(Embodiment 1)
[Constitution]
Hereinafter, the animal identification member according to the first embodiment will be described. FIG. 1 is a diagram showing an example of use of the animal identification member according to the first embodiment.

The animal individual identification member 10 is, for example, a disk-shaped identification tag used for identifying a plurality of pigs 70 individuals kept in a pig bunch. As shown in FIG. 1, the animal identification member 10 is attached to the ear of the pig 70. 2A and 2B are perspective views of the individual identification member 10 for animals, FIG. 3A is a plan view of the individual identification member 10 for animals, and FIG. 3B is an individual identification member 10 for animals. It is a cross-sectional view of.

Specifically, the animal individual identification member 10 includes a base material 11, an identification unit 12, a connecting member 13, and a stopper 14.

The base material 11 is a disk-shaped member. The base material 11 is mainly formed of a polyurethane resin (polyurethane elastomer). The base material 11 is flexible and can be bent to some extent with bare hands. The base material 11 has a first main surface 11a in contact with the body surface of the pig 70, and a second main surface 11b opposite to the first main surface 11a (that is, facing back to the first main surface 11a). .. An identification unit 12 is provided on the second main surface 11b of the base material 11.

The identification unit 12 is a portion that constitutes a so-called color code. That is, the identification unit 12 indicates the identification information of the pig 70 by arranging a plurality of colors. If the identification unit 12 is imaged by a camera (imaging unit), the image processing of the captured image can identify the identification information of the pig 70. The identification unit 12 is printed on, for example, the second main surface 11b of the base material 11, but the members constituting the identification unit 12 may be adhered to the second main surface 11b of the base material 11.

In the individual identification member 10 for animals, the identification unit 12 arranges a plurality of different colors (for example, three colors of R (red), G (green), and B (blue)) except white and black, and the pig 70 Identification information (in other words, ID) is shown. In the color code, the bit value is determined by the adjacent colors. For example, when adjacent colors change from red to blue, blue to green, and green to red in the color code, the bit is "1" and the adjacent colors are from red to green, green to blue, and blue. Rules for recognizing a color code as digital data, such as a bit being "0" when each changes to red, are predetermined.

The color used for the identification unit 12 may be different from the color of the second main surface 11b, and is not particularly limited. At least one of white and black may be used for the identification unit 12. In addition, the identification unit 12 may indicate the identification information of the pig 70 by arranging a plurality of fluorescent colors. As a result, the visibility of the identification unit 12 can be improved.

Further, in the identification unit 12, a plurality of colors are arranged in a C shape (in other words, a Randold ring), but the plurality of colors may be arranged in a straight line or in a matrix. Good.

The connecting member 13 is a columnar (in other words, rod-shaped) member that stands on the first main surface 11a of the base material 11 and connects the base material 11 and the stopper 14. The connecting member 13 is mainly made of polyurethane resin. The connecting member 13 is formed integrally with the base material 11, for example, but may be a separate body from the base material 11.

A metal conical portion 13a is attached to the tip of the connecting member 13. When the animal identification member 10 is attached to the ear of the pig 70, the conical portion 13a penetrates the ear of the pig 70 and is pushed into the hole 14a of the stopper 14 by pressing with a special jig. Then, since the conical portion 13a is caught around the hole 14a, the stopper 14 functions as a retaining structure (in other words, a falling-out prevention structure) for the animal individual identification member 10.

The stopper 14 is a flat columnar member that functions as a retaining structure for the animal individual identification member 10. The stopper 14 is made of, for example, the same material as the base material 11. That is, the stopper 14 is mainly formed of polyurethane resin.

[Color of the second main surface]
In the animal individual identification member 10, the color of the second main surface 11b, which is the background color of the identification unit 12, is a color corresponding to the color of the body surface of the pig 70. For example, as shown in FIG. 1, when the pig 70 is a so-called white pig, the color of the second main surface 11b is white. Further, as shown in FIG. 4, when the pig 70 is a so-called black pig, the color of the second main surface 11b is black. As shown in FIG. 5, when the color of the body surface of the pig 70 is brown, the color of the second main surface 11b is brown. 4 and 5 are diagrams showing an example of the color of the second main surface 11b.

