METHOD AND DEVICE FOR MONITORING DANGEROUS PERSON ON BASIS OF VIDEO PSYCHOPHYSIOLOGICAL PARAMETERS

摘要

A method and device for monitoring a dangerous person on the basis of video psychophysiological parameters. The device comprises: an acquisition unit (100) for acquiring video information of a test subject; a generation unit (200) for processing the video information to generate a related biological signal containing a danger level; and a processing unit (300) for obtaining the danger level of the test subject according to a vibration frequency and/or an amplitude of the biological signal. The device and method are advantageous in easy implementation through the processes of capturing video image information of the test subject in a biological signal acquisition mode, analyzing the test subject with the video stream information to extract vibration parameters, then generating all parameters of psychophysiological characteristics on the basis of the vibration parameters, and starting signal extraction of the physiological characteristics of the test subject with the parameters.
