting to draw and recording a new continuous route, along with finger moves on the touchscreen, continuous drafting and record, when finger leaves touch-screen, ends drawing and record current continuous route.

As shown in figure 21, on the map shown in Figure 20, a continuous print route has been drawn between D and E 2 by input equipment based on said method.

Input equipment described here comprises all equipment that input signal can be converted into continuous print line on screen (straight line or curve) or multiple discrete point by hardware and software means, such as: conventional mouse, touch-screen, can also be phonetic entry, gesture input etc.All discrete points can comprise additional information, such as: tandem.

(13) each discrete input point corresponding for continuous route is converted to geographic position corresponding on map.

(14) these geographic position after conversion are preserved as new path point.

The path point of each section of continuous route that user draws can be used alone, also can be used in combination with other tracing point.For being used alone, can connect with line (straight line and/or curve) between the path point that each section of continuous route is corresponding.

For used in combination, the starting point of each section of continuous route and terminal as new tracing point, together with other tracing point existed before, can continue the interface renderings track utilizing map vendors.

As shown in figure 22, continuous route DE becomes a part for track, and in addition, the starting point D that continuous route DE is corresponding and E becomes new tracing point.Various ways can be utilized in the case to form new orbit segment, and namely D and B forms orbit segment BD, E and C forms orbit segment EC, such as:

1. for D and B, E and C reuse the interface of map vendors;

2. continue to draw new route between D and B, E and C, and form new route and tracing point;

3. directly connect D and B, E and C.

(15) complete path drawing, exit manual path pattern.

Example 4,

Usually, in order to give the photo point of addition information of shooting, needing the location-based service of opening system software, may also need to allow application acquisition positional information of taking pictures simultaneously.Such as: on iOS or Android, user needs the positioning service of opening system, and allows specific application to use this service.But there is a problem at present: the positional information that the API that application program is directly provided by system obtains has error.And the electronic chart application that map vendors provides, such as: apple map or Google Maps, using after identical API obtains positional information, the correct algorithm carried usually all can be used to eliminate this error, thus provide geo-location service more accurately for user.The service of this class generally mainly for be the electronic chart application of those specialties, for those application that are common, non-electronic map to the trouble that obtains positional information accurately and compare and expense.

For this reason, the method that in this example, proposition one is new is helped application that is common, non-electronic map and is obtained positional information equally accurately, and concrete steps are as follows:

(20) integrated electronic Map OCX in shooting interface, control can be set to visible or invisible, concrete as Figure 23.

(21) in the predefined moment, current location information is obtained by electronic chart control.The predefined moment can be: find a view, and presses shutter key shooting; If Map OCX is visible, manually selects place and confirm.

The mode and other modes that are obtained positional information by electronic chart control, when specific implementation, can be combined use by this step.Such as: when current location information cannot be obtained by electronic chart control, the API that use system provides can be transferred.

(22) after shooting action completes (such as: press shutter key), the image data of photo is preserved together with the positional information obtained by Map OCX.Positional information can be kept at photo files inside, such as: as EXIF meta-data preservation, or preserves independent of photo.

The scheme that this example provides can be applied in above-mentioned three examples, to realize geographical location information when accurately obtaining photograph taking.

Dynamic travel notes scheme in above-mentioned four examples, equally also can be applicable to other digital media content, as digitized word, figure, sound, video image and animation etc.
