Technical Field

[0001] The invention relates to the field of agricultural science research, and in particular to a soybean hilum phenotypic image data collection tray and a collection method thereof. Background Art

[0002] The hilum of soybean refers to the scar left after the seed falls off the seed stalk or placenta, and its shape can be round, oval, or ovoid. The hilum is the only channel for the plant to transport nutrients to the seed during seed formation.

[0003] The color, shape, length, width, convexity and location of the soybean hilum vary depending on the plant species and can serve as an important basis for identifying seeds.

[0004] In order to realize artificial intelligence breeding, it is necessary to collect phenotypic data of a large number of seeds during the seed testing process, including the collection of hilum data. At present, the above-mentioned hilum data collection process is completely completed manually, and the hilum of a single seed is photographed from multiple angles manually, and the image of the seed is collected artificially to obtain its hilum image, which is then processed by computer to identify the phenotypic data of the hilum.

[0005] However, the above method has the following disadvantages:

[0006] (1) Manual image acquisition of a single seed hilum is labor-intensive and not suitable for batch acquisition of phenotypic data of the hilum;

[0007] (2) For the collection of a large number of seed images, the overall processing flow is inefficient, time-consuming, and image collection efficiency is low;

[0008] (3) The specifications of the plant images taken are different, such as size, position, etc. Summary of the invention

[0009] The problem to be solved by the present invention is to make up for the defects of the above-mentioned prior art and provide a sub-plate and a collection method thereof that can collect soybean hilum phenotypic data in batches and prevent inaccurate collected data caused by rolling of soybean seeds.

[0012] Furthermore, the number of the placement slots is n×m, and the seed placement area is always rectangular.

[0013] Furthermore, the rectangular groove includes a wide portion, a long portion and a second high portion, the wide portion should be smaller than the width of the smallest seed of this collection batch, the long portion should be larger than the length of the largest seed of this collection batch, and the second high portion should not exceed half the height of the seeds of this collection batch.

[0014] Furthermore, the circular groove includes a first high portion, the diameter of the circular groove is 11.0 mm, the height of the first high portion is 5.0 mm, the length dimension of the wide portion of the rectangular groove is 6.3 mm, the length dimension of the long portion is 9.0 mm, and the height dimension of the second high portion is 3.5 mm.

[0015] Furthermore, the dial includes a verification area and an information placement area. A colorimetric card is placed in the verification area for color verification of the final image of the seeds placed on the seed placement area. The information placement area is used to place the seed coding information and other related texts of the current photographed batch.

[0016] Furthermore, the lateral sides and longitudinal sides of the seed placement area are provided with row and column numbers.

[0017] Furthermore, the base includes a hand-holding hole, and the hand-holding hole is recessed on four sides of the base.

[0018] Furthermore, the base includes a reinforcement plate, which is arranged at the bottom of the base to strengthen the strength of the base.

[0019] A method for collecting phenotypic data using the sub-plate capable of collecting soybean hilum phenotypic image data as described above comprises the following steps:

[0020] Step 1. Place the colorimetric card in the verification area of ​​the sub-real disk, and place the QR code in the information placement area;

[0021] Step 2. Place the seeds to be tested on the placement slot of the seed tray, and use tweezers to move the seeds so that the hilum of the seeds is placed upward;

[0022] Step 3. Place the sub-solid plate at a designated position, and place a camera and a light source above the sub-solid plate, use the camera to take a picture of the sub-solid plate and save the captured image;

[0023] Step 4. Take the next batch of seeds to be tested. If the soybean variety number remains unchanged, go to Step 2 and repeat the above steps. If the soybean variety number changes, go to Step 1 and repeat the above steps.

[0024] Step 5. Transfer the captured image files of multiple seeds to the designated cloud server;

[0025] Step 6.

[0045] The words in this specification are used to illustrate the embodiments of the present invention, but are not intended to limit the present invention. It should also be noted that, unless otherwise clearly specified and limited, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For those skilled in the art, the above-mentioned specific meanings in the present invention can be specifically understood.

