Description

Technical Field

[0001] The present invention relates to the technical field of animal image acquisition, and in particular to an animal facial image acquisition device. Background Art

[0002] Traditional animal identity authentication generally uses ear tags or electronic tags, but ear tags and electronic tags are usually easy to fall off or lose, which brings many inconveniences to animal management. In addition, the existing animal management field also uses an injectable electronic tag, which is an electronic tag encapsulated with biologically compatible materials planted in the animal's body. The basic information of the animal, vaccination status, etc. can be obtained by scanning the electronic tag implanted in the animal's body with a scanning instrument. However, this subcutaneous injection method is prone to cause the electronic tag to become free or the animal to be allergic, and even worse, it can cause the animal to die. Therefore, in the field of animal management, non-invasive methods of identity authentication through facial recognition or iris recognition are gaining more and more attention.

[0003] However, in the process of collecting animal head images, unlike the stability of humans when taking images, animals often dodge, run around and move around when taking head images, resulting in problems such as low resolution of the collected images or failure to capture the target, which causes great trouble to the work of collecting animal head images.

[0079] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings.

[0080] Example

[0081] Figure 1 The first animal facial image acquisition device provided by the embodiment of the present invention is shown, and the animal facial image acquisition device is used to be mounted on the neck of an animal and acquire the animal facial image. The animal facial image acquisition device includes: a fixing member 10, a supporting component 20, an orientation adjustment component 30 and a camera 40.

[0082] The fixing member 10 is used to be mounted on the neck or back of an animal, the supporting component 20 is slidably disposed on the fixing member 10 along a first direction, the orientation adjustment component 30 is slidably disposed on the supporting component 20 along a second direction, and the camera 40 is disposed on the orientation adjustment component 30 for capturing images of the animal's face.

[0083] The first direction and the second direction are different.

[0084] When the fixing member 10 is sleeved on the neck of an animal, the fixing member 10 is an annular fixing member, and the first direction is an annular direction along the annular fixing member.

[0085] In this embodiment, the annular fixing member is a circular annular fixing member 11, and the first direction is a circumferential direction along the surface of the circular annular fixing member 11. In some other embodiments, the annular fixing member may also be a polygonal annular fixing member, such as a triangular annular fixing member, a quadrilateral annular fixing member, a trapezoidal annular fixing member or a hexagonal annular fixing member, etc., which are not limited here, and the first direction is a polygonal direction of the surface of the polygonal annular fixing member.

[0086] It is worth noting that the annular fixing member 11 does not only refer to the strict annular shape in Euclidean geometry, and any deviation within a predetermined range (the predetermined range is based on the ability to be mounted on the neck of an animal) can be within the protection scope of the present invention.

[0087] When the fixing part 10 is sleeved on the back of the animal, the fixing part 10 can be similar to a pet chest harness or a pet leash, and of course can also be a more solid structure than a pet chest harness or a pet leash, and can be sleeved between the animal's forelimbs and neck, or between the animal's forelimbs and hind limbs, which is not limited here.

[0088] When the fixing member 10 is a structure similar to a pet chest harness or a pet traction rope, and the fixing member 10 is sleeved on the back of the animal, in this embodiment, the support assembly 20 can be arranged at the position of the fixing member 10 located on the back of the animal. Of course, in some other embodiments, the support assembly 20 can also be arranged at other positions of the fixing member 10, subject to the camera 40 being able to capture the animal's facial image, which is not limited here.

[0089] In the embodiments of the present invention, the example of the fixing member 10 being mounted on the neck of an animal is used for explanation. Those skilled in the art will understand that, except that the structure of the fixing member 10 when it is mounted on the neck of an animal is different from the structure of the fixing member 10 itself when it is mounted on the back of an animal, other structures of the animal facial image acquisition device (such as the support component 20, the orientation adjustment component 30 and the camera 40) are the same and will not be described one by one here.

