SYSTEM AND METHOD FOR OBTAINING RELATIVE LOCATION OF ANCHOR-FREE UWB-BASED NODE

There is provided a method performed by a system for obtaining a relative location of an anchor-free UWB-based node. The method includes obtaining relative distances between a plurality of nodes based on UWB sensor values between the nodes, constructing a relative coordinate system having a center n...

Zusammenfassung:	There is provided a method performed by a system for obtaining a relative location of an anchor-free UWB-based node. The method includes obtaining relative distances between a plurality of nodes based on UWB sensor values between the nodes, constructing a relative coordinate system having a center node of the plurality of nodes as a base, and calculating coordinate values of other nodes in the relative coordinate system. The constructing of the relative coordinate system having the center node of the plurality of nodes as a base includes constructing the relative coordinate system based on a relative distance between the center node and another node and absolute values of y axis values.
