Referring to the ninth to sixteenth figures, the features of the eye portion 41 of the identifiable racing pigeon 40 include: the shape of the eyelid 42, the shape and angle of the pupil 43 , the particle distribution of the iris 44 of the eyeball, and the chromatic aberration, the pupil outer ring. The shadow portion 45, the eye 41 of the racing pigeon 40, the line 46 of the head 46 and the bird's beak 47, 471, 472, or the line shape 48 of at least three feature points of the eye of the pigeon eye are for identification. The annex is a color drawing of the ninth to sixteenth paragraphs of the case. I would like to provide it to the Administration for reference.

This embodiment is illustrated by four racing pigeons 40a, 40b, 40c, 40d, as shown in the ninth figure, showing the close-ups of the heads of each racing pigeon and its eye parts 41a, 41b, 41c, 41d; The shape of the eyelid 42 of the eye portion 41 of the racing pigeon 40 refers to the shape of the skin surrounding the skin around the eyeball, and the tenth figure depicts the eyelids 42a, 42b of the four racing pigeons 40a, 40b, 40c, 40d in bold lines. The contour lines of 42c and 42d, the eyelids 42a, 42b, 42c, 42d of the four racing pigeons have different wrinkle growth positions and shapes, so the shape of the eyelids 42 of different racing pigeons must be different, which can be used to identify each pigeon. The biometrics of the identity of 40.

Referring to Figure 11, the shape of the pupil 43 of the eye portion 41 of the racing pigeon 40 refers to the shape of the black circular area in the center of the eyeball, and the pupils 43a, 43b, 43c, 43d of the four racing pigeons 40a, 40b, 40c, 40d. The size, shape and contour are different; since the shape of the pupil 43 of each pigeon is different, for example, it is elliptical, and the orientation and angle of the ellipse of the pupil are different. The staff can select three tangent lines 431, 432, and 433 according to the shape feature of each pupil. The three tangent lines 431, 432, and 433 can form a triangular shape, and the triangular shapes formed by the tangent lines of different pupils are also different, so the pupil 43 is different. The shape can also be used as a biometric to identify the identity of the racing pigeon 40.

Referring to Figure 12, the iris 44 of the pigeon eye has different rainbow pigments that form a granular shape. The particle shape, particle distribution, and color and chromatic aberration of the iris in the different pigeons 44 are also different. The staff can select the appropriate range on the irises 44a, 44b, 44c, 44d of the four racing pigeons 40a, 40b, 40c, 40d as the matching regions (441a, 442a), (441b, 442b), 441c, 442c), (441d, 442d) are identified by the shape and distribution of the particles in the alignment region. The color difference of the whole iris 44 can also be recognized as an identity, as shown in the thirteenth figure. Therefore, the characteristics of the iris 44 of the pigeon eye can be used to identify different racing pigeons 40.

Referring to Figure 14, the outer ring of the dove 43 of the dove has a shaded portion 45 which is lighter in color than the pupil 43. Different pigeons 40a, The shape, size, position and color depth of the shaded portions 45a, 45b, 45c, 45d of the outer ring of the 40b, 40c, 40d pupils 43a, 43b, 43c, 43d are different, for example, the shadow portion 45a of the pigeon 40a is semicircular The shadow portion 45c of the pigeon 40c is completely round. The positions of the shadow portions 45a, 45b, 45c, 45d of the different pigeons at the pupils 43 are also different. The pupils 43a, 43b can be represented by three area lines (451a, 452a, 453a), (451b, 452b, 453b), (451c, 452c, 453c), (451d, 452d, 453d), by using different characteristics of the shadow portion 45. The range of the shaded portions 45a, 45b, 45c, 45d of the outer ring of 43c, 43d, for example, the shaded portion 45a of the bore 43a of the racing pigeon 40a is only half a turn, and is located at the lower right of the bore 43a, and uses three regional lines (451a, 452a, 453a) indicates the range of the shaded portion 45a, and the shaded portion 45c of the pupil 43c of the racing pigeon 40c completely surrounds the outer circumference of the pupil 43c, and the range of the shaded portion 45c is represented by three area lines (451c, 452c, 453c), thus, utilizing The range and position of the shaded portion 45 of the pupil 43 of each racing pigeon 40 can identify different racing pigeons and verify the identity of each of the racing pigeons 40.

