摘要 文章以WLAN指纹定位技术为参考,在WLA指纹库的基础上,计算待定位物体MS到所有可见AP的距离,构成距离指纹数据库,根据MS测得的3个最强AP的信号,在指纹库中匹配三个AP,利用几何原理计算出MS的坐标,从而到达定位目的。 Taking WLAN fingerprint positioning technology as a reference, on the basis of WLA fingerprint storehouse, this paper calculated the distance of object MS to be positioned to all visible AP, constituted distance fingerprint database, measured three strongest AP signal based on the MS, matched three AP in fingerprint storehouse, and calculated the coordinates of the MS with geometric principle, so as to reach the positioning purpose.
