Though present embodiment has been described the map datum that is divided into 456 cut zone with the latitude of the longitude interval of 1 degree and 40 minutes (2/3 degree) at interval, for convenience, it is thinner that this map datum can be divided.In practice, the length of the cut zone of this map is preferably along about 10 kilometers of parallel and warp.Corresponding to the cut zone of smaller szie, along the number increase of parallel and meridianal cut zone.
As shown in Figure 5, this map datum also comprises the landmark data table, these address date table storage location data are such as extension width, rectangular area coordinate and female data of the area coordinate (LM area coordinate) as the title of target mainly theme park, station and the school, the sign (ID) number that is assigned to each terrestrial reference, each terrestrial reference that is arranged in each cut zone, each terrestrial reference or be subordinate to data.That is, this landmark data table is stored in the data (LM name data) of the place name of terrestrial reference in the LM title part, and the latitude and the longitude data in locations and regions data and each place is stored in the LM area coordinate part as the terrestrial reference area co-ordinate data.In this enforcement profit, regional A (11,8) will be described as an example, wherein, have theme park α, have Ferris wheel β and roller-coaster γ in the α of this theme park.
The ID of theme park α number is #100, and Ferris wheel β and roller-coaster γ ID number is respectively #101 and #102.Because Ferris wheel β and roller-coaster γ are positioned at theme park α, thus can think compatibility relation between their terrestrial reference be for theme park α be subordinate to or attached.Therefore, ID # 101 and the #102 of Ferris wheel β and roller-coaster γ are stored in being subordinate in the data division of theme park α, and the ID # 100 of theme park α is stored in female data division of Ferris wheel β and roller-coaster γ.
Fig. 6 schematically shows the area data of theme park α with the 2-D top view.Theme park α is the terrestrial reference with pentagonal regions, thereby indicate each latitude on five summits and coordinate (the α x1 of longitude, α y1), (α x2, α y2), (α x3, α y3), (α x4, α y4), the data of (α x5, α y5) are stored in the LM area coordinate part of theme park α of landmark data table.The zone that is surrounded by the line that extends between these summits can be known as the terrestrial reference zone of theme park α.This area data has also defined the elongated area of theme park α, and this elongated area is extended preset width from the terrestrial reference zone of theme park α to all directions.In the present example, the extension width of the elongated area from the terrestrial reference zone to theme park α is 5 meters.Attention: the extension width of each terrestrial reference is stored in the extension width part of landmark data table shown in Figure 5.In addition, this landmark data table comprises the data of the rectangular area of each terrestrial reference, or claims the minimum boundary rectangle of this rectangular area for each terrestrial reference, and it is external in the elongated area of each terrestrial reference.Specifically, the latitude on four summits of the rectangular area of indication theme park α and the coordinate data of longitude, i.e. (R α x1, R α y1), (R α x2, R α y2), (R α x3, R α y3) and (R α x4, R α y4) be stored in the rectangular area coordinate part of theme park α of landmark data table.
Fig. 7 schematically shows the area data of Ferris wheel β with the 2-D top view.Ferris wheel β is the terrestrial reference with rectangular area, so indicate each latitude on four summits and coordinate data (the β x1 of longitude, β y1), (β x2, β y2), (β x3, β y3) and (β x4, β y4) be stored in the LM area coordinate part of Ferris wheel β of landmark data table.The zone that is surrounded by the line that extends between these summits can be known as the terrestrial reference zone of Ferris wheel β.This area data has also defined the elongated area of Ferris wheel β, and this elongated area is extended preset width, for example 3 meters from the terrestrial reference zone of Ferris wheel β to all directions.In order to define the rectangular area with summit external Ferris wheel β on latitude direction and longitudinal of the elongated area of Ferris wheel β, the latitude on four summits of the rectangular area of indication Ferris wheel β and the coordinate data of longitude, i.e. (R β x1, R β y1), (R β x2, R β y2), (R β x3, R β y3) and (R β x4, R β y4) be stored in the rectangular area coordinate part of Ferris wheel β of landmark data table.
