摘要:

现有的室内定位系统基本上依赖于无线信号。随着低成本摄像机的大量部署,基于视觉图像的定位也变得很有吸引力。然而,在现有的文献中,混合的视觉和无线的方法简单地结合了上述计划在一个简单的方式,并没有探讨它们之间的相互作用。本文提出了一种基于视觉和无线信号特征的高精度室内定位方法。在该联合方案中,WiFi信号被用来计算与似然概率的粗区域和视觉图像被用来微调定位结果。基于数值计算结果,我们表明,该方案可以达到0.62米的定位精度与近实时运行时间。

英文摘要:

The existing localization systems for indoor applications basically rely on wireless signal. With the massive deployment of low-cost cameras, the visual image based localization become attractive as well. However, in the existing literature, the hybrid visual and wireless approaches simply combine the above schemes in a straight forward manner, and fail to explore the interactions between them. In this paper, we propose a joint visual and wireless signal feature based approach for high-precision indoor localization system. In this joint scheme, WiFi signals are utilized to compute the coarse area with likelihood probability and visual images are used to fine-tune the localization result. Based on the numerical results, we show that the proposed scheme can achieve 0.62m localization accuracy with near real-time running time.
