Abstract

The invention discloses a system, method and device for identifying psychological state of interrogation object based on multidimensional judgment, wherein the method comprises the following steps of:acquiring a first face image of the object at a first moment and a second face image at a second moment, wherein the first moment is before the second moment; acquiring a heart rate and breathing frequency of the object through a millimeter wave radar at a third moment, and comparing the heart rate and breathing frequency of the object with preset threshold values, wherein the third moment is between the first moment and the second moment; acquiring an image difference value between the first face image and the second face image when the heart rate and the breathing frequency of the object exceed the threshold values; judging the psychological state of the object according to the image difference value. The method can solve the problem that the psychological state of the interrogation object cannot be accurately judged in the interrogation process in the prior art; therefore, the purpose of assisting interrogators to accurately know the psychological state of the object in the interrogation process is achieved.

Description

technical field [0001] The invention relates to the field of office assistance, in particular to a system, method and device for identifying the mental state of an interrogation object based on multidimensional judgment. Background technique [0002] During the interrogation process, public prosecutors and relevant judicial departments often face false information fed back by interrogators, which will seriously affect the efficiency of interrogation and subsequent investigation and analysis. At present, in related technologies, the above-mentioned problems mainly rely on the experience of interrogators to make human judgments, or use equipment similar to a lie detector to evaluate the psychological state of the subject. However, in the above scheme, the judgment by the interrogator is too dependent on human experience, while the judgment by the polygraph requires contact with the subject, which may have a certain impact on the result. [0003] Regarding the problem in the r...