[0046] The present invention provides a seed tray capable of collecting soybean hilum phenotypic image data, wherein a batch of seeds are placed in the seed tray with the hilum facing upward, and then the seeds are photographed to collect soybean phenotypic image data, including phenotypic data of the soybean hilum and kidney, and then computer vision (CV) processing is performed on the collected image, and a model is established through deep learning to extract features, so as to obtain soybean hilum phenotypic image data for big data analysis.

[0047] Example 1

[0048] Please refer to Figure 1 to Figure 4 The present invention provides a sub-plate capable of collecting soybean hilum phenotypic image data, including a sub-plate 1, which is square and includes a base 11 and a dial 12, which are fixedly connected. It should be noted that the present invention does not limit the connection method between the two. The base 11 and the dial 12 can be threaded or snap-fit, and any connection method that fixes the two can be used. Preferably, in this embodiment, the base 11 and the dial 12 are integrally connected.

[0049] The base 11 includes a reinforcement plate 111 and a hollow groove 112. There are several reinforcement plates 111, and they are all arranged at the bottom of the base 11, and the bottom of the base 11 is divided into a plurality of hollow grooves 112, so that when the dial 12 is fixedly connected to the base 11, the material inside the sub-solid plate 1 can be reduced, thereby reducing the weight of the sub-solid plate 1.

[0050] Specifically, the reinforcement plate 111 includes a transverse and longitudinal reinforcement plate 1111 and an X-shaped reinforcement plate 1112. The transverse and longitudinal reinforcement plates 1111 are arranged in the transverse and longitudinal directions of the bottom of the base 11, and the X-shaped reinforcement plate 1112 is arranged in an X shape at the bottom of the base 11. Both the transverse and longitudinal reinforcement plates 1111 and the X-shaped reinforcement plates 1112 can strengthen the strength of the base 11 and prevent the base 11 from stretching and deforming.

[0051] Preferably, the transverse and longitudinal reinforcement plates 1111 include reinforcement ribs 11111, which are arranged on the edges of the transverse and longitudinal reinforcement plates 1111 close to the base 11. The height of the reinforcement ribs 11111 is greater than the height of the transverse and longitudinal reinforcement plates 1111, and a stepped structure is formed between the reinforcement ribs 11111 and the transverse and longitudinal reinforcement plates 1111. The reinforcement ribs 11111 can further strengthen the strength of the base 11 and prevent the base 11 from stretching and deforming.

[0052] The base 11 further includes a hand-holding hole 113 , and a plurality of hand-holding holes 113 are provided, and the hand-holding holes 113 are recessedly arranged on the four sides of the base 11 , so as to facilitate taking out the sub-solid plate 1 .

[0053] The dial 12 includes a seed placement area 121 , a verification area 122 and an information placement area 123 .

[0054] The seed placement area 121 is used to place batches of seeds for photography.

[0055] A colorimetric card is placed in the verification area 122 for color verification of the final image of the seeds placed on the seed placement area 121. The fixed position of the verification area 121 facilitates improving the image processing speed and is one of the elements of image acquisition standardization.

[0056] The information placement area 123 is used to place the seed coding information and other related texts of the current shooting batch. Specifically, the information placement area 123 can be used to place a QR code or a seed coding label. Preferably, the information placement area 123 is used to place a QR code. The advantage of the QR code is that it can replace the traditional coded text without considering the placement position and the angle when shooting, which can improve the image processing speed. This setting is also one of the elements of image acquisition standardization.

[0057] The seed placement area 121 is rectangular and includes a plurality of placement grooves 1212 for placing seeds. The placement grooves 1212 are recessed toward the base 11 and are used to place batches of seeds. The seeds can fall directly into the placement grooves 1212 .

[0058] The number of placement slots 1212 is n×m, that is, the number in the horizontal direction and the number in the vertical direction can be the same or different, but the seed placement area 121 is always in a rectangular shape of n×m. Preferably, in this embodiment, considering the number of seeds on a soybean plant, two sizes of placement slots 1212 are provided, namely 12×12 and 12×8, that is, 144 and 96 respectively.

[0059] In this embodiment, within the shooting range, the distance between two adjacent placement grooves 1212 is 13.1 mm.

