摘要
为提高非合作室内环境下超宽带组网定位能力,采用无中心定位算法理论对超宽带测距输出距离信息进行解算分析,得到相对定位结果,并将定位结果与光电标定系统结果进行实测对比,对精度进行评估。结果表明,相比传统超宽带定位模式,利用超宽带测距和无中心定位算法相结合的形式,能够实现无中心定位以及各节点之间的相对位置解算,最终确定各节点之间的相对位置。超宽带测距和无中心定位算法相结合,在相对定位方面具有良好的稳定性和精确度,可以广泛应用于室内室外多种场景。
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.