The color corresponding to the color of the body surface of the pig 70 means a color of the same system as the color of the body surface of the pig 70, and does not mean the color exactly the same as the color of the body surface of the pig 70. For example, when the color of the body surface of the pig 70 is pink and the color of the second main surface 11b of the individual identification member 10 for animals attached to the pig 70 is white, the second main surface 11b It can be said that the color of the pig 70 corresponds to the color of the body surface of the pig 70.

As described above, if the color of the second main surface 11b, which is the background color of the identification unit 12, is a color corresponding to the color of the body surface of the pig 70, the probability that the identification unit 12 is detected can be increased. FIG. 6 is a diagram showing experimental results regarding the number of detections of the individual identification member 10 for animals. The number of detections here is from the animal individual identification member 10 reflected in the moving image obtained by photographing the inside of the pig cell with a camera fixed in the pig cell by a system such as the animal information management system described later. It is a figure which shows the number of times (specifically, the number of times per day) that the identification information could be read.

FIG. 6 (1) shows the number of times this was detected when the animal identification member 10 having a black second main surface 11b was attached to the white pig. Each of (2) and (3) of FIG. 6 shows the number of times this was detected when the animal identification member 10 having a white second main surface 11b was attached to the white pig. As shown in FIG. 6, it can be said that (2) and (3) have a larger number of detections than (1) and are more likely to be detected. That is, if the color of the second main surface 11b, which is the background color of the identification unit 12, is a color corresponding to the color of the body surface of the pig 70, the probability that the identification unit 12 is detected can be increased.

The method of changing the color of the second main surface 11b to match the color of the body surface of the pig 70 is not particularly limited. For example, by mixing the dye into the raw material of the base material 11, the entire base material 11 may be colored according to the color of the body surface of the pig 70, or only the second main surface 11b of the base material 11 may be used. May be colored according to the color of the body surface of the pig 70 by applying a paint or attaching a seal.

[Modification 1: Color scheme of identification part]
There is room for consideration as to how to select a plurality of different colors (hereinafter, referred to as a first color, a second color, and a third color) included in the identification unit 12. .. For example, when the second main surface 11b is achromatic, three colors having different hue angles in the hue circle by 120 ° are adopted as the first color, the second color, and the third color. To. This makes it easier for the camera to distinguish the first color, the second color, and the third color. That is, the animal identification member 10 that is easily detected is realized. The achromatic color means a color having a saturation of 0, and the achromatic color includes white, black, and gray of various densities.

On the other hand, when the second main surface 11b is a chromatic color, if this chromatic color is defined as the fourth color, the hue is defined as the first color, the second color, the third color, and the fourth color. If colors having different hue angles in the ring by 90 ° are adopted, the first color, the second color, the third color, and the fourth color can be easily distinguished by the camera. That is, the animal identification member 10 that is easily detected is realized. FIG. 7 is a diagram (a diagram showing a hue circle) showing an example of a first color, a second color, a third color, and a fourth color.

As shown in FIG. 7, for the pig 70 having a brown body surface color, a reddish orange color may be adopted as the color of the second main surface 11b. In this case, the first color is yellowish green, which is 90 ° different in hue angle from the fourth color, and the second color is greenish blue, which is 90 ° different in hue angle from the first color. The color 3 is purple whose hue angle is 90 ° different from that of the second color. It should be noted that the difference in hue angle by 90 ° is not a strict meaning but a broad meaning. The hue angles may differ substantially by 90 ° (that is, about 90 °).