[0090] The fixing member 10 is provided with a first slide rail 13 extending along the first direction. In this embodiment, in order to make the collection range of the animal facial image collection device larger, when the fixing member 10 is mounted on the neck of the animal, the first slide rail 13 is closer to the head of the animal. For example, when the fixing member 10 is a circular ring-shaped fixing member, and the circular ring-shaped fixing member is mounted on the neck of the animal, the section of the circular ring-shaped fixing member closest to the animal's head is the lower section, and the section away from the animal's head is the upper section. The first slide rail 13 is set at a preset distance from the lower section in the circumferential direction of the surface of the circular ring-shaped fixing member. The preset distance can be 10mm, 20mm, 30mm, 40mm, etc., which can be determined according to user needs and is not limited here. Of course, the first slide rail 13 can also be set at any position on the circumferential direction of the surface of the fixing member 10. For example, the first slide rail 13 can be set at a preset position on the circumferential direction of the surface of the fixing member 10 at a distance from the upper section, or the first slide rail 13 can be set at a position between the upper section and the lower section. The range in which the camera 40 connected to the orientation adjustment component 30 can capture the animal's facial image is within the protection range.

[0091] In this embodiment, the animal face image acquisition device may further include a slide rail 111, on which a first slide rail 13 is provided, and the slide rail 111 covers the surface of the fixing member 10. In some other embodiments, the first slide rail 13 may be directly provided on the fixing member 10.

[0092] As a preferred solution, when the first slide rail 13 is arranged on the surface of the slide rail sheet 111, the degree of curvature of the first slide rail 13 can be consistent with the degree of curvature of the slide rail sheet 111; when the first slide rail 13 is arranged on the surface of the fixing member 10, the degree of curvature of the first slide rail 13 can be consistent with the degree of curvature of the fixing member 10.

[0093] Furthermore, the first slide rail includes at least two different movement directions.

[0094] In this embodiment, the first slide rail 13 can be a single linear rail, and the linear rail has two movement directions, namely, the head and the tail. In some other embodiments, the first slide rail 13 can also be a multi-directional rail formed by a combination of multiple linear rails. For example, the first slide rail 13 can be a "cross"-shaped rail formed by a combination of two linear rails. The "cross"-shaped rail has four different movement directions. In the "cross"-shaped rail, the support assembly can slide along the four movement directions of the "cross" in the "cross"-shaped rail. Of course, the multiple linear rails can also be combined to form other multi-directional rails, such as a "U" shape, etc., depending on the specific usage scenario.

[0095] Of course, in addition to the linear track, the first slide rail 13 can also be a curved track, or a track including at least two different movement directions formed by a combination of multiple curved tracks, which is not limited here.

[0096] When the first slide rail 13 is a single linear track or a curved track, in order to allow the support assembly 20 arranged on the first slide rail 13 to have a larger sliding range, the angle between the first straight line formed after the first slide rail 13 is unfolded and the lower cross-section of the annular fixing member satisfies the preset offset angle range, that is, the angle between the first straight line formed by unfolding the first slide rail 13 and the plane where the lower cross-section of the annular fixing member is located is within the preset offset angle range, for example, the preset offset angle range can be set to 0°~20°. When the preset offset angle is 0°, the first straight line formed by unfolding the first slide rail 13 is parallel to the lower cross-section of the annular fixing member. At this time, the support assembly 20 arranged on the first slide rail 13 has the largest sliding span along the first slide rail 13.

[0097] Furthermore, when the fixing member 10 is the annular fixing member, the first slide rail 13 can be an arc-shaped slide rail, and the central angle corresponding to the line between the two end points of the first slide rail 13 can range from 30° to 360°. Of course, in order to reduce the complexity and unnecessary sliding of the animal facial image acquisition device, the central angle corresponding to the first slide rail 13 preferably ranges from 60° to 180°, so that when the animal facial image acquisition device is mounted on the neck of the animal, the camera 40 can capture clear animal facial images.

[0098] The supporting assembly 20 includes a first sliding member 21 and a supporting plate 22 .

[0099] The first sliding member 21 is disposed on the first slide rail 13 and is used to slide in the first slide rail 13. The support plate 22 is connected to the first sliding member 21, and the first sliding member 21 drives the support plate 22 to slide in the first slide rail 13.

[0100] Specifically, the support plate 22 is provided with a second slide rail 23 along the second direction; and the orientation adjustment assembly 30 is provided on the second slide rail 23 .

[0101] In this embodiment, the support plate 22 may be in the shape of a fan ring. In some other embodiments, the support plate 22 may also be in the shape of an isosceles trapezoid, a rectangle, an ellipse, etc. Since the first sliding member 21 drives the support plate 22 to slide in the first slide rail 13, as a preferred solution, the curvature of the support plate 22 may be set to be consistent with the curvature of the first slide rail 13 to improve the smoothness of the support plate 22 when sliding on the first slide rail 13.

