Embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.
Embodiment one
Referring to Fig. 1, present embodiment provides a kind of localization method, and method is following:
Step 110: the star information of searching of obtaining locating terminal;
Step 120: judge this and search star information and whether reach the thresholding of searching the star signal;
Step 130: when reaching this thresholding of searching the star signal, switch station-keeping mode.
Present embodiment is judged this and is searched star information and whether reach the thresholding of searching the star signal through obtaining the star information of searching of locating terminal, when reaching this thresholding of searching the star signal, switches station-keeping mode.The effect of the buffer zone of searching star signalc threshold and map of combining position information, setting effectively makes the indoor and outdoor station-keeping mode realize the seamless accurate switching of indoor and outdoor station-keeping mode, has improved user's experience.
Embodiment two
Referring to Fig. 2, present embodiment provides a kind of localization method, and method is following:
Present embodiment is that the star signal is searched in the example conduct through the gps signal in the location of GPS in service, can comprise that also other are to search the station-keeping mode that star is a localization method.
Wherein, the positioning service that locating terminal provides in the present embodiment can provide the switching of station-keeping mode, and station-keeping mode comprises outdoor station-keeping mode and indoor positioning pattern; This just need rationally be provided with the switching time of above two kinds of station-keeping modes.
By being, the user is merged location and need be cut out the GPS location from outdoor to indoor the time, turns outdoor station-keeping mode to the indoor positioning pattern, otherwise, then need add the GPS location, change indoor positioning pattern is outdoor station-keeping mode.In the practical position operation, only rely on positional information of the prior art location, there is the orientation distance error in locating terminal, and its bearing accuracy can't guarantee.
By being, introduce that the thresholding of searching the star signal being set, specific as follows:
The drop-out value of setting this signal to noise ratio (S/N ratio) in the unit interval surpasses default value, and it is regarded as reaching the thresholding of searching the star signal;
It is specific as follows that gps signal is provided with its thresholding: surpass certain numerical value if search the decline of star signal unit time signal to noise ratio (S/N ratio), then it is regarded as reaching its thresholding.When gps signal descends suddenly; Can measure its signal to noise ratio (S/N ratio) also can descend suddenly; So we decide its thresholding through the numerical value of setting signal to noise ratio (S/N ratio) decline; Numerical basis actual needs that signal to noise ratio (S/N ratio) descends and experience produce, and setting the certain numerical value that surpasses that descends here is 10dB (decibel), and the unit interval is 0.3 second.When reaching this thresholding of setting, need the excision gps signal, the corresponding step 280A of locating terminal positions the switching of pattern.
Set this and search the satellite that the star signal searches out predetermined number, it is regarded as reaching the thresholding of searching the star signal;
Its thresholding of gps signal information setting is specific as follows: if search the satellite of some, then it is regarded as reaching the thresholding of gps signal, the number of setting the satellite of some here is 3 stars.
Be different from direct excision gps signal, in the process that gps signal adds, need certain star process of searching; That is to say, search the concrete setting of star signalc threshold this moment and need consider that the delay of GPS location adds, at this moment; Just not with the abrupt change of gps signal as the benchmark that changes, but to search out 3 satellites, the time point that really can carry out outdoor fusion location is as new benchmark; More help the accurate connection of indoor and outdoor station-keeping mode, avoided GPS to search the error that star postpones.When reaching this thresholding of setting, need to add gps signal, the corresponding step 280B of locating terminal positions the switching of pattern.
Setting according to above gps signal thresholding is judged, can guarantee the opportunity that the indoor and outdoor station-keeping mode switches comparatively exactly, has operability and simplicity, and the station-keeping mode that has improved in user's indoor and outdoor crossing process switches experience.
Yet; If only the thresholding of the gps signal of this artificial setting of foundation judges that the switching of indoor and outdoor station-keeping mode also can bring some problems; The principle of this threshold setting foundation is that gps signal can't be searched star and plays a role when veil is arranged, and in outdoor inlet chamber, gps signal can rapid drawdown; By indoor go out outdoor, can search gps satellite.And in outdoor process, the user passes through bridge, and gps signal decline is judged when reaching the thresholding of gps signal in the time of veils such as trees; The then inside and outside erroneous judgement of switching of locating terminal meeting generating chamber; Erroneous judgement is disconnected and switch to the indoor positioning pattern, cuts out gps signal, walk out the coverage of bridge and number after; Switch back outdoor station-keeping mode again, add gps signal.Based on same reason, in indoor skylight, the place that window etc. are open, locating terminal also might search satellite, occur switching repeatedly by mistake.This gps signal switches the indoor and outdoor map repeatedly by mistake, can cause the instability of locating terminal system itself and the instability of positioning result, also makes positioning result have a part of measuring error.
