An accurate and reliable Indoor Positioning System (IPS) applicable to most indoor scenarios has been sought for many years. The number of technologies, techniques, and approaches in general used in IPS proposals is remarkable. Such diversity, coupled with the lack of strict and verifiable evaluations, leads to difficulties for appreciating the true value of most proposals. This paper provides a meta-review that performed a comprehensive compilation of 62 survey papers in the area of indoor positioning. The paper provides the reader with an introduction to IPS and the different technologies, techniques, and some methods commonly employed. The introduction is supported by consensus found in the selected surveys and referenced using them. Thus, the meta-review allows the reader to inspect the IPS current state at a glance and serve as a guide for the reader to easily find further details on each technology used in IPS. The analyses of the meta-review contributed with insights on the abundance and academic significance of published IPS proposals using the criterion of the number of citations. Moreover, 75 works are identified as relevant works in the research topic from a selection of about 4000 works cited in the analyzed surveys.

“…In table 1, a comparison between our works and previous experimental works of single LED VLP systems is presented. There are also other single LED VLP systems applying multiple tilted optical receivers [6], [47], but they require the targeted LED located in the field-of-view (FOV) of at least three tilted receivers. To keep the independence among different receivers, the tilted angle among those receivers can't be too small.…”

In this paper, we developed a visible light positioning (VLP) system using a camera and lowcost inertial measurement units (IMUs). Applying computer vision and sensor fusion techniques, our VLP system is able to estimate the angle of arrival (AoA) and the distance from a landmark to a mobile device. Due to the complementary nature between IMUs and cameras, we are able to improve the performance of VLP systems by applying sensor fusion. Currently, most optical positioning systems require at least two line-of-sight (LOS) links, so the coverage is not always satisfactory. Using a single round light-emitting diode (LED) panel or two coplanar black thick rings as the landmark, our VLP system only needs one LOS link to estimate the orientation and position of the mobile device. By activating inertial navigation, our VLP system is able to perform localization even if the landmark is temporarily blocked by obstacles. We derived approximated upper bounds of the angular errors and applied visual-inertial sensor fusion in estimating the Euler angles of the mobile device. Since the weights of sensor fusion are determined by upper bounds, the expected maximum errors are minimized in our positioning system. In our field experiments, the positioning system has an average positioning error of 0.18m with an effective positioning range of 7m. Compared to similar types of positioning systems, our system has significant improvements in positioning range without sacrificing positioning accuracy.

“…A variety of techniques like On-Off Keying (OOK) or Square Wave Modulation [40], Orthogonal Frequency Division Multiple Access (OFDMA) [41], discrete tone multiplexing based on Intensity Modulation Direct Detection (IM/DD) [28], Optical Code Division Multiple Access (OCDMA) [42] have been utilized. It should be pointed out that simulation based studies have shown that by employing smartphones [43], fusion of multiple sensors [22], and tags containing multiple photo-sensors [44], it might be possible to localize a target while employing just a single visible luminaire. Multiple photodiode-based localization systems have also been reported in [21], [45]- [47].…”

Indoor Visible Light Positioning Using Spring-Relaxation Technique in Real-World Setting

et al. 2019

GPS has limitations in indoor applications. Consequently, other indoor localization techniques and systems are active areas of research. Visible Light Positioning (VLP) is a promising option, especially given the growing popularity of LED-based lighting and the expected adoption of the forthcoming Visible Light Communication (VLC). This paper reports a novel VLP technique. The developed technique uses received signal strength for ranging. It is followed by the iterative estimation of a location using spring relaxation. The performance of the proposed technique was experimentally evaluated in indoor settings and benchmarked against the lateration-and fingerprint-based localization approaches in multiple scenarios. The obtained results demonstrate that the proposed VLP approach offers an opportunity to outperform the existing techniques in terms of localization accuracy and precision. INDEX TERMS Indoor localization, visible light positioning (VLP), indoor positioning system (IPS), received signal strength (RSS).
