中文摘要:
      為提高非合作室內環境下超寬帶組網定位能力,采用無中心定位算法理論對超寬帶測距輸出距離信息進行解算分析,得到相對定位結果,并將定位結果與光電標定系統結果進行實測對比,對精度進行評估。結果表明,相比傳統超寬帶定位模式,利用超寬帶測距和無中心定位算法相結合的形式,能夠實現無中心定位以及各節點之間的相對位置解算,最終確定各節點之間的相對位置。超寬帶測距和無中心定位算法相結合,在相對定位方面具有良好的穩定性和精確度,可以廣泛應用于室內室外多種場景。
英文摘要:
      In order to improve the positioning ability of ultra wideband network in non-cooperative indoor environment, the theory of centreless positioning algorithm was used to solve and analyze the output distance information of ultra-wideband ranging, and the relative positioning results were obtained. The positioning results of the system were compared with the results of the photoelectric calibration system, and the accuracy was evaluated. The results show that, compared with the traditional ultra-wideband positioning model, the combination of ultra-wideband ranging and centreless positioning algorithm can realize the centreless positioning and the relative positions among nodes, and finally determine the relative positions among nodes. The combination of UWB ranging and centreless positioning algorithm has good stability and accuracy in relative positioning, and can be widely used in various indoor and outdoor scenes.
