摘要
针对节点不均匀导致的Wi-Fi三边定位算法精度较低的问题,提出了基于质心的改良Wi-Fi三边定位算法。该算法通过计算相交圆的公共区域所组成的质心来提高对待测点位置估算的精确度,然后通过数据图表分析,证明基于质心改良后的Wi-Fi三边定位算法的确比原三边定位算法定位精确度更高。
As for the low precision of the Wi-Fi trilateral localization algorithm caused by the uneven distribution of nodes,the paper proposes a new Wi-Fi trilateral localization algorithm based on centroid.The algorithm effectively improves the location estimation accuracy of the measuring points by calculating the centroid of the overlapping areas of intersecting circles.The results of data analysis and chart analysis prove that the improved Wi-Fi trilateral localization algorithm based on centroid actually provides higher precision than the original trilateral localization algorithm.
