Abstract

The present disclosure relates to a security check system and method. The present disclosure provides a security check system for identifying objects of interest from multiple objects, comprising: an object-of-interest determining device for determining whether an object is an object of interest; an image mark applying device for acquiring images related to selected objects among the multiple objects and recording image marks of the selected objects; and a mark detecting device for detecting the image marks, wherein the security check system is configured to identify whether the object is the object of interest based on the detection of the mark detecting device and outputs a warning accordingly.

First claim

What is claimed is:

1. A security check system for identifying objects of interest from multiple objects without physical mark, comprising at least a processor operating in conjunction with a memory and a plurality of devices, the devices comprise:
an object-of-interest determining device for determining whether an object is an object of interest based on X-ray scanned images of the object, wherein the object is luggage;
an image mark applying device for acquiring visible, infrared or depth images related to selected objects among the multiple objects through a first camera after the object-of-interest determining device has determined whether the object is the object of interest and recording image marks of the selected objects from the images acquired by the first camera; and
a mark detecting device for acquiring visible, infrared or depth images related to the selected objects through a second camera after the image mark applying device acquires the images related to the selected objects and detecting the image marks from the images acquired by the second camera,
wherein the security check system is configured to identify whether the object is the object of interest based only on the detection of the mark detecting device, without detecting any physical mark, and to output a warning accordingly.

2. The security check system according to claim 1 , wherein
the selected objects comprise at least one of: all objects and objects which are determined to be the objects of interest, and
the security check system is configured to identify whether the object is the object of interest based on the detected image mark and to output a warning if the object is identified as the object of interest based on the image mark.

3. The security check system according to claim 1 , wherein
the image mark is an image feature of the object.

4. The security check system according to claim 1 , wherein
the image mark is an image feature of a person carrying the object.

5. The security check system according to claim 1 , wherein
the image mark applying device is configured to acquire the image related to the object before the object is fetched by a person.

6. The security check system according to claim 1 , wherein
the image mark applying device is configured to acquire the image related to the object when the object is being fetched by a person.

7. The security check system according to claim 5 , wherein
the image mark applying device is configured to acquire at least one of an object image of the object and a person image of the person fetching the object.

8. The security check system according to claim 6 , wherein
the image mark applying device is configured to acquire at least one of an object image of the object and a person image of the person fetching the object.

9. The security check system according to claim 1 , wherein
the selected objects among the multiple objects comprise objects which are determined not to be the objects of interest, and
the mark detecting device is configured to identify the object as the object of interest and output a warning if no recorded image mark is detected.

10. A security check method for identifying objects of interest among multiple objects without physical mark, comprising:
determining whether an object is an object of interest based on X-ray scanned images of the object which are acquired through X-ray scanning, wherein the object is luggage;
acquiring visible, infrared or depth images related to selected objects among the multiple objects through a first camera after it is determined whether the object is the object of interest and recording image marks of the selected objects from the images acquired by the first camera; and
acquiring visible, infrared or depth images related to the selected objects through a second camera and detecting the image marks from the images acquired by the second camera, identifying whether the object is the object of interest based only on the detection of the image mark, without detecting any physical mark, and outputting a warning accordingly.

11. The security check method according to claim 10 , wherein
the selected objects comprise at least one of: all objects and objects which are determined to be the objects of interest, and
it is identified whether the object is the object of interest based on the detected image mark, and wherein a warning is outputted if the object is identified as the object of interest based on the image mark.

12. The security check method according to claim 10 , wherein
the image mark is an image feature of the object.

13. The security check method according to claim 10 , wherein
the image mark is an image feature of a person carrying the object.

14. The security check method according to claim 10 , wherein
the image related to the object is acquired before the object is fetched by a person.

15. The security check method according to claim 10 , wherein
the image related to the object is acquired when the object is being fetched by a person.

16. The security check method according to claim 14 , wherein
the step of acquiring the image related to the object comprises acquiring at least one of an image of the object and an image of the person fetching the object.

17. The security check method according to claim 15 , wherein
the step of acquiring the image related to the object comprises acquiring at least one of an image of the object and an image of the person fetching the object.

18. The security check method according to claim 10 , wherein
the selected objects among the multiple objects comprise objects which are determined not to be the objects of interest, and
the object is identified as the object of interest and a warning is outputted if no recorded image mark is detected.

19. A security check system for identifying objects of interest from multiple objects, comprising:
a processor; and
a memory for storing instructions executable by the processor,
wherein the processor is configured to:
determine whether an object is an object of interest based on X-ray scanned images of the object which are acquired through X-ray scanning, wherein the object is luggage;
acquire visible, infrared or depth images related to selected objects among the multiple objects through a first camera after it is determined whether the object is the object of interest and record image marks of the selected objects from the images acquired by the first camera; and
acquire visible, infrared or depth images related to the selected objects through a second camera and detect the image marks from the images acquired by the second camera; and

identify whether the object is the object of interest based only on the detection of the image mark, without detecting any physical mark, and output a warning accordingly.
