Abstract

In indoor visible light positioning systems, indoor reflections in different room size will cause different impact on positioning accuracy. In this work, we investigate the RSS-based positioning errors with different room size. Results show that when the room size increases, positioning accuracy is becoming higher. When room size reaches 15m∗15m∗3m, the maximum positioning error due to non-line-of-sight (NLOS) is only 1 mm worse than that for line-of-sight (LOS) case. Thus, if room size exceeds this value, we can ignore NLOS effect. We also considered the effect of LED half power angle and receiver field-of-view changes on maximum positioning error. Results show that the former has greater impact on positioning.
