Embodiment Construction

[0041]The interrogation auxiliary research and judgment analysis system based on eye features of the present invention includes two infrared light sources 2, two eye cameras 3 for image acquisition, a projector and its screen or scene display 6, and a computer 4 with built-in video images capture card, operator display 5, such as figure 1 and figure 2 shown;

[0042] The infrared light source 2 is a near-infrared LED light source with a wavelength of 850nm. In order to obtain a stable head and eye image, two near-infrared LED light sources are respectively placed in front of both sides of the head of the user 1 to reduce the risk caused by the rotation of the head. Cause the shadow of the face, the system can be used in daytime and night, has adopted the near-infrared band-pass filter (can only pass through the light that wavelength is 850-890nm), described eye camera 3 adopts high-resolution camera, its Placed on a table 80-100cm away from the tester, the camera uses an in...

Abstract

The invention relates to an eye characteristic-based trial auxiliary study and judging analysis system, which comprises an infrared light source, an image collection unit, an eye detection and tracking unit, a pupil data acquiring unit and a sight tracking and correcting unit. An infrared camera is used for capturing a pupil image data to analyze the eye structure, automatically recognize the central position of the pupil and the central position of a cornea and display relevant data in real time so as to immediately determine the sight direction, and a psychological status of a criminal party can be immediately calculated according to the status variation and the visual content of the pupil. Due to the adoption of the eye characteristic-based trial auxiliary study and judging analysis system, interference on a user is less, and no wearing tracking device is required; and the involved sight tracking technology is one of key technologies of intelligent human-machine interfaces in the future, and the system has wide application prospect on the aspects such as industrial control, robotics and clinical medicine.

Description

technical field [0001] The present invention relates to a technology for reading and analyzing eyeball features, in particular to an eyeball feature-based interrogation assistance analysis system. Background technique [0002] Psychological research shows that the human brain will leave certain imprints on external stimuli, that is, memory. These memories will exist in people's minds for a long time. When these memories are brought up again, especially some bad memories that try to avoid, they will inevitably cause heavy psychological pressure or psychological reactions of the testees, which will cause a series of physiological problems. Abnormal reactions, such as dilated pupils, slight rise in body temperature, sweating, increased breathing rate, etc. These responses vary with mood and behavior. [0003] The current detection method mainly measures the following three physiological changes: [0004] The first indicator is skin galvanic. Because skin electricity is actu...
