[0037] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] The biggest difficulty in the existing pig physical scoring is that there is no forming equipment to evaluate pigs, and manual evaluation is required, which is time-consuming and labor-intensive. The use of depth cameras is costly and has weak industrial sustainability. The use of RGB requires the collection of multi-viewpoint data, and single-viewpoint data is prone to lack of key information, resulting in reduced estimation accuracy.

[0039] To solve the above problems, the following Figure 1-Figure 5 The utility model describes the automatic collection device for the body shape and appearance of pigs provided by the utility model.

[0040] In some embodiments, as Figures 1 to 5As shown, the automatic pig body shape and appearance acquisition device comprises a slide rail mechanism 1, a mobile mechanism 2, and an acquisition mechanism 3. The mobile mechanism 2 is slidably mounted on the slide rail mechanism 1. The acquisition mechanism 3 comprises a support assembly 33, a first image acquisition device 31, and a second image acquisition device 32. The support assembly 33 is connected to the mobile mechanism 2 and is formed with multiple extensions 34. The support assembly 33 is switchable between a retracted state and an extended state. Each extension 34 is provided with at least one first image acquisition device 31. The second image acquisition device 32 is mounted on the support assembly 33 and is used to locate the pig. In the retracted state, the multiple extensions 34 retract to the inside of the support assembly 33. In the extended state, the multiple extensions 34 extend to the outside of the support assembly 33, allowing the first image acquisition device 31 to move around the pig and acquire the pig's physical characteristics.

[0041] Specifically, the slide mechanism 1 provides a track for the mobile mechanism 2, ensuring smooth movement along the designated path. The slide rail can be designed in a linear, curved, or circular shape to accommodate different working environments and assessment requirements. The mobile mechanism 2 is the driving portion of the device, moving along the slide mechanism 1 and driving the acquisition mechanism 3 to adjust its position. The mobile mechanism 2 can be driven by a motor, pneumatically, or hydraulically to ensure stable and reliable movement. The acquisition mechanism 3 is responsible for capturing the pig's body shape and appearance. The support assembly 33 is connected to the mobile mechanism 2 and carries the first image collector 31 and the second image collector 32. The extensions 34 are variable components of the support assembly, which can be extended from the inside to the outside of the support assembly 33 to adjust the position of the first image collector 31. The first image collector 31 is used to capture the pig's body shape and appearance information, such as body contour and muscle distribution. Each extension 34 is equipped with at least one first image collector 31 to ensure comprehensive and multi-angle capture of the pig's body shape and appearance. The second image collector 32 is mainly used to locate the pig. It is usually installed in the center of the support assembly 33 so as to accurately determine the position and posture of the pig during the assessment process.

[0042] During use of this automatic pig body shape and appearance acquisition device, the moving mechanism 2 drives the acquisition mechanism 3 along the slide rail mechanism 1 to move above or in front of the pig. Initially, the support assembly 33 is in a retracted state, and the second image acquisition device 32 locates the pig and determines its position and posture. The support assembly 33 switches from the retracted state to the expanded state, and the multiple extensions 34 expand to the outside of the support assembly, allowing the first image acquisition device 31 to move around the pig. The first image acquisition device 31 begins operating, capturing the pig's body shape and appearance information from multiple angles. The captured image information is transmitted to the processing system for analysis and evaluation, resulting in a pig's body shape and appearance score or related parameters.

[0043] The utility model provides an automatic device for collecting the body shape and appearance of live pigs. By arranging a moving mechanism and a collecting mechanism on a slide rail mechanism, the moving mechanism is used to control the position of the collecting mechanism to adjust the position of the first image collector and the second image collector on the collecting mechanism, and the second image collector is used to position the live pig. The state switching of the support component is used to control the first image collector to extend to the outside of the support component so that the first image collector moves to the surroundings of the live pig, and the first image collector is used to collect the body shape and appearance of the live pig. The device can realize automatic data collection and screening based on the standard standing posture discrimination model of the breeding pig based on animal posture estimation technology, and reduce the influence of different body postures on the model. Then, combined with the characteristics of various body shape models of live pigs, the auxiliary reasoning and precise assessment model of the body shape and appearance of breeding pigs is trained to form a quantitative standard evaluation. Ultimately, intelligent evaluation of the body shape of breeding pigs is achieved.

