Abstract

The objective of the present invention is to provide a poultry weight measurement and weight estimation system, which can estimate weight by considering the unique size of each poultry individual and does not interrupt the transit of poultry. To accomplish the objective, the poultry weight measurement and weight estimation system according to the present invention can comprise: a rotary part which is connected to a motor and rotates and which has a wire wound thereon or unwound therefrom; a measurement unit which is connected to the wire and on which poultry can be placed; a scale unit for measuring the weight of poultry placed on the measurement unit; a camera unit for capturing an image of the top of the measurement unit; and a control unit which controls the motor so that the wire is wound on or unwound from the rotary part, and thus adjusts ascending and descending of the measurement unit, which receives information about the weight measured by the scale unit and information about the image captured by the camera to calculate the per-pixel weight of the poultry on the inner side of the measurement unit, and which estimates the per-pixel weight of the poultry on the outer side of the measurement unit on the basis of the calculation result.

Claims (24)

1 . A poultry weight measurement and weight estimation system, characterized by comprising:

a rotary unit which rotates while being connected to a motor, and has a wire wound thereon or unwound therefrom;

a measurement unit which is connected to the wire and on which poultry can be placed;

a scale unit for measuring the weight of poultry placed on the measurement unit;

a camera unit for taking an image of the top of the measurement unit; and

a control unit which controls the motor so that the wire is wound on or unwound from the rotary unit, and thus adjusts ascending and descending (or lifting and lowering) of the measurement unit, which receives information on the weight measured by the scale unit and information on the image taken by the camera unit to calculate a weight per pixel (“per-pixel weight”) of the poultry inside the measurement unit, and which estimates a per-pixel weight of the poultry outside the measurement unit on the basis of the above calculated value,

wherein the system is characterized in that it further comprises: a triangular panel unit, in which an upper edge is fixed to the lower portion of the measurement unit over the entire length direction of the measurement unit and which has a predetermined height, and

wherein the control unit designates an area formed around the periphery of the triangular panel as an inside of the measurement unit and designates an outside of the above area formed around the periphery of the triangular panel as an outside of the measurement unit, so as to distinguish the above inside and outside of the measurement unit from each other.

2 . The system according to claim 1 , wherein the system is characterized in that it further comprises a pair of connectors, of which one end of each connector is connected to the rotary unit while the other end thereof is connected to one side and the other side of the measurement unit.

3 . The system according to claim 2 , wherein the pair of connectors have a length-adjustable configuration and consist of multi-stage rods, slidable poles or link connection members.

4 . The system according to claim 2 , wherein the pair of connectors further include fixtures to connect the pair of connectors to each other, and

the camera unit is connected to the fixtures.

5 . The system according to claim 4 , wherein each of the pair of connectors includes:

an upper connecting stage positioned on an upper portion; and

a lower connecting stage positioned on a lower portion, which is directly or indirectly connected to the upper connecting stage, and to which the measurement unit is connected.

6 . The system according to claim 5 , wherein the scale unit is provided between a pair of upper connecting stages and a pair of lower connecting stages, respectively, and measures the weight applied to the measurement unit.

7 . The system according to claim 5 , wherein the fixture includes:

a first fixing stage formed at a lower end of the upper connecting stage; and

a second fixing stage formed at an upper end of the lower connecting stage.

8 . The system according to claim 7 , wherein the camera unit is provided on the second fixing stage, and

the scale unit is provided between the first fixing stage and the second fixing stage, so as to measure the weight applied to the measurement unit connected to the lower connecting stage.

9 . The system according to claim 1 , wherein the system is characterized in that it further comprises: a distance sensor for measuring a distance between the measurement unit and the ground.

10 . The system according to claim 9 , wherein the control unit calculates a per-pixel weight of the poultry inside the measurement unit on the basis of a distance between the camera unit and the pre-designated measurement unit, and calculates a per-pixel weight of the poultry outside the measurement unit on the basis of a distance between the camera unit and the ground so as to, estimate the weight per individual of the poultry outside the measurement unit.

11 . The system according to claim 1 , wherein the system is characterized in that it further comprises: an external camera for photographing an area not overlapping the area taken by the camera unit.