Fig. 8 schematically shows the area data of roller-coaster γ with the 2-D top view.This roller-coaster γ is hexagonal terrestrial reference, so indicate each latitude on six summits and coordinate data (the γ x1 of longitude, γ y1), (γ x2, γ y2), (γ x3, γ y3), (γ x4, γ y4), (γ x5, γ y5) and (γ x6, γ y6) is stored in the LM area coordinate part of roller-coaster γ of landmark data table.Can be known as the terrestrial reference zone of roller-coaster γ by the line area surrounded of between these six summits, extending.This area data has also defined the elongated area of roller-coaster γ, and this elongated area is extended preset width, for example 3 meters from the terrestrial reference zone of roller-coaster γ to all directions.In order to define the rectangular area with summit external roller-coaster γ on latitude direction and longitudinal of the elongated area of roller-coaster γ, the latitude on four summits of the elongated area of indication roller-coaster γ and the coordinate data of longitude, i.e. (R γ x1, R γ y1), (R γ x2, R γ y2), (R γ x3, R γ y3) and (R γ x4, R γ y4) be stored in the rectangular area coordinate part of roller-coaster γ of landmark data table.
Return with reference to figure 1, when storage card 8 was connected on the CPU 11 of personal computer 4, view data was read and is imported into the CPU 11 from this storage card 8 with related position data.For example, the position data of input has been indicated the camera position P1 that is positioned at latitude 35.7 degree longitudes 139.7 degree.Then, CPU 11 finds data from the map datum of ROM 12, to determine to comprise the cut zone of this camera position P1.Attention: this storage card 8 is connected to CPU 11 by from digital camera 3, taking out in storage card 8 and the unshowned memory card slot with storage card 8 insertion personal computers 4.
Specifically, in order to determine to comprise the cut zone of input position P1, subtract the latitude (=30 degree) of the starting point of map with the latitude of camera position P1 (=35.7 degree), subtract each other the value (=5.7 degree) of acquisition and removed by the latitude angle of a cut zone (=2/3 degree).Then, merchant's (=8.55) fraction part is omitted.The numerical value of Huo Deing (=8) has been indicated the cut zone that comprises camera position P1 like this, i.e. the serial number of the shadow region among Fig. 2, this serial number are to count to get along meridian from beginning regional A (0,0) beginning.That is, the cut zone that comprises camera position P1 one of is confirmed as on the meridian direction from the Section Eight territory that begins regional A (0,0) beginning.
Meanwhile, deduct the longitude (128 degree) of map starting point, subtract each other the value (11.7 degree) that is obtained then and removed by the longitude angle of a cut zone (=1 degree) with the longitude of camera position P1 (139.7 degree).Then, merchant's (11.7) fraction part is removed.The numerical value of Huo Deing (=11) has been indicated from beginning the serial number of the target cut zone that regional A (0,0) beginning counts to get along latitude line like this.Therefore, comprise that the target cut zone of camera position P1 is confirmed as regional A (11,8), this zone A (11,8) is the 11st position from the weft direction that begins regional A (0,0) beginning and the zone of the 8th position on the meridian direction.Therefore, by being the calculating of the latitude and the longitude of camera position, determined to comprise the target cut zone of camera position based on the input position data.When the ferret out cut zone, to compare with the situation that input position data and all cut zone of map datum are compared, this method has been saved the time that is used to search for the target cut zone that comprises camera position.
After having determined the target cut zone, CPU 11 is with reference to the landmark data table search terrestrial reference relevant with camera position P1.Because camera position P1 is confirmed as being included among the cut zone A (11,8), so CPU 11 only searches for those terrestrial references that are positioned among the regional A (11,8).In the present example, as shown in Figure 6, suppose that camera position P1 is positioned at the Ferris wheel β of theme park α.
At first, in the rectangular area that is positioned at the terrestrial reference among definite cut zone A (11,8), CPU11 retrieves one of them rectangular area that comprises camera position P1 at least.Therefore, in this example, the rectangular area of the rectangular area of theme park α and Ferris wheel β is retrieved.
Next, CPU 11 calculates the distance L α 1 in the LM zone from camera position P1 to theme park α and the distance L β 1 in the LM zone from camera position P1 to Ferris wheel β.Specifically, CPU 11 at first use judge a point be within the polygon or outside known method judge camera position P be within the LM zone at terrestrial reference or outside.If camera position P is within the LM zone, then the distance L from camera position P to the LM zone is retained as zero.Otherwise the bee-line from camera position P to the LM zone is confirmed as distance L.Because camera position P1 is positioned at the Ferris wheel β of theme park α, so the distance L β 1 in the distance L α 1 in the LM zone from camera position P1 to theme park α and the LM zone from camera position P1 to Ferris wheel β is confirmed as zero.