[0044] In some embodiments, as Figure 4 and Figure 5 As shown, the support assembly 33 includes a mounting plate 331 (suction cup); each extension 34 includes an L-shaped bracket 341 (flexible) and a blocker 342. The L-shaped bracket 341 is secured to the mounting plate 331 via the blocker 342, which has an energized state and an energized state. In the energized state, the blocker 342 is configured to drive the L-shaped bracket 341 to rotate and extend to the outside of the mounting plate 331. In the energized state, the blocker 342 is configured to drive the L-shaped bracket 341 to retract to the inside of the mounting plate 331. The second image collector 32 is mounted on the mounting plate 331.

[0045] In this embodiment, the blocker 342 is a key component for controlling the rotation of the L-shaped bracket 341. It has an on state and an off state, and realizes the rotation of the L-shaped bracket 341 by controlling the on and off of the current.

[0046] When the blocker 342 is powered, it drives the L-shaped bracket 341 to rotate, extending it from the inside of the mounting plate 331 to the outside. This allows the first image collector 31, mounted on the L-shaped bracket 341, to move around the pig, capturing information about its shape and appearance from multiple angles. When the blocker 342 is powered off, it drives the L-shaped bracket 341 to rotate in the opposite direction, retracting it back inside the mounting plate 331. This design allows the image collection mechanism 3 to maintain a compact structure when not in use, facilitating storage and transportation.

[0047] It should be noted that, by controlling the blocker 342 , the extension ratio of the L-shaped bracket 341 to the outside can also be controlled to adjust the position of the first image collector 31 .

[0048] By controlling the rotation of the L-shaped bracket 341 through the blocker 342, the collection mechanism 3 can be flexibly switched from the contracted state to the expanded state. This design allows the device to adapt to different pigs and improves the accuracy and reliability of the assessment.

[0049] In some embodiments, as Figure 1 and Figure 2 As shown, the slide rail mechanism 1 includes a guide rail 11 and an electromagnetic induction plate 12. The guide rail 11 is used to connect the moving mechanism 2; the electromagnetic induction plate 12 is provided on the guide rail 11 along the extension direction of the guide rail 11. During the sliding process of the moving mechanism 2, the moving mechanism 2 corresponds to different positions on the electromagnetic induction plate 12.

[0050] In this embodiment, the guide rail 11 is the main component of the slide mechanism 1, providing a path for the sliding movement of the moving mechanism 2. The guide rail 11 is typically made of high-strength, wear-resistant materials to ensure smooth and accurate operation during long-term use. The shape and size of the guide rail 11 can be designed based on specific requirements and can be linear, curved, or circular to suit different working environments and assessment requirements.

[0051] In this embodiment, the guide rail 11 is specially designed with a structure for hooking the movable mechanism 2. This design allows the movable mechanism 2 to be securely connected to the guide rail 11 and guided by it to slide along a predetermined path. Furthermore, the surface of the guide rail 11 has been specially treated to reduce friction and wear, thereby improving sliding efficiency.

[0052] The electromagnetic induction sheet 12 is typically made of a non-magnetic material and coated with a conductive layer or a magnetic material layer to generate electromagnetic induction with the sensing elements in the movable mechanism 2. As the movable mechanism 2 slides, its internal sensing elements (such as magnetic sensors, Hall elements, etc.) correspond to different positions on the electromagnetic induction sheet 12. As the movable mechanism 2 slides, the sensing elements continuously receive electromagnetic signals from the electromagnetic induction sheet 12, thereby detecting the position and speed of the movable mechanism 2 in real time. This design not only improves the motion accuracy and stability of the device but also provides precise position information for subsequent image acquisition and data processing. By recording the movement trajectory and speed of the movable mechanism 2 on the guide rail 11, the relative positional relationship between the images captured by the first image collector 31 and the second image collector 32 at different positions can be more accurately calculated, thereby achieving a precise assessment of the pig's body shape and appearance.

