Abstract

Wi-Fi fingerprint positioning has the advantages of being infrastructure-less and easily accessible, but the weaknesses in terms of lower accuracy and limited Wi-Fi scanning speed are also hard to tackle. On the other hand, with the progress in computer vision and deep learning, vision-based positioning based on commonly available surveillance cameras becomes a promising solution for providing location-based services. But the major difficulty lies in checking the identity of detected people just by the captured images. This paper proposed a novel Matching Mechanism to address the identity matching problem, which associates the non-identifiable positioning sources like vision to the easily identifiable positioning sources like smart phone’s Wi-Fi. Practicalities like scalability and online operation are considered in both the design and implementation of the mechanism. As a result, the experiment not only proved the effectiveness of matching the vision-based and Wi-Fi positioning results but also showed an improvement in positioning accuracy by over 60%.
一种在线异构定位融合系统的可扩展匹配机制
Wi-Fi指纹定位具有不需要基础设施和易于访问的优点,但精度较低和Wi-Fi扫描速度有限的缺点也难以解决。另一方面,随着计算机视觉和深度学习的进步,基于常见监控摄像头的视觉定位成为提供位置服务的一种很有前途的解决方案。但主要的困难在于仅凭捕获的图像来检查被检测人员的身份。本文提出了一种新的匹配机制来解决身份匹配问题,该机制将视觉等不可识别的定位源与智能手机Wi-Fi等易识别的定位源相关联。该机制的设计和实现都考虑了可扩展性和在线操作等实用性。实验结果证明了基于视觉和Wi-Fi的定位结果匹配的有效性,定位精度提高了60%以上。
