Abstract
Description
Technical Field
[0001] The utility model relates to an information acquisition device, in particular to an iris information acquisition device capable of identifying the identity of birds. Background Art
[0002] The technology of identity recognition keeps pace with the times. For example, identification through different features such as pupils and fingerprints can be used to identify birds in competitions or other occasions in addition to identifying humans. One existing way to identify birds is to identify them through iris features. Since the iris features of each bird are different, the iris information of the bird is captured and stored by the initial photography. It can be compared each time the iris information is captured to confirm the identity of the bird.
[0003] The conventional method of capturing the iris information of birds through photography is usually to insert the bird's head through a hole into a shell to limit the bird's activity space, and then set a camera at a fixed position in the shell to take photos, and then compare the iris information obtained through the photography through software or other methods. However, in the above method, the bird's head may still swing in the shell, and the size of each bird's head is different, resulting in that the camera set at a fixed position may not be able to accurately capture the bird's iris information. Utility Model Content
[0004] In order to solve the problem that the existing methods cannot accurately capture the iris information of birds, the purpose of the utility model is to propose an iris information capture device for bird identification that can adjust the angle and position of the camera according to the size and state of the bird, so as to accurately and clearly capture the iris information of the bird.
[0005] The utility model solves the technical problem of providing an iris information acquisition device for bird identification, which comprises:
[0006] A base;
[0007] a bracket, the bracket being arranged on the base;
[0008] Two cameras, the two cameras are arranged on the bracket at a distance and facing each other, and the two cameras can move linearly relative to the bracket in an adjustment direction; and
[0009] A receiving space, which is formed by half surrounding the bracket and the two cameras;
[0010] The bracket can be driven to swing around the accommodating space relative to the base.
[0011] The technical means of the present invention can achieve improved effects in that: the iris information capture device for bird identity recognition provided by the present invention, through the swinging of the bracket relative to the base around the accommodating space, and the linear movement of the two cameras relative to the bracket, can adjust the angles and positions of the two cameras according to the swinging and movement of the bird's head, and even according to the size and type of the bird when capturing the bird's iris information, so that the two cameras can be more accurately aimed at the bird's eyes and focus, thereby accurately and clearly capturing the bird's iris information and improving the accuracy of subsequent identity recognition.

[0019] In order to understand the technical features and practical effects of the utility model in detail and to realize the utility model according to the content of the new model, the preferred embodiment shown in the figure is further described in detail as follows:
[0020] like Figure 1 As shown, a preferred embodiment of the iris information capture device for bird identification of the utility model comprises a base 10, a bracket 20, two cameras 30 and a accommodating space 40, the bracket 20 is arranged on the base 10, the two cameras 30 are arranged on the bracket 20, and the accommodating space 40 is located between the two cameras 30.
[0021] The base 10 may adopt different structures, for example Figure 1 and Figure 2As shown, in a preferred embodiment of the present invention, the base 10 includes a bottom plate 11 and two upright plates 12. The bottom plate 11 includes upper and lower surfaces facing opposite directions. The two upright plates 12 are arranged on the bottom plate 11 at intervals and extend upright from the upper surface of the bottom plate 11 to provide the bracket 20. The bottom plate 11 can improve the stability of the iris information capture device. In other embodiments, multiple supporting legs can also be arranged on a plane, which is not limited to the preferred embodiment of the present invention.
[0022] like Figures 2 to 4 As shown, the bracket 20 is swingably disposed on the base 10. In a preferred embodiment of the utility model, the bracket 20 is provided with a guide hole 21, and the base 10 is provided with a coupling pin 13. The coupling pin 13 penetrates the guide hole 21, so that the bracket 20 is coupled to the base 10, and the coupling pin 13 can move along the guide hole 21, so that the bracket 20 can swing relative to the base 10. More specifically, the coupling pin 13 is disposed between the two upright plates 12, and the bracket 20 is disposed between the two upright plates 12, so that the coupling pin 13 can penetrate the guide hole 21.
[0023] like Figure 2 and Figure 3 As shown, the two cameras 30 are spaced apart and disposed on the bracket 20 facing each other. The term “disposed facing each other” means that the lens of the camera 30 faces the lens of the other camera 30. Figure 5 As shown, each camera 30 can move linearly in an adjustment direction relative to the bracket 20, so as to adjust the position of the camera 30.