[0053] In summary, the slide rail mechanism 1 in this embodiment provides stable and reliable motion support and accurate position detection function for the automatic collection device of pig body shape and appearance through the ingenious combination of the guide rail 11 and the electromagnetic induction sheet 12.

[0054] In some embodiments, as Figure 1 and Figure 2 As shown, a conductive member 13 electrically connected to the moving mechanism 2 is formed on the guide rail 11; the automatic collection device for the body shape and appearance of live pigs also includes: a power supply mechanism, which is electrically connected to the moving mechanism 2 and / or the collection mechanism 3 through the conductive member 13.

[0055] Among them, the power supply mechanism is the power source of the automatic pig body shape and appearance collection device. It is electrically connected to the mobile mechanism 2 and / or the collection mechanism 3 through the conductive member 13 to provide stable power support for these devices.

[0056] In some embodiments, the power supply mechanism utilizes an independent, pluggable power supply. This type of power supply is compact, lightweight, and easily portable and replaceable. When the power supply runs out or requires maintenance, the user can simply unplug the power supply from the device and replace it with a new one, ensuring normal operation of the device.

[0057] In other embodiments, the power supply utilizes an uninterruptible power supply (UPS). A UPS is a device that provides continuous, stable power. If the external power supply is interrupted or abnormal, it automatically switches to internal battery power to ensure the device's power supply is not affected. This design is particularly important for devices that automatically collect information about pig body shape and appearance, which require long-term continuous operation.

[0058] Regardless of the power supply method, the power supply mechanism can provide power to the first image collector 31, the second image collector 32, the mobile mechanism 2, and other devices. After receiving sufficient power support, these devices can operate stably and complete their respective tasks, thereby achieving accurate assessment of the pig's body shape and appearance.

[0059] It should be noted that the conductive member 13 is generally provided at the end of the guide rail 11. At the same time, a rotating shaft can also be provided at the end of the guide rail 11. The rotating shaft is used to fix the collection of video transmission wires, and the conductive member 13 is used to slide to the end for automatic charging.

[0060] In some optional embodiments, such as Figure 1 and Figure 2 As shown, the guide rail 11 is provided with a drainage hole. The main function of the drainage hole is to drain water. During daily activities such as spray disinfection and floor cleaning in the pig farm, water stains may accumulate near the guide rail 11. If the water stains cannot be drained for a long time, the guide rail 11 may rust and corrode, and even affect the normal operation of the moving mechanism 2. The design of the drainage hole can ensure that the water stains are drained in time, keeping the guide rail 11 dry and clean.

[0061] In addition to drainage, drainage holes also help maintain pig house hygiene. By draining water stains in a timely manner, the growth and spread of pathogens such as bacteria and viruses can be reduced, providing a healthier and safer growth environment for pigs.

[0062] The location of the drainage holes needs to be carefully selected to ensure they are fully effective. Typically, drainage holes are located at the bottom or side of the guide rail 11 to allow for smooth drainage of water. The connection between the drainage holes and the pig house drainage system also needs to be considered to ensure that the drained water is drained smoothly into the sewer or sump.

[0063] The number and size of drainage holes should also be designed based on actual conditions. If the guide rail 11 is long or there are a lot of water stains in the pig house, the number and size of drainage holes can be appropriately increased to improve drainage efficiency. However, care should be taken to avoid excessive drainage holes, as this will affect the structural strength and stability of the guide rail 11.

[0064] In order to prevent the drainage holes from being blocked by debris, a filter net can be placed around them or other anti-clogging measures can be adopted. This can ensure that the drainage holes are always unobstructed, providing a strong guarantee for the cleanliness and hygiene of the pig house.

