-(randomly) one or more wireless launcher/receivers, in order to allow communication via mobile communication and other signal and data network (for example, Wi-Fi, Wi-Max GSM etc.).
The effectiveness of PND mainly shows the ability that it determines the route between homeposition or current location and the destination, the destination can by the user of calculation element by in the many kinds of distinct methods any (for example, by postcode, street name and number) import, and the destination that can be previously stored well-known, favorite or be recently.Usually, PND calculates the software of " best " or " the best " route that sets out between address location and the destination-address position and enables by being used for according to the map data." best " or " the best " route is based on that predetermined criterion determines, and the fastest or minimal path not necessarily.Guide driver institute along the selection of route may be very complicated, and selected route can consider existing, prediction and dynamically and/or the traffic that wirelessly receives and road information, about the historical information of road speeds and driver self preference for the factor of definite road alternate item.In addition, but described device watch-keeping road and transportation condition, and provide or select to change route, the route that on this route, will be left because of the condition that changes.Real-time traffic surveillance based on various technology (for example, mobile calls, fixedly camera, the tracking of GPS fleet) just is being used for discerning traffic delays and information being fed in the reporting system.
Guider can be installed on the instrument panel of the vehicles usually, but also can form the part of the airborne computer or the car radio of the vehicles.Guider also can be hand held system (a part), for example PDA (personal navigation apparatus) media player, mobile phone or analog, and in these cases, by means of software being installed in the normal function that calculates and expand hand held system on the device with execution path along the navigation of the route that is calculated.In any case in case calculated route, the user just selects the desired route that calculates with the guider interaction with (randomly, from proposing list of routes).Randomly, the user can intervene or the guideline selection course, for example by specifying for specific route, should avoid or must follow some route, road, position or criterion.A major function that is provided is provided for the route calculation aspect of PND, and is another major function along the navigation of this route.During the route guidance that calculates, PND provides vision and/or can listen instruction, arrives the terminal point of described route in order to guide the user along selected route, and this terminal point is desired destination.PND usually during navigating on screen displayed map information, this information regular update on screen, make the current location of shown cartographic information indication device, and therefore represent the current location (navigating) of user or user's the vehicles if device is used in the car.Be presented at the current setting position of icon ordinary representation on the screen, and placed in the middle, wherein also show cartographic information current and road on every side and other map feature.In addition, randomly, can be above shown cartographic information, below or show navigator information in the status bar of a side, the example of navigation information comprises that the current road that need choose from the user is to next distance that departs from, the described character that departs from may be by the further icon representation that shows the particular type (for example, left-hand rotation or right-hand rotation) that departs from.Also definite content, duration and the sequential that can listen instruction of navigation feature can guide the user along route forward by means of described instruction.As understanding, simple instruction such as for example " turn left behind the 100m " needs magnanimity to handle and analyze.As previously mentioned, the interaction of user and device can be passed through touch-screen, perhaps additionally or alternati the telepilot by being installed in the jociey stick place, by voice activation or by any other proper method.
The prior function that described device provided is the automatic route re-computation under following situation:
-during the route guidance that had before calculated, the user departs from described route,
The route that-real-time traffic condition indication substitutes will be more favourable, and described device has suitable function with these a little conditions of automatic identification, or
If-user is for any former thereby initiatively cause device execution path re-computation.
Also known permission comes calculated route by user-defined criterion; For example, the user may prefer device and calculate scenic route, may wish perhaps to avoid that traffic jam may take place, expectation can take place or the current any road that is just taking place.Device software will then calculate various routes, and more favor comprises the route of a highest number focus (being known as POI) (be noted as (for example) beautiful scenery is arranged) on the way, perhaps use the canned data of the transportation condition that is just taking place on the indication specified link, the grade of the delay that causes by possible obstruction or because of obstruction comes the route that calculates is sorted.Other also is possible based on POI with based on the route calculation and the navigation criteria of transport information.
Although route calculation and navigation feature are very important to the overall utility of PND, but described device might be used for purely information shows or " freely driving ", wherein only show the cartographic information relevant, and wherein do not calculate route as yet and install current in the execution navigation with current setting position.This operator scheme often applicable to known as the user advance will along route and do not need to navigate when auxiliary.