[Modification 2: Configuration in which identification units are provided on both sides]
As shown in FIG. 4, the identification unit 12 may be hidden in a pig with ears (specifically, the Large White pig, etc.). Therefore, the animal individual identification member 10 may further include an identification unit 12 on the stopper 14 side. FIG. 8A is a plan view of the surface side of the animal individual identification member according to such a modification, and FIG. 8B is a cross-sectional view of the animal individual identification member according to the modification. FIG. 8C is a plan view of the back surface side of the animal identification member according to the modified example.

Specifically, the animal individual identification member 10a according to the modified example includes a base material 11, an identification unit 12, a connecting member 13, a base material 15, and an identification unit 16. The base material 11 may be paraphrased as the first base material, the identification unit 12 as the first identification unit, the base material 15 as the second base material, and the identification unit 16 as the second identification unit.

The base material 15 is a disk-shaped member. The base material 15 is mainly formed of a polyurethane resin (polyurethane elastomer). The base material 15 is flexible and can be bent to some extent with bare hands. The base material 15 has a first main surface 15a in contact with the body surface of the pig 70 and a second main surface 15b opposite to the first main surface 15a (that is, facing back to the first main surface 15a). .. The color of the second main surface 15b is a color corresponding to the color of the body surface of the pig 70.

The base material 15 also functions as a stopper. Since the conical portion 13a of the connecting member 13 is inserted into the hole (not shown) of the base material 15 and the conical portion 13a is caught around the hole, the base material 15 has a retaining structure for the animal individual identification member 10a (not shown). In other words, it functions as a dropout prevention structure). In a state where the conical portion 13a is inserted into the hole of the base material 15, the connecting member 13 connects two base materials (base material 11 and base material 15) to each other (first main surface 11a and first main surface). The surfaces 15a) are connected (in other words, held) so as to face each other at intervals.

An identification unit 16 is provided on the second main surface 15b of the base material 15. The identification unit 16 is a portion that constitutes a so-called color code. That is, the identification unit 16 indicates the identification information of the pig 70 by arranging a plurality of colors. The configuration of the identification unit 16 is the same as that of the identification unit 12, and the identification unit 16 shows the same identification information as the identification unit 12.

Since the individual identification member 10a for animals is provided with identification portions on both the front surface and the back surface, even if one identification portion is hidden, the other identification portion may be detected. That is, it can be said that the animal individual identification member 10a is an animal individual identification member that is easily detected by the camera.

[Effects, etc.]
As described above, the animal identification member 10 includes a base material 11 having a first main surface 11a in contact with the body surface of the pig 70 and a second main surface 11b opposite to the first main surface 11a. The second main surface 11b is provided with an identification unit 12 that indicates identification information of the pig 70 by arranging a plurality of colors different from each other. The pig 70 is an example of an animal. The color of the second main surface 11b is a color corresponding to the color of the body surface of the pig 70.

Such an animal individual identification member 10 is more likely to be detected by a camera than an animal individual identification member whose second main surface 11b is not colored according to the color of the body surface of the animal.

Further, for example, the color of the second main surface 11b is an achromatic color corresponding to the color of the body surface of the pig 70.

In such an individual identification member 10 for animals, the first color, the second color, and the third color contained in the identification unit 12 are three colors having different hue angles in the hue circle by 120 °. Can be adopted, which makes it easier for the camera to distinguish the first color, the second color, and the third color. That is, such an individual identification member 10 for animals is easily detected by a camera.

Further, for example, the color of the second main surface 11b is a chromatic color corresponding to the color of the body surface of the pig 70.

Such an individual identification member 10 for animals is easily detected by a camera even when the color of the body surface of the pig 70 is chromatic.

Also, for example, the plurality of colors include a first color, a second color, and a third color that are different from each other, and the first color, the second color, the third color, and the like. The chromatic colors differ in hue angle in the hue circle by 90 °.

Such an individual identification member 10 for animals adopts a chromatic color as the color of the second main surface 11b, but the first color, the second color, and the third color can be easily distinguished by the camera. .. Such an individual identification member 10 for animals is easily detected by a camera.