[0102] In this embodiment, the support plate 22 may be made of metal, plastic, synthetic rubber or other materials, which are not limited herein.

[0103] Furthermore, the second slide rail 23 includes at least two different movement directions.

[0104] In this embodiment, the second slide rail 23 can be a single linear rail, and the linear rail has two movement directions, namely, the head and the tail. In some other embodiments, the second slide rail 23 can also be a multi-directional rail formed by a combination of multiple linear rails. For example, the second slide rail 23 can be a "cross"-shaped rail formed by a combination of two linear rails. The "cross"-shaped rail has four different movement directions. In the "cross"-shaped rail, the orientation adjustment component 30 can slide along the four movement directions of the "cross" in the "cross"-shaped rail. Of course, the multiple linear rails can also be combined to form other multi-directional rails, such as a "U" shape, etc., depending on the specific usage scenario.

[0105] Of course, in addition to the linear track, the second slide rail 23 can also be a curved track, or a track including at least two different movement directions formed by a combination of multiple curved tracks, which is not limited here.

[0106] In this embodiment, the first slide rail 13 may be a linear hole provided on the fixing member 10 or the slide rail sheet 111, and the first sliding member 21 matches the first slide rail 13, so that the first sliding member 21 slides along the first slide rail 13. Of course, in some other embodiments, the first slide rail 13 may also be a groove-type slide rail provided on the fixing member 10, such as a curtain slide rail, etc., which is not limited here.

[0107] When adjusting the position of the camera 40 , the support plate 22 can be moved along the first slide rail 13 via the second sliding member 31 .

[0108] Furthermore, the first sliding member 21 may include at least one sliding block. For example, in order to improve the stability of the support assembly 20 when sliding in the first slide rail 13, the first sliding member 21 may be two sliding blocks, and the two sliding blocks are matched with the first slide rail 13, so that the two sliding blocks drive the support plate 22 to slide along the first slide rail 13.

[0109] Combination Figure 1 and Figure 2 The azimuth adjustment component 30 includes a second sliding member 31 and an azimuth adjustment member 32 , and the azimuth adjustment member 32 includes an extension member 321 and an angle adjustment member 322 .

[0110] The second sliding member 31 is arranged on the second sliding rail 23, the extending member 321 is arranged on the second sliding member 31, the angle adjusting member 322 is connected to the extending member 321, and the camera 40 is connected to the angle adjusting member 322. The angle adjusting member 322 can adjust the rotation angle of the camera 40 connected thereto, so that the camera 40 can rotate within a predetermined angle range, thereby enabling the camera 40 to capture images of the animal's face in multiple directions and multiple positions.

[0111] Further, the second slide rail 23 may be a linear hole arranged along the second direction on the support plate 22, and the second sliding member 31 may include at least one sliding block, the at least one sliding block matches the second slide rail 23, and the at least one sliding block passes through the second slide rail 23 and is connected to the extension member 321, that is, the support plate 22 is arranged between the second sliding member 31 and the extension member 321. Of course, in some other embodiments, the second slide rail 23 may also be a groove-type slide rail arranged on the support plate 22, such as a curtain slide rail, etc., which is not limited here.

[0112] When the first sliding member 21 slides along the first slide rail 13, the first sliding member 21 drives the support plate 22 connected thereto to slide along the first slide rail 13. When the second sliding member 31 slides along the second slide rail 23, the second sliding member 31 drives the azimuth adjustment member 32 connected thereto to slide along the second slide rail 23. The angle adjustment member 322 can adjust the rotation angle of the camera 40, further expanding the range of motion of the camera 40, thereby enabling the camera 40 to capture images of animal heads within a larger range.

[0113] In this embodiment, the angle adjustment member 322 may be a universal joint. The universal joint may use its location as the origin, and drive the camera 40 connected thereto to rotate 360° around the origin, so that the acquisition range of the camera 40 is larger and there is no acquisition blind spot. Of course, the angle adjustment member 322 may also be a universal joint chain formed by connecting multiple universal joints to further expand the angle adjustment range of the angle adjustment member 322. In some other embodiments, the angle adjustment member 322 may also be other types of angle adjustment mechanisms, such as a pan / tilt, an angle adjustment bracket, etc.

[0114] Furthermore, in order to ensure that the camera 40 has a larger sliding range, the extension member 321 may also be a telescopic structure.

