Positioning-Aided Scheme for Image Sensor Communication using Single-View Geometry

Abstract

In this study, we investigate a positioning-aided scheme using computer vision techniques for image sensor communication (ISC), generally referred to as a visible light communication (VLC) system that utilizes an image sensor (camera). The image sensor in ISC is frequently used as a typical receiver because it has the ability to measure light intensity and distinguish multiple light sources. Additionally, thanks to its ability to detect the angle of arrival of light, the image sensor can estimate its own position using computer vision techniques. The positioning accuracy of ISC is reported to be in sub-meter levels that render visible light positioning (VLP). VLP is one of the most excellent positioning applications in indoor settings as global positioning system cannot provide satisfying indoor positioning services. To apply this significant positioning performance of VLP to our visible light system, we propose a positioning-aided scheme for ISC using computer vision techniques here. In addition, we evaluate the demodulation performance and positioning accuracy of our proposed scheme.
