Fig. 2 shows the block diagram that is used for the method 200 of the destination of input route planning in the navigational system 100 of Fig. 1.Described method 200 comprises step 205 to 280.

In step 205, method 200 is in initial state.In step 210, receive picture, for example, by via interface 135 with corresponding data transfer to navigational system 100, perhaps by interchangeable storage medium, in this interchangeable storage medium, store picture and distribute to their position.This step needn't repeat for the execution once more of method 200.The picture that has the position of distribution also can be stored in the storer 160 that is used for image data, the execution that this can alternative steps 210.

Then, the width of cloth or the width of cloth picture that in step 215, on display 150, show the storer 160 that is used for image data.

Follow-up two

steps

220 and 225 are optionally and can be performed once, repeatedly or not carry out.The user checks picture in step 220, and this for example can comprise according to about different information (ascending order or descendings such as creation-time point, title, the distance) classification of picture, according to the standard manual of determining or automatically divide into groups, show the preview picture that dwindles, show information and the interpolation of distributing to picture or delete mark to picture.Picture is amplified on the display 150 in step 225, for example in order to show details in greater detail.If the picture and the display 150 that amplify do not match, the segment that then can Show Picture, the position of described picture segment can be moved about total picture subsequently.

Step 225 can be alternatively in step 220 the checking or and then in step 230, select picture or be chosen in objects displayed on the picture of repetitive picture.Under the situation of touch-screen, this selection is by realizing with finger or with the picture that the marking tools of input media 155 raps on the display 150.In another operation modification, this selection realizes by input media 155 in the corresponding way.Usually, every width of cloth picture only is assigned with a geographic position.Also can show a plurality of selectable objects in a width of cloth picture, described selectable object is assigned with other position separately.Combination also is possible, as long as distribute a position and distribute other position separately to the one or more objects that show on the picture to picture.So picture has been assigned with a plurality of positions, described a plurality of positions then be assigned to a plurality of objects on the picture.The user promptly can select picture as a whole also can be chosen in objects displayed on the picture.

Subsequent step 235 is chosen wantonly again to 255, and describes the confidence level of selected object.In step 235, carry out to the identification of the object in step 230, selected or to the identification of objects displayed on selected picture.Described object for example can be building or the sign that is used for the destination of route planning, and described picture can be for example shows object with the form of photo or stick figure.Described identification for example can comprise the determining and the size and the determination of ratio of object of detection, camera perspective of object edge.From these and the other information that draws by picture, can determine characteristic attribute for shown object, in step 240 according to their combinatorial search allocation database 140, the position of the object of being discerned to search.If found the position of the object of being discerned, then in step 245, itself and the position of distributing to described object are compared, and the distance between definite two positions.

In step 250, by determining whether described distance surpasses predetermined threshold value and estimate the distribution of described position to described picture.If described distance surpasses predetermined threshold value, if it is insincere in other respects perhaps to distribute to the position of described object, for example because the present bit of itself and navigational system 100 is equipped with very large distance, then in step 255, require the user that the position of distributing to described object is proofreaied and correct, perhaps at the object space of determining by step 240 with distribute between the position of described object and select.In another form of implementation, also can give tacit consent to the position of getting the object of being discerned or distribute to the position of the object that illustrates on the picture.Yet, still can export user reminding.

Under any circumstance, have believable position in follow-up step 260, the destination of the route planning of making navigational system 100 is got in described believable position.

In follow-up two same

optional step

265 and 270, the getatability inspection of the destination of execution path plan.Analyze in step 265, whether the destination of route planning can for example arrive by walking, bicycle, automobile, ship, aircraft or its combination by the pre-determined vehicles.The voice messaging of in step 270, exporting about determined getatability by voice output 115.In another embodiment, also can for example, indicate the destination of route planning to lack getatability by other device by mode vision or sense of touch or by its combination.If the destination of route planning can not arrive, just for example the combination by the vehicles selected in advance can not be near to nearer than pre-determined distance, then can require the user to be chosen in the destination of evading around the destination of original route planning.In step 275, carry out the route guiding of going to the destination of route planning or evading the destination subsequently.This method is in done state in step 280 subsequently.

Fig. 3 shows the method for the position being distributed to picture or object, and by described method, the picture that has a position of distribution can be provided for the method 200 among Fig. 2.Described method 300 comprises step 305 to 345, and can with method 200 related uses shown in figure 2, for example before or after it, wherein corresponding to step needn't repeat.Shown method 300 is suitable for implementing on the navigational system 100 in Fig. 1.In step 305, described method 300 is in initial state, and the subsequent step 310 to 330 that is used to select picture and the step 210 of method 200 are to 230 corresponding.These steps can be replaced by step 340, take new picture by camera 130 in step 340.In both cases, all in step 335, determine the current location of navigational system 100 or camera 130 subsequently by locating device 110.

Subsequent step

345 and 350 subsequently be again choose wantonly and relate to the geographic position of determining objects displayed on picture.In step 345, determine described on picture the distance and the direction of objects displayed so that obtain the relative position of object about camera position.Described distance for example can be determined according to the metamessage that is stored in (for example with the Exif data layout) in the numerical data with described picture.This metamessage can comprise the focal length of focus, focusing setting and the camera lens of camera, therefrom can determine the distance of object.The direction of object for example can be based on determining by the measurement of compass 120 or based on the other information that is stored in the data with described picture.In step 350,, determine the geographic position of described object based on the direction and the distance of the geographic position of the navigational system of in step 335, determining 100 with the relative navigational system of in step 345, determining 100 of described object.Should determine also can comprise the cartographic information of handling the storer 125 that is used for map datum, for example to be used for the confidence level test.

Subsequently, determined position is distributed to described picture or on described picture objects displayed.Be in done state in method described in the step 360 subsequently 300.