In addition to the various identification features presented by the eye part 41 of the racing pigeon 40, the outline of the head organ of the racing pigeon 40 can also be used as an identification feature, see Figure 15, due to the appearance of the head organ of the pigeon. They are all different. The eye part 41 of the pigeon 40 has a different distance from the head 46. Therefore, the length of the line 461 between the specific point of the eye part 41 of different pigeons and the specific point of the head is different, and the specific point of the eye is different. The line 471 between the specific points of the pigeon's nose, and the line 472 between the specific point of the eye and the specific point of the bird's beak 47, the length of the lines 461, 471, 472 and the angle of inclination between them, in different pigeons It will also be different. Therefore, the use of the eyes, the head and the guanine connection, can form the characteristics of each pigeon for identification.

Furthermore, please refer to the sixteenth figure, select at least three different feature points from the eyelids of different pigeons, and connect the three feature points to the lines 481, 482, 483 to form a triangle 48, and then take it in the future verification. Verify the same three points, Whether the comparison matches. In practice, more than three feature points can be selected from the pigeon eye and connected into a polygon for identification.

In addition, the eye features or feature points of the racing pigeon 40 can be photographed or made into a three-dimensional map, so that the characteristics of each racing pigeon 40 can be more clearly distinguished, and the difference in the feature points of the different racing pigeons 40 can be more conveniently compared.

Please refer to the third and seventh figures. The seventeenth figure shows the verification method of the present invention, and the flow chart of the game ranking from the step (D) to the step (H). As described above, the verification report procedure of step (D) is performed by first identifying the identification component 10 to confirm whether the identity of the pigeon is consistent with the pigeon information. When the eye feature points of the pigeons are compared, the previously stored digital data is obtained by the storage medium 56, and at least one feature point of each pigeon is matched to the digital data, for example, One or more of the shadows of the eyelids, pupils, irises, and pupils. The identified pigeons will be entered and the steps (E) through (H) will be carried out in sequence. Before the competition, the verification of the identity of the pigeons can also identify the characteristics of the head of the eye and then verify the information on the pigeons.

Step (E) is carried out after collecting the pigeons, and the verified pigeons are carried to the competition place and released. Each of the owners carries their own reading device 20 back to the loft to wait for the pigeons to return to the nest.

Regarding the step (F), when the racing pigeon returns to the nest, the reading device 25 first reads the electronic serial number of the wafer 12 of the identification component 10 of the returning pigeon and the random code of the entry, and if the verification is correct, the return record is established. The electronic serial number, the entry code and a return time of the wafer 12 containing the identification component 10 of the racing pigeon are recorded to facilitate the organizer to discharge the pigeon ranking. If the verification is not true, no return record will be established.

In step (G), after the game is closed, the verification device 25 obtains a record of the return time of each pigeon and identifies the characteristics of the eye of the pigeon.

Finally, in step (H), the return time of the pigeons passed will be verified. The calculated speed is discharged. Preferably, for the pigeons that complete step (G) and have the opportunity to win the competition, the pigeon eye features are again compared to confirm whether the pigeons returning to the nest are indeed the pigeons of the competition. After the characteristics of the department are confirmed to be met, the ranking of the game begins.

It should be noted that in step (G), for the returning pigeons who are qualified to participate in the competition, the eye features of the pigeons can be photographed at the owner of the pigeons, and the digital data of the close-up photographs taken can be transmitted by network. To the recipient designated by the organizer (the recipient includes the organizer itself), and compare with the characteristic data stored in the storage medium to verify the authenticity of the pigeon. In addition, in the step (G), after the game deadline, the data in each of the interpretation devices can be verified again, and the data in the interpretation device is verified to be valid at the beginning to rank the pigeons.

The invention verifies the identity of the participating pigeons by photographing at least one characteristic of the head and the eye parts of the racing pigeon to confirm whether the racing pigeons have been adjusted, due to the shape of the eyelid of each racing pigeon, the shape and angle of the pupil The distribution and chromatic aberration of the iris of the eyeball, the shape, size and color of the shaded part of the pupil of the pupil, and the length and angle of the line of the pigeon's eye with the top of the pigeon and the guanine are not the same. It is possible to prevent fraudsters from changing the identification elements worn on the racing pigeons or replacing and modifying the pigeon information in the wafers of the identification components. The young pigeons who have been trained and competed for many years of experience can pretend to participate in the young birds competition. The fraud happens and the initiative to improve the fairness of the game is achieved.

The above description is intended to be illustrative of the possible embodiments of the present invention, and is not intended to limit the scope of the present invention. In the scope of patents.
