The invention relates to a living body detection method and device, a vehicle and a storage medium. The method comprises the following steps: in response to detecting that a vehicle door is switched from an open state to a closed state, controlling an in-vehicle loudspeaker to emit a first sound wave signal; controlling an in-vehicle microphone to collect a second sound wave signal corresponding to the first sound wave signal; determining channel state information of the second sound wave signal according to the first sound wave signal and the second sound wave signal; according to the channel state information of the second sound wave signal, a living body detection result is determined, and the living body detection result is used for indicating whether a living body exists in the vehicle or not. Therefore, the detection of the living body in the vehicle can be realized by transmitting and receiving the sound wave signal through the loudspeaker and the microphone which are arranged in the vehicle, other detection equipment does not need to be additionally arranged, and the living body detection can be realized on the basis of the existing equipment in the vehicle. In addition, sound wave signal transmitting and receiving of the loudspeaker and the microphone in the vehicle are not prone to being affected, and stability and accuracy of in-vivo detection can be guaranteed.
本公开涉及一种活体检测方法、装置、车辆及存储介质。所述方法包括:响应于检测到车门由开启状态转换至关闭状态,控制车内扬声器发出第一声波信号;控制车内麦克风采集对应于所述第一声波信号的第二声波信号;根据所述第一声波信号和所述第二声波信号,确定所述第二声波信号的信道状态信息;根据所述第二声波信号的信道状态信息,确定活体检测结果,所述活体检测结果用于指示车内是否存在活体。由此,通过车内设置的扬声器和麦克风对声波信号的收发,即可实现对车内活体的检测,无需额外设置其他检测设备,在车内已有设备的基础上就能实现活体检测。并且,车内扬声器和麦克风的声波信号收发不易受到影响,有利于保证活体检测的稳定性与准确性。
