“…When the receiving end approaches a certain LED lamp, it will receive the corresponding ID, allocate it to the required position through the ID, and estimate the position as the location of the receiving end. (12)(13)(14)(15) In the proximity method, spaces in the illuminated area of the same LED are considered as the same position, and the accuracy will be limited by the light density, which can be used in scenarios with lower accuracy requirements. Thus, in indoor parking lots, considering the vehicle's speed and the distribution density of LED lights, the proximity method can be used to meet the user's needs for indoor parking positioning.…”

While visible light communication (VLC) has become the candidate for the wireless technology of the 21st century due to its inherent advantages, VLC based positioning also has a great chance of becoming the standard approach to positioning. Within the last few years, many studies on VLC based positioning have been published, but there are not many survey works in this field. In this paper, an in-depth survey of VLC based positioning systems is provided. More than 100 papers ranging from pioneering papers to the state-of-the-art in the field were collected and classified based on the positioning algorithms, the types of receivers, and the multiplexing techniques. In addition, current issues and research trends in VLC based positioning are discussed.

“…It can also be used to provide location-aware services, such as antique information in museums or item prices in shopping malls. One simple VLP scheme is based on visible light identifier (ID) [9], in which unique ID is emitted by different lamps. However, the accuracy is limited by the lighting zone.…”

We put forward and experimentally demonstrate a second order machinelearning (ML) based visible-light-positioning (VLP) system using simple linear interpolation algorithm to reduce the training samples required in the ML algorithm. Algorithms of the second order regression ML model using 2,430 training samples; and using the reduced training samples of 570 with and without the proposed linear interpolation are compared and discussed. We can observe that the positioning accuracy of using training samples of 570 with the proposed interpolation can have similar performance when compared with using 2,430 training samples. The training samples are reduced by ∼76.5%. Here, off-the-shelf LED lamps and low bandwidth electrical and optical components are employed; and the system is cost-effective. Good quality on-off keying (OOK) identifier (ID) signals are retrieved after frequency down-conversion from 20 kHz, 40 kHz and 60 kHz without and with optical background noises respectively.
