| description | The invention relates to a living body detection method based on a UWB technology. The method for detecting the living body in the vehicle comprises the steps that radar output data generated by a radar device arranged in the vehicle are obtained, and the radar output data are generated according to a pulse signal emitted by the radar device and an echo signal which is returned after the pulse signal interacts with an object to be detected and is received by the radar device; determining a detection distance and a detection speed of the to-be-detected object relative to the radar device according to the radar output data; and determining whether the to-be-detected object is a living body according to the detection distance and the detection speed of the to-be-detected object relative to the radar device.
本公开涉及一种基于UWB技术的活体检测方法。其中，用于检测车辆中的活体的方法包括：获取设置在车辆内的雷达装置产生的雷达输出数据，其中，雷达输出数据是根据雷达装置所发射的脉冲信号和脉冲信号与待测对象相互作用后返回而被雷达装置所接收的回波信号生成的；根据雷达输出数据，确定待测对象相对于雷达装置的检测距离和检测速度；以及根据待测对象相对于雷达装置的检测距离和检测速度，确定待测对象是否为活体。 |