[0115] When the extension member 321 is a telescopic structure, Figure 3 As shown, the extension member 321 includes a plurality of first rods 3211, and the plurality of first rods 3211 form a stepped socket. Each first rod 3211 may be provided with a locking portion, and the locking portion may realize telescopic locking between the plurality of first rods 3211, similar to the telescopic rod function of an ordinary umbrella.

[0116] like Figure 4 As shown, the extension member 321 also includes a plurality of second rod bodies 3212, and the plurality of second rod bodies 3212 can also be connected by snapping in sequence. One end of each second rod body 3212 is provided with an "L"-shaped slot, and the other end is provided with a snap. The radius of the rod body at the end of the second rod body 3212 provided with the snap is smaller than the radius of the rod body at the end provided with the slot. The plurality of second rod bodies 3212 are connected by snapping. The end of the second rod body 3212 provided with the snap is inserted into the end of the other second rod body 3212 provided with the "L"-shaped slot, and the second rod body 3212 where the snap is located is rotated to insert the snap into the bending portion (such as the bending portion) of the "L"-shaped slot. Figure 7 The tail of the “L”-shaped slot shown in FIG. 1 is provided to fully fix the two second rod bodies 3212 .

[0117] In some other embodiments, the extension member 321 may also be a bendable structure. For example, the extension member 321 includes a plurality of third rods, which are connected in a hinged manner and can be bent at the hinge interface to reduce the length of the extension member 321, increase the moving range of the camera 40, and facilitate the user to carry it.

[0118] It is worth noting that the camera 40 may include a lens group, a photosensitive unit and a processing unit, which are not limited here.

[0119] It is worth noting that the animal facial image acquisition device may also be provided with at least a wireless module and a power module, the power module is used to power the wireless module, and may be a dry cell, a dry cell battery pack, or a power socket (the power socket is used to power the animal facial image acquisition device through an external mains), etc. The wireless module is used to transmit the animal facial image captured by the camera 40 to an external terminal, so that the external terminal can further analyze the animal facial image.

[0120] In addition, the animal facial image acquisition device may also be provided with at least a storage module and a power module, wherein the power module is used to supply power to the storage module. The storage module is used to store the animal facial image captured by the camera 40. The animal facial image stored in the storage module may also be transmitted to an external terminal via an external data line, so that the external terminal further analyzes the animal facial image.

[0121] Further, when the fixing member 10 is a polygonal annular fixing member, the first direction may be the direction along the polygon on the surface of the polygonal annular fixing member, and the first slide rail may be arranged along the first direction at the preset position (for example, the position close to the lower cross section) on the surface where at least one side is located. For example, in a triangular annular fixing member, a first slide rail may be arranged at a preset position close to the animal's head direction on the annular surface where the first side of the triangle is located, and a first slide rail may be arranged at a preset position close to the animal's head direction on the annular surface where the second side is located, and a first group of support components, orientation adjustment components and cameras may be arranged on the first slide rail in the above manner, and a second group of support components, orientation adjustment components and cameras may be arranged on the first slide rail in the above manner. For example, when collecting facial images of animals, facial images of one side of the animal may be collected by the camera in the first group, and facial images of the other side of the animal may be collected by the camera in the second group. In addition, the cameras in the first group and the cameras in the second group may also collect facial images of the left and right sides of the animal at the same time. Of course, other polygonal annular fixing members such as quadrilateral annular fixing members and hexagonal annular fixing members can also set cameras in the same way as the triangular annular fixing member. The number of first slide rails can be determined according to actual user needs and will not be repeated here.

[0122] When the animal facial image acquisition device is mounted on the neck of the animal, the second direction is defined as a direction on the support plate 22 away from the fixing member 10 .

[0123] As a preferred solution, the second direction may be, for example, the direction from the position closest to the animal's neck to the position closest to the animal's head on the support plate 22 when the animal facial image acquisition device is mounted on the animal's neck.

[0124] As a most preferred solution, the first direction is perpendicular to the second direction.

[0125] Specifically, if the first slide rail 13 is straightened to obtain a first straight line, and the second slide rail 23 is straightened to obtain a second straight line, the first straight line can be perpendicular to the second straight line. This solution can enable the second sliding member 31 arranged on the second slide rail 23 to have a maximum movement range, and thus enable the camera 40 connected to the angle adjustment member 322 to have a maximum shooting range.

