[0018] The utility model will be further described below with reference to the drawings.

[0019] The portable multi-platform compatible seed morphology measuring device is horizontally placed on a workbench and comprises a seed placing table 4 and a base 5, and four lower supports 3 are fixedly connected to the four corners of the upper surface of the base 5, and the lower supports 3 are kept perpendicular to the base 5.

[0020] The seed placing table 4 is horizontally placed on the upper surface of the base 5, and the seed placing table 4 comprises a middle plate 4-1 horizontally placed on the upper surface of the base 5 and a glass table 4-2 horizontally placed on the upper surface of the middle plate 4-1, wherein the glass table 4-2 is located in the space surrounded by the lower supports 3. An upper support 2 is fixedly installed at the upper end of the lower support 3.

[0021] The top of the upper support 2 is fixedly installed with a horizontally placed connecting assembly 6, and the connecting assembly 6 comprises a bonding plate 6-1 and a connecting shaft 6-2, the bonding plate 6-1 is fixedly installed on the top of the upper support 2, the connecting shaft 6-2 is installed on the bonding plate 6-1, and one end of the connecting shaft 6-2 extends into the bonding plate 6-1. A first opening part 6-1-1 is formed on the surface of the bonding plate 6-1 facing the upper support 2, and a second opening part 2-1 is formed on the surface of the upper support 2 facing the bonding plate 6-1. A camera (not shown) is installed on the connecting shaft 6-2 inside the bonding plate 6-1, and the lens of the camera faces downward, so that the lens of the camera can face the seed placing table 4 due to the existence of the first opening part 6-1-1 and the second opening part 2-1.

[0022] The camera is externally connected to a power adapter through a power line to ensure that the camera can be normally powered. The camera is connected to a computer or other image acquisition equipment through a data line to ensure that data transmission is normal. The image acquisition equipment is connected with an image processing equipment through a data line, the image processing equipment is connected with a data storage and transmission module through a data line, and the data storage and transmission module is connected to a user interface through a data line.

[0023] The image acquisition equipment is used for capturing high-definition images of the seed to be measured. The image processing equipment pre-processes and extracts the morphology parameters of the captured images. The data storage and transmission module stores the extracted morphology parameter data and transmits them to the user interface of the portable device through multiple communication modes.

[0024] To ensure the accuracy of the measurement, the camera needs to be aligned and calibrated. The specific steps are as follows:

[0025] Preliminary alignment: When installing the camera, make sure its lens is directly opposite the center of the seeding table 4. Use a level to check the horizontal state of the camera, and make sure its lens is parallel to the seeding table 4.

[0026] Fine-tune alignment: Turn on the image acquisition device connected to the camera and observe the image of the seeding table 4 taken by the camera. If the center of the seeding table 4 in the image does not coincide with the center of the camera's field of view, fine-tuning is needed. Use the connecting shaft 6-2 in the connecting assembly 6 to fine-tune the camera by gently rotating or moving it so that its lens is aligned with the center of the seeding table 4.

[0027] Precise alignment: In the image acquisition device, observe the image of the seeding table 4 taken by the camera to ensure that the image is clear and the center of the seeding table 4 completely coincides with the center of the camera's field of view. If there is still deviation in the center of the seeding table 4 in the image, repeat the fine-tuning steps until alignment is achieved. Ensure that the focal length and focus settings of the camera are correct to obtain a clear image.

[0028] Calibration verification: Place a standard object of known size (such as a standard ruler or calibration block) on the seeding table 4, take a picture and check if the size is consistent with the actual size. If there is a deviation in size, adjust the focal length or focus settings of the camera until the size of the image taken is consistent with the actual size.

[0029] The seed morphology parameter detection method based on the portable multi-platform compatible seed morphology measurement device provided by the present utility model has the following specific steps:

[0030] Step 1: Take a picture of the seed to be measured, and the image acquisition device obtains image data. The image processing device pre-processes the image data.

[0031] Step 2: Use edge detection and other image processing algorithms to extract the contour image of the seed.

[0032] Step 3: The image processing device performs morphological analysis on the contour image of the seed to obtain the specific values of the seed's morphological parameters, including length, width, perimeter, area, etc.

[0033] The image data is obtained by taking a picture of the seed to be measured using the portable multi-platform compatible seed morphology measurement device. This device has multi-platform compatibility and can run on different operating systems and devices, such as smartphones, tablets, laptops, etc., providing great convenience for seed morphology parameter measurement.

[0034] Step 4, the data storage and transmission module stores the extracted morphological parameter data and transmits it to the user interface of the portable device through various communication methods. The user performs statistical analysis on the morphological parameter data of the seeds, such as calculating the mean, standard deviation, maximum value, minimum value, etc. to obtain statistical results. The statistical results are used to indicate the change trend or distribution characteristics of the morphological parameters of the seeds under different conditions.

[0035] In step 1, the seeds to be tested are photographed to obtain image data, and the image data is preprocessed. The preprocessing specifically includes denoising, contrast enhancement, etc. to improve the accuracy of morphological analysis. These preprocessing steps can reduce noise and interference factors in the image, making the seed contour more clear and accurate.

[0036] In step 2, the image processing algorithm can use conventional processing methods in the art, which will not be described here.

[0037] In step 3, the contour image of the seed is subjected to morphological analysis to obtain the specific values of the morphological parameters of the seed. The specific steps are as follows:

[0038] 3.1. Based on the seed contour image, first determine the minimum circumscribed rectangle of the seed, which can completely contain the seed contour and has the smallest area.

[0039] 3.2. Calculate the length and width of the minimum circumscribed rectangle as the length and width of the seed.

[0040] 3.3. Based on the seed contour image, calculate the perimeter and area of the seed contour through common methods such as contour tracking algorithm in the prior art. These two parameters can reflect the shape and size characteristics of the seed, which are of great significance for seed quality evaluation, growth condition monitoring, etc.

[0041] Through the above steps, the seed morphological parameter detection system based on the portable multi-platform compatible seed morphological measurement device can obtain morphological parameter data such as length, width, perimeter and area of the seed, providing a basis for subsequent statistical analysis.

[0042] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the art, without departing from the principles of the present application, a number of improvements can be made, which should also be considered as the protection scope of the present application.