[0060] The placement groove 1212 in the present invention can be set to different sizes according to actual needs. When the seed particles to be photographed are large, the hole position of the placement groove 1212 can be enlarged, and when the seed particles to be photographed are small, the hole position of the placement groove 1212 can be reduced. In this embodiment, it is mainly used to photograph soybean seeds, so the hole diameter of the placement groove 1212 does not exceed 11.0 mm, and the placement groove 1212 is concave downward, so that the soybeans can fall directly into the placement groove 1212 and will not easily fall out.

[0061] The placement groove 1212 includes a circular groove 12121 and a rectangular groove 12122. The rectangular groove 12122 is arranged at the bottom of the circular groove 12121, and is used to clamp the lower half of the seed. The circular groove 12121 includes a first high portion 121211, and the rectangular groove 12122 includes a second high portion 121223. The height of the circular groove 12121 is greater than the height of the rectangular groove 12122, that is, the height of the first high portion 121211 is greater than the height of the second high portion 121223, which is used to prevent the seeds from falling out when the sub-plate 1 is moved. At the same time, the height of the circular groove 12121 cannot be higher than the height of the seeds, that is, the height of the first high portion 121211 cannot be higher than the height of the seeds, so as to avoid shadows when taking pictures of the seeds and affect the subsequent computer recognition processing.

[0062] The length, width and height of the rectangular groove 12122 can be flexibly adjusted according to the size of the seeds to be photographed. Specifically, the rectangular groove 12122 includes a wide portion 121221, a long portion 121222 and a second high portion 121223, wherein the wide portion 121221 should be slightly smaller than the width of the smallest seed of this collection batch, so that the seeds can be stuck in the rectangular groove 12122 to prevent the seeds from rolling, and the long portion 121222 should be larger than the length of the largest seed of this collection batch, so that the angle of the seeds can be adjusted with tweezers to keep the seeds placed with the hilum facing upwards, and the second high portion 121223 generally does not exceed half of the height of the seeds of this collection batch, so that the widest part of the seeds is exposed in the upper part of the rectangular groove, ensuring that a complete top-view image of the seeds can be collected, and various phenotypic data such as the length and width of the seeds can be extracted at the same time.

[0063] The seed tray 1 in this embodiment is suitable for photographing seeds of larger size, wherein the diameter of the circular groove 12121 is 11.0 mm, and the height of the first high part 121211 is 5.0 mm. The length dimension of the wide part 121221 of the rectangular groove 12122 is 6.3 mm, the length dimension of the long part 121222 is 9.0 mm, and the height dimension of the second high part 121223 is 3.5 mm.

[0064] The horizontal and vertical sides of the seed placement area 121 are provided with row and column labels 1211, which are equivalent to column coordinates and row coordinates. The coordinates mark each seed in the seed placement area 121 so that the corresponding seed can be found according to the coordinates in subsequent computer recognition.

[0065] Among them, the column coordinates of the row and column labeled 1211 are marked as 1, 2, 3, ..., and the row coordinates of the row and column labeled 1211 are marked as A, B, C, .... According to the size of the seed tray and the number of seeds of a soybean plant to be collected, in this embodiment, two sizes of placement slots 1212 are provided, namely, 12×12 and 12×8 seed trays.

[0066] The sub-plate 1 is made of non-reflective material. Preferably, in the present embodiment, the sub-plate 1 is made of white or black industrial nylon as raw material and is manufactured by 3D printing to avoid adverse effects such as reflection when photographing the seed placement area 121. At the same time, since the surface of industrial nylon is non-reflective and not easy to deform, the overall stability of the sub-plate 1 can be ensured.

[0067] Example 2

[0068] The structure of the seed plate 1 in this embodiment is roughly the same as that in Example 1, except that: the seed plate 1 in this embodiment is suitable for shooting medium-sized seeds, and the sizes of several placement slots 1212 are reduced, wherein the diameter of the circular slot 12121 is 10.04mm, the height of the first high part 121211 is 5.0mm, the length dimension of the wide part 121221 of the rectangular slot 12122 is 5.3mm, the length dimension of the long part 121222 is 8.0mm, and the height dimension of the second high part 121223 is 3.5mm.

