[0043] In the field of animal behavior research, monitoring and recording animal behavior is crucial. Traditional video recording has some limitations when monitoring animal behavior, such as the limitations of fixed angles and limited fields of view. These limitations may result in missing important behavioral details or failing to fully record the full range of animal activities.

[0044] In order to meet the demand of monitoring animal behavior without omission, an animal behavior reconstruction system is disclosed in the related art, the system includes at least two cameras, a fixing frame, a timer and a terminal device; the fixing frame includes a preset number of fixed pillars, and each camera is respectively set at a preset installation position on each fixed pillar; the timer is respectively connected to the terminal device and each camera, and the terminal device is respectively connected to each camera, and each camera is respectively set at a different installation position of the fixing frame, and the camera is used to receive the waveform signal sent by the timer, collect animal behavior data based on the waveform signal, and send the animal behavior data to the terminal device; the terminal device is used to store at least two received animal behavior data, and determine three-dimensional reconstruction data based on each animal behavior data. The problem with the related art is that the camera is fixed by multiple fixed pillars, and the camera is easy to shake, which affects the imaging quality of the camera.

[0045] In order to reduce the shaking of the camera and improve the imaging quality of the camera, Figure 1-4 As shown, an embodiment of the present disclosure provides a connection assembly 100, which includes a connector 110 and a plurality of connection rods 120, wherein the connector 110 is provided with a plurality of connection mating portions 111; the plurality of connection rods 120 correspond to the plurality of connection mating portions 111 of the connector 110, one end of the connection rod 120 is connected to a connection mating portion 111 of the connector 110, and the other end is suitable for connecting to at least one fixed object.

[0046] The connection component 100 is used to fix a plurality of fixed objects. For example, the fixed object is a camera fixing component 200 .

[0047] The connection assembly 100 is provided with a plurality of connection matching parts 111, and illustratively, the connection matching parts 111 are jacks. The connection assembly 100 also includes a plurality of connection rods 120, one end of the connection rods 120 matches with the connection matching parts 111, and the other end of the connection rods 120 is suitable for connecting a fixed object. Exemplarily, one end of the connection rod 120 is inserted into the jack of the connector 110. The connection assembly 100 includes a plurality of connection rods 120, and the plurality of connection rods 120 matches with the plurality of connection matching parts 111 of the connection matching parts 111 in a one-to-one correspondence. In this way, a plurality of fixed objects can be connected together through the connector 110 and the plurality of connection rods 120.

[0048] The connection assembly 100 provided in the embodiment of the present disclosure can be used to connect multiple fixed objects together, and the fixed objects are not easy to shake. When the multiple fixed objects are camera fixing assemblies 200, the connection assembly 100 provided in the embodiment of the present disclosure can significantly enhance the stability of the camera and effectively reduce the shaking of the camera during the recording process. The shaking of the camera is reduced, so that the camera can obtain clear and stable images when recording animal behavior, and more accurately record and analyze the behavioral details of the animal.

[0049] Optionally, the connector 110 includes four side surfaces, each of which is provided with a connection fitting portion 111 ; the connection assembly 100 includes four connection rods 120 , and the four connection rods 120 are respectively connected to the four connection fitting portions 111 of the connector 110 .

[0050] With this setting, the observation field of the observed object is more comprehensive and there are fewer blind spots.

[0051] Optionally, the first end of the connecting rod 120 is plug-fitted with the connecting fitting portion 111 .

[0052] This arrangement makes it easy to disassemble and assemble the connecting rod 120 and the connector 110 .

[0053] Optionally, the first end of the connecting rod 120 is threadedly connected to the connecting fitting portion 111 .

[0054] One of the first end of the connecting rod 120 and the connecting fitting portion 111 is provided with a threaded hole, and the other is configured with an external thread. The connecting rod 120 or the connector 110 is rotated to complete the disassembly and assembly between the connecting rod 120 and the connector 110. In this way, the connection between the connecting rod 120 and the connector 110 is more secure, and this way is also easy to operate.

[0055] Optionally, the second end of the connecting rod 120 is configured with an external thread or an internal thread, and the connecting rod 120 is suitable for being threadedly connected to a fixed object.

[0056] This arrangement makes it easier for the user to connect the fixed object to the second end of the connecting rod 120 .

[0057] Optionally, the length of the connecting rod 120 is adjustable.

[0058] When the size of the observed object is different, the distance between the fixed object and the observed object can be adjusted to a suitable range by adjusting the length of the connecting rod 120. With such a setting, the applicability of the connection component 100 can be improved, so that the connection component 100 can be applied to more scenes.

[0059] Optionally, the connecting rod 120 includes a plurality of short rods 121 connected to each other, and the length of the connecting rod 120 can be adjusted by connecting different numbers of short rods 121 .

