摘要:针对复杂室内环境造成的室内定位技术不同于室外定位技术的问题,提出了一种基于楼层判别和信号强度的室内AP混合定位方法。该方法由AP的楼层判别和具体位置的定位两部分组成。首先用关联算法对AP进行楼层判别以筛选出目标AP,然后根据测试点与目标AP的位置关系确定定位方法。如果目标AP在测试点附近,采用简单的质心定位算法,否则采用加权式的定位算法。在实际场景中的定位测试结果表明,该方法定位效果良好,偏差较小。
For the distinctive characteristics of indoor positioning technology which is different from outdoor positioning due to the complexity of the indoor environment
an indoor AP hybrid positioning method based on floor discrimination and signal strength was proposed. The method consists of two parts
the floor discrimination and the specific location of the AP. The method using association algorithm to determine the floor in order to filter out the target AP
and then it to determine the positioning method according to the position relationship between the test point and the target AP. If the target AP in the vicinity of the test point
the centroid localization algorithm was used
otherwise the weighted-style positioning algorithm was used. The positioning test results in the actual scene show that the positioning effect of the method is good and the method has a small deviation.
