Indoor Positioning By Led Visible Light Communication And Image Sensors

High power white leds are expected to replace the existing lighting technologies in near future which are also suggested for visible light communication vlc.

Indoor positioning by led visible light communication and image sensors.

Advances in visible light communication vlc technology and the ubiquity of illumination facility have led to a growing interest in vlc based indoor positioning. A quick detection algorithm based on the novel designed led array and the connected component labeling technique is proposed and applied in image sensor based visible light communication is vlc system. We propose an algorithm for high precision indoor positioning using lighting leds vlc and image sensors. Indoor white light leds are located at.

Recently visible light communication vlc has been widely used in indoor positioning which has such advantages as cost saving environmentally friendly anti radio frequency interference anti rf interference and so on. We proposed an algorithm for high. Indoor positioning by led visible light communication and image sensors high power white leds are expected to replace the existing lighting technologies in near future which are also suggested for visible light communication vlc. Numerous techniques have been.

In this paper we propose a higher accuracy indoor positioning algorithm using a stereo image sensor and white light leds by the visible light communication. Visible light communication vlc based on solid state lighting ssl is a promising option either to supplement or to substitute existing radio frequency rf wireless communication in indoor environments. High precision indoor positioning using lighting led and image sensor abstract. As is shown in fig.

1 the working principle of complementary metal oxide semiconductor cmos image sensor is called rolling shutter mechanism which is utilized to realize led id recognition by visible light positioning vlp. High power white leds are expected to replace the existing lighting technologies in near future which are also suggested for visible light communication vlc. There is wireless network that for data transmission uses visible light and does not use intensity modulation of optical sources. Vlc systems take advantage of the fast modulation of the visible light that light emitting diodes leds enable.