[0126] Of course, the angle between the first direction and the second direction can also be offset within a predetermined angle range based on 90°, which can be determined according to user needs and manufacturing process and is not limited here.

[0127] As a preferred solution, the first slide rail 13 may be a linear hole, which may be parallel to the upper section or the lower section of the fixing member 10, or may intersect with the upper section or the lower section of the fixing member 10, subject to the camera 40 being able to capture the animal's facial image. In some other embodiments, the first slide rail 13 may also be a curved hole opened on the surface of the fixing member 10, subject to the support assembly disposed in the first slide rail 13 being able to slide freely, which is not limited here.

[0128] Of course, the second slide rail 23 is similar to the first slide rail 13, and can be a linear hole or a curved hole opened on the surface of the fixing member 10. When the second slide rail 23 is a linear hole, it can be perpendicular to the first slide rail 13 or not.

[0129] In summary, in the technical solution of the first animal facial image acquisition device, when adjusting the shooting range of the camera 40, it can be adjusted in any of the following four ways:

[0130] The first mode: the first sliding member 21 can slide along the first sliding rail 13, thereby driving the support plate 22, the orientation adjustment component 30 and the camera 40 disposed on the first sliding member 21 to move;

[0131] The second mode: the second sliding member 31 can move along the second sliding rail 23, thereby driving the orientation adjustment member 32 and the camera 40 to move;

[0132] The third method: adjusting the angle of the angle adjustment member 322 to drive the camera 40 to rotate;

[0133] The fourth method: a combination of at least two of the above three methods, for example, the first method and the second method are combined to adjust the shooting range of the camera 40; or the first method and the third method are combined to adjust the shooting range of the camera 40; or the second method and the third method are combined to adjust the shooting range of the camera 40; or the first method, the second method and the third method are combined to adjust the shooting range of the camera 40.

[0134] It is worth noting that the execution order of the first method, the second method and the third method in the fourth method is not limited.

[0135] Furthermore, in order to expand the shooting range of the camera 40, a camera connector may be provided between the camera 40 and the angle adjustment member 322. The camera connector may also be a retractable structure, which is used to further expand the range of motion of the camera 40.

[0136] Figure 5 and Figure 6 The schematic diagram shows the structure of the second animal facial image acquisition device provided by the embodiment of the present invention at different angles.

[0137] When the fixing member 10 is mounted on the neck of an animal, the fixing member 10 may further include an annular fixing member and a cover connected to the annular fixing member, wherein the cover is used to accommodate the head of the animal, and the support assembly 20 is arranged at one end of the cover away from the annular fixing member, and the first direction is the direction along the side wall of the cover.

[0138] In this embodiment, in order to improve the wearing comfort of the animal, the annular fixing member can be a circular annular fixing member 11, the cover body can be a hollow frustum-shaped cover body 12, and the first direction is the circumferential direction along the side wall of the cover body.

[0139] The annular fixing member 11 and the hollow frustum-shaped cover 12 connected to the annular fixing member 11, the hollow frustum-shaped cover 12 is used to accommodate the head of the animal, and the support assembly 20 is arranged at the end of the hollow frustum-shaped cover with a larger opening.

[0140] Specifically, the openings at both ends of the hollow frustum-shaped cover 12 are of different sizes. The end of the hollow frustum-shaped cover 12 with a smaller opening is connected to one end of the annular fixing member 11. The annular fixing member 11 is used to be mounted on the neck or back of an animal. The hollow frustum-shaped cover 12 has a accommodating cavity for accommodating the head of an animal.

[0141] Since animals are afraid of objects protruding in front of them, in order to prevent animals from avoiding, running around and moving around due to fear when wearing the animal facial image acquisition device, as a most preferred solution, a first slide rail 13 can be set along the first direction on the surface of the hollow frustum-shaped cover body 12 close to the end with a larger opening; of course, the first slide rail 13 can also be set along the first direction on the surface of the hollow frustum-shaped cover body 12 close to the end with a smaller opening or on the surface of the middle part between the end with a larger opening and the end with a smaller opening, which is not limited here.

[0142] The support assembly 20 is disposed on the first slide rail 13 , the orientation adjustment assembly 30 is slidably disposed on the support assembly 20 along a second direction, and the camera 40 is disposed on the orientation adjustment assembly 30 for capturing images of animal faces.

