Our High Precision 3D Indoor Positioning solution provides high precision localization in indoor environments based on Visible Light Communications (VLC). It is based on Optical Camera Communication (OCC) and uses LED landmarks and a CMOS camera (e.g. a common smartphone camera). It operates well even when the receiver is not directly under light sources. Besides, it does not require additional hardware and provides orientation in yaw, roll and pitch. This technology has a wide range of applications in retail, industry and entertainment domains.
