Embodiment
Below in conjunction with Figure of description, specific implementation of the present invention is made a detailed description.
Fig. 1 is the process flow diagram of the distance-finding method according to the embodiment of the present invention.As shown in Figure 1, this distance-finding method mainly comprises following process:
Step S101: based on the GPS positioning function of mobile terminal, determines the coordinate information of the coordinate information of the primary importance residing for above-mentioned mobile terminal and the second place residing for above-mentioned mobile terminal;
Step S103: according to the coordinate information of above-mentioned primary importance and the coordinate information of said second position, obtain the distance between above-mentioned primary importance and said second position.
In correlation technique, user may not carry with tape measure, tape measure, and the specialty such as ultrasonic range finder and infrared range-measurement system range finding article, therefore cannot accomplish to find range whenever and wherever possible.The range finding implementation method of carrying out finding range in conjunction with mobile phone is all range-measuring circuit (such as, laser ranging circuit) is integrated into interior of mobile phone realize, and therefore needs to carry out Cell Phone Design specially, thus adds complexity and the cost of mobile phone.In the method shown in Fig. 1, based on the GPS positioning function of mobile terminal, by software simulating range observation, without the need to range-measuring circuit is integrated into interior of mobile phone, thus reduce complexity and the cost of mobile phone.
Wherein, above-mentioned mobile terminal can be mobile phone, iPad, digital camera etc.Above-mentioned coordinate information can be latitude and longitude value.
Preferably, before execution above-mentioned steps S101, following process can also be comprised: based on above-mentioned GPS positioning function, export the coordinate information of the position residing for above-mentioned mobile terminal in real time; Response user chooses operational order, determines above-mentioned primary importance and said second position.
In preferred implementation process, after user opens distance measurement function, based on the GPS positioning function of mobile terminal, can output mobile terminal is current in real time coordinate position, such as, longitude 112 ° 13.12 ', 25 ° 11.33 ', latitude.When user determines the starting point that will measure, perform in this position and choose operation, such as, clicking operation, then mobile terminal is according to the operational order of user, determines that current location is starting point (i.e. above-mentioned primary importance); When user determines the terminating point that will measure, perform in this position and choose operation, such as, clicking operation, then mobile terminal is according to the operational order of user, determines that current location is terminating point (i.e. said second position).
Such as, can by the DDMS view of Eclipse, the change in location of analog machine, after changing longitude and latitude, clicks send, then working procedure, and in the application, the dynamic position obtaining mobile terminal, then shows current positional information.
Obtain positional information and be divided into three steps:
1. add-on system authority, supports the access to LBS hardware
<uses-permission android:name＝"android.permission.ACCESS_FINE_LOCATION">
</uses-permission>
2. obtain the LocationManager object of system service
LocationManager loctionManager；
String contextService＝Context.LOCATION_SERVICE；
// by system service, obtain LocationManager object
loctionManager＝(LocationManager)getSystemService(contextService)；
3. obtain location provider, by location provider, obtain positional information, concrete location provider can be specified, also can provide a standard set, allow system according to the optimal location provider of matches criteria, positional information provides it to provide by position.
A. position (specifying concrete location provider) is obtained by GPS location provider
String provider＝LocationManager.GPS_PROVIDER；
Location location＝loctionManager.getLastKnownLocation(provider)；
B. use standard set, allow system automatically select available optimum position provider, position is provided
Criteria criteria＝new Criteria()；
Criteria.setAccuracy (Criteria.ACCURACY_FINE); // high precision
Criteria.setAltitudeRequired (false); // do not require height above sea level
Criteria.setBearingRequired (false); // do not require orientation
Criteria.setCostAllowed (true); // allow cost
Criteria.setPowerRequirement (Criteria.POWER_LOW); // low-power consumption
// from available location provider, mate the best provider of above standard
String provider＝loctionManager.getBestProvider(criteria,true)；
// obtain the last position changed
Location location＝loctionManager.getLastKnownLocation(provider)；
The change of monitoring position
// monitoring position changes, and 2 seconds once, distance more than 10 meters
loctionManager.requestLocationUpdates(provider,2000,10,locationListener)；
// position audiomonitor
private final LocationListener locationListener＝new LocationListener(){
@Override
public void onStatusChanged(String provider,int status,Bundle extras){
}
@Override
public void onProviderEnabled(String provider){
}
@Override
public void onProviderDisabled(String provider){
}
// trigger when change in location
@Override
public void onLocationChanged(Location location){
// use new location to upgrade TextView display
updateWithNewLocation(location)；
}
}；
By changing position longitude and latitude, program can upgrade the positional information of TextView display automatically.
In step s 103, distance L between above-mentioned primary importance and said second position can be obtained by following formula:
L=[(longitude coordinate of the longitude coordinate-second place of primary importance) ^2 ﹢ (latitude coordinate of the latitude coordinate-second place of primary importance) ^2] ^ (1/2)
Further illustrate below in conjunction with example.
First, degree of carrying out is needed to divide conversion to the coordinate of the starting point got and the coordinate of terminating point:
By degree point unit data degree of being converted to unit data: degree=degree+point/60
Such as:
Starting point longitude=116 ° 20.12 '
Starting point latitude=39 ° 12.34 '
Then longitude degree of being converted to unit data, longitude=116+20.12/60=116.33533 °
Then latitude degree of being converted to unit data, latitude=39+12.34/60=39.20567 °
NTU longitude=116.33533 × 100000=11633533 (NTU)
NTU latitude=39.20567 × 100000=3920567 (NTU)
Terminating point longitude=116 ° 20.7 '
Terminating point latitude=39 ° 12.275 '
Then longitude degree of being converted to unit data, longitude=116+20.7/60=116.34500 °
Then latitude degree of being converted to unit data, latitude=39+12.275/60=39.20458 °
NTU longitude=116.34500 × 100000=11634500 (NTU)
NTU latitude=39.20458 × 100000=3920458 (NTU)
Then can calculate the distance between starting point and ending point according to the latitude and longitude coordinates of starting point and the latitude and longitude coordinates of terminating point:
L＝[(11633533－11634500)^2﹢(3920567－3920458)^2]^(1/2)
＝(935089+11881)^(1/2)＝973.123836(m)