[0143] Specifically, the end with a larger opening of the hollow frustum-shaped cover 12 is defined as the lower bottom surface, the end with a smaller opening is defined as the upper bottom surface, and the surface area of ​​the hollow frustum-shaped cover 12 between the upper bottom surface and the lower bottom surface is defined as the side surface. The internal cavity of the hollow frustum-shaped cover 12 has a receiving cavity for receiving the head of the animal, and after the hollow frustum-shaped cover 12 is sleeved on the neck of the animal, the end with a smaller opening is located at the neck of the animal.

[0144] In this embodiment, the fan ring piece 121 is defined as follows Figure 7 The shape shown, on the fan ring piece 121, the distance between DD1 and the distance between EE1 are equal. If the straight line D1D and the extension line of the straight line E1E intersect at point O, then it can be known that O is the center of the circle corresponding to the fan ring piece DEE1D1, the radius between the definition point O and the arc DE is the minimum radius, and the radius between the definition point O and the arc D1E1 is the maximum radius. The fan ring pieces 121 described in this solution all refer to Figure 2 The shapes shown are not further explained below.

[0145] Furthermore, if Figure 5 and Figure 6 As shown, when the cover body is a hollow frustum-shaped cover body 12, the cover body may include a first fan ring segment 122 and a second fan ring segment 123, the maximum radius of the first fan ring segment 122 is greater than the maximum radius of the second fan ring segment 123, and the minimum radius is the same; the first fan ring segment 122 and the second fan ring segment 123 are connected end to end to form a hollow frustum.

[0146] In a most preferred solution, the first fan ring piece 122 and the second fan ring piece 123 can be connected end to end with the edge alignment at the minimum radius as the reference to form a hollow frustum, and the first slide rail 13 is set in the extra area of ​​the first fan ring piece 122 relative to the second fan ring piece 123 in the hollow frustum cover 12. Of course, the first slide rail 13 can also be set in the area where the second fan ring piece 123 is recessed relative to the first fan ring piece 122, which can be set according to the specific animal species. In some other embodiments, the first fan ring piece 122 and the second fan ring piece 123 can also be connected end to end with the edge alignment at the maximum radius as the reference to form a hollow frustum, or the first fan ring piece 122 and the second fan ring piece 123 are directly connected end to end to form a hollow frustum without alignment operation, so that the user can adjust the shape of the hollow frustum cover 12 according to different needs, and the support assembly 20 can be set on the first fan ring piece 122 or the second fan ring piece 123 or between the first fan ring piece 122 and the second fan ring piece 123.

[0147] When worn, as a most preferred solution, the first fan ring piece 122 can be located directly above or below the animal's head, so that the support assembly 20 disposed on the first slide rail 13, the orientation adjustment assembly 30 disposed on the support assembly 20, and the camera 40 disposed on the orientation adjustment assembly 30 can collect the animal's facial image near the animal's eyes. Of course, the first fan ring piece 122 can also be located in other orientations around the animal's head, and the orientation setting is based on the camera 40 being able to clearly capture the animal's facial image, which is not limited here.

[0148] In this embodiment, the material of the hollow frustum-shaped cover body 12 can be metal, plastic, synthetic rubber, etc., which is not limited here.

[0149] As a preferred solution, in order to reduce the weight of the hollow conical cover 12 and improve the wearing comfort of small animals, and at the same time taking into account the stability of the support assembly 20 when sliding on the first slide rail 13, the first fan ring piece 122 can be made of metal material and the second fan ring piece 123 can be made of soft rubber material.

[0150] like Figure 5 and Figure 6 In order to make the hollow frustum-shaped cover 12 suitable for small animals with different neck circumferences, the first fan ring piece 122 and the second fan ring piece 123 are connected by an adjustable connector, and the opening size of the hollow frustum-shaped cover 12 is adjusted by the adjustable connector, for example, the size of the circumference of the upper bottom surface of the hollow frustum-shaped cover 12 and / or the size of the circumference of the lower bottom surface of the hollow frustum-shaped cover 12 can be adjusted by the adjustable connector. The adjustable connector may include buckles, Velcro, etc.

[0151] Specifically, since the neck circumferences of small animals of different types are different, even for small animals of the same type, different breeds and different weights often result in different neck circumferences. In order to make the hollow frustum-shaped cover 12 have a wider range of applications, when the cover is a hollow frustum-shaped cover 12, the cover can also be composed of at least one fan ring piece 121, and the size of the hollow frustum-shaped cover 12 can be adjusted by increasing or decreasing the number of fan ring pieces to expand the scope of use of the animal facial image acquisition device.

