Abstract: In order to visualize relative positions for multi-target network without base stations, an interactive multi-target map matching visualization scheme is proposed. Localization modeling for multi-target network, multidimensional scaling transformation for solving the relative position are adopted first, then with the help of interactive translation, rotation, scaling, and mirroring operations the target positions of nodes as a whole are matched with local map, thus the mapping between relative coordinates, absolute latitude and longitude is established, and the multi-target scene is realized in indoor environment with UWB(Ultra Wide Band ). The experimental results show that the interactive matching method is simple and feasible, and the interactive response time is less than 100 ms, which has a good user experience.

Key words: indoor localization, multi-target localization, visualization, ultra wide band(UWB)
