本文提出了一种基于超声波传感器的家庭环境中的人的连续和不引人注目的定位的新方法。该方法使用半环，超声波传感器安装在环境的天花板上。通过分析可用传感器的检测到的回波来计算人的位置。在区分由静态环境引起的回波和由人引起的回波之后，仅利用最后提到的回波来确定位置。然后，该位置可以用于进一步的分析，例如移动性评估或用于提供位置相关服务。
In this paper a novel approach to continuous and unobtrusive localization of a person inside his or her domestic environment based on ultrasonic sensors is presented. The approach uses half rings with ultrasonic sensors mounted on the ceiling of the environment. The person's position is computed by analyzing the detected echoes of the available sensors. After distinguishing between echoes caused by the static environment and echoes caused by the person, only the last-mentioned echoes are utilized to determine the position. This position can then be used for further analyses such as mo-bility assessments or for providing location dependent services.
