DarkVLP: “Lights-Off” Visible-Light Positioning
IEEE Internet of Things Journal, 2022Visible Light Positioning (VLP) has been considered as a promising indoor positioning technology due to its high precision and low cost. However, current visible light positioning techniques are greatly limited by the assumption that lights have to be turned on to emit shining light beams, which is not applicable to scenarios that do not need the ...

Signature Codes in Visible Light Positioning
IEEE Wireless Communications, 2021With the explosive development of the Internet of Things (IoT), massive equipments are involved in the indoor environment with the demand of precise localization to provide intelligent interconnection. The visible light positioning (VLP) system, with the light emitting diode (LED) and the photo-diode (PD) or image sensor as the transceiver, has ...

Passive Positioning using Visible Light Systems
Optical Fiber Communication Conference (OFC) 2021, 2021Passive indoor visible light localization detects changes in illumination patterns in a room to infer the position of a user. We present analytical bounds on positioning error of an object in an indoor scenario and use deep learning to estimate positioning in realistic scenarios.

Indoor Position Tracking Using Visible Light
2015 IEEE 82nd Vehicular Technology Conference (VTC2015-Fall), 2015The demand for a highly accurate indoor positioning system is rapidly increasing. In the last few years, several positioning systems based on visible light communications that achieve good positioning accuracy have been proposed. However, these systems are based on assumptions such as complete knowledge of the height of the receiver, exact alignment of

Polarization-Based Visible Light Positioning
IEEE Transactions on Mobile Computing, 2019Visible Light Positioning (VLP) provides a promising means to achieve indoor localization with sub-meter accuracy. We observe that the Visible Light Communication (VLC) methods in existing VLP systems rely on intensity-based modulation, and thus they require a high pulse rate to prevent flickering.

Transmitter Position Error Impact On Camera Based Visible Light Positioning Systems
2022 4th West Asian Symposium on Optical and Millimeter-wave Wireless Communications (WASOWC), 2022This paper analyses the impact of fixture measure-ment uncertainty on the position estimation error in a camera-based Visible Light Positioning (VLP) system. The system is comprised of four light fixtures, placed at a height of 2.7 m, and a camera, placed across a 1m x 1m grid on the floor.

Visible light positioning: Automotive use case
2010 IEEE Vehicular Networking Conference, 2010The use of positioning sensors on automobiles is becoming increasingly common with the desire to facilitate utility and traffic safety by giving the driver information on the automobiles position relative to the surroundings. In this paper we introduce a positioning technique based upon automobile LED lighting — either taillights or headlights — that ...

Indoor Positioning Using Visible LED Lights
ACM Computing Surveys, 2015Visible light LEDs, due to their numerous advantages, are expected to become the dominant indoor lighting technology. These lights can also be switched ON/OFF at high frequency, enabling their additional use for wireless communication and indoor positioning.
