Problems solved by technology

The above-mentioned measuring instruments are all contact-type, and during the test, the interrogated person can clearly perceive that he is in the state of being tested. First, it will cause the interrogated person to have psychological or physical resistance; Psychological pressure on people will lead to deviations in the test results, and may even lead to wrong test results; third, the interrogated persons who have a certain ability to control their own psychology and physiology can carry out active behavioral confrontation to make the test results produce bias, which may even lead to erroneous test results
[0003] Moreover, the interrogation realized by polygraph technology can only intuitively judge whether the person being interrogated has lied or not, and the final conclusion needs reasonable reasoning to be drawn, which requires relatively cumbersome steps

Embodiment 1

[0058] like figure 1 As shown, a non-contact auxiliary interrogation device includes an interrogation device, an image collection device, a voice collection device, an analysis device, and a display device. The display device is electrically connected with the inquiry device, the analyzing device, the voice collecting device and the image collecting device respectively; the analyzing device is also electrically connected with the image collecting device. The parsing device includes a face collector, a micro-expression sequence parser, a face blood spectrum parser and a comprehensive polygraph parser.

[0059] The inquiry device includes a display screen and a sound. The interrogation device can play questions to the interrogated person and show evidence, such as photos, videos, audios, etc. to the interrogated person. The audio of the interrogation device includes machine audio in the form of speech synthesis and artificial audio in which interrogators ask questions. The in...

Abstract

The invention discloses a non-contact auxiliary interrogation device, which comprises an image acquisition device, a voice acquisition device, an analysis device and a display device, wherein the display device is electrically connected with an inquiry device, the analysis device, the voice acquisition device and the image acquisition device; the analysis device is also electrically connected withthe image acquisition device; the analysis device comprises a face collector, a micro-expression sequence analyzer, a face blood spectrum analyzer and a comprehensive lie detection analyzer; and thecomprehensive lie detection analyzer comprises a basic index receiver, a lie detection comprehensive index generator and a lie detection conclusion generator. According to the device and the method provided by the invention, non-contact acquisition observation is adopted, so that the interrogated personnel can be unperceived, psychological burdens cannot be generated to the interrogated personnel,and the phenomenon that the interrogated personnel are resisted is avoided.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to a non-contact auxiliary interrogation device and method. Background technique [0002] Current interrogation technology is mainly realized by polygraph technology, which usually measures a person's physiological changes through three aspects, which include pulse, respiration and skin resistance. The skin resistance is generally tested by an electrodermal sensor worn on the finger of the interrogated person, and the skin point sensor is generally a stainless steel electrode with a shelf as the outer tube; the respiration is generally carried out by a breathing sensor tied to the chest of the interrogated person In the test, the breathing sensor is a stretch sensor; the pulse is generally measured by a pulse and blood pressure sensor worn on the wrist or arm of the interrogated person, and the pulse and blood pressure sensor is a pressure sensitive sensor or a sphygmomanometer. Th...