On this basis, in order more accurately to hold the opportunity that the indoor and outdoor station-keeping mode switches, the gateway that is introduced in map is provided with buffer zone, and is specific as follows:
Step 210: be provided with one and be in indoor buffer zone leading to outdoor gateway, be provided with one and be in outdoor buffer zone leading to indoor gateway;
To this problem; Present embodiment is the legal binding site that passes through of user in the indoor and outdoor; Just map and outdoor map are provided with two buffer zones respectively in the position respective chamber/chambers of gateway; Leading to of indoor map outdoor gateway be provided with one and be in inner buffer zone, leading to of outdoor map indoor gateway be provided with one and be in outside buffer zone.
The buffer length distance, width distance, shape are according to the shape of concrete buildings, and the gateway is big or small, concrete condition setting around this buildings.Its width distance is unsuitable excessive simultaneously, needs fusion location and the indoor fusion locating accuracy setting that cuts out GPS with reference to the outdoor GPS of comprising.For example to merge locating accuracy be 5 meters for the former GPS, LBS, inertial navigation system; The buffer zone of corresponding outside can be made as 5 meters; Behind the indoor correction technique that latter LBS, inertial navigation system location process are correlated with, precision is 3 meters, and the buffer zone of corresponding inside can be made as 3 meters.Generally speaking, the span of the width distance of these two buffer zones can be 3 ~ 5 meters.
Interface with Fig. 3 is illustrated; The left-half of Fig. 3 is the LBS of so-and-so shopping center one deck, the indoor map of inertial navigation system location; Gateway set inside at the mall an internal buffer; This buffer zone has been confirmed width distance according to the concrete precision of this LBS; And because the inner concrete finishing structure of commercial building has produced deformation, and be that GPS merges on the outdoor map of locating with LBS, inertial navigation system at Beijing of Fig. 3 right half part map, on the user's of each macroscopical buildings gateway, also be provided with the external buffer district.Can clearly obtain the two-layer buffer zone setting in this shopping center from Fig. 3.If certain buildings has a plurality of gateways, its corresponding inside and outside buffer zone also has a plurality of.And buffer zone be provided with can be visible also can be to exist but sightless.
Behind the buffer zone of the preset thresholding of searching the star signal and map, judge at first in the location whether this positional information is specific as follows in the buffer zone of map:
Step 220: obtain positional information, judge that current this positional information is whether in buffer zone;
In the present embodiment; If current outdoor, then obtain current location information according to what the GPS location and the fusion of LBS location, inertial navigation system were located, be presented on the outdoor map; If it is current indoor; Then merge the location according to LBS location, inertial navigation system and obtain current location information through relevant indoor correction technique, be presented on the indoor map, this positional information comprises the orientation distance error.Locating terminal is through judge the current buffer zone that whether is positioned at certain short period at interval continuously.Wherein, Because in the follow-up judgement, with the number of satellite thresholding judge with a high credibility in the confidence level of judging with unit interval signal to noise ratio (S/N ratio) decline thresholding, correspondingly; Outdoor in indoor switching; Need all be in the buffer zone of indoor inside with continuous at interval three judgement current locations of certain short period, just judge current location in buffer zone, otherwise then current location be positioned at outside the buffer zone.And indoor in outdoor process, only need judge once that current location is in outdoor external buffer district, can judge current location in buffer zone, otherwise then current location is positioned at outside the buffer zone.
Step 230:, continue to obtain current location information if current location information outside buffer zone, keeps current station-keeping mode;
Locating terminal, that is to say if current location information is positioned at outside the buffer zone through with above-mentioned condition judgment; The inlet of legal building also has certain distance on the outdoor map of user distance; This moment, to give tacit consent to map be latest edition, descends suddenly or search out satellite even gps signal then occurs, reaches the thresholding of gps signal; Its result also must be that mistake is switched; Keep current indoor outdoor station-keeping mode, correspondingly keep in the present locating terminal display room outdoor map constant, continue to follow the tracks of and obtain current position information.
Step 240: if current location information in buffer zone, continues to judge whether to reach the step of the thresholding of searching the star signal;
The locating terminal process is with above-mentioned condition judgment; If current location information is positioned at buffer zone; Basically can judge around its binding site that has been in the indoor and outdoor; Because the positioning error of positional information also need combine number of satellite thresholding and unit interval signal to noise ratio (S/N ratio) decline thresholding among the set GPS, further judge respectively and optimize indoor outdoor, the outdoor indoor switching of arriving of arriving.
