Research on the Principle of Multimodal Intelligent Interrogation Technology and Its Practical Application Path
Multimodal intelligent interrogation technology realizes intelligent analysis and evaluation of suspect's psychology and lie detection during interrogation through non-contact physiological detection,facial expression and limb movement analysis,eye movement detection and other multi-source heterogeneous data fusion algorithms.Input the psychological analysis and evaluation opinions of suspect into the interrogation expert system,collide with a large number of expert knowledge and experience in the knowledge base,and output interrogation strategy suggestions,so as to provide expert services for investigators.The development of multimodal intelligent interrogation technology requires collecting real data in the interrogation room,constructing a large and reliable database,and fully mining and utilizing different modal data to build a human-machine integration interrogation technology that synchronizes multimodal intelligent interrogation technology with interrogation expert systems,to assist in interrogation.As a typical representative of interrogation technology,multimodal intelligent interrogation technology has changed the traditional experience mode mainly based on human resources,undoubtedly bringing new vitality and profound changes to interrogation.
