[0003] Currently, the main method is to apply a standard pain stimulus and then look up the pressure difference between the animal's two feet in a reference table to obtain the actual pain value. However, due to the randomness of the animals, the accuracy of this method is poor. Summary of the Invention

[0023] In some embodiments, obtaining the actual pain value based on the first pain value data set includes the following steps:

[0026] T10. Obtain the degree of whitening of animal feet based on visual inspection equipment;
[0027] T20. Based on the degree of whitening of the animal's feet, the sixth data group was obtained; the data in the sixth data group corresponded one-to-one with the data in the first pain value data group, and the two corresponding data were obtained at the same time.

Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.
[0045] On the one hand, embodiments of this application provide a bipedal balance test method; please refer to [link to relevant documentation]. Figure 1 , Figure 1 This is a flowchart illustrating a bipedal balance test method provided in some embodiments of this application, including the following steps:
[0046] S10. After the animal is in place, obtain multiple pressure differences between the two feet within the first preset time period to obtain the difference range (a1, a2).
[0047] In S10, "animal placement" refers to placing the animal in the test environment and allowing it to adapt. Once the animal has adapted, it is considered "placed." Depending on the specific test content, the bipedal pressure difference can be either the pressure difference between the hind and front legs. The bipedal pressure difference is primarily determined by acquiring the pressure of both legs in the area where pressure sensors are installed, and then calculating the pressure difference. Within the first preset time period, multiple bipedal pressure differences will be obtained; the minimum value a1 and the maximum value a2 are primarily selected. "Multiple bipedal pressure differences" refers to at least two.
[0048] S20. Apply pain stimulation to the animal's feet.
[0049] In S20, the painful stimulus can be a von Frey wire measuring the mechanical pain threshold or a hot / cold plate measuring the temperature pain threshold.
[0050] S30. Obtain a first data set B={b1,b2,...,bn} that includes multiple bipedal pressure differences within a second preset time period.
[0051] In S30, depending on the specific circumstances, the first data set can be acquired either simultaneously with the application of the pain stimulus or immediately after the stimulus ends. The second preset time period can be the same length as the first preset time period, or they can be different lengths. When the second preset time period and the first preset time period are different lengths, the second preset time period can be longer or shorter than the first preset time period. The more bipedal pressure difference values there are, i.e., the more data in the first data set, the more accurate the subsequent test results will be.
[0052] S40. Correct multiple bipedal pressure difference values to obtain a corrected data set, which mainly includes the following steps:
[0053] S401. Obtain the bipedal pressure difference values of the first data set that are greater than or equal to a2, and obtain the second data set C={c1,c2,...,cm}.
[0054] In S401, the second data group includes at least one data point. If the second data group is empty, the test process fails and no further steps are performed. Where m ≤ n.
[0055] S402. Based on the second data set, obtain the third data set D=C-a1={c1-a1,c2-a1,...,cm-a1}, and add the data in the third data set to the correction data set.
[0056] In S402, the third data group consists of each data point in the second data group minus the value of a1. The amount of data in the third data group is the same as that in the second data group. Before the data from the third data group is added to the correction data group, the correction data group can be empty or it can include data obtained through other means.
[0057] S50. Based on the corrected data set, obtain the corresponding first pain value data set, and then based on the first pain data set, obtain the actual pain value.
[0058] In S50, obtaining the corresponding first pain value data group based on the corrected data group means obtaining a first pain value data for each data point in the corrected data group. This process can be implemented using existing technologies. The amount of data in the first pain value data group is the same as the amount of data in the corrected data group. Obtaining the actual pain value based on the first pain data group means obtaining a relatively accurate pain value based on multiple pain data points. This process can be achieved by taking the median of multiple pain data points or by calculating the value by assigning weights to multiple different pain data points.
[0059] In the above embodiment, the state of the animal before the application of pain stimulus is first obtained to obtain the range of pressure difference between the two feet under normal conditions. Then, based on the range of pressure difference between the two feet under normal conditions, multiple data after the application of pain stimulus are filtered. Then, the filtered data is further corrected so that the data in the final corrected data set is more consistent with the data values generated by the animal after the application of pain stimulus. Then, the actual pain value is obtained based on the corrected data set.
[0060] By setting up the above embodiments, the obtained pressure difference value of the two feet can be more closely related to the situation of being subjected to pain stimulation after correction, which can reduce the poor accuracy of the measurement results caused by the randomness of the animal, and thus make the final actual pain value more accurate.
[0061] In some embodiments, after obtaining the second data set in step S40 and before obtaining the corresponding first pain value data set based on the corrected data set in step S50, the following steps are also included:
[0062] S403. Determine whether the amount of data in the second data group exceeds the first preset quantity.
[0063] In S403, in order to obtain a certain number of first pain value data in the future, it is necessary to ensure that the corrected data set also meets a certain requirement.
[0064] S404. If it is determined that the amount of data in the second data group exceeds the first preset quantity, then proceed to step S50.
[0065] In S404, the subsequent S50 proceeds normally, that is, the data in the third data group is added to the correction data group, and then the corresponding first pain value data group is obtained based on the correction data group.
[0066] S405. When it is determined that the amount of data in the second data group does not exceed the first preset quantity, the pressure difference between the two feet that is greater than a1 and less than a2 in the first data is obtained, and the fourth data group E={e1,e2,...ei} is obtained.
[0067] In step S405, the fourth data set and the second data set are not necessarily related, where i≤n.
[0068] S406. Based on the fourth data set, obtain the fifth data set F=E-a1={e1-a1,e2-a1,...,ei-a1}, and add the data in the fifth data set to the correction data set.
[0069] In S406, the fifth data group is the data after subtracting the a1 value from each data in the fourth data group, and the amount of data in the fifth data group is the same as the amount of data in the fourth data group.