More recently, PND has been manufactured with the integrated digital camera that comprises one or more charge-coupled device (CCD)s (CCD), and therefore can catch digital photograph images, and described image then is stored in the non-volatile apparatus storer usually.As the conventional practice of dedicated digital cameras, (for example, USB) connect, these a little images can be downloaded on user's the PC or other digital picture storehouse subsequently by means of the physics between PC and the device.As mentioned, can store the image in the local nonvolatile memory in the device, or be stored in can load and unload media store card (for example, secure digital or SD card) or any other this type of can load and unload in the Digital Media (for example, flash memory).The specific advantages that digital camera is integrated among the PND is, except the standard markup information that belongs to these a little images usually (for example, time and date) outside, the digital picture of being caught also can mark the specific location information that the with good grounds gps signal that is just being received or received by device recently by device calculates.In particular, by
The S90i device of making and selling comprises this facility.
A kind of service also is provided, the image through the mark of geographical space in advance of POI can be downloaded from image server for the PC (PND is connected to described PC) via the user by this, and can be stored in the storer of device, for when setting position is determined to be in the predetermined proximity threshold value of specific POI, being presented on the screen of device after a while.Another useful feature of the storage of the specific image through geographical space mark of POI is, can select described image from storer, as a kind of approach of the identification destination of wanting, perhaps as the way point of wanting along the route that arrives the selected destination of user that substitutes.The search of this facility and standard P OI and select roughly the same, for standard P OI, only storing text message is as a part-only difference of the map datum that uses in navigation, route calculation and the free driving model of PND, the demonstration of the photo by specific POI, the user is the specific POI of identification on screen immediately.
Although these a little less important or subsidiary characteristics are favourable and have strengthened overall user experience that the navigation feature that described feature is not provided device does not provide any enhancing except the number that enlarges the POI that can insert.
For example long-range Atlas NV (TeleAtlas NV) and NavTech current map datums such as (NavTeq) provide company to produce the digital map data that is one or more basic data file forms, PND extracts the figured information that is used to create geographic entity (for example, road, buildings, railway and other continental embankment and POI) from described digital map data.This information is presented on the screen of device, and almost constantly is refreshed, and thinks that the user provides current location and the peripheral region changing map with reference to the roughly static figure vehicles designator of the centre that is also shown in screen.The degree of the details of being showed in the map depends on many factors, and the grade of the details that is provided by the basic map data file of the special ratios chi, gait of march of the map of being selected by the user and locality that (certainly) is used for the current place of device is provided.For instance, when the user is passing when advancing on the highway of rural, on the screen of device, only show less relatively information, and advance when passing the city, much bigger comparatively speaking detail grade can be provided on screen when (and so very slowly) on the road that the user is blocking up.
In a kind of situation after this, because the user can make the roadside that is shown on the screen or bigger in the relevant possibility of appreciable corresponding physical features when the specified link of being discussed is driven with it based on the feature of road, so the navigation feature of coming intensifier to provide by the more detailed information of demonstration on screen.A shortcoming that derives from the data file of current map provider is, its detail grade only with each in succession the version issue increase.Thus, these situations only take place comparatively speaking once in a while, and therefore, because the change of the normal road layout that takes place and enter the enforcement of restriction in city and (on less degree) area, suburbs, cartographic information might be out-of-date.In addition, map datum does not comprise the change of cambic road usually, for example may reduce or change or be that the road of car lane becomes the special-purpose road change that causes of pedestrian through mapping before because of road engineering, track.
Target of the present invention is for providing a kind of PND or navigational system, a kind of method and a kind of computer program of using described PND of control or navigational system of operating described PND or navigational system, improve system together with a kind of map datum, described map datum improvement system allows the PND with camera function to use the numerical information of catching of taking a picture to strengthen the base map data file that described device provides its navigation feature by this.

