The invention discloses a living body detection method, device and equipment and a storage medium thereof, and belongs to the technical field of radar. The living body detection method is applied to the vehicle, a radar is arranged in the vehicle, and the method comprises the following steps: responding to a vehicle locking instruction, and dynamically obtaining an echo signal collected by the radar; determining a signal change rate of the echo signal within a preset duration; if the signal change rate is larger than a preset signal change rate threshold value, it is judged that a living body exists in the vehicle. The in-vehicle living body detection method and device solve the technical problem that the accuracy of conventional in-vehicle living body detection is low.
本申请公开了一种活体检测方法、装置、设备及其存储介质,属于雷达技术领域。活体检测方法应用于车辆,车辆的内部设置有雷达,方法包括以下步骤:响应于车辆落锁指令,动态获取雷达采集到的回波信号;确定回波信号在预设时长内的信号变化率;若信号变化率大于预设的信号变化率阈值,则判定车内存在活体。本申请解决了常规的车内活体检测的准确度较低的技术问题。