[0060] As a way to adjust the length of the connecting rod 120, the connecting rod 120 includes a plurality of short rods 121, which are plug-fitted or screw-fitted. When the length of the connecting rod 120 needs to be changed, short rods 121 of different lengths are replaced or different numbers of short rods 121 are assembled. In this way, the length of the connecting rod 120 is easy to adjust and the operation is convenient.

[0061] Optionally, the connecting rod 120 includes an outer cylinder 123 and an inner cylinder 122 , at least a portion of the inner cylinder 122 is located inside the outer cylinder 123 , and the length of the connecting rod 120 is adjusted by moving the inner cylinder 122 .

[0062] As another way to adjust the length of the connecting rod 120, the connecting rod 120 includes an inner tube 122 and an outer tube 123. When the inner tube 122 extends from the outer tube 123, the length of the connecting rod 120 increases, and when the inner tube 122 retracts into the outer tube 123, the length of the connecting rod 120 decreases. In this way, the user can adjust the length of the connecting rod 120 more conveniently.

[0063] Optionally, the connector 110 is provided with a harness fixing portion 112 .

[0064] A plurality of fixed objects are located outside the circumference of the connector 110, and the observation object is usually located above or below the connector 110. The connector 110 is provided with a harness fixing portion 112, which facilitates the user to connect the harness to the observation object. The harness extending from the harness fixing portion 112 to the observation object is not easy to block the fixed object.

[0065] Taking a usage scenario as an example, the observation object is an animal in an observation cage. The fixed object is a camera fixing assembly 200, and the camera fixing assembly 200 is connected to at least one camera. Multiple camera fixing assemblies 200 are arranged on the circumferential outer side of the observation cage. The connector 110 of the connection assembly 100 fixes the multiple camera fixing assemblies 200 together through multiple connecting rods 120, and the connector 110 is located directly above the observation cage. The wiring harness for detecting animal electrical signals extends from the wiring harness fixing portion 112 of the connector 110 to the animal in the observation cage.

[0066] Multiple cameras are located on the outer side of the observation cage, so that the animal can be observed in all directions without blind spots. The connection component 100 connects multiple camera fixing components 200 together, and the camera fixing components 200 are not easy to shake, and the camera effect is stable. The harness fixing part 112 is at a certain distance from each camera, and the harness hanging downward from the harness fixing part 112 will not block the camera.

[0067] Combination Figure 1-6 As shown, an embodiment of the present disclosure provides a camera bracket, which includes a plurality of camera fixing components 200 and the above-mentioned connecting component 100, wherein the plurality of camera fixing components 200 are suitable for being arranged on the peripheral side of the observation area, and each camera fixing component 200 is suitable for fixing at least one camera; and the connecting component 100 is used to connect the plurality of camera fixing components 200.

[0068] The camera bracket provided in the embodiment of the present disclosure includes two parts, one part is a plurality of camera fixing components 200, and the other part is the above-mentioned connecting component 100. When using the camera bracket, first place the plurality of camera brackets on the circumferential outside of the observed object. Then connect the plurality of camera fixing components 200 through the connector 110 and the plurality of connecting rods 120. The first end of each connecting rod 120 is connected to the fixture, and the second end is connected to a camera fixing component 200. In this way, each camera fixing component 200 is constrained by the connecting rod 120 along the radial direction of the observed object, and the camera fixing component 200 is not easy to shake.

[0069] The camera bracket provided by the embodiment of the present disclosure can ensure that the camera can cover a wider area and reduce blind spots by arranging multiple camera fixing components 200 on the periphery of the observation area, thereby improving the comprehensiveness and accuracy of monitoring; the use of the connecting component 100 can connect multiple camera fixing components 200 into a whole, which can not only enhance the stability of the entire bracket and reduce the shaking of the camera due to external factors (such as wind, vibration, etc.), but also keep the position of the camera stable and ensure the clarity of the shooting picture; the modular design of the camera fixing component 200 and the connecting component 100 makes the installation and disassembly of the entire bracket simple and quick. At the same time, due to the adjustability of the connecting component 100, the user can easily adjust the angle and position of the camera to meet different monitoring needs; the design of the camera bracket has good scalability. The user can increase or decrease the number of camera fixing components 200 as needed to cover a larger area or meet specific monitoring needs. In addition, the versatility of the connecting component 100 also enables other types of cameras or devices to be easily integrated into the bracket. By using standardized camera fixing components 200 and connecting components 100, production costs and maintenance costs can be reduced. At the same time, due to the modular design of the entire bracket, when a component fails, the user only needs to replace the component without replacing the entire bracket, thereby reducing maintenance costs. The simultaneous use of multiple cameras can provide redundancy and backup functions. When one camera fails, other cameras can continue to work, ensuring the continuity and reliability of the monitoring system.

[0070] Optionally, the camera fixing assembly 200 includes a fixing rod 210, an adjusting rod 220 and a camera base 230, wherein the fixing rod 210 is suitable for being arranged on the peripheral side of the observation area; the adjusting rod 220 is connected to the fixing rod 210 and the end thereof faces the preset observation area; and the camera base 230 is arranged at the end of the adjusting rod 220.

