The invention discloses a living body detection method, a living body detection device, electronic equipment, a vehicle and a computer readable storage medium. The in-vivo detection method is used for a vehicle, and specifically comprises the following steps: in response to an ultra-wideband pulse signal generated in a vehicle cabin, obtaining original channel pulse response data fed back by an internal environment of the vehicle cabin; performing signal preprocessing on the original channel pulse response data to determine channel pulse data so as to improve the accuracy of a living body detection signal; and determining a living body detection signal according to the channel pulse data so as to detect whether a living body exists in the vehicle cabin or not. According to the method, the CIR data in the internal environment of the vehicle cabin can be obtained by receiving and transmitting UWB signals in the vehicle cabin, signal preprocessing is firstly performed before living body detection judgment is performed based on the CIR data so as to adjust the parameter performance of the obtained CIR data which can influence the quality of the CIR data, the accuracy of the CIR data is improved, and the accuracy of the CIR data is improved. And thus, the effectiveness degree and the accuracy degree of living body detection are improved.

    本申请公开了一种活体检测方法、活体检测装置、电子设备、车辆及计算机可读存储介质。活体检测方法用于车辆,具体包括:响应于向车辆座舱内部产生的超宽带脉冲信号,获取车辆座舱内部环境反馈的原始信道脉冲响应数据;对原始信道脉冲响应数据进行信号预处理,确定信道脉冲数据,以提高活体检测信号的精确度;根据信道脉冲数据,确定活体检测信号,以检测车辆座舱内是否存在活体。本申请可以利用车辆座舱内部UWB信号的收发来获取车辆座舱内部环境中的CIR数据,在基于CIR数据进行活体检测判断之前首先进行信号预处理,以调整获取到的CIR数据自身能够影响CIR数据质量的参数表现,提高CIR数据的精确度,进而提高活体检测的有效程度与精确程度。