Step 250: the star information of searching of obtaining locating terminal;
Owing to need the thresholding of the gps signal of combination setting; Therefore, judge that at locating terminal positional information has been on the basis in the buffer zone, need obtain the gps signal information of locating terminal; Whether reach thresholding according to these gps signal information, confirm the opportunity that indoor and outdoor is switched.
Step 260: judge this and search star information and whether reach the thresholding of searching the star signal;
Step 270: when not reaching this thresholding of searching the star signal, keep current station-keeping mode, continue to obtain current location information;
If not reaching the thresholding explanation active user who searches the star signal only is near the binding site of indoor and outdoor; The intention of not passing through in other words, is being carried out indoor and outdoor and is being passed through; But do not arrive the geographical real binding site of; At this moment locating terminal same keep current indoor outdoor station-keeping mode, correspondingly keep in the present locating terminal display room outdoor map constant, continue to follow the tracks of and obtain current position information.
When reaching this thresholding of searching the star signal, switch station-keeping mode.
Wherein, can be divided into two kinds of situation:
In positional information appears at buffer zone; If gps signal descends suddenly in the unit interval; Reach preset thresholding, can judge in view of the above that then this moment, locating terminal moved towards indoor from outdoor, the GPS of locating terminal, LBS and inertial navigation system merge the location and switch to LBS, inertial navigation system fusion location; Correspondingly outdoor map switches to indoor map, promptly switches to the indoor positioning pattern by outdoor station-keeping mode.
Because buffer zone and measuring accuracy, the gateway is corresponding to be provided with, and the area of itself is very limited; The user is difficult to occur above-mentioned under bridge under this limited condition; Erroneous judgement situation under the trees, positional information arrived buffer zone itself also indicating the user arrived the indoor and outdoor binding site around, in conjunction with reaching the thresholding of searching the star signal; Can judge directly that the terminal has reached the geographical binding site in indoor and outdoor in time, switches to outdoor station-keeping mode the switching of indoor positioning pattern.
In positional information appears at buffer zone; If gps signal search 3 satellites; Reach preset thresholding, can judge in view of the above that then this moment, locating terminal moved towards outdoor from indoor, the LBS of locating terminal, inertial navigation system merge the location and switch to GPS, LBS and inertial navigation system fusion location; Correspondingly indoor map switches to outdoor map, promptly by the indoor positioning mode switch to outdoor station-keeping mode.
Because buffer zone and precision, setting is agreed with in the gateway, and the area of itself is very limited; The user is difficult to occur above-mentioned at window under this limited condition; Erroneous judgement situation under the skylight, positional information arrived buffer zone itself also presetting the user arrived the indoor and outdoor binding site around, in conjunction with reaching the thresholding of searching the star signal; Can judge directly that the terminal has reached the geographical binding site in indoor and outdoor in time, with of the switching of indoor positioning mode switch to outdoor station-keeping mode.
In addition; For some reason---the overcast and rainy adverse weather of black clouds etc. for example; The user by indoor after outdoor; Gps signal possibly can't search the satellite of predetermined number, if at this moment locating terminal judges that current locations all are in the buffer zone of outdoor outside continuous three times with certain short period interval, just can directly the indoor positioning mode switch be arrived outdoor station-keeping mode; Prevent owing to search the situation that can't switch to indoor map less than the indoor map of satellite, improved indoor stability in the outdoor switching judging.The beneficial effect of the method that present embodiment provides is: present embodiment is searched the thresholding of star signal through setting; Outdoor search star location and location, base station, the fusion location of inertial navigation system and the accurate automatic switchover that indoor base station location, inertial navigation system merge the location have been realized; On this basis; The buffer zone setting that further on indoor map and outdoor map, adds facing position information; It is combined with the thresholding of searching the star signal to judge, when having avoided the trueness error in positional information location own, also greatly reduce owing to search the thresholding of star signal itself and set the occurrence frequency that repeats invalid mistake switching that causes.The i.e. buffer zone of searching star signalc threshold and map through combining position information, setting; The dual assurance that makes the indoor and outdoor change action obtain to search the star signal criterion and pass through the positional information benchmark of buffer zone correction; Perfect whole station-keeping mode handover scheme; Make the indoor and outdoor station-keeping mode automatically switch and realized the seamless accurate switching of indoor and outdoor station-keeping mode, improved user's experience.
