Respiratory rate (RR) is one of the vital signs which is commonly measured by contact-based methods, such as using a breathing belt. Recently, significant research has been conducted related to contactless RR monitoring - however, the majority of experiments are performed in situations when the subject is oriented towards the radar. In this research, we are interested in monitoring the breathing of subjects who can be anywhere in the room. A system of three impulse radio ultrawideband (IR-UWB) radars is used to cover the whole room. A Kinect camera that can track subjects' joints 3D coordinates was employed to localize the subjects. The results of RR monitoring using IR-UWB radars and Kinect camera show good performance in single/multiple subject(s) tracking and RR estimation.
呼吸频率（RR）是常用基于接触的方法测量的生命体征之一，例如使用呼吸带。最近，已经开展了与非接触式RR监测相关的大量研究——然而，大多数实验是在受试者面向雷达的情况下进行的。在本研究中，我们感兴趣的是监测房间内任何位置的受试者的呼吸情况。使用一个由三个脉冲无线电超宽带（IR-UWB）雷达组成的系统来覆盖整个房间。采用一个能够跟踪受试者关节三维坐标的Kinect相机来对受试者进行定位。使用IR-UWB雷达和Kinect相机进行RR监测的结果在单/多受试者跟踪和RR估计方面表现良好。
