Indoor Positioning By Led Visible Light Communication And Image Sensors

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.

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. Advances in visible light communication vlc technology and the ubiquity of illumination facility have led to a growing interest in vlc based indoor positioning. 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. High precision indoor positioning using lighting led and image sensor abstract. Indoor white light leds are located at. 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.

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. 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. Vlc systems take advantage of the fast modulation of the visible light that light emitting diodes leds enable. We propose an algorithm for high precision indoor positioning using lighting leds vlc and image sensors.

We proposed an algorithm for high. 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. There is wireless network that for data transmission uses visible light and does not use intensity modulation of optical sources. As is shown in fig.