Referring to Fig. 5, show overview according to system of the present invention, described system comprises the PND on the vehicles of being installed in camera function.Specifically, the vehicles 500 comprise the PND 502 that is installed in usually on the instrument panel.Show typical the layout in the picture 504, can see that wherein PND 502 and driver see through the visual field 506 of the windshield of automobile, the described visual field comprises traffic lights 508.It is desirable to, PND 502 possesses integrated digital camera or other captured digital image device, and it is operated under the control of the instead of software program that is installed on the function software on the described device or carries out thereon.In of the present invention one desirable especially feature, this software comprises: option, the user can select conventional camera mode by this, under conventional camera mode, as can using conventional digital camera, hold usually and use as described in device; And alternative selection, wherein can under the free image trap mode, use described device, as contemplated among Fig. 5.Under this operator scheme (device is being determined to select this pattern automatically behind its its erecting device that has been attached to the indication of 510 places).
In one embodiment of the invention, catch Digital Image Data continuously, make that the continuous Digital Image Data stream that is similar to stream-type video can be used for the processing electron device of device along with the vehicles move via camera.In alternate embodiment, the seizure of Digital Image Data periodically took place with the relatively short cycle (for example every the several seconds), made the Digital Image Data of q.s be caught to allow to that described data are carried out pattern or process identification technology by device.Applied specific identification technique is one in many available techniques, but in principle, described technology is used one group of numeric field descriptor of being stored or object definition, and it describes the common object of fundamental sum, for example, traffic lights, street lamp, pavement marker and other continental embankment or roadside continental embankment based on road.Image or process identification technology also periodically or constantly take place the Digital Image Data that receives, in any case but, whether foundation recognizes any one in many objects in the view data that is captured when the view data that is captured is just processed, the processing of the view data that is captured provides the positive or negative result.In picture 512, find out traffic lights feature 508 by identification, and device can store then through the message of high compression or other data (as the indication of 514,516 places), its expression is by the type of the object of identification with to certain indication of its geospatial location.
About be included in the geospatial location information in these data with object identifier, there is variety of option.An option is that supplying apparatus is recorded in current position coordinates or the GPS information when catching numerical information, and wherein correlated characteristic is by pattern identification or the identification of other image processing techniques.The replacement scheme that is used for record position information is that setting position when causing device based on captured digital image or device last stored known location (it is proofreaied and correct the roughly setting position so that captured digital image to be provided on demand) and carried out other position and handle routine, described other processing routine is drawn together other Flame Image Process routine, this other Flame Image Process routine to the feature discerned actual during with respect to captured digital image or roughly the position of setting position make approximate.Certainly, more than all under the situation, correlation time of captured digital image and therefore determine the current reality of device or the time of approximate location is the digital picture of the being caught time when containing the feature of identification to some extent.
Although it is desirable to, but be used for determining being the time of the seizure of the Digital Image Data that contains the identification feature just that this may be always unfeasible, and can use time threshold certainly relevant correlation time actual or roughly setting position.Certainly, this will reduce the degree of accuracy of the derivation position that can determine current reality or institute's identification feature that roughly setting position and (if suitably) are relevant, but these a little accuracy reduce and can come balance by described overall map data update system hereinafter.
Once more referring to Fig. 5, in device 502, when enabling suitable " watch-keeping " option (wherein, digital camera integrated or that be associated is caught Digital Image Data continuously or periodically, and it is carried out one or more pattern identification techniques) time, the amount of the data of being stored will increase pro rata with the number of the roadside object of being discerned in the view data of being caught.In the suitable time, for example when more the amount of new data reaches a certain size, when perhaps being used for (wirelessly or the USB that has connected the PC of the Internet via arrival connect) with facility that remote server 518 is communicated by letter than standard when device detects, described device causes new data more to the uploading of described server, and described server authentication has captured digital image and processing power from all and all received lastest imformations in order to the device of any institute storage update information of providing are provided.
Upgrade (comprise than other position coordinates and be distributed in position coordinates in one or more geographic position more thick and fast) for the received all that of authentication server, proving program is equivalent to ask average program and/or other statistics program effectively.For instance, the high distribution density of the more new data of place, indication road crossroad or traffic lights on every side will show the traffic lights at place, described crossroad undoubtedly.Making after this determines, authentication server is then created one or more map patches of comprising graphic icons (may " present "), and makes it can be used for being downloaded by the whole user library of specific device manufacturer after a while.As locating and to find out, can make traffic light icon 522 seem in assigned position, to be superimposed upon on the base map data 524 520 (they provide the example of the demonstration of cartographic information on device screen).
