Indoor spatial-environment measurement using ultra-wideband positioning system

This paper presents a robust, reliable, and compact three-dimensional (3D) environment visualization system that uses ultra-wideband (UWB) position estimation. This method enables quick and effortless spatial environment measurements with low computation costs. The UWB location estimation uses wireless communication to provide high flexibility and accuracy in measurements. We developed a prototype system that combines UWB and environmental sensors to collect temperature, luminance, and location data in a real space. The prototype is compact and collects environmental information efficiently. Furthermore, the spatial distribution of the collected ambient data of an object can be visualized in 3D using it. The results show that the prototype system with UWB is suitable for measuring indoor environmental data.
