摘要
为了解决在室内环境中利用三边定位技术定位精度不高,以及基于质心定位改进三边定位算法后参考点难以确定在待测点外侧的问题,提出一种利用Eddystone-TLM对三边定位算法进行改进。首先利用Eddystone框架的TLM优化质心定位算法;其次通过优化后的质心定位算法解决三边定位算法已知的不足;最终实现定位精度的提高。实验结果表明,该算法改善了室内定位的精准性,可及时准确地获取目标终端的位置数据,有效保证了室内定位与其他领域之间定位数据的互联互通。
An improved trilateral localization algorithm based on Eddystone⁃TLM is proposed to solve the low accuracy of positioning with the trilateral localization technology in the indoor environment and the problem that it is difficult to determine the reference point outside the point to be measured by means of the improved trilateral localization algorithm based on the centroid localization.First,the TLM of the Eddystone frame is used to optimize the centroid localization algorithm,by which the known deficiency of the trilateral localization algorithm is solved to realize the improvement of the localization accuracy.The experimental results show that this algorithm can improve the accuracy of the indoor localization,and obtain the localization data of the target terminal timely and accurately,which effectively ensures the data interconnection between indoor localization and other field localization.