Further, the animal individual identification member 10a includes two base materials provided with identification portions on the second main surface, and further connects the two base materials so that the first main surfaces face each other with a gap. A rod-shaped connecting member 13 is provided.

Since the individual identification member 10a for animals is provided with identification portions on both the front surface and the back surface, even if one identification portion is hidden, the other identification portion may be detected. That is, the animal individual identification member 10a is easily detected by the camera.

(Embodiment 2)
[Constitution]
In the second embodiment, an animal information management system using the animal individual identification member 10 will be described. FIG. 9 is a block diagram showing a functional configuration of the animal information management system according to the second embodiment. In the following description of the second embodiment, information processing for managing information about one pig 70 will be described, but in reality, in order to manage information for each of the plurality of pigs 70 in the pig cell. Similar information processing is performed on.

The animal information management system 100 is a system used by a pig 70 breeder to grasp the breeding status of the pig 70. As shown in FIG. 9, the animal information management system 100 includes an imaging unit 20 and a control unit 30. The imaging unit 20 and the control unit 30 may be realized as a single device.

The imaging unit 20 is installed on the ceiling or the like of the pig bunches, and acquires the image data of the images by capturing the images in the pig bunches. The image pickup unit 20 is a camera realized by, for example, a CMOS image sensor.

However, the image data storage unit 31 may automatically delete the stored image data at each stage when the stored image data is no longer needed. As a result, the memory capacity of the image data storage unit 31 can be reduced.

The identification information acquisition unit 32 acquires the identification information of the pig 70 based on the image data. The identification information acquisition unit 32 reads the identification information from the portion of the image data corresponding to the identification unit 12 of the animal individual identification member 10 by the image recognition process.

The position information acquisition unit 33 acquires the position information of the pig 70 based on the image data. Specifically, the position information acquisition unit 33 determines the position of the pig 70 based on the position of the pig 70 specified by the read identification information on the image data of the pig bunch.

The individual image data acquisition unit 34 acquires the individual image data of the pig 70 based on the image data. That is, the individual image data acquisition unit 34 cuts out the individual image data of the pig 70 from the image data of the entire pig bunch. In addition, the individual image data acquisition unit 34 creates image data of the projected shape of the pig 70 from the individual image data.

The projected shape image data is image data capable of identifying the contour of the pig 70. The information storage unit 35 stores the identification information, the position information, and the individual image data (specifically, the image data of the projected shape) of the pig 70 in association with each other.

The information storage unit 35 stores the identification information and the position information of the pig 70 as time series data. Time series data is a series of values having time information (time stamp). That is, the information storage unit 35 stores the identification information and the position information of the pig 70 in association with the information of the date and time when the identification information and the position information are acquired.

The movement amount estimation unit 36 estimates the movement amount of the pig 70 in a predetermined period, for example, one day, based on the time series data of the position information stored in the information storage unit 35. The amount of movement is, for example, the total length of the straight lines when the positions of the pigs 70 are connected by straight lines in chronological order. The estimated movement amount is stored in the information storage unit 35.

The body weight estimation unit 37 estimates the body weight of the pig 70 based on the individual image data (for example, projected shape data) of the pig 70 stored in the information storage unit 35. The estimated body weight is stored in the information storage unit 35.

The information output unit 38 is a communication circuit (communication module) for transmitting the information stored in the information storage unit 35 to the server 40 or the breeder's information terminal 60 via a wide area communication network such as the Internet. The communication performed by the information output unit 38 may be wired communication or wireless communication. The communication standard of the communication performed by the information output unit 38 is also not particularly limited. Specifically, the information terminal 60 is a portable information terminal such as a smartphone or tablet terminal, or a stationary information terminal such as a personal computer. If the various information described above is transmitted to the information terminal 60, the breeder can grasp the breeding status of the pig 70. The various types of information described above may be distributed to the information terminal 60 by the server 40.

[Effects, etc.]
