Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
Referring to fig. 1, a method for intercepting a baggage pre-inspection risk according to an embodiment of the present application will now be described. The luggage pre-inspection risk interception method comprises the following steps:
step S1, pre-checking luggage and marking risk luggage;
s2, tracking and positioning the baggage and generating a real-time motion trail of the baggage;
step S3, carrying out risk association on the baggage and the passenger when the baggage is extracted;
and S4, intercepting the risk baggage and the risk passenger in the risk interception channel.
It will be appreciated that referring to fig. 1 to 5, in step S1, before a passenger enters a hall, the baggage is pre-checked in advance, the baggage pre-checking method includes that the passenger places the baggage in an upper baggage area of a baggage conveyor belt, an inductive power-off 10, a camera 20, an X-ray machine 30 and a sealing device 40 are arranged on the baggage conveyor belt, the inductive power-off 10 can monitor a conveying position of the baggage, the camera can record an image of each baggage, the X-ray machine can check the interior of the baggage, the baggage with abnormal baggage transmission or abnormal inspection by the X-ray machine is marked as a risk baggage, and the sealing device can seal a positioning card by using an adhesive tape or directly seal a positioning lock to realize tracking and positioning of the baggage.
It will be appreciated that the pre-screening action described above is performed for each baggage, so that the marking, tracking and locating of the risky baggage for the passenger is performed under hidden conditions, so that psychological stress is not generated for normal passengers, and the risky passengers are not perceived, reducing their vigilance.
In step S2-S3, after the sealing of the baggage is completed, the baggage can be tracked and positioned, a real-time movement track of the baggage is generated, the baggage can enter a baggage extracting area before the baggage is extracted, the baggage can be extracted by passengers in the area, the baggage extracted is not required, and the baggage can be circularly moved through an extracting turntable until the baggage is extracted.
Because the passengers cannot be tracked and positioned, the passengers can be tracked only through the baggage, the baggage can be intentionally exchanged after the baggage is pre-checked in order to avoid the situation of partner, or the baggage can be maliciously carried out by the passengers, and the baggage and the passengers are subjected to risk association when the baggage is extracted, so that the real association relationship can be obtained.
In step S4, the risk interception channel may set an area from which an alarm can be intercepted at a certain distance from the channel entrance. The personnel can check the baggage conveniently. The passageway mentioned here can set up the passageway of two gates, and the passenger gets into the entry gate after, and the entry gate is closed, and the passenger only need brush the export gate and can open behind the evidence piece, and the passenger is in the middle of the two gates this moment. The risk baggage and the risk passengers can be intercepted at the risk interception channel, so that the interception success rate is improved.
Compared with the prior art, the method for intercepting the risk of the baggage pre-inspection, provided by the application, has the advantages that the baggage pre-inspection is carried out, the risk baggage is marked, the baggage is tracked and positioned, the real-time motion trail of the baggage is generated, the baggage and the passenger are subjected to risk association, the synchronous interception of the risk baggage and the risk passenger is realized, and the safety risk of public places and the success rate of risk interception are improved.
In another embodiment of the present application, referring to fig. 6, in step S2, a method for tracking and positioning baggage includes:
applying a positioning unit to the baggage;
the vibration sensing system of the positioning unit wakes up the positioning unit, and the positioning unit sends active positioning information to the background monitoring system through the active positioning unit;
the background monitoring system sends an instruction to the positioning unit when passive positioning information of the positioning unit is not acquired within a time threshold T after active positioning information is received;
after receiving the instruction, the positioning unit sends active positioning information to the background monitoring system through the active positioning unit.
It will be appreciated that the locating unit may be built into a luggage sealing locating lock or card, which has a concealed and non-removable feature. When a passenger takes a rest in a hall, the luggage keeps still, the positioning unit keeps dormant, the vibration sensing system can sense vibration when the passenger drags the luggage to move, the positioning unit is awakened, the positioning unit sends active positioning information to the background monitoring system through the active positioning unit, the active positioning unit can be a GPS unit, but the background monitoring system only needs to know that the luggage is in the hall and starts to move through the active positioning information, the specific position of the luggage mainly passes through the passive positioning of the positioning unit, the positioning signal emission source in the hall sends positioning signals, for example, through the RFID identification device arranged in the hall, if the passenger carries the luggage to move in the hall, the RFID tag in the positioning unit can trigger different RFID identification devices in sequence along the way, the background monitoring system acquires the passive positioning information of the positioning unit, and does not send instructions to the positioning unit in the monitoring range; if the background monitoring system does not acquire the passive positioning information of the positioning unit within the range of the time threshold T after receiving the active positioning information, the background monitoring system indicates that the luggage is moving, but the luggage possibly escapes from the monitoring range, the background monitoring system sends an instruction to the positioning unit, and after receiving the instruction, the positioning unit sends the active positioning information to the background monitoring system through the active positioning unit, and the position of the luggage is determined again, if the escape phenomenon is confirmed, the luggage is detected at the first time.
Further, in step S2, after the vibration sensing system of the positioning unit wakes up the positioning unit, the method includes the steps of:
after the positioning unit sets an automatic wake-up clock of a time threshold T, the positioning unit enters a sleep state again, and the positioning unit cannot be repeatedly awakened by the vibration sensing system within the range of the time threshold T;
and after the time threshold value T is reached, the clock is automatically awakened to wake up the positioning unit, and the instruction of the background monitoring system is waited to be received.