Described map patch be should control oneself the PC that connects the Internet (software has been installed on the described PC, for example can from the applicant buy with TomTom HOME
TMBe the software of brand, and described device can be connected to described PC) request download from server 518, perhaps alternatively, possess at device under the situation of radio communication or telecommunication capability, answer request under user's the order at the fixed time or equally and wireless downloading.Another replacement scheme is when the number of map patch or size reach a certain grade, with the map patch user library of " propelling movement " auto levelizer wirelessly.
In another alternate embodiment, the map patch may contain extremely limited data, for example position data of object indicator and correspondence and randomly other setting value or information.In this example, require PND or system to contain to be stored in a plurality of graphic icons in the storer, these a little graphic icons are through selecting to show with overlaying relation with shown map datum during navigating, so that the navigation of enhancing is provided for the user.Certainly, only just show described graphic icons at device during (, when the map datum that is just showing comprises ad-hoc location) near the position of relevant institute's identifying object.
Therefore, in a word: the chief component of system aspects of the present invention is:
PND has low-cost camera integrated or attached or that be associated
Camera and/or device possess the software of one group of predefine object of identification efficiently
The object of institute's identification is sent to authentication server together with position data
The object of server check institute identification and the validity of one or more map patches
The map patch downloads to PND from server via the Internet (randomly, wirelessly or via other communication network).
Should mention, the present invention can be equally applicable to vehicles integrated with guidance system.
Also should mention, software routines can be provided, its effectively assisted user aim at and wherein to be integrated with the PND of camera or wherein to provide camera and dock that PND is attached thereto and is situated between and connects.Certainly, can provide or be integrated under the situation of the navigational system in the automotive during fabrication, the camera that navigational system is communicated by letter with it may be provided as the part of automobile, and therefore, may consider to aim at and other problem (for example, providing suitably covering) to bright incident light.
For the use of pattern identification technique in PND and navigational system, there is multiple other possibility, it also should be regarded as being included in the present invention.For instance, for PND with camera function and navigational system, might create automatically for the map correction data that is transmitted in the future checking facility or other back-end processing facility.In this embodiment, the view data that is captured is carried out the pattern identification technique continuously or periodically, and the type of cognizable feature is road joint, layout and arrangement, indication along the road sign of the travel limits of road and in fact can be by the numerical data of being stored suitably any other feature or roadside feature based on road of expression, it is the part of basic map data file, perhaps follow-up patch or the POI data file for using in conjunction with described essence data files usually.
More particularly, can be applicable to the basic map data file or can be applicable under the situation of correction data of ancillary data file of basic map data file automatically creating, method of the present invention comprises the further step that the feature of institute's identification and basic map data (or attached descriptive patch or POI data file) is compared and discern the difference of a certain type therebetween, can usefully proofread and correct described difference.For instance, the modal difficulty of modern cartographic information is, previous for the less joint of " four crossway " type often by highway authorities, Local Committee or have the power to change the road structure in a certain place and other executive authorities of layout become annular joint.Another example can be the introducing at traffic lights or the formal formerly uncontrolled joint of joint place.
By means of the pattern identification technique of carrying out by PND or navigational system, device might determine automatically as install the particular type of discerning and be presented at the joint on the screen based on the basic map data or applicable to its traffic management measure be different from as be associated or integrating device camera at the volley the time (freely drive or navigation mode under) actual joint type or the traffic management measure seen.
Whole colony for device users, this feature can have bigger benefit, as comparing with using the map correction feature in the software that can be provided in device, most of users are general only interested in using described device to carry out the basic navigation that arrives the destination of wanting.Therefore, wirelessly launch data about its current location or previous position of advancing (option that is provided with when the starting first of device usually) if the user has indicated him to prepare to permit device automatically from described device, so device automatically the emission correction data need not further action.
Certainly, expression need be by being taked many in multi-form any by the data of this locality storage of the feature of pattern match technology identification, comprise in shape data, color data, pattern data, external appearance characteristic or the outline data etc. any one or more than one.In addition, Cun Chu data can comprise animated image in advance, as the part of pattern identification technique, described animated image and a plurality of image of catching one by one can be compared, and described a plurality of images of catching one by one provide the animation effect in those images jointly.