[0152] It is worth noting that in order to reduce the difficulty of setting the first slide rail 13 on the hollow frustum-shaped cover 12 and improve the stability of the support assembly 20 sliding on the first slide rail 13, the first slide rail 13 is preferably set on one of the fan ring pieces, such as Figure 5 and Figure 6 The first slide rail 13 may be arranged on the first fan ring piece 122 at a preset distance from the end with a larger opening.

[0153] Specifically, Figure 8 As shown, the hollow frustum-shaped cover body 12 includes at least one fan ring piece 121 of the same size, and the at least one fan ring piece 121 is detachably connected end to end to form a hollow frustum; the first slide rail 13 can be set on any fan ring piece 121.

[0154] Specifically, at least one fan ring piece 121 can be connected end to end through an adjustable connecting piece to form a hollow frustum-shaped cover body 12. When adjusting the opening size of the hollow frustum-shaped cover body 12, it can be adjusted by reducing the number of fan ring pieces 121 used in the hollow frustum-shaped cover body 12, and can also be adjusted through an adjustable connecting piece.

[0155] The first slide rail 13 can be arranged at one end of the arc near the maximum radius of any sector ring piece 121 , such as the above-mentioned first slide rail 13 is arranged on a sector ring piece 121 at a preset distance from the lower bottom surface of the hollow frustum-shaped cover body 12 .

[0156] Of course, in some other embodiments, the hollow frustum-shaped cover body 12 can also be formed by other types of sheet structures. For example, the sheet structure can be an irregular graphic structure. As long as they can be interconnected to form a hollow frustum, they are within the protection scope of the present invention. For another example, the hollow frustum-shaped cover body 12 can be a hollow frustum that is not fully surrounded by one or more narrow sheet structures as brackets.

[0157] In some other embodiments, the hollow frustum-shaped cover 12 may also be a support structure, or the hollow frustum-shaped cover 12 may also be a support structure, and the support structure is covered with a covering, such as cloth, plastic cloth, iron sheet, etc. The above structures of the hollow frustum-shaped cover 12 are all within the protection scope of the present invention.

[0158] It is worth noting that the hollow frustum-shaped cover 12 does not only refer to the strict hollow frustum-shaped in Euclidean geometry, but any deviation within a predetermined range (the predetermined range is based on the ability to be placed around the neck of an animal) is within the protection scope of the present invention.

[0159] The support assembly 20 includes a first sliding member 21 and a support plate 22. The first sliding member 21 is disposed on the first slide rail 13 and is used to slide in the first slide rail 13. The support plate 22 is connected to the first sliding member 21, and the first sliding member 21 drives the support plate 22 to slide in the first slide rail 13. The support plate 22 is provided with a second slide rail 23 along the second direction; the orientation adjustment assembly 30 is disposed on the second slide rail 23.

[0160] The orientation adjustment assembly 30 includes a second sliding member 31 and an orientation adjustment member 32, and the orientation adjustment member 32 includes an extension member 321 and an angle adjustment member 322. The second sliding member 31 is disposed on the second slide rail 23, the extension member 321 is disposed on the second sliding member 31, the angle adjustment member 322 is connected to the extension member 321, the camera 40 is connected to the angle adjustment member, and the angle adjustment member 322 can adjust the rotation angle of the camera 40 connected thereto, so that the camera 40 rotates within a predetermined angle range, thereby enabling the camera 40 to capture the image of the animal's face.

[0161] like Figure 5 As shown, the first sliding member 21 may include a first sliding block 211 and a stabilizing block 212 .

[0162] Combination Figure 1 The support plate 22 is disposed between the first sliding block 211 and the first slide rail 13, and the first slide rail 13 is between the support plate 22 and the stabilizing block 212. The first sliding block 211 passes through the first slide rail 13 and the support plate 22 and is connected to the stabilizing block 212. When the first sliding block 211 slides to a fixed position along the first slide rail 13, the stabilizing block 212 can improve the stability of the first sliding block 211 relative to the first slide rail 13, so that the first sliding block 211 is not easy to fall off from the first slide rail 13; in addition, the stabilizing block 212 can also prevent the neck of the animal from being injured when the first sliding block 211 slides in the first slide rail 13.

