摘要
针对现有室内基于Wi-Fi的指纹定位技术中指纹样本库会过时的问题,本文提出了一种基于众包的指纹更新技术,该指纹更新技术能够结合实际的移动情境而不断更新样本库中的指纹,保持样本库中指纹的准确性,从而改进了已有的基于Wi-Fi的室内定位技术的精度。
To address the problem that the fingerprint sample libraries become obsolete in the existing indoor fingerprint posi- tioning technology based on WI-FI, this paper proposes the fingerprint update technology based on crowdsourcing, the technology can update the sample library of fingerprints by combining with the actual mobile context, keep the accuracy of the fingerprint sample libraries, and thus improve the precision of the existing indoor positioning technology based on WI-FI.
