Design of OCC Indoor Positioning System Based on Flat Panel Light and Angle Sensor Assistance

Abstract

Visible light positioning (VLP) technology is a classic application of visible light communication (VLC), which inherits the advantages of VLC and applies it to the field of positioning. LED (light-emitting diode) is a type of light source. Because of its high brightness, aesthetically pleasing characteristics, and ease of installation, it is used in a variety of indoor lighting applications. However, most of the current VLP technology is still in the laboratory simulation stage and cannot be used in industry or life on a large scale due to various reasons, such as accuracy and cost. Because of the large size of LED flat panel lamps, there are almost no VLP applications with LED flat panel lamps as the emitting light source. Therefore, this paper proposes a VLP technology combining LED flat panel light and a barcode, with a single flat panel light at the transmitting end and a smartphone with a camera at the receiving end, to achieve fuzzy positioning. The paper further uses the angle sensor to assist in designing the “pseudo-two-light positioning” algorithm and selects 16 test points for experiments, and the average positioning error can reach a minimum of 6.5023 cm, achieving centimeter-level positioning accuracy requirements.

Design and Implementation of a Hybrid Optical Camera Communication System for Indoor Applications

“…In [ 12 ], drone-to-vehicle communication was proposed using rolling shutter camera, which achieved a data rate of 3.6 kbit/s with a free-space transmission distance of 23 m. High-speed optical camera V2V communications also proposed in [ 13 ] provide a data rate of up to 3.456 kbps by using RaspiCam. An OCC indoor positioning system based on flat panel light and angle sensor assistance was also proposed in [ 14 ], which can reach the average positioning error of 6.5023 cm. An optical spatial localization algorithm achieved an error of 0.1 m at 3 m distance in [ 15 ].…”

“…Nevertheless, the OCC system is preferable for applications requiring environmental mobility and long-range usage. The OCC system can be used for vehicle-to-vehicle applications [6,7], indoor localization [8,9], and Internet of Things applications [10][11][12]. The orthogonal frequency-division multiplexing (OFDM) technique is utilized to digitally encode data across numerous carrier frequencies.…”

“…The system achieves desirable performances in terms of the modulation transfer function (MTF), distortion, and aberration correction, meeting the requirements for each optical element. Reference [8] presents a cost-effective visible light positioning (VLP) system for indoor positioning, combining LED flat panel lights and barcodes. The proposed "pseudo-two-light positioning" algorithm, assisted by angle sensors, achieves centimeterlevel positioning accuracy.…”