[0163] As a preferred solution, the first sliding block 211 can be a screw, and the stabilizing block 212 can be a nut. When the first sliding block 211 slides to a fixed position along the first slide rail 13, the screw and the nut can be spirally connected to improve the stability of the first sliding block 211 relative to the first slide rail 13.

[0164] Further, similar to the above solution, the first slide rail and the second slide rail both include at least two different movement directions.

[0165] like Fig. 9 and Fig.10 As shown, when the second slide rail 23 is a linear slide rail, the support plate 22 is also provided with a third slide rail 24 in a direction parallel to the second slide rail 23; the first sliding member 21 is also simultaneously arranged on the third slide rail 24, so that the support plate 22 can move along the third slide rail 24 relative to the fixing member 10.

[0166] Specifically, since small animals are easily afraid of objects that protrude relative to their heads, which may cause them to dodge or move around, in order to reduce the fear and discomfort of small animals wearing the animal facial image acquisition device, the present embodiment can use the first sliding member 21 to set the support plate 22 as a sliding structure, and the protruding length of the support plate 22 relative to the fixing member 10 can be adjusted to a minimum.

[0167] Further, the first sliding member 21 may include two sliding blocks, the number of the third slide rails 24 is two, the two third slide rails 24 are arranged on both sides of the second slide rail 23, and the two sliding blocks are respectively arranged in the two third slide rails 24.

[0168] As a most preferred solution, the third slide rail 24 can be set parallel to the second slide rail 23, and the number of the third slide rails 24 can be the same as the number of sliding blocks included in the first sliding member 21, and the position of the third slide rail 24 is limited by the position of the sliding block in the first sliding member 21.

[0169] For example, when the first sliding member 21 includes two sliding blocks, the number of the third slide rails 24 is two, the two third slide rails 24 are arranged on both sides of the second slide rail 23, and the two sliding blocks are respectively arranged on the two third slide rails 24, and the distance between the two third slide rails 24 is always equal to the distance between the two sliding blocks. The support plate 22 can move relative to the fixing member 10 along the third slide rails 24 to adjust the protruding length of the support plate 22 relative to the fixing member 10 to reduce the fear of small animals.

[0170] exist Fig. 9 and Fig.10 In the technical solution, when adjusting the shooting range of the camera 40, it can be adjusted in any of the following five ways:

[0171] The first mode: the first sliding member 21 can slide along the first sliding rail 13, thereby driving the support plate 22, the orientation adjustment component 30 and the camera 40 disposed on the first sliding member 21 to move;

[0172] The second mode: the second sliding member 31 can move along the second sliding rail 23, thereby driving the orientation adjustment member 32 and the camera 40 to move;

[0173] The third method: adjusting the angle of the angle adjustment member 322 to drive the camera 40 to rotate;

[0174] Fourth mode: the first sliding member 21 can slide along the third sliding rail 24, so that the support plate 22 moves along the third sliding rail 24 relative to the fixing member 10, thereby driving the camera 40 to move;

[0175] The fifth method: a combination of at least two of the above four methods, for example, the first method and the second method are combined to adjust the shooting range of the camera 40; or the first method and the third method are combined to adjust the shooting range of the camera 40; or the first method and the fourth method are combined to adjust the shooting range of the camera 40; or the second method and the third method are combined to adjust the shooting range of the camera 40; or the second method and the fourth method are combined to adjust the shooting range of the camera 40; or the third method and the fourth method are combined to adjust the shooting range of the camera 40; or the first method, the second method and the third method are combined to adjust the shooting range of the camera 40; or the first method, the second method and the fourth method are combined to adjust the shooting range of the camera 40; or the first method, the third method and the fourth method are combined to adjust the shooting range of the camera 40, and so on.

[0176] It should be noted that the execution order of the first method, the second method, the third method and the fourth method in the fifth method is not limited.

[0177] Therefore, in this embodiment, the animal facial image acquisition device can adjust the shooting range of the camera 40 through multiple angles (for example, the camera 40 can be rotated to multiple angles) and multiple directions (for example, the movement mode of the camera 40 in the above-mentioned centralized method), so that the animal facial image acquisition device can capture animal facial images at multiple angles and directions without blind spots, which is suitable for more small animals and more acquisition scenes, and improves the clarity of the captured animal facial images and the convenience of capturing the animal facial images.
