Non-contact conversation confidence rate test system and method

Abstract

The embodiment of the invention discloses a non-contact conversation confidence rate test system and method. The system comprises an image collection module which is used for continuously collecting the vibration of tiny muscles of the face, neck and other parts of the body of a to-be-tested person and the overall change of the body, and then obtaining video image information; an image analysis module is used for obtaining vibration parameters of the to-be-tested person according to the pixel point vibration frequencies and amplitudes of the multiple frames of images continuously collected by the image collection module; a storage module is used for storing standard parameters reflecting psychological and physiological states and emotion changes; a comparison and judgment module is used for comparing the vibration parameters of the to-be-tested person with standard parameters to obtain a physiological reaction change index of the to-be-tested person and further obtain a lie index reflecting the credibility of the statement content of the to-be-tested person. The embodiment of the invention provides the non-contact conversation confidence rate test system and the non-contact conversation confidence rate test method, which are used for solving the problem of poor sensitivity and reliability of non-contact equipment or psychophysiological information lack in the prior art.

Description

technical field

[0001] Embodiments of the present invention relate to the technical field of video image acquisition, and in particular to a non-contact conversation confidence rate testing system and method. Background technique

[0002] Any changes in human physiology will be related to the response of human physiological characteristics. In order to obtain comprehensive information on psychophysiology related to the human body, various studies have been conducted so far. Concretely, various implementation technologies such as contact methods, devices, and systems are known. These are well known for medical diagnosis by using parameters of known human physiological signals to assess the emotional and psychological state of a person. The most widely known system for applying physiological signals is called "lie detector". Special external stimuli, such as verbal stimuli, cause changes in each parameter of the psychophysiological properties (psychophysiological) of the hum...