[0024] like Figure 3 As shown above, the accommodating space 40 is located between the two cameras 30, so that the bird can put its head between the two cameras 30. Specifically, the accommodating space 40 is formed by semi-surrounding the two cameras 30 and the bracket 20. The semi-surrounding means that the accommodating space 40 is not completely surrounded and closed by the two cameras 30 and the bracket 20. Figure 3 In general, the accommodating space 40 covers a range between the two cameras 30 , extending from the top of the bracket 20 to the space between the tops of the two cameras 30 .
[0025] Specifically, the aforementioned bracket 20 can swing relative to the base 10, which means that the bracket 20 swings around the accommodating space 40, and the adjustment direction along which each camera 30 moves linearly relative to the bracket 20 can change with the swinging of the bracket 20 and is not limited to a specific direction.
[0026] The iris information acquisition device of the utility model acquires the iris information of birds by video recording. First, Figure 6As shown, the operator brings a bird 90 whose iris information is to be captured to the iris information capturing device, and inserts the head of the bird 90 into the accommodating space 40, that is, between the two cameras 30, and aligns the two cameras 30 with the eyes on both sides of the head of the bird 90. Since the head of the bird 90 may move in the accommodating space 40, at this time, the bracket 20 can be swung and the two cameras 30 can be adjusted by the mechanism of moving.
[0027] For example, when the head of the bird 90 swings or moves left and right in the accommodation space 40, the two cameras 30 may not be able to accurately face the eyes of the bird 90 and cannot focus. Figure 3 to Figure 4 As shown, an external force is used to drive the bracket 20 to swing relative to the base 10 around the accommodating space 40, so that the two cameras 30 are adjusted from the original nearly horizontal angle to an inclined angle to correspond to the angle of the head of the bird 90, so that the two cameras 30 can be aimed at the eyes of the bird 90, and Figure 5 As shown, each of the cameras 30 is linearly moved relative to the bracket 20 to adjust the distance between the camera 30 and the eye of the bird 90 to achieve a focusing effect. In this way, the two cameras 30 can accurately capture iris information.
[0028] In addition to the above-mentioned angle adjustment corresponding to the swing of the head of the bird 90, the swing mechanism of the bracket 20 relative to the base 10 can also allow the operator to insert the head of the bird 90 into the accommodating space 40 at different angles. Figure 6 As shown, the support 20 can be maintained in a balanced position so that the two cameras 30 are arranged horizontally, and the operator can insert the head of the bird 90 into the accommodating space 40 at a correct angle. Figure 7 As shown, the support 20 can also be swung relative to the base 10 so that the two cameras 30 are vertically arranged, and the operator can insert the head of the bird 90 into the accommodating space 40 at an angle where the bird 90 lies on its side. In this way, the iris information capture device can adjust the angles of the two cameras 30 according to the operator's habits or the structure of other iris capture related equipment, so that the two cameras 30 can be respectively directed toward the eyes of the bird 90 to accurately capture iris information.
[0029] In addition, when it is desired to capture iris information of birds of different species and sizes, the head size, eye position and other body features of different birds are not the same. At this time, the iris information capture device can also ensure that the two cameras 30 are respectively aimed at the eyes of the bird and can focus by swinging the bracket 20 relative to the base 10 and linearly moving the camera 30 relative to the bracket 20, thereby improving the accuracy and clarity of the captured iris information. Based on the above, the utility model can provide an iris information capture device that can accurately and clearly capture the iris information of birds.
[0030] By storing the iris information captured by the iris information capture device, the iris information of the bird can be captured by the iris information capture device in subsequent competitions or other occasions, and the iris information captured this time can be compared with the previously stored iris information. Clear and accurate iris information can improve the accuracy of bird identification. For example, in bird competitions, the above-mentioned identification method can be used to prevent contestants from cheating by changing birds, thereby improving the anti-cheating effect of the competition.
[0031] In a preferred embodiment of the present invention, the guide hole 21 is provided on the bracket 20, and the combining pin 13 is provided on the base 10. In another embodiment, the guide hole 21 can also be provided on the base 10. Specifically, the size of the two upright plates 12 of the base 10 can be designed to be larger so that the longer guide hole 21 can be provided thereon, and the combining pin 13 can be provided on the bracket 20. At the same time, the bracket 20 maintains the original size design to retain the mechanism of linear movement of the two cameras 30. In this way, the combining pin 13 can also be inserted into the guide hole 21, so that the bracket 20 can be swingably combined with the base 10. The arrangement of the guide hole 21 and the combining pin 13 is not limited to the preferred embodiment of the present invention.
