本申请实施例提供一种非接触式生命体征检测方法、检测装置和电子设备，该装置包括：频点确定单元，其根据被检测体与接收装置之间的距离的范围，基于所述反射信号的相位确定用于生命体征检测的频点或基于所述反射信号的幅值确定用于生命体征检测的频点；以及检测单元，其基于被确定的频点，根据所述反射信号在所述频点处的相位信息检测所述被检测体的体征信息。根据本申请，能够通过合理地设定检测用频点，提高对生命体征的检测精度。 The invention provides a non-contact vital sign detection method, a detection device thereof and electronic equipment. The device includes a frequency point determination unit that determines a frequency point for vital sign detection based on a phase of a reflected signal or determines the frequency point for vital sign detection based on an amplitude of the reflected signal according to a rangeof a distance between a subject and a receiving apparatus; and a detection unit that detects sign information of the subject from phase information of the reflected signal at the frequency point on the basis of the determined frequency point. According to the vital sign detection method and device thereof, the detection precision of vital signs can be improved by reasonably setting the frequency points for detection.
