Title:
LIVING BODY DETECTION METHOD AND DEVICE, AND DRIVING RECORDER
Document Type and Number:
WIPO Patent Application WO/2021/003841
Kind Code:
A1
Abstract:
A living body detection method and device, and a driving recorder. The method is applied to the living body detection device. The living body detection device comprises at least two signal transmitters and signal receivers arranged corresponding to the signal transmitters, and the union of sub-areas covered by signals transmitted by the signal transmitters covers an area to be detected. The method comprises: generating and modulating detection wave signals to obtain at least two modulated detection wave signals (S101); transmitting the modulated detection wave signals (S102); receiving reflected wave signals corresponding to the modulated detection wave signals (S103); and decoding and demodulating the reflected wave signals to obtain target signals, and detecting whether each of the target signals includes a vital sign signal, and when there is a vital sign signal in the at least one target signal, determining that there is a living body in the area to be detected (S104). By means of the method, synchronous detection in the entire coverage range of the area to be detected can be realized, thereby avoiding missing detection.
