1. A vehicle mounted liveness detection system, comprising a Doppler microwave sensor, a camera, and an alarm controller;
wherein the Doppler microwave sensor is configured to perform a liveness search on an in-vehicle space, to obtain a liveness search data, and to transmit the liveness search data to the alarm controller;
the camera is configured to capture an in-vehicle image of the in-vehicle space and to transmit the in-vehicle image to the alarm controller;
the alarm controller is configured to:
perform a liveness detection on the liveness search data;
perform a liveness detection on the in-vehicle image;
determine that a presence of liveness in the in-vehicle space is detected based on the liveness search data when a first liveness detection result obtained by performing the liveness detection on the liveness search data meets a preset first alarm condition; and
determine that a presence of liveness in the in-vehicle space is detected based on the in-vehicle image when a second liveness detection result obtained by performing the liveness detection on the in-vehicle image meets a preset second alarm condition; and
the alarm controller is also configured to perform an in-vehicle liveness alarm operation when a presence of liveness in the in-vehicle space is detected based on at least one of the liveness search data or the in-vehicle image.
