摘要

几十年来，低功耗蓝牙(BLE)揭示了许多有趣的机会，特别是在定位领域，使其成为室内定位解决方案中最常用的技术之一。我们提出的系统是BLE, Acoustic和LiFi技术的结合。我们的方法不仅仅是算术，而是使用实时计算指标，这些指标可以作为每种技术给出的结果的精度指标或“精度稀释度”(DOP)权重。根据这些类似于dopa的指标，我们能够判断返回结果的精确度和准确性。实验结果表明，当使用这些新的精度指标时，新的混合系统的精度大大提高。

Evaluating Precision of a new Hybrid Indoor Localization System

Bluetooth Low Energy (BLE) has revealed for decades many interesting opportunities especially in the field of positioning that made of it one of the most used technologies in indoor localization solutions. The system we propose is a combination of BLE, Acoustic and LiFi technologies. Our approach is not just arithmetic but using real time computed metrics that act precision indicators or "Dilution of precision" (DOP) weights of the results given by each technology. Depending on these DOP-like indicators, we were able to judge how much precise and accurate the returned results are. Our new approach was confirmed during experiments showing that the precision of this new hybrid system is much better when using these new precision metrics.
