Abstract: Embodiments herein disclose a pose detection device for a movable body and a location-based supplemental service providing system. The pose detection device includes a first polarization unit and a second polarization unit positioned to have transmission axis difference values different from each other, wherein the first polarization unit and the second polarization unit receiving light emitted from a polarized light source located beyond and apart from the first polarization unit and the second polarization unit. Further, the pose detection device includes a first illuminometer measures positioned below the first polarization unit and a second illuminometer positioned below the second polarization unit.

Abstract: Provided are a system and method of recognizing an indoor location of a moving object. A recognition device includes an illumination unit including a plurality of illumination modules respectively having different predetermined light receiving characteristics, each of the illumination modules receiving polarized light emitted from at least one lighting device according to one of the predetermined light receiving characteristics and measuring an illumination value; and an analysis unit configured to calculate a light source polarization axis angle of the at least one lighting device using a predetermined linear polarization rule and the illumination value measured by each illumination module, the at least one lighting device emitting light received by the illumination unit.

Abstract: Accordingly the embodiment herein provides a device for recognizing a 3D posture and a location of a movable body. The device includes: a plurality of polarization modules individually attached to a plurality of surfaces of a 3D figure; a plurality of illumination modules individually corresponding to the polarization modules and generating and outputting illumination value information in which polarized light emitted from a polarization light source penetrates the corresponding polarization module to be received; and an interpretation unit generating posture information and location information of the movable body by using the illumination value information received from the illumination modules corresponding to the polarization modules attached to at least three considered target surfaces.