[0065] In some embodiments, as Figure 1 and Figure 2 As shown, the slide rail mechanism 1 further includes: a connecting component 14 , one end of which is connected to the top space of the pig farm, and the other end is connected to the guide rail 11 .

[0066] In this embodiment, the connection assembly 14 is typically made of high-strength, corrosion-resistant materials such as stainless steel and aluminum alloy to ensure it can withstand various stresses and environmental changes during use. The design of the connection assembly 14 also takes into account ease of installation and maintenance, allowing staff to easily perform installation, commissioning, and repairs. The provision of a wire hole 141 in the connection assembly 14 is a very practical design. The primary function of the wire hole 141 is to provide a channel for the wiring required by various devices (such as network cables and power cables), thereby avoiding the disorganization and safety hazards of wiring within the pig farm. Through the wire hole 141, staff can neatly route various wires within the connection assembly 14 and guide them from one end of the guide rail 11 to the other. This not only reduces the interference of the wires with the pig farm environment but also improves the safety and reliability of the wires. The design of the wire hole 141 also facilitates maintenance and replacement of the wires, allowing staff to easily operate them when necessary.

[0067] In some embodiments, as Figures 1 to 3As shown, the moving mechanism 2 includes a guide 21, rollers, a drive assembly 22, and a lifting assembly 23. The guide 21 is adapted to and mounted on the guide rail 11, with the rollers disposed between them. The drive assembly 22 is connected to the guide 21, and the lifting assembly 23 is detachably connected to the drive assembly 22. The two ends of the lifting assembly 23 are connected to the drive assembly 22 and the collection mechanism 3, respectively. The drive assembly 22 is used to drive the lifting assembly 23 upward and downward, and the rollers to rotate.

[0068] The guide 21 is the key connecting component between the moving mechanism 2 and the guide rail 11. It ensures smooth and accurate movement of the moving mechanism along the guide rail 11. The guide 21 is compatible with the guide rail 11, meaning its shape, size, and material are carefully designed to ensure a tight fit and smooth sliding. Furthermore, the guide 21 is fixed to the guide rail 11 by being hung thereon, a design that is both stable and easy to install and maintain.

[0069] The drive assembly 22 is the power source for the mobile mechanism 2, responsible for providing the necessary force and motion to drive the entire mechanism along the guide rails and achieve the lifting function. The drive assembly 22 is connected to the guide member 21 and is responsible for driving the rotation of the rollers, thereby propelling the entire mobile mechanism forward or backward on the guide rails. Furthermore, the drive assembly 22 not only drives the rotation of the rollers but also drives the lifting and lowering movement of the lifting assembly 23. This versatility enables the mobile mechanism to achieve precise horizontal and vertical movement as needed. The lifting assembly 23 is a key component connecting the drive assembly 22 and the collection mechanism 3, responsible for adjusting the height of the collection mechanism 3 as required. The lifting assembly 23 is connected to the drive assembly 22 in a liftable manner, meaning it can move freely in the vertical direction according to control commands. Furthermore, the two ends of the lifting assembly 23 are connected to the drive assembly 22 and the collection mechanism 3, respectively, ensuring effective force transmission and precise adjustment of the collection mechanism's position.

[0070] By adjusting the height of the collection mechanism 3 , the lifting assembly 23 makes the collection process more flexible and adaptable to collection requirements at different heights.

[0071] The driving component 22 includes a first driving member and a second driving member. The first driving member is connected to the roller for driving the roller to rotate. The second driving member is connected to the lifting component 23 for driving the lifting component 23 to move up and down.

[0072] Specifically, the primary function of the first drive element is to drive the roller to rotate. By establishing a transmission connection with the roller, the first drive element provides the necessary power to enable the roller to roll on the guide rail 11, thereby driving the entire moving mechanism 2 along the guide rail. The first drive element typically utilizes a high-torque, low-noise motor or reducer combination to ensure smooth and reliable rotation of the roller. Furthermore, the transmission connection may utilize structures such as gears, belts, or chains to achieve efficient power transmission.

