声学室内定位-一种使用声学信号定位建筑物内物体或人员的技术-是上下文感知和普适计算的关键技术。为了实现简单的定位,本文提出了一种基于转发器的室内定位方法。所提出的方法不需要时钟同步精确定位。此外,通过使用自适应信号电平归一化器,终端可以接收具有适当电平的声学信号,从而导致精确定位。设计了一种基于应答器的室内可听声定位方法,并对其性能进行了实验评估。在实验中,已知位置的三个锚(应答器)安装在消声室的天花板上,并且通过在各个点设置终端来执行定位。定位实验结果表明,该方法可以实现0.08 ± 0.02 m量级的定位。
Acoustical indoor positioning — a technology to locate objects or people inside a building using acoustical signals — is a key technology for contextual awareness and ubiquitous computing. To achieve simple localization, in this paper, we propose a transponder-based indoor positioning method. The proposed method does not require clock synchronization for accurate positioning. Furthermore, by using an adaptive signal level normalizer, the terminal can receive acoustic signals with appropriate levels resulting in accurate positioning. We designed a transponder-based indoor positioning method using audible sound and evaluated its performance in experiments. In experiments, three anchors (transponders) of known position are installed on a ceiling of an anechoic chamber, and positioning is performed by setting a terminal in various points. Positioning experiment results showed that the proposed method can achieve on the order of 0.08 ± 0.02 m positioning.
