Fig. 1 is a flow diagram of a security inspection method according to an exemplary embodiment of the present disclosure.

The disclosure provides a security inspection method applied to security inspection equipment for centralized graph judgment, as shown in fig. 1, comprising the following steps: a plurality of articles to be scanned, such as a backpack, a trunk, etc., are sequentially scanned by a scanning unit to perform, for example, an X-ray based radiation inspection; the scanned objects enter a graph judging area in sequence to wait for graph judgment, the scanned object images are transmitted to a central control room or an upper computer to conduct centralized graph judgment, namely, whether scanned objects exist in the scanned objects or not is judged manually or not based on the object scanned image computer, the graph judging area comprises a plurality of graph judging positions which are sequentially arranged in the moving direction of the objects, so that a plurality of scanned objects are stored in the graph judging area, wherein the last graph judging position in the moving direction is a waiting position; dividing each article into a normal article or a suspicious article according to the judgment result; and the normal articles pass through the waiting position without stopping and enter the fetching area so as to be fetched; in the case where the suspicious object is moved to the waiting position, the suspicious object stays in the waiting position until the suspicious object is taken out from the waiting position.

In an exemplary embodiment, the scanning unit comprises an X-ray based imaging device adapted for checking whether contraband such as drugs, explosives are present in objects such as luggage, packages, handbags, etc. in places where personnel mobility is great, such as stations, airports, stadiums, malls, etc. The scanning unit mainly includes: support frame, transmission mechanism, and actuating mechanism. An inspection space adapted to inspect an object is formed in the support frame, the inspection space having a first opening communicating with the outside. The support frame is provided with a housing made of a shielding material to prevent radiation leakage. The transport mechanism is adapted to carry the object for movement through the examination space. An X-ray emitting and receiving device such as a CT machine is mounted on the support frame to perform an X-ray scanning examination of an object transported to the examination space by the transport mechanism.

According to the security inspection method of the embodiment of the invention, each article passing through the scanning unit is divided into a normal article or a suspicious article according to the image judgment result, and all scanned articles are firstly conveyed to a plurality of image judgment positions capable of storing a plurality of articles, and the image judgment result is waited. The normal articles pass through the image judging area to be taken away, and the suspicious articles are conveyed to a waiting position to wait for subsequent processing. On the basis of not adding a conveying channel and adding a functional area, the working state of the graph judging position is adjusted to realize the differentiated treatment of different articles so as to meet the requirements of security inspection equipment with a centralized graph judging function.

In an exemplary embodiment, a map determining area is provided downstream of the scanning unit, in which three map determining positions are provided. Thus, the image of three articles can be judged at most simultaneously. It should be understood that embodiments of the present disclosure are not limited thereto.

For example, the number of map positions also includes two, four, five, and other numbers. The specific number can be adaptively designed according to the space of the specific application scene. For example, each decision region holds one scanned item.

In an exemplary embodiment, normal items are characterized as items that meet security standards, suspicious items are characterized as items or other items contained in items that do not meet security standards, and a manual inspection should be performed.

In another illustrative embodiment, a normal item is characterized as one type of item and a suspicious item is characterized as another type or types of items (other items than the normal item).

In an exemplary embodiment, the waiting position is characterized as a map position furthest from the scanning unit. Thus, when the suspicious object stays at the image judging position far away from the scanning unit to wait for the operator to take the suspicious object off, other image judging positions can still transmit other objects to pass or wait for image judging. It should be understood that embodiments of the present disclosure are not limited thereto. By setting the waiting position it is ensured that the suspicious item will be brought to the attention of the operator and will not be transported to the next station to be taken away by the controller (or owner) of the item.

For example, the waiting position may be set as the last few map judgment positions. Thus, when a plurality of suspicious articles are continuously arranged, each suspicious article can stay at the corresponding graph judging position to wait for the operator to take down. It should be understood that embodiments of the present disclosure are not limited thereto.

For example, the waiting position may also be located near the scanning unit or any other decision making position or positions for holding the suspicious object and waiting for subsequent processing by the operator.

According to the embodiment of the disclosure, the security inspection method further comprises the step of taking off the suspicious object or waiting for the suspicious object at the waiting position to be taken off and then moving and staying at the waiting position if the suspicious object exists in the rest of the graph judging positions under the condition that the suspicious object is at the waiting position.

According to an embodiment of the present disclosure, the security inspection method further includes: and positioning the map judging position where the suspicious object is located. Such as displaying the sequence number of the graph judgment position, sending out voice warning, etc.

According to an embodiment of the present disclosure, locating a map location where a suspicious object is located includes: identifying the initial graph judging position where the suspicious object stays; and tracking each graph judging position passed by the suspicious object until the suspicious object stays at the waiting position. Therefore, before the suspicious object stays at the waiting position, operators can find and track the suspicious object so as to shorten the time for taking down the suspicious object by the operators, and the method is favorable for carrying out coherent and faster security check on other objects.

In one illustrative embodiment, identification and tracking of suspicious items is disclosed. The disclosure is characterized in that other personnel in the security check place can know the condition of suspicious articles. For example, by audio or visual alerting.

In another illustrative embodiment, identification and tracking of suspicious items is not disclosed, which is characterized by the fact that other personnel located in the security facility are not aware of the presence of suspicious items, except for operators with corresponding rights. For example, the information containing the suspicious object is sent to the mobile phone or the operation terminal of the operator.

According to an embodiment of the present disclosure, locating the map-determining position where the suspicious object is located further includes performing a visualization process on the map-determining position.

In one illustrative embodiment, the visualization process is characterized by a more intuitive notification to the operator of the location of the decision map where the suspicious item is located.

In detail, the visualization process includes, but is not limited to, audio, video and vibration representation of the map location where the suspicious object is located.
