Intelligent interrogation research and judgment method

Abstract

The invention relates to the technical field of interrogation, in particular to an intelligent interrogation research and judgment method. The method comprises the following steps: A) uninterruptedly acquiring face video data of a tested object through a camera, and performing face positioning and recognition on the video; collecting sound data of the tested object through a microphone; b) calculating the heart rate, the blood pressure, the respiration rate and the heart rate variability of the tested object by positioning and extracting the blood volume pulse signal of the tested object in the video; extracting sound emotion characteristic parameters of the tested object, and establishing an LSTM (Long Short Term Memory) model for the sound; and C) on the basis of the big data, calculating the heart rate, the blood pressure, the respiration rate and the heart rate variability of the tested object, and obtaining parameters. According to the method, the face video data and the sound data of the interrogated person are acquired, and the face video data and the sound data are calculated to assist the interrogation person in discrimination, so that the interrogation time can be effectively shortened, and the interrogation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of interrogation, in particular to an intelligent interrogation and judgment method. Background technique [0002] At present, the existing interrogation, investigation and judgment of the interrogated personnel are all judged by the interrogators. This operation method relies heavily on the past experience of the interrogators, and consumes a lot of manpower, material resources, time and resources, and is inefficient. The commonly used polygraph and other equipment need to be installed on the person being interrogated, which can easily make them nervous and interfere with the test results. And the measured indicators are relatively single, so the effect of auxiliary research and judgment is limited. SUMMARY OF THE INVENTION [0003] In order to solve the deficiencies of the prior art described in the background art, the present invention provides an intelligent interrogation research and judgment method....

Problems solved by technology

[0002] At present, the existing interrogation and judging of the interrogated persons are all judged by the interrogators. This operation method is very dependent on the past experience of the interrogators, and consumes a lot of manpower, material resources, time and resources, and the efficiency is not high.

The commonly used polygraph and other equipment need to be installed on the person being interrogated, which can easily cause tension and interfere with the test results; at the same time, when the subject knows the polygraph, he will increase his vigilance and affect the interrogation effect

And the measured indicators are relatively simple, so the effect of auxiliary research and judgment is limited