[0071] Take the example of a fixed rod 210 arranged vertically and an adjusting rod 220 arranged horizontally. The fixed rod 210 of the camera fixing assembly 200 serves as the main structure for fixing the camera, and its position is basically fixed during use. The adjusting rod 220 is connected to the fixed rod 210, and a free end of the adjusting rod 220 is the end, facing the preset observation area. The camera base 230 is arranged at the end of the adjusting rod 220. The camera base 230 is used to fix the camera. In this way, the camera is indirectly connected to the fixed rod 210 through the camera base 230 and the adjusting rod 220. With such a setting, the camera can be closer to the observed object than the fixed rod 210, which is beneficial to improving the imaging quality of the camera.

[0072] Optionally, the adjusting rod 220 can slide along the fixing rod 210 to adjust the position of the adjusting rod 220 on the fixing rod 210 .

[0073] For example, the fixing rod 210 is arranged vertically and the adjusting rod 220 is arranged horizontally. When the adjusting rod 220 slides along the fixing rod 210, the height of the adjusting rod 220 from the ground can be changed, thereby changing the height of the camera from the ground. This arrangement makes it convenient for users to adjust the height of the camera.

[0074] Taking the case where the fixed rod 210 is arranged horizontally and the adjusting rod 220 is arranged vertically as an example, the distance between the adjusting rod 220 and the observed object can be changed when the adjusting rod 220 slides along the fixed rod 210. With such an arrangement, it is convenient for the user to adjust the shooting distance of the camera.

[0075] Optionally, the camera fixing assembly 200 further includes a diverter 240 , which is provided with a first opening 241 and a second opening 242 , the fixing rod 210 passes through the first opening 241 , the adjusting rod 220 passes through the second opening 242 , and the adjusting rod 220 is connected to the fixing rod 210 via the diverter 240 .

[0076] The adjusting rod 220 is connected to the fixing rod 210 through the steering gear 240 , and the adjusting rod 220 and the fixing rod 210 are at a substantially vertical angle.

[0077] The fixed rod 210 penetrates into the first opening 241 of the steering gear 240, and the adjusting rod 220 penetrates into the second opening 242 of the steering gear 240. When the adjusting rod 220 slides relative to the steering gear 240, the adjusting rod 220 moves along a radial line of the fixed rod 210. When the adjusting rod 220 slides relative to the fixed rod 210 together with the steering gear 240, the adjusting rod 220 moves along the circumferential direction of the fixed rod 210. With such a setting, the height of the free end of the adjusting rod and the distance from the fixed rod 210 can be conveniently adjusted, so that the camera connected to the camera fixing assembly 200 has a better shooting distance and shooting angle.

[0078] Optionally, the camera base 230 is slidably disposed on the adjustment rod 220 .

[0079] In this way, the distance between the camera and the fixing rod 210 can also be adjusted by sliding the camera base 230, so that the camera is at a better shooting distance.

[0080] Optionally, the camera base 230 is rotatably disposed on the adjustment rod 220 .

[0081] When the camera base 230 is rotatable, the shooting angle of the camera can be adjusted by rotating the camera base 230. With such an arrangement, the adjustment range of the camera base 230 can be further increased, thereby improving the camera quality.

[0082] Optionally, at least a portion of the fixing rod 210 is a hollow structure.

[0083] At least part of the fixing rod 210 is a hollow structure, which can reduce the weight and cost of the fixing rod 210. On the other hand, the fixing rod 210 can be passed through the hollow structure part, which can make the wire harnesses connecting multiple cameras more neat and reduce the shielding of the cameras by the wire harnesses.

[0084] Optionally, the fixing rod 210 is arranged vertically, and the adjusting rod 220 is arranged horizontally.

[0085] When the fixing rod 210 is arranged vertically, it provides support force for the camera in the vertical direction. The connecting rod 120 of the connecting assembly 100 limits the fixing rod 210 in the radial direction. With such an arrangement, multiple cameras can be fixed in three-dimensional space at a relatively low cost.

[0086] Optionally, the camera fixing assembly 200 further includes a base 250 , which is provided with a mounting fitting portion; the bottom end of the fixing rod 210 is fixed to the mounting fitting portion of the base 250 .

[0087] The base is used to pre-fix the fixing rod 210 , and the mounting matching portion of the base is illustratively a socket, and the bottom end of the fixing rod 210 is inserted into the socket.

[0088] In the radial direction of the fixing rod 210, multiple fixing rods 210 are connected by the connecting assembly 100. In this way, the base, the fixing rod 210 and the connecting assembly 100 form a camera fixing assembly 200 that is easy to disassemble and assemble, has a stable structure, and can fix multiple cameras in three-dimensional space in a low-cost manner. With such a setting, the fixing effect of the camera fixing assembly 200 on multiple cameras can be further improved. In addition, since the camera fixing base pre-fixes the fixing rod 210, it is more convenient to assemble the camera fixing group.
