Abstract

The invention discloses an interrogation process object judgment system, method and device based on face recognition, and the method comprises the steps: obtaining a first face image of an object at afirst moment and a second face image of the object at a second moment; obtaining a first sub-image and a second sub-image according to the first face image and the second face image respectively; acquiring an image overlap ratio between the first sub-image and the second sub-image, comparing the image overlap ratio with a preset threshold, and acquiring an image change value of the second sub-image relative to the first sub-image when the image overlap ratio exceeds the preset threshold; and judging the object according to the image change value. According to the invention, the problem that the psychological state of the interrogation object cannot be accurately judged in the interrogation process in the prior art can be solved; therefore, the interrogator is assisted to accurately know the psychological state of the interrogating object in the interrogating process.

Description

technical field [0001] The invention relates to the field of office assistance, in particular to a system, method and device for judging objects in an interrogation process based on facial recognition. 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 during the inter...
