[0041] Example 1

[0042] like Figure 1 As shown, the corn auxiliary estimation device includes: a base 1, a connecting component, a clamping and comparing component 3, a first supporting component 2 and a second supporting component 6;

[0043] The first supporting member 2 and the second supporting member 6 are arranged opposite to each other and are both fixedly connected to the base 1;

[0044] The clamping and comparing component 3 is connected to the base 1 through a connecting component;

[0045] The clamping comparison component 3 cooperates with the first supporting component to clamp the corn to be tested;

[0046] The clamping comparison component 3 is engraved with a measuring scale and a reference disk 4 .

[0047] Specifically:

[0048] In this embodiment, the device further comprises: an elastic connecting member 7;

[0049] One end of the elastic connection component 7 is fixedly connected to the clamping and comparing component 3, and the other end is fixedly connected to the second supporting component.

[0050] In this embodiment, the connecting components include: a first connecting component 5 and a second connecting component 8;

[0051] The first connecting member 5 and the second connecting member 8 are arranged opposite to each other and are both fixedly connected to the base 1;

[0052] One end of the clamping and comparing component 3 is slidably connected to the first connecting component 5 , and the other end is slidably connected to the second connecting component 8 .

[0053] In this embodiment, the first supporting component 2 and the clamping and comparing component 3 are both provided with arc structures;

[0054] Moreover, the arc structure of the first supporting component 2 is matched with the arc structure of the clamping and comparing component 3, and is used to clamp the corn to be tested.

[0055] Example 2

[0056] Based on Example 1, this example discloses the following contents:

[0057] like Figure 5 In this embodiment, the base 1, the clamping and comparing component 3, the first supporting component 2 and the second supporting component 6 are all retractable structures, which is convenient for people to carry.

[0058] In addition, an anti-counterfeiting QR code is provided on the reference disk 4;

[0059] In practical application, the method of estimating corn yield based on machine vision is used to estimate corn yield specifically:

[0060] The corn to be tested is placed on the base 1 of the device of Example 1, and the height of the corn to be tested is parallel to the measuring scale on the clamping comparison component 3;

[0061] like Figure 2 The clamping and comparing component 3 and the first supporting component 2 cooperate to clamp the corn to be tested and collect the height image of the corn to be tested;

[0062] like Figure 3 Obtaining the cross-sectional image of the corn to be tested: dividing the corn to be tested, and placing a portion of the corn to be tested having the cross-sectional image of the corn to be tested on the base 1; the arc structure of the first supporting component 2 and the arc structure of the clamping and comparing component 3 cooperate to fix the portion of the corn to be tested, and acquiring the cross-sectional image of the corn to be tested;

[0063] The cross-sectional image of the corn to be tested and the height image of the corn to be tested are input into the AI ​​corn yield estimation model that has been trained in advance. The model uses machine vision technology to obtain the number of kernels per ear from the cross-sectional image of the corn to be tested and the height image of the corn to be tested. The model uses the formula: the estimated yield of one acre of corn = the number of plants per acre × the empty stalk rate × the number of kernels per ear × the thousand-grain weight, and then estimates the yield of corn per acre. It should be noted that the number of plants per acre, the empty stalk rate, and the thousand-grain weight are obtained by conventional means. Among them, the model converts the cross-sectional dimensions of part of the corn to be tested through the reference disk 4 of known size, and the model obtains the number of corn kernels in the current cross-sectional image of the corn to be tested; the model obtains the corn height through the corn height image to be tested, combined with the number of corn kernels in the current cross-sectional area, and the model converts the number of columns of the corn to be tested, and obtains the total number of kernels of the ear of corn by calculation.

[0064] It should be noted that in actual application, the model is integrated into the mobile phone APP software, and the mobile phone's built-in camera is used to capture the cross-sectional image and height image of the corn to be tested, and then transmitted to the mobile phone APP software integrated with the model. In combination with other data such as the number of plants per mu, empty stalk rate, and thousand-grain weight, the software outputs the corn yield estimation results.

[0065] Example 3

[0066] like Figure 4 A system for estimating corn yield based on machine vision comprises: the corn auxiliary estimation device of embodiment 1;

[0067] The system also includes: an image acquisition module, a data processing module and a data input module;

[0068] The image acquisition module is connected in communication with the data processing module, and is used to transmit the collected corn cross-section image and corn height image to be measured to the data processing module for processing; the data input module is connected in communication with the data processing module, and is used to provide a data input channel.

[0069] In actual application, the image acquisition module uses a camera; the data processing module uses machine vision technology to process the cross-sectional image of the corn to be tested and the height image of the corn to be tested transmitted by the image acquisition module, and outputs the number of kernels in the corn to be tested.

[0070] The data input module transmits other data required for corn estimation to the data processing module; other data include but are not limited to: number of plants per mu, empty stalk rate, and thousand-grain weight. The data processing module estimates the yield of corn per mu according to the formula: estimated yield of corn per mu = number of plants per mu × empty stalk rate × number of ears × thousand-grain weight; if the corn yield of a region needs to be estimated in actual application, the yield of corn per mu is multiplied by the number of mu in the region.

[0071] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
