System and method of fatigue detection

Abstract

A system of fatigue detection includes an image sensor, a voice sensor, a memory and a processor. The image sensor is configured to capture at least one facial image of a driver. The voice sensor is configured to collect a voice of the driver. The memory is configured to store the at least one facial image and the voice. The processor is configured to extract at least one micro-expression feature from the at least one facial image, and establish a fatigue detection model based on the at least one micro-expression feature, and utilize the fatigue detection model to obtain a fatigue detection result. The processor is further configured to utilize a voice detection algorithm to recognize the voice to obtain a voice recognition result. The processor is further configured to determine a mental state of the driver based on the fatigue detection result and the voice recognition result.
