Paper Abstract

We propose a Visible light positioning (VLP) system which can satisfy the requirements in the places where monitors are required to grasp the location of multiple people or vehicles, such as unmanned supermarkets, warehouses, factories, and other large buildings with safety issues. Which means when the security cameras capturing images, the coordinates of the objects can be obtained and displayed at the same time. This novel Multiple Input Multiple Output (MIMO) VLP system which can monitor multiple objects at the same time provides accurate and high-speed multiple objects indoor positioning based on the Space Division Multiple (SDM), Wavelength Division Multiplexing (WDM) and the under-sampled phase shift ON-OFF keying (UPSOOK). The experimental results show that the proposed system achieves accuracy of 10cm with the range of tilting angle degree is 0° to 45°. The result means the system does well in robustness and accuracy.
