Indoor Positioning By Led Visible Light Communication And Image Sensors

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.

Indoor positioning by led visible light communication and image sensors.

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

Advances in visible light communication vlc technology and the ubiquity of illumination facility have led to a growing interest in vlc based indoor positioning. Vlc systems take advantage of the fast modulation of the visible light that light emitting diodes leds enable. Indoor positioning systems based on vlc can be used in places such as hospitals eldercare homes warehouses and large open offices to locate people and control indoor robotic vehicles. We propose an algorithm for high precision indoor positioning using lighting leds vlc and image sensors.

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. As is shown in fig. 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. Inspired by the quick response qr code design the four corner leds on the array are defined as flag leds and three of them.

High power white leds are expected to replace the existing lighting technologies in near future which are also suggested for visible light communication vlc. High precision indoor positioning using lighting led and image sensor abstract. Indoor white light leds are located at. There is wireless network that for data transmission uses visible light and does not use intensity modulation of optical sources.
