Beacons

During mapping, the mobile mapping system captures signals from Bluetooth beacons. During post-processing, this information is written to bluetooth_beacon.csv in the form of tupels containing the following information:

• The timestamp (in seconds) when the signal was received

• The position of the mobile mapping system x, y, z (in meters) relative to the Dataset's origin

• The orientation of the mobile mapping system relative to the dataset's origin (as a quaternion w, x, y, z)

• The intensity of the signal received in decibel milliwatts

• Data sent by the beacon, starting from the last four bytes of the iBeacon prefix.
