Deep Learning-Based Robust Visible Light Positioning for High-Speed Vehicles

چکیده
Robustness is a key factor for real-time positioning and navigation, especially high-speed vehicles. While visible light (VLP) based on LED illumination image sensors widely studied, most of the VLP systems still suffer from high latency blurs caused by movements. In this paper, robust system vehicles proposed deep learning data-driven approach. The can significantly increase success rate decoding VLP-LED user identifications (UID) blurred images reduce computational detecting extracting stripe regions captured images. Experimental results show that UID using BN-CNN model could be higher than 98% when traditional Zbar-based decoder falls to 0, while time decreased 9.19 ms supported moving speed our scheme achieve 38.5 km/h. Therefore, enhance robustness against movement guarantee response navigation

Indoor Positioning in High Speed OFDM Visible Light Communications
Visible Light Communication (VLC) technology using light emitting diodes (LEDs) has been gaining increasing attention in recent years as it is appealing for a wide range of applications such as indoor positioning. Orthogonal frequency division multiplexing (OFDM) has been applied to indoor wireless optical communications in order to mitigate the effect of multipath distortion of the optical cha...
متن کاملA Visible Light Based Indoor Positioning System
In this paper, we propose a novel indoor localization scheme, Lightitude, by exploiting ubiquitous visible lights, which are necessarily and densely deployed in almost all indoor environments. We unveil two phenomena of lights available for positioning: 1) the light strength varies according to different light sources, which can be easily detected by light sensors embedded in COTS devices (e.g....
متن کاملEpsilon: A Visible Light Based Positioning System
Exploiting the increasingly wide use of Light-emitting Diode (LED) lighting, in this paper, we study the problem of using visible LED lights for accurate localization. The basic idea is to leverage the existing lighting infrastructure and apply trilateration to localize any devices with light sensing capability (e.g., a smartphone), using LED lamps as anchors. Through the design of Epsilon, we ...
متن کاملHigh - speed visible light communication system based on SiPM
Silicon Photomultiplier (SiPM) is a photodetector with very high sensitivity, fast response and good performance in oversaturation conditions. When SiPM faces incident optical radiation (sometimes imperceptible for other photodetectors) is able to detect very small variations of light. In this work, we present a SiPM-based optical receiver ables to discriminate small light signals from backgrou...
متن کاملApplication of robust, high-accuracy positioning for autonomous ground vehicles
In this paper we review the need for robust, high-accuracy positioning for path guidance in the presence of large structures (such as buildings and trees) and for the integration of sensor data. Such capability is necessary in many applications that require precision over vast areas of operation. We find that unless integrated tightly, combined INS/GPS systems diverge significantly when line of...