[0073] Unlike the first drive element, the second drive element is responsible for driving the lifting assembly 23 in vertical motion. By establishing a transmission connection with the lifting assembly 23, the second drive element controls the vertical movement of the lifting assembly, thereby enabling precise adjustment of the height of the collection mechanism 3. The second drive element also requires a suitable motor or reducer combination to meet the load and speed requirements of the lifting assembly. The transmission connection may utilize a screw, chain, hydraulic, or pneumatic drive, depending on the design and application of the lifting assembly.

[0074] This dual-drive design enables the mobile mechanism 2 to handle both horizontal and vertical motion during operation. The first drive ensures smooth movement along the guide rails, while the second drive adjusts the height of the collection mechanism as needed. This collaborative approach significantly improves the flexibility and accuracy of the collection process, making the automated assessment of pig shape and appearance more efficient and reliable.

[0075] It should be noted that the first and second drive members can be motors. The first drive member can guarantee a distance of 400 meters and a movement speed of 5-10 m / min. The second drive member can reach a height of 0.2-0.8 m and a lifting speed of 0.9-1.2 m / min. Collection mechanism 3 can be set to a maximum of 256 preset positions, with the preset positions spaced no less than 0.1 m apart.

[0076] In some embodiments, as Figures 1 to 3 As shown, a guide rail baffle 15 is provided on the edge of the guide rail 11; the guide rail baffle 15 is used to cooperate with the guide rail 11 to limit the guide member 21. That is, the two side or upper edges that may come into contact with the guide member 21. This layout enables the guide rail baffle to directly physically limit the guide member 21, preventing it from deviating from the predetermined path or accidentally falling off during movement. The main function of the guide rail baffle 15 is to cooperate with the guide rail 11 to limit the guide member 21. By limiting the movement range of the guide member 21 in the horizontal and vertical directions, the guide rail baffle ensures that the mobile mechanism 2 can run along a predetermined and safe path. This is crucial to prevent the mobile mechanism from being damaged or affecting other equipment due to excessive movement.

[0077] In addition to the limiting function, the guide rail baffle 15 also has a certain safety protection function. In extreme cases, if the mobile mechanism loses control due to a fault or other reasons, the guide rail baffle 15 can serve as a barrier to reduce or avoid damage to surrounding equipment and personnel.

[0078] In a specific embodiment, the first image collector 31 is an appearance capture camera, and the second image collector 32 is an individual capture camera.

[0082] In summary, the automatic collection device for the body shape and appearance of live pigs provided by the embodiment of the present invention utilizes a multi-viewpoint high-definition video collection device and combines it with a corresponding body appearance assessment method to achieve automatic scoring of the body shape and appearance of live pigs. The device realizes the deployment of the monitoring range through a movable slide rail. During the actual breeding process, the individuals in the unconnected sheds and pens are calibrated, the individual capture camera realizes the individual positioning of the pigs, the appearance collection camera realizes the multi-viewpoint visual data collection, and the individual body appearance scoring of live pigs is realized through a fixed body appearance scoring algorithm. The users are mostly breeding pig farms, which closely monitor breeding sows and boars. The device can break the current situation of breeding pig body appearance scoring being labor-intensive, time-consuming, and labor-intensive, and provide an information-based solution for breeding pig body appearance scoring.

[0083] In addition, after the breeding pig farm installs this device, it is necessary to connect the information control system to the local network to realize the online update and synchronization of the path planning model and the physical appearance scoring model. The farm staff can set different preset points through the information system or input the corresponding individual pigs to set the operation.

[0084] After a job is set, a collection operation is triggered at a fixed time. The mobile data collection system collects data from the job target in sequence. The collected data is calculated by the edge terminal and the indicator value is given in real time. During idle time, the usage log is uploaded to automatically update the appearance scoring model, providing standardized intelligent equipment for physical appearance assessment and genetic evaluation of breeding pigs.
