Abstract

A system provides a collecting growth information of crops in greenhouse. In view of the above, it is possible to estimate the growth and yields of crops depending on the size of the greenhouse and the number of the crops in the greenhouse by collecting growth information of the crops such as plant lengths, leaf areas, internode lengths, fruit color, and the number of fruits of the reference crops.

Claims

1. A system for collecting growth information of crops in a greenhouse, the system comprising:

a first receiving unit configured to receive a first picture that shoots at least one reference crop placed in the greenhouse from a first camera;

a second receiving unit configured to receive a second picture that shoots the reference crop from the first camera and a second camera;

an information acquiring unit configured to acquire at least one piece of growth information of the reference crop from the first and second pictures;

a database unit that stores the acquired growth information; and

an estimating unit configured to estimate growth information of at least one crop group based on the stored growth information.

2. The system of claim 1, wherein the growth information comprises one of a plant length indicative of the length of the reference crop, a leaf area, a fruit color, an internode length, and the number of fruits of the reference crop.

3. The system of claim 1, wherein the reference crop is a sample collection of the crop group.

4. The system of claim 1, further comprising:

at least one light emitting device configured to irradiate light to the reference crop when the first camera or the second camera is operated,

wherein the light emitting device is installed on the opposite side of the reference crop.

5. The system of claim 4, further comprising:

an optical sensor configured to measure an amount of light irradiated to the reference crop; and

an illuminance adjustment unit configured to adjust the illuminance of the light emitting device based on the amount of light measured by the optical sensor,

wherein the optical sensor is installed at a location where the reference drop is placed and is connected with the illuminance adjustment by wires or wirelessly.

6. The system of claim 1, wherein each the first camera or the second camera comprises one of a single camera, a stereo camera and a multi-view camera;

and

the first camera or the second camera shoots a 2D or 3D picture.

7. The system of claim 1, further comprising:

a length measuring device for measuring a length of the reference crop; and

wherein the first camera captures the reference crop including the length measuring device.

8. The system of claim 1, further comprising:

a control unit configured to control the movement of the first camera and the second camera;

the first camera and the second camera communicate with the control unit by wires or wirelessly.

9. The system of claim 1, wherein the estimating unit is configured to estimate at least one piece of growth information among a growth degree, growth stage and yield of the crop group based on the stored growth information.

10. A system for collecting growth information of crops in a greenhouse, the system comprising:

a receiving unit configured to receive a picture that captures at least one reference crop placed in the greenhouse from a camera;

an information acquiring unit configured to acquire at least one piece of growth information of the reference crop from the picture;

a database unit that stores the acquired growth information; and

an estimating unit configured to estimate growth information of at least one crop group based on the stored growth information.

11. The system of claim 10, wherein the growth information comprises one of a plant length indicative of the length of the reference crop, a leaf area, fruit color, an internode length, the number of fruits of the reference crop;

and

the reference crop is a sample collection of the crop group.

12. The system of claim 10, wherein the camera comprises a distance sensor for measuring a distance to the reference crop.

13. The system of claim 10, further comprising:

at least one light emitting device configured to irradiate light to the reference crop when the camera is operated;

an optical sensor configured to measure an amount of light irradiated to the reference crop; and

an illuminance adjustment unit configured to adjust the illuminance of the light emitting device based on the amount of light measured by the optical sensor,

wherein the light emitting device is installed at a location on the opposite side of the reference crop, and

the optical sensor is disposed at a site where the reference crop is placed and is connected with the illuminance adjustment unit by wires or wirelessly.

14. The system of claim 10, wherein the camera comprises one of a single camera, a stereo camera and a multi-view camera;

and

the camera shoots a 2D or 3D picture.

15. The system of claim 10, wherein the estimating unit is configured to estimate at least one piece of growth information among a growth degree, a growth stage, a yield of the crop group based on the stored growth information.
