针对室内位置指纹定位技术存在的离线阶段工作量大、定位精度有限、顽健性较差的缺点,提出了一种基于线性内插法改进的指纹定位匹配算法。与传统位置指纹定位技术相比,该算法不仅降低了整体工作量,而且降低了多径效应造成的不利影响。最后搭建实验场景对该算法定位性能进行测试。实验数据显示,该算法与WKNN法相比,平均定位精度大约提高了34.25%,绝大部分待测点的定位误差在0.4 m 以内,验证了所提算法在定位精度、顽健性和适应环境变化方面的优势。
Aiming at the shortcomings of heavy workload in the off-line phase
limited positioning accuracy and poor robustness of indoor location fingerprint positioning technology
an improved fingerprint matching algorithm based on linear interpolation was proposed.Compared with the traditional location fingerprint positioning technology
it reduced the overall workload as well as the bad effects caused by muti-path effect.At last
a lab scene was set up to test the positioning performance of this algorithm.It is shown by the test that the average positioning accuracy of this algorithm has been improved by 34.25% compared with that of WKNN method
and the positioning accuracy error ratio of most points to be test is within 0.4 m
the positioning accuracy
robustness and adaptability in environment change were demonstrated.
