针对VIRE算法定位精度低的不足,提出一种改进算法,其中包括非线性插值算法、动态阈值的设定以及模糊地图的标签自校正.构建基于参考标签的室内定位系统,并开发界面软件.实验结果表明,VIRE改进算法能在不增加参考标签数目的情况下,提高定位精确度,改善恶劣环境定位结果的稳定性.%Aiming at the shortage that the positioning accuracy of the VIRE algorithm is low, the improvement algorithm is introduced. It includes the nonlinear interpolation algorithm, and the dynamic threshold setting as well as the self-correcting of tags in the dim map. The indoor positioning system based on reference tag is constructed. Then the interface software is built. Experimental results show that the improvement VIRE algorithm improves the positioning accuracy and the positioning stability in complex environments significantly without adding reference tag numbers.
