Description
Technical field
The utility model belongs to biometrics identification technology, relates in particular to a kind of portrait comparison system that is applied to public security system.
Background technology
As a kind of important identify label, human face image information plays a part very important in the public security system related service.In daily patrol, household register investigation, entry-exit management and criminal case investigation, the policeman can examine related personnel's identity through identification people face.Yet, only carry out the demand that human face recognition can't satisfy related service with manpower.For example, the patrol police carries out can only judging when interrogate and examine on the road surface whether interrogated and examined object consistent with certificate photograph, can't judge but whether it is the people at highest risk, personnel deploy to ensure effective monitoring and control of illegal activities.During public security, criminal investigation are used, after being arrested, the suspect tends to refusal report or false newspaper identity, to disperse, to obscure policeman's energy.In the frequent place of some business processing, like entry-exit management, the policeman is difficult to constantly keep hig diligence power that related personnel's identity is examined.For another example, in the Internet bar, hotel, big assembly place, the personnel identity that gets in the place is complicated, and source of personnel is extensive, and uncertain factor is many, depends merely on the true identity that manpower can't directly be distinguished personnel, for emergency situations shortage control.
The personnel identity that current public security occurs needing to be resolved hurrily in using is examined problems such as effect in the work, efficient, main cause be lack efficiently, the authentication means of intelligence.And face recognition technology is as a kind of contactless biological identification technology; Characteristics such as have reliable, nature (to carry out the biological characteristic that individual identification utilizes identical with the mankind) and be difficult for discovering; Can seamlessly incorporate existing public security work pattern, the quick and accurate of providing convenience authentication means.
The fast development of technology such as Along with computer technology, photoelectronic imaging technology, image processing techniques and pattern-recognition; A kind of brand-new human body biological characteristics recognition technology has appearred; So-called human body biological characteristics identification; Be meant through computing machine with human body intrinsic physiological characteristic or behavioural characteristic collect and handle, carry out the technology that personal identification is screened.Physiological characteristic is inherent, is mostly geneogenous; Behavioural characteristic then is that custom makes so, is mostly that form the day after tomorrow.Scientist is referred to as biological characteristic with physiology and behavioural characteristic, and the development of biometrics identification technology has expedited the emergence of a new industry, and the annual value of production in this field has reached multi-billion dollar at present, and is rapid growth situation.
Face recognition technology is exactly to utilize people's facial characteristics and the relation between the characteristic to come a kind of human-body biological recognition technology that the people is discerned.Face recognition technology comprises the detection of people's face, face tracking and people's face than reciprocity problem, and people's face detects and is meant in dynamic scene and complicated background, judges whether to exist people's face and isolates people's face; Face tracking refers to the people's face that is detected is carried out dynamic target tracking; The comparison of people's face then is that the people's face that is detected is carried out identity validation or in face database, carries out the target search comparison.
Because human body biological characteristics has not reproducible uniqueness and stability, and can not be replicated, have things stolen or forget.So, utilize these unique biological characteristics of human body can discern, differentiate everyone identity exactly.The human body biological characteristics recognition technology of current successful Application and Development has fingerprint, palmmprint, eye iris, sound, people's face, signature and DNA etc., and face recognition technology then has with respect to the other biological recognition technology in the human body biological characteristics recognition technology of having developed: quick, easy, non-invasion, do not need the people by movingly; Good false proof, anti-swindle characteristic, accurate, directly perceived, convenient; Cost performance height, economy, extensibility are good.Therefore can be widely used in the parties concerned such as gateway control, safety verification, safety monitoring and search criminal.
