The geo information of scanned objects can be used as a good approximation for the position of the user. Therefore two scenarios were implemented:
The geo information of an object gets used automatically if exactly one single ob-ject is found through scanning. If more objects are found, their geo information doesn´t get used. Scanning includes ID-Markers, OCR, QR-Codes, Barcodes, RFID and Markerless Tracking.
If QR-Codes configured as LLA Markers are scanned in the POI-View, their position is overtaken as the device position.
LLA markers
LLA markers basically are QR codes with location data encoded into them - which can be used for positioning when they are scanned. LLA-Markers are configured as follows (Note that the altitude is described as the elevation from ground in meters):
<LLA>Latitude;Longitude;Altitude</LLA>
</UBIK>
Characteristics
- Provides position in world coordinates.
- The error in position estimation depends on the scanning distance and proper configuration of the geo object.