[0069] Example 3

[0070] The structure of the seed tray 1 in this embodiment is roughly the same as that in Example 1, except that: the seed tray 1 in this embodiment is suitable for shooting smaller seeds, and the sizes of several placement slots 1212 are reduced, wherein the diameter of the circular slot 12121 is 8.5 mm, the height of the first high part 121211 is 3.5 mm, the length of the wide part 121221 of the rectangular slot 12122 is 4.0 mm, the length of the long part 121222 is 6.5 mm, and the height of the second high part 121223 is 2.5 mm.

[0071] A method for collecting phenotypic data using the soybean hilum phenotypic image data collected using the above-mentioned seed tray is described in detail below.

[0072] The following steps are involved:

[0073] Step 1. Place a colorimetric card in the verification area 122 of the sub-disk 1, and place a QR code in the information placement area 123.

[0074] Step 2. Place the seeds to be tested on the placement slot 1212 of the seed tray 1, and use tweezers to move the seeds so that the hilum of the seeds faces upward.

[0075] The seeds placed on the seed tray 1 are generally placed continuously so that there are no missing seeds in the middle. Preferably, the seeds should be full-colored and round as much as possible.

[0076] Step 3. Place the sub-plate 1 at a designated location, and place a camera and a light source above the sub-plate 1. Use the camera to take a picture of the sub-plate 1 and save the captured image.

[0077] Preferably, the camera device is a high-pixel camera device and is equipped with a shadowless light. A mobile phone can also be used for shooting. When shooting, the height of the mobile phone should be fixed and the lens should be directly above the symmetry center of the sub-solid disk.

[0078] Preferably, when photographing the sub-solid plate 1, the photographing should be performed in a light-proof room to ensure that the light source does not change during the entire photographing process; at the same time, the light source is a fixed light source, and it should be directly above or close to directly above the symmetry center of the sub-solid plate 1 to avoid obvious shadows on the sub-solid plate 1; in addition, the light source should be avoided from being blocked when photographing to prevent changes in brightness.

[0079] Step 4. Take the next batch of seeds to be tested. If the soybean variety number remains unchanged, go to Step 2 and repeat the above steps. If the soybean variety number changes, go to Step 1 and repeat the above steps.

[0080] It should be noted that when repeating the above steps, the relative positions of the sub-plate 1, the camera device and the light source should remain unchanged, so as to keep the color homogenization difference of each point in the captured image unchanged.

[0081] If the position of the light source changes, the following steps need to be performed. If the light source does not change during the entire shooting process, the following steps only need to be performed once:

[0082] Step 41. Place a pure white colorimetric card in front of the camera to completely cover the seeds on the fruiting plate 1, take a picture of the colorimetric card, and then remove the colorimetric card.

[0083] Preferably, the standard colorimetric card No. 255, 255, 255 can be used.

[0084] The purpose of step Step 41 is to initialize the color homogenization difference of the sub-plate 1, which can avoid the difference in seed surface color caused by the seed placement area 121 being too large, the seed position being scattered, and the different distances from the camera device, so as to facilitate the computer image processing algorithm to obtain accurate seed surface color and glossiness.

[0085] Step 5. Transfer the captured image files of multiple seeds to the designated cloud server.

[0086] Step 6. The cloud server calls the image processing program to process the image file in parallel, extracts the phenotypic characteristic data of the seeds, the colorimetric card information of the verification area 122, and the QR code type number of the information placement area 123, and stores them in the phenotypic database.

[0087] Step 7. If there are seeds to be planted, go to Step 1 and repeat the above steps. If not, the collection of soybean hilum phenotype image data is completed.

[0088] The specific implementation methods of the present invention are described in detail above. For those skilled in the art, without departing from the principles of the present invention, several modifications and improvements may be made to the present invention, such as modifying the dimensions of the circular grooves and the rectangular grooves according to the size of the seeds to be photographed, etc. These modifications and improvements also fall within the scope of protection of the claims of the present invention.
