无基站多目标网络定位可视化实现

Implementation of Visualization for Multi-Target Localization

为解决无基站多目标网络定位可视化中相对位置呈现问题,提出了交互式的多目标地图配准可视化方案,在对多目标网络建模并使用多维尺度变换进行相对位置求解的基础上,使用交互式的平移、旋转、缩放、镜像操作将多目标相对位置作为整体与地图进行配准,建立相对坐标与绝对经纬度之间的映射,并使用UWB(Ultra Wide Band)技术在室内场景进行了多目标场景的可视化实现。实测结果表明,交互式配准的方式简单易行,12个节点的多目标定位可在秒级时间内完成。

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.
