Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the invention will be further described, can not be used for limiting the scope of the invention.
The present invention is directed to the two problems of the existence in existing video monitoring system, propose the research of the safety monitoring video marking technologies based on recognition of face and infrared perception union feature.Utilize face recognition technology and infrared alarm detection system, real-time protection is carried out to community, and connect with monitor video.The technology using Video processing to combine with recognition of face, by the recognition of face inside video out, and adds bookmark on corresponding frame.By such technological innovation, security protection grade is improved, checks mark part fast when playback, invalid picture is ignored, raises the efficiency, accelerate to check and detection speed.
Before describing the present invention, first cognition technology outside face recognition technology and hole is briefly introduced.
The essence of recognition of face extracts the region meeting face characteristic in video image, and common implementation has complexion model diagnostic method, the face identification method of feature based face (PCA), the face identification method etc. of elastic graph matching.
In safety-security area, infrared technique is generally employed, and is mainly divided into infrared opposite-radiation transducer and pyroelectric sensor two kind equipment.
Infrared opposite-radiation transducer occurs two terminal equipments in pairs, one sends infrared ray, a receiving infrared-ray, infrared ray is linearly propagated, and when not having shelter between two points, the transducer of receiving terminal normally can detect the infrared signal of transmitting terminal, if have shelter in the middle of both, then receiving terminal can not receive infrared signal, and the unlike signal that can change into transducer with or without Signal reception exports, and judges for computer.The operation principle of pyroelectric infrared sensor is: at nature, anyly all infrared spectrum will be produced higher than object time absolute temperature (-273 DEG C), the object of different temperatures, the wavelength of the infrared energy of its release is different, and therefore infrared wavelength is relevant with the height of temperature.Human body or the larger animal of volume have constant body temperature, general at 37 degree, so the infrared ray of specific wavelength about 10 μm can be sent, when human body enters detection zone, because human body temperature and ambient temperature have difference, the infrared ray of about 10 μm of human-body emitting is by gathering on infrared induction source (pyroelectricity element) after the enhancing of Fresnel lens filter, infrared induction source will lose charge balance when receiving human infrared radiation, outside release electric charge, and then produce variations in temperature and by variations in temperature to the periphery circuit export, just alarm signal can be produced after subsequent conditioning circuit processes after testing.If human body is motionless after entering detection zone, then temperature does not change, and transducer does not have signal to export yet, so this transducer is applicable to the active situation of human body or animal.
In the scene domain of camera surveillance, to occur moving target monitor, Classification and Identification.Various infrared surveillance requirement can be set as required, once system monitoring to moving target and behavior meet the Alert condition preset, then automatically produce warning message.
