The invention provides an in-vehicle living body detection method and device, a vehicle, equipment and a storage medium, and the method comprises the steps: carrying out the first sampling of an original detection signal received by a receiving node in double-station nodes in a to-be-detected vehicle, and obtaining a living body detection signal sequence; detecting a detection channel complex signal of the sampling channel according to the in-vivo detection signal sequence to generate a detection complex vector, generating a detection digital time-frequency signal, inputting the detection digital time-frequency signal into a pre-trained respiration detection model to obtain an initial detection result, and further generating an in-vehicle in-vivo detection result of the to-be-detected vehicle. High-quality respiration signals can be extracted by using the in-vehicle receiving equipment and the in-vehicle sending equipment, detection is performed through a pre-established respiration detection model, the in-vehicle double-station nodes are more robust to environmental noise and better in detection performance, and the in-vehicle double-station nodes can be realized by completely or partially multiplexing nodes of other systems, such as a digital key system, a digital key system and a digital key system. The cost can be obviously reduced, and the accuracy is higher.

    本申请提供一种车内活体检测方法、装置、车辆、设备及存储介质,该方法通过对待检测车辆的车内的双站节点中接收节点所接收的原始检测信号进行第一采样得到活体检测信号序列,根据活体检测信号序列检测采样通道的检测通道复信号生成检测复向量,并生成检测数字化时频信号,将该检测数字化时频信号输入到预先训练的呼吸检测模型,得到初始检测结果,进而生成该待检测车辆的车内活体检测结果,通过使用车内接收设备和车内发送设备这一双站节点可以提取出更高质量的呼吸信号,通过预先建立的呼吸检测模型进行检查,对环境噪声更鲁棒,检测性能更好,车内双站节点可全部或部分复用其他系统的节点实现,如数字钥匙系统,可显著降低成本,准确性更高。
