Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention the embodiment of the invention discloses a kind of air navigation aid and terminal, can guarantee user when lost accurately, promptly make a return voyage.Following examples are elaborated respectively.〃
Refer to Fig. 1, Fig. 1 shows the process flow diagram of a kind of air navigation aid that the embodiment of the present invention provides.As shown in Figure 1, this air navigation aid can comprise the following steps:
S101: pass through architecture;
Particularly, can search for base station signal around, according to the base station signal searching, and by architecture method, calculate the positional information of user at current time, for example, when the base station signal number searching is 1, can calculate by field intensity localization method user's current location information, when the base station signal number searching is 2 (while searching the signal of two base stations), can be by arriving angle (Angle of Arrival, AOA) localization method is calculated user's current location information, when the base station signal number searching is 3 (while searching the signal of three base stations), can (Time Difference of Arrival poor by time of arrival, TDOA) localization method is calculated user's current location information,
S102: in conjunction with the travel track of motion sensor recording user;
Particularly, can for example, by (utilizing in user that motion sensor the obtains schedule time before current time, in 20s) direction of motion and move distance, and user is in the positional information in the moment early than the current time schedule time, user by architecture is revised in the positional information of current time, for example, when user's current location information is going out of calculating by field intensity localization method or AOA method, this positional information is to owe accurately, therefore, can be by user the positional information in the moment early than the current time schedule time, and direction of motion and move distance in the schedule time of the user that obtains of motion sensor before current time, utilize difference algorithm etc., calculate the displacement in the schedule time of user before current time, thereby draw the accurate location information of user at current time, finally revised user can be recorded in user's travel track in the position of current time.In addition, by revised user after the position of current time is recorded in described user's travel track, also can sense terminals whether there is the operation of taking pictures, if detect, there is the operation of taking pictures, the positional information of recording user when carrying out shooting operation and the direction of taking pictures, the direction of taking pictures can detect by direction sensor, then also can, whether for example, by motion sensor senses user, have a rest in traveling process, if detect, user is expert at has a rest in process; Record positional information and the time of having a rest of described user when rest.
S103: when receiving the definite control signal of making a return voyage of user, export information to user, so that user is maked a return voyage according to travel track according to user's current location and travel track;
In step S103, when user finds that lost preparation is maked a return voyage according to former road, when terminal can receive the definite control signal of making a return voyage of user, then terminal can be exported information to user according to user's current location and travel track, so that user is maked a return voyage according to travel track, particularly, can pass through architecture method, and the current position that obtains user in conjunction with motion sensor, judge on the travel track before this whether recording at step S101 the current position of user, if the current position of user is not on the travel track recording before this, in the time of can reminding user rollback, there is deviation, and the travel track that can record according to the current position of user with before this calculates correction route, the correction route drawing is prompted to user.In addition, also can be when user Yan Yuan road be returned, can detect user and whether arrive the place that has the operation of taking pictures in the travel track recording before this, if detect, arrive the place that has before this operation of taking pictures, show the photo that the operation of taking pictures forms, and show the direction of taking pictures of operation of taking pictures, thus can make user search corresponding position by photo and the direction of taking pictures, more to guarantee the correctness of rollback route; Also can detect user and whether arrive the rest place in the travel track recording before this; if arrive rest place; export information to user; it was once rest place that this information is used for pointing out user herein; so that the vestige that user stays can check rest before this time, thereby more guarantee the correctness of rollback route.
In the air navigation aid providing at Fig. 1, can pass through architecture, in conjunction with motion sensor, obtain user's travel track, and can be when receiving the definite control signal of making a return voyage of user, according to user's current location and before this travel track output information of record to user, so that user makes a return voyage according to this travel track, thus can guarantee user when lost accurately, promptly make a return voyage.
Refer to Fig. 2, Fig. 2 shows the structural representation of a kind of terminal that the embodiment of the present invention provides.This terminal 20 can be, for example, and mobile terminal or navigation terminal etc.As shown in Figure 2, this terminal 20 can comprise architecture unit 201, track record unit 202 and the unit 203 that makes a return voyage, wherein:
