Fig. 2 is the structural representation of guider in an embodiment;
Fig. 3 is the structural representation of guider in another embodiment.
Embodiment
In one embodiment, as shown in Figure 1, a kind of air navigation aid, the method computer program that places one's entire reliance upon, this computer program can run in the computer system based on Feng Luoyiman system, such as on-vehicle navigation apparatus, hand-held navigation position instrument, smart mobile phone, panel computer and palm PC etc.The method comprises the following steps:
Step S102, obtains the key word of input.
Step S104, obtains cartographic information, according to key word and cartographic information, obtains target location.
In one embodiment, can obtain the key word of inputting in text input frame, and search in the cartographic information getting, search the point of interest title corresponding with key word, and the positional information of obtaining point of interest title be as target location.In field of navigation technology, point of interest is the sign of the entity facility such as mark food and drink, public transport, subway, office building, market on electronic chart.For example, if the key word of user input is " Tengxun ", point of interest title correspondingly can be " Tengxun mansion ", and its corresponding positional information is the particular location at company of Tengxun office building place.In the present embodiment, a plurality of if the point of interest title corresponding with key word has, a plurality of points of interest corresponding with key word can be shown with the form of list, and the point of interest that obtains input chooses request, obtain point of interest and choose point of interest title corresponding to request.
In one embodiment, also can obtain the audio fragment of input, audio fragment be carried out to speech recognition and obtain key word.
In the present embodiment, user can give an oral account the title that it wishes the destination of arrival by microphone.After getting the audio fragment of this user's oral account, it is carried out to audio identification, obtain corresponding character string, and it is searched in cartographic information as key word, obtain corresponding point of interest title, and obtain its corresponding positional information.If the point of interest title finding has a plurality of, can pass through the plurality of point of interest title of voice broadcast, and obtain the selection instruction of user oral account, by this selection instruction is carried out to speech recognition, obtain the point of interest title that user chooses, thereby get positional information corresponding to point of interest title as target location.
Step S106, track and localization information.
Locating information is used the geographical location information at the actual place of user of guider.Can obtain its locating information by positioning system.Positioning system can be GPS(Globle Position Service, Global Positioning System (GPS)) system or big-dipper satellite positioning system etc.Owing to using the user of guider in mobile status, therefore need to locating information be followed the tracks of and be obtained.
Step S108, generates navigation information according to target location, locating information and cartographic information.
In one embodiment, can generate navigation information by navigation map matching algorithm, the navigation information of generation can be geographic position sequence.For example, navigation information can be by the locating information getting as initial, and comprise the crossing of process successively, finally usings target location as terminal.Wherein the positional information at crossing also comprises direction information.
Step S110, by voice broadcast navigation information.
In one embodiment, can regularly pass through voice broadcast navigation information.Report at set intervals navigation information.
The locating information that also can get according to tracking in one embodiment, is reported.For example, while can the distance in locating information and navigation information and between position, the immediate crossing of this locating information being respectively 100 meters, 50 meters, report this position, crossing, and report direction information corresponding to this position, crossing, thereby prompting user is ready about in advance, and user can not driven on wrong route because the speed of a motor vehicle has little time too soon to turn to.
In the present embodiment, also can obtain electronic chart, and on electronic chart, show navigation information.Make when user does not hear voice broadcast, still can check navigation information by display interface.
Electronic chart can be that off-line map can be also the satellite image of downloading in real time.Preferably, electronic chart can also be 3D map or streetscape map.3D map or streetscape map more approach the actual residing environment of user, thereby can make user be had gained some understanding in own residing position and navigation information rapidly.
In one embodiment, also can obtain real-time road condition information, traffic light status information and/or drive parameter information according to navigation information, by voice broadcast real-time road condition information, traffic light status information and/or drive parameter information.
Real-time road condition information is real-time road maintenance situation, vehicle congestion condition and road surface situation etc.Road maintenance situation is whether certain route is in maintenance construction state and can not pass through, vehicle congestion condition is the time span that whether has traffic congestion situation and blocked up on certain route, the road surface condition in damaged that pavement behavior cause due to weather or other factors.
Traffic light status information i.e. the situation of the traffic lights corresponding with position, crossing in navigation information, can comprise number, state and the current red light duration separately of current traffic lights.
In using the application scenarios of off-line map, owing to can not comprising above-mentioned real-time information on off-line map, thereby make user's selection schemer more exactly.
In the present embodiment, real-time road condition information and traffic light status information can be stored on server.Can obtain real-time road condition information from the real time propelling movement of server download or reception server.
Drive parameter information can comprise travel speed, estimated time of arrival (ETA) etc.The locating information that can get according to tracking and the duration calculation of tracking obtain drive parameter information.
Further, also can revise navigation information according to real-time road condition information, traffic light status information and/or drive parameter information.
For example, can exclude the route that road conditions are poor or traffic lights are more according to real-time road condition information, traffic light status information and/or drive parameter information, thereby revise navigation information.Preferably, can voice message user whether modify, if so, modify, if not, maintain former navigation information.
In one embodiment, the acquisition of information interest point information corresponding with locating information according to the map also, by voice broadcast interest point information.
If user is in mobile status, following the tracks of the locating information getting can change, when obtaining near the interest point information of following the tracks of the locating information getting, and voice circular.For example, if user when driving condition, the points of interest such as restaurant, supermarket, office building and market that can its approach of voice broadcast.Make user in driving procedure, do not need the facility of periphery too to pay close attention to, thereby can be absorbed on driver behavior, improve security.
