Abstract: A vehicle mounted liveness detection system, liveness detection method, apparatus, computer device and storage medium are disclosed. The system includes a Doppler microwave sensor, a camera and an alarm controller. The Doppler microwave sensor is configured to perform a liveness search on an in-vehicle space, obtain a liveness search data, and 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 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 and 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 and the in-vehicle image.
