Description
Technical field
The utility model relates to the safety check system in security field, especially the multifunctional human rays safety detection apparatus.
Background technology
Rays safety detection apparatus is that a kind of testing staff has or not the sniffer that carries dangerous goods, be mainly used in the safety inspection in airport, justice system, station, momentous conference and key activities place, can detect the hazardous metals article of concealing in human body privacy position and the body such as detonator.When the examinee passes through from detector gate, when entrained article such as metal surpass according to the pre-set parameter value of weight, quantity or shape on the person, at once report to the police, and show the position, article place of causing warning, the dangerous goods that allow the security staff in time find this people to be carried.Human body safety check equipment shortcoming commonly used is a poor sensitivity, function singleness, and the supervision time is long, and the inspection at some privacy position is accused of violating human rights.
Summary of the invention
The purpose of this utility model be to provide a kind of highly sensitive, check rapidly, avoid the multifunctional human rays safety detection apparatus of violating human rights.
The utility model is achieved in that the multifunctional human rays safety detection apparatus, it is characterized in that comprising metal detection portion, monitoring video portion, recognition of face portion, touch screen operation display part, audio alert portion totally five major parts, described metal detection portion is divided into and is 16 and surveys positions, and the oscillation frequency difference that adjacent position LC oscillatory circuit produces separates with multilayer aluminium net between the telefault of LC oscillatory circuit and the coil; Described monitoring video portion is made up of video camera, video frequency collection card, computer, USB interface, is connected with other four part respectively; Described recognition of face portion comprises left and right sides dual camera; Described touch screen operation display part comprises tangible formula operating display; Described audio alert portion comprises the alarm sound module; Described metal detection portion, recognition of face portion, touch screen operation display part, audio alert portion all cross USB interface with the computer expert of monitoring video portion and link to each other.
It is 16 detection positions that multi-functional safe examination system metal detection is divided into, and the oscillation frequency difference that adjacent position LC oscillatory circuit produces is to reduce co-channel interference, and between the telefault and coil of LC oscillatory circuit, separate with multilayer aluminium net, be used to shield the frequency interferences that produces between LC position and the position.Each position alerting signal is all passed through the PLC computed in software, and drives demonstration.
The metal detector principle:
Metal detection adopts modern the detection and switch technology, utilize the magnetic strength principle, detect metal, power unit changes 12V by 220V and 24V powers to circuit board, 16 road metal detection districts all form the LC oscillatory circuit by telefault and electric capacity, produce an oscillation frequency, when metal, can change the LC oscillation frequency, the RC frequency selection network, after detecting frequency and changing, send alerting signal, alerting signal is amplified by operational amplifier, and 16 road signals are all changed by A/D, deliver to PLC and carry out the software computing, operation result and touch-screen communication connect machine.Display alarm position on touch-screen, the position of Chinese display alarm simultaneously title, the amount of metal of left and right sides sole shows simultaneously, also is by computed in software, and show.Report to the police in the position arbitrarily, all can trigger audio alert sound, can regulate the sound size on touch-screen.
Monitoring video:
Monitoring video is made up of video camera, video frequency collection card, computer etc.Camera acquisition by video frequency collection card, converts the signal that computer can receive demonstration to signal to.Connect by USB interface.Type of alarm and other function can be set on software.
The recognition of face principle:
Along with development of science and technology, recognition of face is developed at numerous areas, has especially obtained abundant development and application in security protection, anti-terrorism field.A difficult problem and predicament at recognition of face, in actual mechanical process, dual camera method of identification a kind of novel solution of can yet be regarded as: the figure of right side camera levies and carries out people's face location and eye location, simultaneously, the picture of left side camera and right side camera carries out stereoscopic fusion, recovers three-dimensional face model, on this basis, carry out top grade and extract and compare, realize functions such as template typing and identification.Such advantage is in its naturality and the characteristics do not discovered by tested individuality.Its gordian technique have in following some.
People's face detects, and there are two functions the face test section: the one, judge whether there is people's face in the image, and the 2nd, if there is people's face, determine the definite position of people's face, during people's face detects as adopt cascade and the Harr feature carry out people's face location, accuracy is higher, speed is faster.
The human eye location, eyes are parts of most critical in people's face, also are most important zones of distinguishing the different people face, are both by behind accurately the determining of eye position, people's other each organ on the face that can better align is so accurately locate of crucial importance to eyes.Adopt the method for minimal value zone (MER) principle and more multi-layered structure, just can be good at solving the problem of eye location.
Extract feature, feature is meant the one group of vector that can distinguish the different people face that extracts from facial image, also is referred to as to represent for people's face, is illustrated in based on people's face of Gabor small echo and has obtained great success in the recognition of face.Because Gabor small echo primitive character dimension is too high, calculated amount is big, need do dimension-reduction treatment, promptly represents the vector of higher-dimension with the vector of low-dimensional.In order to cross the computing requirement, can adopt tensor subspace analytical approach (being called for short ORO), people's face is represented to regard as a tensor, by the order of alternative manner searching quadrature, a tensor carries out dimensionality reduction, finally can effectively extract core feature.
This method has following advantage: the one, can catch the partial structurtes information of people's face with tensor representation people face; The 2nd, the dimension of each component of tensor is very low, can avoid occurring the dimension disaster problem among the LDA (linear category analysis); The 3rd, the dimensionality reduction matrix of this method is far smaller than the dimensionality reduction matrix of LDA, and this Embedded Application for the limit of some storage spaces is very suitable.
The feature contrast, the feature contrast mainly is the similarity between two different people faces of comparison, effective method promptly is to visit scenic spot the degree of correlation between feature as the description of similarity, in identification people face, all features in image to be identified and the feature database are compared, and its similarity the maximum is matching result.
The model that can show a human body on the described touch screen operation display part can show the concrete position of dangerous goods on manikin during warning, be convenient to the Security Personnel and search fast.The place that human body privacy position is inconvenient to check directly shows on the human figure in the mode with not invasion of privacy on the display screen especially.
In sum, the utility model be a kind of highly sensitive, check rapidly, avoid the multifunctional human rays safety detection apparatus of violating human rights.
