Detailed Description

The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.

A face recognition and RFID-based airport passenger hand-held baggage tracking and checking method is characterized in that image data of passenger hand-held baggage in a security check passage are automatically corresponding to passenger information through the face recognition and the RFID, and passengers can conveniently search and check back after the package is opened. Specifically, the method comprises the following steps:

step S1: the security check verifies the passenger information, and the face photos are collected and registered to a database;

step S2: under the condition that the hand luggage is put in the luggage frame, the RFID radio frequency code reader reads the RFID label of the luggage frame, and after the reading is successful, the face recognition is started;

step S3: the shot passenger scene photo is compared with a registered face photo database when the passenger passes the security check verification, and the best matched passenger information is obtained and is associated with the RFID label;

step S5: after the hand-held luggage image is judged, if the luggage image is normal, the luggage is conveyed to the safe luggage channel, and if the luggage image is abnormal, the luggage is conveyed to the suspicious luggage channel for safety inspection.

In order to implement the method, the airport passenger portable luggage tracking and checking system based on face recognition and RFID mainly comprises:

the security check verification subsystem:

the method is used for collecting the on-site photos of the passengers, and can verify the legality of the flight status, the luggage status and the identity information of the passengers according to certain rules, so as to carry out passing or interception. If the passenger security check is verified to be normal, recording information such as passenger release state, security check time, security check channels, security check personnel and the like, registering the collected face photos and the passenger information into a face recognition database of a face recognition subsystem according to the security check channels, releasing passengers, and entering the security check channels; if the passenger security check is abnormal, recording the information of the passenger interception state, the security check time, the security check passage, the security check personnel and the like, and intercepting the passenger.

For cleared passengers, the security verification subsystem may send out a clear message every time a passenger is cleared. The clearance message includes the passenger identification, the security screening channel number, and the passenger's live photograph. The passenger identification can adopt a unique identification consisting of a passenger flight number, a flight date, an origin station and a boarding number, the passenger identification is required to uniquely confirm a passenger, sensitive information such as a passenger name, an identity document number and the like can be searched according to the passenger identification in the system, and meanwhile, the sensitive identity information of the passenger is not leaked in other external systems. The messages may be sent via an MQ, such as a RabbitMQ or an ActiveMQ, so that the messages may be sent to multiple systems, including external systems, without modifying the code, thereby achieving decoupling of the systems. The security check channel number is used for isolation when registering face recognition service, namely, passengers passing through the channel A can only register to the face recognition database corresponding to the channel A partition, and the passengers of the channel A only need to compare in the face recognition database corresponding to the channel A partition when carrying out 1 to N face recognition. The realization of the method avoids the possibility that passengers in other channels are identified when the face identification is carried out by comparing 1 to N by the passengers in the channel A, and meanwhile, the passengers in all channels do not need to be searched, and only the passengers in the current channel need to be searched and compared, so that the calculation engineering quantity can be greatly reduced, and the efficiency is improved. The passenger scene photo is used for registering in the face recognition subsystem, and the face recognition subsystem extracts and stores the face features in the photo for face comparison at a luggage workbench in the channel. The security inspection requires that the on-site photos of passengers are clear and have no occlusion, so the security inspection verification subsystem needs to integrate the face detection SDK and obtain clear, reliable and non-occlusion face photos through a face detection algorithm.

Face recognition subsystem:

the method is used for detecting the face of a passenger on site and acquiring a face image, for example, the face recognition is carried out in a 1 to N mode; and the face recognition database is responsible for maintaining, registered faces can be logged out of the database according to a certain timeout time, the timeout time can be preferably 20 minutes generally, and other times can also be used.

The face recognition service manufacturer can select the mature solution provided by companies such as iridescent technology or Baidu technology. Face detection should be able to detect face occlusion, whether a face is frontal, and return the highest rated face picture within a reasonable time frame (usually 3-7 seconds). When a photograph contains multiple faces, the largest one, i.e. the one positioned most forward, is usually selected due to the requirement for queuing at the time of security inspection. The face detection is usually integrated into a client in an off-line SDK mode, a camera is usually integrated on a screen of a passenger side according to a vertical screen of about 10 inches, and a screen picture is used for feeding back a real-time image of the camera and a related prompt of the face detection to prompt the passenger to take a picture. When the face recognition subsystem receives the passenger screening information, the face features are extracted from the passenger screening pictures, and the passenger identification and the face features are registered in the face recognition database according to the passenger channel number. When a passenger enters a security check channel, the luggage frame is taken and placed on a luggage workbench (as shown in fig. 2 and fig. 3), an RFID radio frequency card reader on the luggage workbench reads an RFID number on the luggage frame and informs a front-end device through an RS2312 serial port, the front-end device can select a porphyrizing industrial personal computer in the channel, a face recognition screen is installed in front of each luggage workbench, the front-end device drives the face recognition screen to obtain a face photo in front of the current workbench, 1-to-N face comparison is carried out in a face recognition database registered in the channel, and the highest comparison score is selected. The face recognition database is responsible for maintaining face feature data of each channel according to the channel number, and the face feature data comprises registered faces and unregistered faces. When the passenger passes the security check verification, the security check verification subsystem sends a security check message to the MQ, and the face recognition subsystem receives the security check message from the queue of the MQ to acquire a passenger check photo for face registration. The face logout is carried out at the place of the X-ray machine, the RFID radio frequency device reads the RFID number, the corresponding passenger identification is obtained according to the RFID number, and the passenger face photo is logout from the face recognition database through the passenger identification. After logout, the luggage frame corresponding to the RFID electronic tag can be repeatedly used, and can be recycled on the luggage workbench again. The face logout also has a plurality of compensation measures, such as a compensation scheme I, when the face is registered, a proper expiration time is arranged, for example, the face logout is performed from the face recognition database after 20 minutes, namely, the passenger security check process can be guaranteed to be completed within 20 minutes. And in the second compensation scheme, the number of passengers in the channel is considered, 1 is added to the number of the passengers in the channel when the faces are registered, 1 is subtracted from the number of the passengers in the channel when the faces are cancelled, and the passengers initially registered are cancelled when the number of the passengers in the channel exceeds 15, namely the number of the passengers in the normal channel cannot exceed 15.
