Abstract

The invention discloses a system, method and device for assisted judgment of the psychological state of an object in a trial scene. The method comprises the steps of acquiring a first facial expression of the object at the first moment and a second facial expression of the object at the second moment; acquiring a first detection point of the first facial expression located at a preset detection position and a second detection point of the second facial expression located at a preset detection position; acquiring the detection position difference value of the first detection point and the second detection point according to the positions of the first detection point and the second detection point; comparing the detection position difference value with a preset detection threshold value to obtain the psychological state of the object. The problem can be solved that in the related art, the psychological state of the tried object cannot be accurately judged in the trial process, and thus the purpose of accurately knowing the psychological state of the tried object in the trial 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 assisting the judgment of an object's psychological state in an interrogation scene. 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 the interrogators to make human judgments. However, in the process of human judgment, it is limited by personal experience and analysis ability, so it is impossible to ensure that the psychological state of the interrogated object is accurate. judgment. [0003] Regarding the problem in the related technology that the psychological state of the interrogated object cannot be accurately judged duri...
