Title:
FATIGUE DETECTION METHOD AND SYSTEM BASED ON MULTI-DIMENSIONAL BODY STATE SENSING
Document Type and Number:
WIPO Patent Application WO/2023/036015
Kind Code:
A1
Abstract:
Disclosed in the present invention are a fatigue detection method and system based on multi-dimensional body state sensing. The method comprises: collecting infrared image data of a facial feature by means of an infrared technique, pre-processing the infrared image data, extracting facial information from the infrared image data, extracting eye feature data and mouth feature data from the facial information, detecting a facial fatigue state by means of analyzing the eye feature data and the mouth feature data, and acquiring a facial fatigue detection result; collecting sound information by means of a speech input module, detecting a speech fatigue state on the basis of the sound information, and acquiring a speech fatigue detection result; and fusing the facial fatigue detection result and the speech fatigue detection result, performing multi-classifier fusion on the basis of information entropy selection, and fusing the content of a decision table, so as to obtain a final human body fatigue detection result. In the embodiments of the present invention, the fusion of various pieces of fatigue detection information is provided, thereby improving the effectiveness of a whole system.