[0032] In addition, in other embodiments, the base 10 can also be connected to the bracket 20 by setting a swing arm, so that the bracket 20 can be swingably combined with the base 10. As long as the bracket 20 can swing around the accommodating space 40 relative to the base 10 when driven by an external force, the form in which the bracket 20 is set on the base 10 is not limited to the above.
[0033] Further, if Figure 3 and Figure 4As shown, in a preferred embodiment of the utility model, the guide hole 21 extends along the edge of the accommodating space 40 and is in an arc shape, and the arc shape is specifically an elliptical arc shape. The coupling pin 13 is confined in the arc-shaped guide hole 21 and moves along the guide hole 21, so that the trajectory of the swing of the bracket 20 relative to the base 10 is an arc around the accommodating space 40. Thereby, when the bracket 20 swings, the bracket 20 is less likely to produce a strong collision with the head of the bird 90 extending into the accommodating space 40.
[0034] Going further, Figure 3 As shown, in a preferred embodiment of the utility model, the accommodating space 40 extends toward the bracket 20, so that the bracket 20 is recessed to form a recess 23. The recess 23 formed by the recess of the bracket 20 increases the size of the accommodating space 40. When the iris information of a bird with a larger head is to be captured, sufficient space can be provided for the bird's head and neck to extend into. Thereby, the application scope of the iris information capture device can be increased, and it can be applicable to more different birds and avoid making the birds feel uncomfortable.
[0035] Preferably, in a preferred embodiment of the present invention, the bracket 20 disposed between the two upright plates 12 has a plate-like structure, and the two sides of the bracket 20 are respectively abutted against the two upright plates 12. When the bracket 20 is to be swung relative to the base 10, a certain external force is required to overcome the friction between the bracket 20 and the two bases 10; and when the bracket 20 is swung relative to the base 10 and the angles of the two cameras 30 are adjusted, the friction between the bracket 20 and the two bases 10 can temporarily maintain the positions of the bracket 20 and the two cameras 30 fixed.
[0036] In addition, if Figure 2 As shown, in a preferred embodiment of the utility model, the bracket 20 includes two adjustment long holes 22, the two adjustment long holes 22 are spaced apart and arranged in a straight line, and each of the cameras 30 is provided with a through hole 32, which can be penetrated by a bolt 51 and a corresponding one of the adjustment long holes 22, and screwed with a nut 52, so that the camera 30 is set on the bracket 20. Specifically, the bracket 20 is an arc-shaped plate body, the two adjustment long holes 22 are respectively located at the two ends of the bracket 20, and each of the cameras 30 includes a body 31 and an extension plate 33, the extension plate 33 is extended from the bottom of the body 31, and the through hole 32 is formed on the extension plate 33.
[0037] When the two cameras 30 need to be adjusted, the bolt 51 and the nut 52 are loosened, thereby the extension plate 33 and the bracket 20 can be slightly loosened. Since the bolt 51 is still inserted into the adjustment long hole 22 and the through hole 32 at this time, the bolt 51 can be moved along the adjustment long hole 22, so that the camera 30 moves linearly relative to the bracket 20 along the direction of the adjustment long hole 22, that is, the aforementioned adjustment direction; and when the adjustment is completed, the bolt 51 and the nut 52 are tightened again, so that the extension plate 33 of the camera 30 and the bracket 20 are clamped and fixed, so that the camera 30 and the bracket 20 are relatively fixed.
[0038] In other embodiments, the two cameras 30 and the bracket 20 may also achieve a linear movement mechanism through other structural designs (e.g., slide rails), and after adjustment, the cameras 30 and the bracket 20 may be relatively fixed by a clamp. The form in which the two cameras 30 are arranged on the bracket 20 is not limited to the preferred embodiments of the present invention.
[0039] More preferably, if Figure 2 , Figure 6 and Figure 7 As shown, in a preferred embodiment of the present invention, the camera 30 is an infrared camera, which is provided with a plurality of infrared emitters 34, which are arranged around a lens of the camera 30 and can emit infrared light toward the accommodation space 40. By increasing the infrared light and the characteristic that the camera 30 adopts an infrared camera and only senses infrared light, other light sources in the environment can be filtered out, thereby improving the clarity of the captured iris information.
[0040] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any person with ordinary knowledge in the technical field can make equivalent embodiments by partial changes or modifications to the technical content disclosed in the utility model without departing from the scope of the technical solution of the utility model, and they still fall within the scope of the technical solution of the utility model without departing from the technical solution of the utility model.
