Abstract
(EN)
A method of determining data of a fingerprint map includes: obtaining visible light communication signals at a mobile device (104); determining yaw of the mobile device (104) using the visible light communication signals; obtaining roll and pitch of the mobile device (104); determining a transformation of a mobile-device coordinate system (124, 126) to a reference coordinate system (107) using the roll, pitch, and yaw; obtaining first indications of vector components of a field at a location of the mobile device (104); and sending, to a server (718), the first indications and the transformation; or determining second indications of vector components of the field using the first indications and the transformation, the second indications being indicative of vector components at the location of the mobile device (104) in the reference coordinate system (107), and sending, to the server (718), the second indications; or sending the first indications to the server (718), and determining and sending the second indications to the server (718).
