Surveillance system and surveillance method

1. A surveillance system comprising:

a control tower configured to be coupled with and separated from a flying vehicle, and receive an image captured by the flying vehicle through a first communication network,

wherein the control tower is further configured to transmit the received image to a central control station through a second communication network for analysis of the received image,

wherein the control tower comprises:

an image capturer configured to capture an image of the flying vehicle; and

a landing guide configured to generate a landing guide signal based on the image obtained by the image capturer, and

wherein the landing guide generates a landing guide signal by:

capturing a first image of the flying vehicle by using the image capturer;

comparing the first image with a pre-stored image to determine an amount of horizontal movement for the flying vehicle to generate and giving a command to horizontally move the flying vehicle based on the determined amount of horizontal movement;

capturing a second image of the flying vehicle by using the image capturer;

comparing the second image with the pre-stored image to determine an amount of vertical movement for the flying vehicle to generate and giving a command to vertically move the flying vehicle based on the determined amount of vertical movement; and

determining an amount of altitude loss for the flying vehicle to generate and giving a command to the flying vehicle to lose altitude based on the determined amount of altitude loss.

2. The surveillance system of claim 1 , wherein the first communication network is a short-range wireless communication network, and the second communication network is a long-range wired and/or wireless communication network.

3. The surveillance system of claim 1 , wherein the control tower comprises:

a mounting portion with which the flying vehicle is configured to be coupled; and

a power supply configured to supply power to the flying vehicle when the flying vehicle is coupled with the control tower.

4. The surveillance system of claim 1 , further comprising the flying vehicle and the central control station.

5. The surveillance system of claim 4 , wherein the flying vehicle comprises:

a global positioning system (GPS) receiver configured to receive position information about the flying vehicle;

a battery configured to supply power to the flying vehicle; and

a controller configured to control an operation of the flying vehicle,

wherein the controller comprises a program whereby the flying vehicle returns to the control tower based on a remaining amount of the power and the position information.

6. A surveillance system comprising:

a control tower configured to be coupled with and separated from a flying vehicle installed with a camera,

wherein the control tower comprises:

an image capturer configured to capture an image of the flying vehicle;

a power supply configured to supply power to the flying vehicle when the control tower is coupled with the flying vehicle; and

a landing guide configured to generate a landing guide signal based on the captured image of the flying vehicle, and

wherein the landing guide generates a landing guide signal by:

capturing a first image of the flying vehicle by using the image capturer;

comparing the first image with a pre-stored image to determine an amount of horizontal movement for the flying vehicle to generate and giving a command to horizontally move the flying vehicle based on the determined amount of horizontal movement;

capturing a second image of the flying vehicle by using the image capturer;

comparing the second image with the pre-stored image to determine an amount of vertical movement of the flying vehicle and giving a command to vertically move the flying vehicle based on the determined amount of vertical movement; and

determining an amount of altitude loss for the flying vehicle to generate and giving a command to the flying vehicle to lose altitude based on the determined amount of altitude loss.

7. The surveillance system of claim 6 further comprising the flying vehicle.

8. The surveillance system of claim 7 , wherein the flying vehicle comprises:

a global positioning system (GPS) receiver configured to receive position information about the flying vehicle;

a battery configured to supply power to the flying vehicle; and

a controller configured to control an operation of the flying vehicle,

wherein the controller comprises a program whereby the flying vehicle returns to the control tower based on a remaining amount of power at the battery and the position information.

9. A surveillance method comprising:

capturing an endurance surveillance image of a flying vehicle;

transmitting the captured endurance surveillance image to a central control station via a control tower disposed adjacent to the flying vehicle;

comparing a remaining amount of power at a battery of the flying vehicle with a standard remaining amount of power; and

if the remaining amount of power at the battery is less than the standard remaining amount of power, landing the flying vehicle on the control tower based on a landing guide signal of the control tower,

wherein the landing guide signal is generated by:

capturing a first image of the flying vehicle by an image capturer of the control tower;

comparing the captured first image with a pre-stored image to determine an amount of horizontal movement for the flying vehicle to generate and giving a command to horizontally move the flying vehicle based on the determined amount of horizontal movement;

capturing a second image of the flying vehicle by using the image capturer;

comparing the second image with the pre-stored image to determine an amount of vertical movement for the flying vehicle to generate and giving a command to vertically move the flying vehicle based on the determined amount of vertical movement; and

determining an amount of altitude loss for the flying vehicle to generate and giving a command to the flying vehicle to lose altitude based on the determined amount of altitude loss.

10. The surveillance method of claim 9 , further comprising charging the battery of the flying vehicle after the flying vehicle has landed on the control tower.

11. The surveillance method of claim 9 , further comprising:

capturing a fixed surveillance image using the flying vehicle after the flying vehicle has landed on the control tower; and

transmitting the captured fixed surveillance image to the central control station via the control tower.

12. The surveillance method of claim 9 , further comprising receiving an endurance command based on a preset program that is set according to a charged state of the battery of the flying vehicle or an endurance command from the central control station.

13. The surveillance method of claim 9 , further comprising:

receiving position information about the flying vehicle;

supplying power to the flying vehicle; and

controlling an operation of the flying vehicle,

wherein the controlling is performed using a program whereby the flying vehicle returns to the control tower based on the remaining amount of power at the battery and the position information.

14. The surveillance method of claim 9 , further comprising:

coupling the flying vehicle with the control tower and separating the flying vehicle from the control tower; and

supplying power to the flying vehicle when the flying vehicle is coupled with the control tower.

15. The surveillance method of claim 9 , further comprising:

capturing an image of the flying vehicle; and

generating a landing guide signal based on the captured image of the flying vehicle.

16. The surveillance method of claim 9 , wherein the captured endurance surveillance image is transmitted from the flying vehicle to the control tower through a first communication network,

wherein the captured endurance surveillance image is transmitted from the control tower to the central control station through a second communication network, and

wherein the first communication network is a short-range wireless communication network, and the second communication network is a long-range wired and/or wireless communication network.
