Abstract

A system comprising: at least one processor; at least one sensor; and computer executable instructions readable by the at least one processor and operative to: use the at least one sensor to determine a number of persons or identity of a person; and trigger an alarm based on the number of persons or the identity of the person. A method comprising: using at least one processor to perform any or all of the following: use at least one sensor to determine a number of persons or identity of a person; and triggering an alarm based on the number of persons or the identity of the person.

Claims

1. A system comprising:

at least one processor;

at least one 3D camera, in communication with the at least one processor; and

computer executable instructions readable by the at least one processor and operative to;

use the at least one 3D camera to visually observe a number of persons in a space, relying on object recognition computer executable instructions to determine a number and/or identity of persons in the space, wherein the object recognition computer executable instructions performs;

image detection in the space, thermal detection in the space, detection of audio of persons in the space, counting the number of persons in the space, and analysis of data captured by the at least one 3D camera;

compare the number of persons that are determined to be in the space with a number of persons authorized to be in the space, wherein the comparison depends on the number of authorized persons that should be in the space as specified by a number stored in a database, wherein the number of persons authorized to be in the space is selected by a user of the system;

trigger an alarm if the number of persons determined to be in the space exceeds or does not correspond to the number of persons authorized to be in the space; and

allow the number of persons authorized to be in the space to be changed if the number of persons in the space does not match or exceeds the number of persons authorized to be in the space.

2. The system of claim 1, wherein the computer executable instructions are operative to receive the number of persons authorized to be in the space from a remote station.

3. The system of claim 1, wherein the 3D camera comprises a time of flight sensor.

4. The system of claim 1, wherein the 3D camera comprises a structured light sensor.

5. The system of claim 1, further comprising a device for identifying a person entering or leaving the space, wherein the device is any one of:

an eye scanner, a face scanner, a finger print scanner, a key reader, a card reader, a smart card reader and wherein the computer executable instructions may be operative to use the device for identifying a person entering or leaving the space to determine the identity of persons in the space, or attempting to enter or leave the space.

6. The system of claim 1, further comprising a device for restricting access to the space wherein the device is any one of:

a door, lock, turnstile, or limited access elevator, wherein the computer executable instructions may be operative to use the device for restricting access to the space to prevent access to the space if the number of persons in the space, or attempting to enter or leave the space exceeds or does not correspond to the number of persons authorized to be in the space.

7. The system of claim 1, further comprising a device for restricting access to the space wherein the device is any one of:

a door, lock, turnstile, or limited access elevator, wherein the computer executable instructions may be operative to use the device for restricting access to the space to allow access to the space if the number of persons in the space, or attempting to enter or leave the space corresponds to or does not exceed the number of persons authorized to be in the space.

8. The system of claim 1, wherein the space comprises a theatre and further comprising a device for restricting access to the theatre wherein the device is any one of:

a door, lock, turnstile, or limited access elevator, and wherein the computer executable instructions may be operative to use the device for restricting access to the theatre to restrict access to the theatre based on the number of persons in the theatre, or attempting to enter or leave the theatre.

9. The system of claim 1, wherein the at least one 3D camera is positioned in a theatre.

10. A method comprising:

using at least one processor to perform the following;

use at least one 3D camera to visually observe a number of persons in a space, relying on object recognition computer executable instructions to determine a number and/or identity of persons in the space, wherein the computer executable instructions performs;

image detection in the space, thermal detection in the space, detection of audio of persons in the space, counting the number of persons in the space, and analysis of data captured by the at least one 3D camera;

compare the number of persons that are determined to be in the space with a number of persons authorized to be in the space, wherein the comparison depends on the number of authorized persons that should be in the space as specified by a number stored in a database, wherein the number of persons authorized to be in the space is selected by a user;

trigger an alarm if the number of persons determined to be in the space exceeds or does not correspond to the number of persons authorized to be in the space; and

allow the number of persons authorized to be in the space to be changed if the number of persons in the space does not match or exceeds the number of persons authorized to be in the space.

11. The method of claim 10, further comprising using the at least one processor to receive the number of persons authorized to be in the space from a remote station.

12. The method of claim 10, wherein the 3D camera comprises a time of flight camera.

13. The method of claim 10, wherein the 3D camera comprises a structured light sensor.

14. The method of claim 10, further comprising the step of using a device for identifying a person entering or leaving the space to determine the identity of persons in the space, or attempting to enter or leave the space wherein the device is any one of:

an eye scanner, a face scanner, a finger print scanner, a key reader, a card reader, a smart card reader.

15. The method of claim 10, further comprising the step of using a device for restricting access to the space, wherein the device is any one of:

a door, lock, turnstile, or limited access elevator and wherein the device is used to prevent access to the space if the number of persons in the space, or attempting to enter or leave the space exceeds or does not correspond to the number of persons authorized to be in the space.

16. The method of claim 10, further comprising the step of using a device for restricting access to the space, wherein the device is any one of:

a door, lock, turnstile, or limited access elevator and wherein the device is used to allow access to the space if the number of persons in the space, or attempting to enter or leave the space corresponds to or does not exceed the number of persons authorized to be in the space.

17. The method of claim 10, wherein the space comprises a theatre, and further comprising the step of using a device for restricting access to the theatre, wherein the device is any one of:

a door, lock, turnstile, or limited access elevator, and wherein the device is used to restrict access to the theatre based on the number of persons in the theatre, or attempting to enter or leave the theatre.

18. The method of claim 10, wherein the at least one 3D camera is positioned in a theatre.