It can be understood that the positioning unit enters the deep sleep state again after setting the automatic wake-up clock of the time threshold T, so that the power consumption can be saved during the sleep state, and the vibration sensing system cannot wake up repeatedly within the time threshold T. However, when the time threshold T is reached, the clock needs to be automatically awakened to wake up the positioning unit, and the instruction of the background monitoring system is waited to be received. Preferably, if the positioning unit waits for more than 2S, it enters the sleep state again. If the instruction is received in the waiting period of the positioning unit, the active positioning information is sent to the background monitoring system through the active positioning unit, the background monitoring system positions the active positioning information to judge the luggage position, and the passenger behavior is analyzed. In this way, the total time during the two wake-up states in the whole process does not exceed 5S, and the power consumption of the positioning unit is further saved.
Further, referring to fig. 7, the method for generating a real-time motion trajectory of baggage includes:
and performing curve fitting on the passive positioning information and the active positioning information according to the receiving time to generate a real-time motion track of the luggage.
It can be understood that by performing curve fitting on passive positioning information and active positioning information according to the receiving time, a real-time motion track of the baggage is generated, whether the behaviors of the baggage and the passenger are in an expected range can be monitored, and the real-time motion track is abnormal and can be intercepted in advance.
In another embodiment of the present application, referring to fig. 8, in step S3, a method for associating a baggage with a passenger at risk during baggage retrieval includes:
acquiring a face image of a passenger when the passenger extracts the luggage;
associating the passenger with the baggage;
if the baggage is marked as a risky baggage, the passenger is marked as a risky passenger.
It will be appreciated that since the baggage has been tracked prior to the passenger picking up the baggage, the passenger may be associated with the baggage by acquiring an image of the passenger's face as the passenger picks up the baggage, enabling a risk association of the baggage with the passenger.
Further, referring to fig. 8, in step S3, the method for associating the baggage with the passenger when the baggage is fetched further includes:
when a passenger places luggage, a passenger bending placement action image and a face image are obtained in advance;
when a passenger extracts luggage, obtaining a passenger bending extraction action image and a face image;
if the action image recognition or the face image recognition of the same baggage is not consistent with the extraction, the baggage and the passengers when the baggage is extracted are marked as risk baggage and risk passengers.
It can be understood that, since the passengers can track the baggage after placing the baggage on the conveyor belt under the action of the photoelectric or camera, the passengers maliciously picking up the baggage of other people or the passengers in combination with the crime to evade the tracking can be found by judging whether the action image recognition or the face image recognition of the baggage is consistent with the action image recognition of picking up the same baggage. Because of the action habit and human skeleton difference of each person, different passengers can enlarge the action gesture characteristics when bending down, which is beneficial to the accuracy of the identification of the action images.
Further, referring to fig. 8, in step S3, the passenger bending action image is the last frame image of the passenger finger separated from the baggage, and the passenger bending extraction action image is the first frame image of the passenger finger contacting the baggage.
It can be understood that the last frame of image of the separation of the passenger finger and the luggage and the first frame of image of the contact of the passenger finger and the luggage are in the unstressed state, and the action gesture of the same passenger under the two conditions is closest, so that the accuracy of the identification of the action image is further improved.
Further, in step S3, before the passenger extracts baggage, the method includes the steps of:
the baggage is spatially adjusted such that the spatial direction when the baggage is placed coincides with the spatial direction when the baggage is retrieved.
It can be understood that, in order to further improve the accuracy of motion image recognition, space adjustment is also performed on the baggage, for example, a rotating disc is provided on the conveyor belt, so that the space direction when the baggage is placed is consistent with the space direction when the baggage is extracted, the height of the baggage relative to the ground is also kept consistent, and the shooting angle of the camera is also kept consistent.
Further, referring to fig. 5, in step S4, a method for intercepting at-risk baggage and at-risk passengers in a at-risk interception channel includes:
after the passengers and the baggage enter the risk interception channel, face images and baggage IDs are identified, the risk baggage and the risk passengers marked as risk are intercepted, and whether the risk is true is verified.
It can be understood that the baggage ID can be sensed by the RFID recognition sensing device disposed in the risk interception channel, and the face image can be recognized by the face recognition device on the exit gate of the risk interception channel, and if the risk baggage or the risk passenger is determined, the risk baggage or the risk passenger is intercepted, and the security check personnel check the risk baggage or the risk passenger.
Further, in step S4, if the risk is verified, the baggage with the same movement track is matched, and the baggage is marked as a risk baggage, and the passenger who has picked up the baggage is marked as a risk passenger.
It can be understood that, in order to solve the problem of evading and tracking of the partner cases, the partner members of the same party can be found by matching the baggage with the same movement track, so that the security risk and the success rate of risk interception in public places are further improved. It should be noted that matching the same motion trajectory should include a time dimension, for example, the same motion trajectory formed by two passengers at different times or at larger time intervals, not the same motion trajectory. Of course, the same motion track may be that the matching rate of a certain period exceeds the matching threshold, and cannot be understood as the whole track or the track is identical.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the application.
