| Summary: | A great deal of research has been devoted to studying indoor localization schemes for the development of location-based services. This study investigated an indoor localization system, including subsystems of nonline-of-sight (NLOS) image-sensor-based visible light communications (IS-VLCs) and the proposed <inline-formula> <tex-math notation="LaTeX">$K$</tex-math></inline-formula>-pairwise light-emitting diode (LED) image-sensor-based visible light positioning (IS-VLP), in a unified lighting environment. A smartphone received multiple LED identifiers through the designed NLOS IS-VLC and successfully performed the proposed <inline-formula><tex-math notation="LaTeX"> $K$</tex-math></inline-formula>-pairwise LED IS-VLP with <inline-formula><tex-math notation="LaTeX">$K = 3$</tex-math> </inline-formula> to achieve localization, with maximum localization errors of 2.92 and 3.54 cm being obtained for ceiling heights of 100 and 150 cm, respectively. |