[0070] In the above embodiments, there is no necessary connection between steps S403-S406 and step S402. Step S402 may be performed before steps S403-S406, after steps S403-S406, or simultaneously.
[0071] With the settings of the above embodiments, if the amount of data in the second data group is small after obtaining the second data group, the amount of data in the first pain data group obtained subsequently will also be small. This may lead to a large deviation in the actual pain value obtained subsequently. In the above embodiments, by obtaining a fourth data group to increase the amount of data in the first pain data group, the deviation of the actual pain value obtained subsequently can be smaller, and the test results can be more accurate.
[0072] In some embodiments, in step S50, obtaining a corresponding first pain value data set based on the corrected data set, and then obtaining the actual pain value based on the first pain value data set, includes the following steps:
[0073] S501. Based on the third data group, obtain the corresponding first pain value data group, and then obtain the specific first pain value.
[0074] S502. Based on the fifth data group, obtain the corresponding first pain value data group, and then obtain the specific second pain value.
[0075] S503. Obtain the actual pain value = first pain value * z1 + second pain value * z2, where z1 is the first preset weight, z2 is the second preset weight, z1 + z2 = 1, z1 > z2.
[0076] In the above embodiments, because the amount of data in the third data group is relatively small, if the average value of the corrected data group, including the third and fifth data groups, is simply obtained when a fifth data group is introduced, although the deviation of the final actual pain value is reduced, a certain degree of bias will still occur. Therefore, by assigning a heavier weight to the more authoritative first pain value, the final actual pain value can be made more accurate.
[0077] In some other embodiments, in step S50, obtaining the actual pain value based on the first pain value data set includes the following steps:
[0078] The median of all data in the first pain value data group is used as the actual pain value.
[0079] By implementing the above-described embodiments, the calculation of actual pain values can be made more robust and reliable by avoiding significant impact from individual abnormal data. This method of using the median as the actual pain value reduces errors caused by data fluctuations to a certain extent, improving the accuracy and stability of the measurement results.
[0080] Please see Figure 2 , Figure 2 This is a flowchart illustrating a bipedal balance testing method provided in some other embodiments of this application. In some of these embodiments, before obtaining the actual pain value based on the first pain value data set in step S50, the following steps are also included:
[0081] T10. Obtain the degree of whitening of animal feet based on visual inspection equipment.
[0082] T20. Based on the whitening of the animal's feet, the sixth data group was obtained; the data in the sixth data group corresponded one-to-one with the data in the first pain value data, and the two corresponding data were obtained at the same time.
[0083] In steps T10 and T20, while measuring the pressure difference between the animal's two feet using a pressure testing device, a second pain value is simultaneously acquired through a visual detection device for each pressure difference value. The acquisition times are the same. After filtering the pressure difference values, the data that is filtered out is deleted, so that the amount of data in the sixth data group, which includes multiple second pain value data, is the same as the amount of data in the first pain value data group, and they correspond one-to-one.
[0084] The sixth data set obtained through visual inspection equipment is an existing technology. The general process involves using the equipment to acquire images of an animal's feet, analyzing the color features of the feet in the images using image recognition technology, and converting the degree of paleness of the feet into corresponding pain value data based on a pre-defined correspondence between color and pain value. For example, a color database can be pre-established, where different color ranges correspond to different pain value intervals. After the visual inspection equipment acquires images of the animal's feet, it analyzes the range of colors within the images to determine the corresponding pain value data.
[0085] T30. Calculate the difference between the data in the sixth data group and the corresponding data in the first pain value data group.
[0086] In T30, the amount of data in the first pain value data group is the same as the amount of data in the sixth data group, so the amount of data for the difference between the two is also the same as the amount of data in the two data groups mentioned above.
[0087] T40. If the difference calculated in step T30 is greater than the first preset value, then the corresponding data in the first pain value data group will be deleted.
[0088] By using the above-described embodiments, a sixth data set is obtained from a conventional visual inspection device with relatively blurry test results. This sixth data set is then compared with the first pain value data set. Data with large deviations are further filtered, and then the actual pain value is obtained from the filtered first pain value data set. This approach makes the final actual pain value more accurate and improves the test results.
[0089] In some embodiments, the second preset time period is ≥ 2 * the first preset time period.
[0090] In the above embodiments, the length of the second preset time period is greater than or equal to twice the length of the first preset time period. On the one hand, this can make the length of the first preset time period shorter, thereby improving the efficiency of the entire test. On the other hand, it can make the amount of data in the first data set obtained after applying pain stimulation to the animal's feet more, which can better serve the subsequent screening and correction processes. In this way, the final actual pain value can be obtained through more data, resulting in higher test accuracy.
[0091] In some embodiments, step S50, obtaining the corresponding first pain value data set based on the corrected data set, includes the following steps:
[0092] K10: Compare each data value in the corrected data set with a preset pain level rating scale, which includes multiple pain intensity ranges and corresponding pressure differences.
[0093] K20: Map each data value to the pressure difference corresponding to its respective pain intensity range to generate the first pain value data group.
[0094] The above-described embodiments allow for the effective correlation between the data in the corrected data set and the pain level rating scale, transforming the data into meaningful pain pressure differences. This approach makes the abstract data in the corrected data set intuitive and understandable, facilitating subsequent calculations of actual pain values.
[0095] On the other hand, embodiments of this application provide a bipedal balance testing system, including a memory and a processor. The memory stores a computer program, and the processor executes the computer program to implement the bipedal balance testing method of any of the above embodiments.
[0096] This application also provides a computer storage medium storing a computer program, which is executed to implement the bipedal balance test method of any of the above embodiments.

The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