When the distance L of definite existence from camera position P to the LM zone is a plurality of terrestrial reference of zero, CPU 11 checks female data division of these terrestrial references and is subordinate to data division, be theme park α and the Ferris wheel β in this example, to determine the compatibility relation between these terrestrial references.Then, in these terrestrial references, be stored in a terrestrial reference in female data division of other terrestrial reference for its ID number, promptly the theme park α in this example is deleted from candidate.Therefore, Ferris wheel β is selected as the terrestrial reference (latitude 35.7 degree, longitude 139.7 degree) of camera position P1.
Next, the LM name data of the terrestrial reference that CPU 11 will select at last outputs to LCD 14, and to show the title of this last terrestrial reference of selecting, promptly " the Ferris wheel β " in this example is used as the camera position of photographic images.Meanwhile, the LM name data of the terrestrial reference that CPU 11 will select at last is associated with the view data of related position data, and they are write among the RAM 13.
If it is not such camera position of zero that the position data of input is represented the distance in any one the LM zone from camera position to any one terrestrial reference, then CPU 11 determines that this camera position is outside any one LM zone of the cut zone of determining.For example, if the position data of input represents to be arranged in the camera position P2 that still is positioned at the elongated area of this theme park α outside the α of theme park, as shown in Figure 6, then CPU 11 selects theme park α to be used as the terrestrial reference that its rectangular area comprises camera position P2.Next, CPU 11 computed range L α 2, this distance L α 2 are the bee-lines in the LM zone from camera position P2 to theme park α.Thereafter, CPU 11 compares the extension width of the theme park α in the extension width part of distance L α 2 and the theme park α that is stored in the landmark data table.If distance L α 2 does not surpass the extension width of theme park α, then CPU 11 determines that theme park α is the last terrestrial reference of selecting, and the LM name data of theme park α is outputed to LCD 14, to show that " theme park α " is as camera position.Meanwhile, in this example, the terrestrial reference that CPU 11 will select at last, promptly the LM name data of theme park α is associated with view data, and they are write among the RAM 13.
In addition, distance L α 2 greater than zero but terrestrial reference recently be the extension width of the theme park α in this example with interior situation under, CPU 11 can will be positioned near the LM name data of those terrestrial references of camera position P2 according to the order from beginning recently, promptly the order of " theme park α ", " Ferris wheel β " and " roller-coaster γ " outputs to LCD 14, thereby shows that these terrestrial reference names are referred to as camera position.In this case, CPU 11 is associated the LM name data of these terrestrial references with view data, and they are write among the RAM 13.
, the position data of input is positioned at the camera position P3 within the rectangular area of theme park α if having represented to be positioned at outside the elongated area of theme park α, as shown in Figure 6, then CPU 11 selects theme park α to comprise the terrestrial reference of camera position P3 as its rectangular area.Next, CPU11 computed range L α 3, this distance L α 3 are the bee-lines in the LM zone from camera position P3 to theme park α.Thereafter, CPU 11 compares distance L α 3 with the extension width of theme park α.Because distance L α 3 is greater than the extension width of theme park α, CPU 11 is not defined as theme park α the last terrestrial reference of selecting.That is, judge that camera position P3 is in office and where mark outside.In this case, CPU 11 outputs to LCD 14 with the message data of camera position outside main terrestrial reference of this image, thereby makes LCD 14 show this message.Meanwhile, CPU11 is associated the data of this message with view data, and they are write among the RAM 13.
If exist its rectangular area to comprise a plurality of terrestrial references of camera position P, then only to camera position P to target distance L recently and recently the target extension width the two compare.
The process flow diagram that will contrast Fig. 9 is now described the operation of camera position search system 2.As digital camera 3 photographic images (S1: during step 1), program activation signal is fed back to GPS counter 10 by slave controller 7, thereby GPS counter 10 activates calculation procedure comes the calculating location data with the electric wave that receives according to antenna 9, i.e. the latitude of current camera position and longitude (S2: step 2).The position data of calculating is sent to controller 7, thereby controller 7 is stored in the view data of photographic images and position data from GPS counter 10 in the storage card 8 explicitly.
When storage card 8 is connected to CPU 11, CPU 11 (S3: step 3) is read and delivered to view data and the position data that is associated from storage card 8.Then, CPU 11 selects a cut zone (S4: step 4) who comprises by the camera position of the position data appointment of importing from the map datum retrieve data of ROM 12 in all cut zone of next map datum from be stored in ROM 12.For example, if the position data of input is specified the camera position P1 that is positioned at latitude 35.7 degree and longitude 139.7 degree, then cut zone A (11,8) is selected.
