Abstract
Description
Technical Field
[0001] This utility model belongs to the field of animal husbandry technology, and is specifically applied to an intelligent device for measuring the body size and automatically calculating the weight of donkeys. Background Technology
[0002] In donkey farming, regular weight and size measurements are necessary for health management and growth analysis. Traditional methods for size measurement rely on manual labor using tools like measuring sticks and tape measures, which are time-consuming and prone to error. For weight measurement, weighing the donkey separately requires herding it to a weighbridge, easily triggering stress in the animal. Existing automated equipment is mostly designed for cattle and sheep and cannot adapt to the temperament and body characteristics of donkeys (such as lower shoulder height and unique body proportions). Furthermore, body size and weight data are stored separately, making growth performance analysis difficult. Summary of the Invention
[0003] To address the technical problems of low efficiency in body size measurement, difficult weighing operation, and inconvenient data integration in existing donkey breeding processes, this utility model provides an intelligent donkey weight and body size measurement device, including a weighing platform, an image acquisition module, a data processor, an automatic door device, and a control device. The weighing platform includes a steel rectangular frame with an anti-slip mat on top. Pressure sensors are respectively installed at the bottom of the four corners of the anti-slip mat. A fence is fixed around the top of the steel rectangular frame. A donkey entrance is set on the front side of the fence, and a donkey exit is set on the rear side of the fence.
[0004] The image acquisition module includes a first image acquisition camera and a second image acquisition camera. The first image acquisition camera is arranged at a certain height directly above the rectangular frame to acquire images of the donkey from above and obtain a top view.
[0005] The second image acquisition camera is mounted on a post, which is located on the side of the fence and at a certain distance from the fence. The second image acquisition camera is used to acquire images of the donkey from the side to obtain a side view.
[0006] Furthermore, the second image acquisition camera can slide up and down relative to the column.
[0007] Furthermore, the data processor includes a data conversion module, a noise reduction module, a data comparison module, and a data output module;
[0008] The data conversion module is used to convert the top view and side view into point cloud data, the noise reduction module performs noise reduction processing on the point cloud data, and the data comparison module is used to compare the pre-stored donkey data with the collected data to obtain body size parameters.
[0009] Furthermore, the noise reduction process includes eliminating interference points caused by tail swing.
[0010] Furthermore, the body size parameters include body height, hip height, body length, chest width, chest circumference, hip length, tube circumference, chest depth, and hip width.
[0011] Furthermore, the automatic door device includes an inlet door at the entrance of the donkeys and an outlet door at the exit of the donkeys. The inlet door and the outlet door are connected to a control device and are opened and closed automatically by electric control.
[0012] Furthermore, an RFID module is installed at the entrance gate, which is used to identify the donkeys by tag.
[0013] In this invention, the combination of a first image acquisition camera and a second image acquisition camera overcomes the field-of-view obstruction problem in existing measurement techniques, enabling the acquisition of more accurate dimensional information. The first and second image acquisition cameras can obtain detailed information on the thoracic cross-section, lumbar cross-section, and pelvic cross-section. Data capture, processing, and integration of the required body measurements significantly improve efficiency. Simultaneously, the use of pressure sensors distributed at the four corners to measure corresponding pressures eliminates errors caused by the donkey's movement during measurement, resulting in a more accurate determination of the donkey's weight.

[0015] Figure 2 This is a front view of the measuring device of the present invention;
[0016] Figure 3 This is a side view of the measuring device of the present invention. Detailed Implementation
[0017] See Figures 1-3 The intelligent measuring device for donkey weight and body size of this utility model includes a weighing platform 1, an image acquisition module 2, a data processor 3, an automatic door device 4, and a control device 5.
[0018] The weighing platform 1 includes a steel rectangular frame 11, on which an anti-slip mat 12 is laid. Pressure sensors 13 (not shown) are respectively installed at the bottom of the four corners of the anti-slip mat 12. A fence 14 is fixed around the top of the rectangular frame 11. The front of the fence 14 is provided with an entrance for the donkeys, and the rear of the fence 14 is provided with an exit for the donkeys. When the pressure sensor 13 detects that the weight is stable above 10 kg for 3 seconds, it can be considered that the donkey is fully standing.
[0019] The image acquisition module 2 includes a first image acquisition camera 21 and a second image acquisition camera 22. The first image acquisition camera 21 is positioned at a certain height directly above the rectangular frame 11 to capture images of the donkeys below from above, obtaining a top view. The second image acquisition camera 22 is mounted on a post 23, which is located on the side of the fence 14 at a certain distance from the fence 14. The second image acquisition camera 22 is used to capture images of the donkeys from the side, obtaining a side view. Preferably, the second image acquisition camera 22 can slide up and down relative to the post 23, thereby adjusting its position according to the donkey breed (such as Dezhou donkey or Guanzhong donkey).
[0020] The data processor 3 connects to the pressure sensor 13 and the image acquisition module 2 to acquire top and side views of the donkey. It analyzes the data from the pressure sensor 23, the top and side views, and performs spatial registration of the stereoscopic vision data. Specifically, the data processor 3 includes a data conversion module, a noise reduction module, a data comparison module, and a data output module. The data conversion module converts the top and side views into point cloud data. The noise reduction module performs noise reduction processing on the point cloud data, removing interference points such as tail swaying. The data comparison module compares pre-stored donkey data with the acquired data to obtain data such as body height, rump height, body length, chest width, chest circumference, rump length, cannon bone circumference, chest depth, and rump width.
[0021] The automatic door device 4 includes an inlet door 41 at the donkey's entrance and an outlet door 42 at the donkey's exit. The inlet door 41 and outlet door 42 are connected to a control device 5 and are electrically and automatically opened and closed. An RFID module is installed at the inlet door 41. The RFID module first identifies the donkey's tag. After successful identification, the inlet door 41 opens. Once the donkey enters the anti-slip mat 12, the inlet door 41 automatically closes. After measurement is completed, the outlet door 42 opens. After the donkey exits the rectangular frame 11, the outlet door 42 closes, and the measurement process begins for the next donkey.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
