The invention discloses a kind of methods that trailing personnel are identified under the current scene of more people, comprising: carries out Face datection to the video pictures of shooting；Judge in video pictures with the presence or absence of face；If so, extracting the human face data in video pictures；Identification is carried out to the personnel in video pictures according to human face data；Identity information after identification is pushed into display screen；Judge whether the personnel in video pictures have right of access；If it is not, then display screen according to the location of the personnel in video pictures carries out corresponding prompt and guidance to it.The present invention is by carrying out Face datection to the personnel in video pictures, the trailing personnel that not right of access can be effectively prevented enter current gate mouth, and for the mode of this long-range identification face, so that not needing to slow down or stand firm when current in current gate mouth, and then quick passage may be implemented, flexibly and effectively big flow entrance can be managed.
Description
Technical field
The present invention relates to recognition of face, more specifically a kind of side that trailing personnel are identified under the current scene of more people
Method.
Background technique
The logic that is commonly designed of the current security system of personnel is: current door default is closed, and ordinary person is impassable.When having
After the people of right of access is authenticated by modes such as recognition of face, two dimensional code, IC card, current door is let pass.
But such operation is in the presence of the security risk that can not identify " trailing " behavior: after i.e. someone passes through authentication, without logical
The people of row permission can trail the people by gate inhibition, system trailing personnel can not timely be identified, be prompted, being guided or
Warning.
Summary of the invention
It is identified under the current scene of more people it is an object of the invention to overcome the deficiencies of the prior art and provide one kind and trails people
The method of member.
To achieve the above object, the invention adopts the following technical scheme: people is trailed in a kind of identification under the current scene of more people
The method of member, which comprises
Face datection is carried out to the video pictures of shooting；
Judge in video pictures with the presence or absence of face；
If so, extracting the human face data in video pictures；
Identification is carried out to the personnel in video pictures according to human face data；
Identity information after identification is pushed into display screen；
Judge whether the personnel in video pictures have right of access；
If it is not, then display screen according to the location of the personnel in video pictures carries out corresponding prompt and guidance to it.
Its further technical solution are as follows: whether there is face step in the judgement video pictures, specifically include following
Step:
Video pictures are filtered；
Judge whether to obtain face feature point from filtering, wherein face feature point include face contour, eyebrow, nose,
Eyes and lip；
If so, obtaining the position of face feature point；
The position of face feature point and average characteristics face are compared；
Judge whether comparing result meets threshold requirement；
If so, can determine that is a face.
Its further technical solution are as follows: the human face data step extracted in video pictures specifically includes following step
It is rapid:
Cut all people's face region picture in video pictures；
Extract face recognition features' point in human face region picture；
Characteristic value calculating is carried out to face recognition features' point.
Its further technical solution are as follows: described that identification step is carried out to the personnel in video pictures according to human face data
Suddenly, specifically includes the following steps:
Access white list face information；
Characteristic value and white list face information are compared；
Judge whether the personnel in video pictures are personnel in white list；
If so, transferring the identity information that the personnel in video pictures store in white list, and in marking video picture
Personnel be white list personnel；
If it is not, then intercepting the image of counterpart personnel in video pictures as identity information, and the people in marking video picture
Member is non-white list personnel.
Its further technical solution are as follows: whether the personnel judged in video pictures have right of access step, tool
Body the following steps are included:
Judge whether it is white list personnel；
If so, issuing right of access voucher；
If it is not, then judging whether the personnel in video pictures are disadvantaged group personnel, wherein disadvantaged group personnel include old
People, child, pregnant woman or disabled person；
If so, notifying current gate mouth administrative staff.
Its further technical solution are as follows: the display screen carries out it according to the location of the personnel in video pictures
Corresponding prompt and directing step, specifically includes the following steps:
It obtains according to the location of personnel in video pictures information；
Judge whether the personnel in video pictures enter first area；
If so, display screen plays leading question, the personnel in video pictures is guided to register or leave；
If it is not, then judging whether the personnel in video pictures enter second area；
If so, display screen carries out voice warning, while warning message is pushed to Security Personnel.
Its further technical solution are as follows: the first area is warning zone, and the second area is expulsion region；It is described
The distance between region and current gate mouth is expelled to be less than the distance between the warning zone and current gate mouth.
Compared with the prior art, the invention has the advantages that: one kind provided by the invention identifies under the current scene of more people
The method of trailing personnel can be effectively prevented no right of access by carrying out Face datection to the personnel in video pictures
Trailing personnel enter current gate mouth, and for the mode of this long-range identification face, so that not needing to subtract when current
Speed is stood firm in current gate mouth, and then quick passage may be implemented, can flexibly and effectively to big flow entrance into
Row management.In addition, entrance can be reduced to the people of Security Personnel by identification, guidance, alarm to no right of access personnel
Force request, to reduce costs.
The above description is only an overview of the technical scheme of the present invention, can in order to better understand technical measure
It is implemented in accordance with the contents of the specification, and in order to make above and other objects of the present invention, feature and advantage brighter
Show understandable, special below to lift preferred embodiment, detailed description are as follows.