Next, CPU 11 retrieves the landmark data that is arranged in selected cut zone from the landmark data table, to select at least one rectangular area that comprises camera position (S5: step 5).To camera position P1, the rectangular area of theme park α and Ferris wheel β is selected as Search Results.
Next, CPU 11 calculates from camera position to the distance L (S6: step 6) that is included in each the LM zone in the selected rectangular area.For example, the distance L β 1 in the distance L α 1 in LM zone and LM zone from camera position P1 to Ferris wheel β from camera position P1 to theme park α.
Thereafter, to judge whether to exist its distance L be any terrestrial reference (S7: step 7) of zero to CPU 11.When the distance L of definite existence from camera position P to the LM zone is a plurality of terrestrial reference of zero, for camera position P1, CPU 11 checks these terrestrial references, i.e. female data division of theme park α and Ferris wheel β and be subordinate to data division, thus determine the compatibility relation between this terrestrial reference.Then, in these terrestrial references, the terrestrial reference in female data division that is stored in other terrestrial reference for its ID number, promptly the theme park α in this example is by deletion (S8: step 8) from candidate.Therefore, the last selected (S9: step 9) of terrestrial reference as camera position P1 of Ferris wheel β.
Next, the LM name data of the terrestrial reference that CPU 11 will select at last outputs to LCD 14, with the title of the terrestrial reference that shows last selection, and the LM name data of the terrestrial reference that will select at last and view data and position data thereof are stored in (S10: step 10) among the RAM 13 explicitly.
On the other hand, if judge and where to take office from camera position that the distance L in any LM of target zone is not zero (S7), then for camera position P2, CPU 11 selects its rectangular areas to comprise the terrestrial reference of camera position, i.e. theme park α.
Next, CPU 11 compares the extension width of distance L and selected terrestrial reference, for example, the distance L α 2 in the LM zone from camera position P2 to theme park α and the extension width of theme park α is compared (S11: step 11).If distance L does not surpass the extension width of selected terrestrial reference, then CPU 11 determines that selected terrestrial reference is as the last terrestrial reference of selecting.Therefore, for camera position P2, theme park α is selected at last as its terrestrial reference (S9).
Then, CPU 11 outputs to LCD 14 with the LM name data of theme park α, is used as camera position to show " theme park α ".Meanwhile, CPU 11 has indicated the view data of camera position P2 to be associated with its position data the LM name data of theme park α, and they are write (S10) among the RAM 13.
If the distance L from camera position to nearest terrestrial reference zone is confirmed as greater than this target extension width (S11) recently, then the situation with camera position P3 is identical, and CPU 11 judges that these camera positions are not included in mainly target (S12: step 12) in any one.In this case, CPU 11 is that message data outside main terrestrial reference outputs to LCD 14 with the camera position of this image, so that LCD 14 shows these message.Meanwhile, CPU 11 is associated the data of this message with view data, and they are write (S10) among the RAM 13.
As description up to now,, found the cut zone of the camera position that comprises photographic images by calculate the latitude and the longitude of the camera position of storing explicitly with the view data of photographic images based on the position data of input.Therefore, situation about comparing with all cut zone of position data and map datum that will input comparatively speaking needs to spend the less time search for the cut zone that comprises camera position.
In addition, the landmark data table comprises the data of LM area coordinate, extension width and rectangular area coordinate, thereby even when camera position is present in the elongated area of terrestrial reference, can determine that also camera position is included in that terrestrial reference.Therefore, even produce error because the degree of accuracy that map datum or GPS calculate is not enough, if this error in the scope of extension width, then this error is absorbed, thereby retrieves correct terrestrial reference.To the camera position outside terrestrial reference take but comprise this terrestrial reference image as a setting, if this camera position in the elongated area of this terrestrial reference, then camera position terrestrial reference search system 2 is selected the camera position of these terrestrial references as photographic images.
Because the title of the last terrestrial reference of selecting is presented on the LCD 14, so the user can see the title of the terrestrial reference relevant with photographic images immediately.Because this view data is associated with position data when view data is written into storage card 8, and when view data is written into RAM 13, its LM name data with the last terrestrial reference of selecting is associated, so the user can be only by reading the camera location that its view data is seen this photographic images from RAM 13.When having selected a plurality of terrestrial references for an image, and when their name data and view data are stored among the RAM 13 explicitly, the user can be subsequently selects one in these terrestrial references, and the LM name data of that terrestrial reference of this view data and selection is write among the RAM 13 explicitly again.
