All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A surveillance system for detecting an illegal object, comprising:
an image-pickup unit for taking an image of a predetermined area;
an object detection unit for detecting information concerning objects pictured in the image on the basis of said image taken by said image-pickup unit;
radio terminal units held by legitimate objects;
radio reception units for receiving signals transmitted by radio from said radio terminal units present in said predetermined area;
a terminal detection unit for detecting information concerning said radio terminal units on the basis of the signals received by said radio reception units; and
an illegal object detection unit for detecting information concerning an illegal object on the basis of the information detected by said object detection unit and the information detected by said terminal detection units.
2. A surveillance system according to claim 1, wherein
said object detection unit detects, as the information concerning the objects, information regarding the number of said objects and positions thereof;
said terminal detection unit detects, as the information concerning the radio terminal units, information regarding the number of said radio terminal units and positions thereof; and
when the number of said objects detected by said object detection unit is larger than the number of said radio terminal units detected by said terminal detection unit, said illegal object detection unit determines as an illegal object an object for which a position of the object detected by said object detection unit does not coincide with a position of a radio terminal unit detected by said terminal detection unit and detects information concerning the illegal object.
3. A surveillance system according to claim 2, wherein said system comprises three or more plural radio reception units and said terminal detection unit detects information regarding positions of said radio terminal units on the basis of signals received by said plural radio reception units.
4. A surveillance system according to claim 2 further comprising an illegality processing apparatus for executing a predetermined process when the presence of said illegal object is detected by said illegal object detection unit.
5. A surveillance system according to claim 2 further comprising a storage unit for storing the correspondence between identification information pieces of radio terminal units legitimate objects hold and information pieces regarding sizes of the legitimate objects, wherein
said object detection unit detects, as the information concerning an object, information regarding the size of the object; and
even when the position of an object coincides with the position of a radio terminal unit, said illegal object detection unit determines the object as an illegal object, on the basis of the information regarding the size of the object detected by said object detection unit and the contents of storage in said storage unit, when the size of said object does not coincide with the size corresponding to the identification information of said radio terminal unit.
6. A surveillance method for detecting an illegal object, comprising the steps of:
taking an image of a predetermined area by means of an image-pickup unit;
detecting, on the basis of the image taken by said image-pickup unit, information inclusive of the number of objects pictured in said image and their positions by means of an object detection unit;
receiving signals transmitted by radio from radio terminal units held by said objects present in said predetermined area by means of radio reception units;
detecting, on the basis of the signals received by said radio reception units, information inclusive of the number of said radio terminal units and positions thereof by means of a terminal detection unit; and
detecting, on the basis of the information detected by said object detection unit and the information detected by said terminal detection unit, information concerning an illegal object by means of an illegal object detection unit.
7. A surveillance method according to claim 6, wherein in the step of detecting information concerning an illegal object, the number of the detected objects is compared with the number of the detected radio terminal units and when the number of the detected objects is larger than the number of the detected radio terminals, the presence of an illegal object is determined, and wherein said surveillance method further comprises the steps of:
collating positions of the objects with positions of the radio terminal units in the image to search an object for which the collation result indicates non-coincidence; and
determining the object for which non-coincident stands to be an illegal object and the position for which non-coincidence stands to be a position of the illegal object.
8. A surveillance method for detecting an illegal object, comprising the steps of:
storing sizes of legitimate objects holding and carrying radio terminal units in a storage unit in advance by making the correspondence between the sizes and pieces of ID data of said radio terminal units;
taking an image of a predetermined area by means of an image-pickup unit;
detecting information inclusive of the number, positions and sizes of objects in the image on the basis of the image taken by said image-pickup unit by means of an object detection unit;
receiving signals transmitted by radio from the radio terminal units held by the objects present in said predetermined area by means of radio reception units;
detecting information inclusive of the number, positions and ID data of the radio terminal units on the basis of the signals received by said radio reception units by means of a terminal detection unit; and
detecting, on the basis of the information detected by said object detection unit and the information detected by said terminal detection unit, information concerning an illegal object by means of an illegal object detection unit.
9. A surveillance method according to claim 8, wherein in the step of detecting information concerning an illegal object, the number of the detected objects is compared with the number of the detected radio terminal units and when the number of the detected objects is equal to or less than the number of the detected radio terminal units, said surveillance methods further comprises the steps of:
taking sizes of legitimate objects holding the radio terminal units out of said storage unit by utilizing the ID data of said detected radio terminal units;
collating sizes of the objects in said image with the sizes, taken out of said storage unit, of the legitimate objects holding the radio terminal units;
comparing the sizes of the objects in said image with the sizes of the objects, taken out of said storage unit, of the objects holding the radio terminal units; and
determining an object for which the comparison result indicates non-coincidence to be an illegal object and an position for which the comparison result indicates non-coincidence to be a position of the illegal object.
