[0026] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0027] refer to Figure 1-2 The specific embodiment of the present invention provides a method for measuring the bite of giant panda feces, comprising the following steps:

[0028] Step 1: Prepare the measuring plate;

[0029] Step 2: Place the collected bites on a measuring plate, and use the scale 2 on the measuring plate as a size reference;

[0030] Step 3, obtaining an image including the bite joint and the measuring plate;

[0031] Step 4: Import the image into the image recognition system;

[0032] Step 5: Obtain all bite size information.

[0033] In the traditional method of measuring the bite of giant panda feces, it is necessary to bring the collected feces samples back to the residence / laboratory, as well as the tools for collecting and storing samples. People need to measure and record in person, and use vernier calipers, tables or computers to record data. It takes a long time, the work intensity is significantly greater, and there is a risk of measurement error. In this application, based on the photos of the bite taken, the scale 2 on the measuring plate is used as a reference for the size of the collected bite. The measurement function of the image recognition system is used to automatically obtain the length of each bite, and the length table is derived. The time required for measuring each picture is only 2-3 minutes to complete, and one person can measure the bite values ​​of multiple feces in batches at one time. The entire process of obtaining size data is fast and accurate, reducing manpower and physical energy consumption. This application can avoid errors caused by fatigue, interference, etc. during human measurement and recording, reduce labor intensity, and ensure the accuracy of bite data.

[0034] According to a further optimized solution, the measuring plate in step 1 is in a folded state before being prepared for use, and the measuring plate is in a flat state when in use.

[0035] When collecting giant panda feces outdoors, the measuring plate is set to a foldable state for easy carrying.

[0036] To further optimize the plan, in step 2, the collected giant panda feces are broken up and the separated bite segments are placed on the measuring plate.

[0037] After collecting the giant panda feces, break it up, and then spread the scattered, separated bite segments on the unfolded measuring plate, keeping gaps between adjacent bite segments to prevent them from sticking together.

[0038] In a further optimized solution, the scale 2 is set at the edge of the measuring plate, and the bite joint in the separated state is placed on one side of the scale 2. The scale line on the measuring plate is set to black.

[0039] The main purpose of setting scale 2 is to compare the bite section with scale 2 during the image acquisition process, so as to use scale 2 on the measuring plate as a reference for the size of the bite section of the collected giant panda feces; because the bite section will be kept on site after the bite section image is collected outdoors and will not be brought back to the laboratory or station, the bite section should be placed so as to avoid blocking scale 2 to prevent affecting the accuracy of information acquisition and improve work efficiency.

[0040] A further optimized solution further includes a fold line 3, and the measuring plate is separated into a plurality of PVC scale plates 1 by a plurality of fold lines 3. The PVC scale plate 1 is a white plate, and is matched with a black scale 2, which is more obvious when referring to the size.

[0041] The measuring plate can be the size of A4 paper, and a group of fold lines 3 is set, that is, the measuring plate is folded once; through the fold line 3, the measuring plate can be folded in half, reducing the storage space, and is convenient for outdoor carrying. The overall strength is high, wear-resistant, and not easy to deform; at the same time, the thickness at the fold line 3 is smaller than that of the PVC scale plate 1, which is convenient for folding in half.

[0042] The solution was further optimized and the thickness of the measured plate was 0.1mm-1mm.

[0043] The measuring plate needs to be of a certain thickness to ensure a certain strength, while being light and easy to carry. On the one hand, it can accommodate more bite nodes, and on the other hand, it is strong and durable.

[0044] To further optimize the solution, scale 2 is set to 1cm-5cm.

[0045] Prioritize the 5cm scale 2 as a reference and set it on the measuring plate. While taking pictures, record the comparison between the bite joint and scale 2.

[0046] To further optimize the solution, in step three, the measuring plate on which the bite joint is placed is photographed by a photographing device to obtain an image.

[0047] To further optimize the solution, the shooting device is a mobile phone or a camera.

[0048] Use a portable photographic device such as a mobile phone or camera to record the bite status.

[0049] To further optimize the scheme, in step 2, at least 30 bite nodes were placed on the measuring plate.

[0050] It takes 30 minutes to measure 30 bite segments by traditional methods. It takes even longer to measure more bite segments. If a large number of fecal samples are measured, at least two people are required to complete the process, which is a long process. In this application, the bite segment size in each image can be obtained in just a few minutes, with higher size measurement accuracy and higher measurement efficiency.

[0051] To further optimize the solution, in step 4, the image recognition system uses the image recognition system in the open source software Image J.

[0052] Traditional method of measuring the number of segments in giant panda feces: After finding giant panda feces in the wild, collect the giant panda feces with plastic bags, sealable bags, etc., and then bring it back to the station or laboratory for measurement. When measuring, first break up and separate the feces, then randomly select a certain number of segments, use a vernier caliper to measure the length of each segment, and record it on the corresponding record form or computer form. Since the number of segments measured must meet the requirements of statistical analysis for data, but measurement and form filling take a certain amount of time, the minimum number of segments measured is currently more than 30, and two people are required to work synchronously at the same time. Generally, it takes at least 30 minutes to measure 30 segments at a time, and it takes about 40 minutes for one person to complete; if 50 segments are measured, it takes about 1 hour.

[0053] This traditional measurement method takes a long time and is labor-intensive during field surveys. First, it is necessary to collect fecal samples and bring them back. Each sample weighs 200-300 grams. If there are many samples, in addition to being heavy, a larger container is needed to hold them, which undoubtedly increases the labor intensity of field work. At the same time, measuring the length of the bite segment with a vernier caliper is time-consuming and labor-intensive. Currently, a dedicated person is arranged to measure and record, which increases the manpower and time cost of the work. The labor intensity of long-term measurement is also high, and errors may occur in measurement and recording over time.

[0054] Compared with the traditional method, firstly, the present invention can significantly reduce the labor intensity. In the field work of the present invention, only a PVC scale plate 1 with a standard scale 2 and a mobile phone / camera are needed to take pictures, and there is no need to collect fecal samples back to the station / laboratory, which greatly reduces the physical exertion of the staff; at the same time, except for the initial time of taking pictures, the fecal bites need to be broken up, separated and laid on the flat plate, which takes a little time, and the rest is realized by computer software, and the measured length value data table is directly generated, and there is no need for people to measure and record in person, which reduces manpower and physical energy consumption.

[0055] Secondly, compared with traditional methods, the present invention saves time and greatly improves measurement efficiency. Based on the bite-joint photos with scales taken by the present invention, the length of each bite-joint is automatically obtained through the measurement function of the computer software, and the length table is exported. The measurement time required for each picture is only 2-3 minutes to complete, and one person can measure the bite-joint values ​​of dozens of feces in batches at one time.

[0056] Then, compared with the traditional method, the present invention can greatly improve the amount of bite data and data accuracy. Based on the bite pictures collected by the present invention, the bite length data can be quickly obtained through open source software. The measured bite amount can be increased as needed, without quantity restrictions, 50, 70, 100 bites are all possible, which can improve the accuracy of the bite average value; at the same time, the measurement through software can avoid errors caused by fatigue, interference, etc. during human measurement and recording, ensuring the accuracy of bite data.
