[0002] In agricultural production, thinning and fruit thinning of fruit trees is a cultivation technique.

[0049] The technical solutions in the embodiments of this specification will be described clearly and completely below in conjunction with the drawings in the embodiments of this specification.

[0050] Throughout this specification, the claims, and the accompanying drawings, the terms "first," "second," "third," and the like are used to distinguish between different items, not to describe a particular order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may include other steps or elements inherent to the process, method, product, or apparatus.

[0051] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the functions and arrangements of the elements described without departing from the scope of this specification. Various examples may appropriately omit, replace, or add various processes or components. For example, the described methods may be performed in an order different from the order described, and various steps may be added, omitted, or combined. Furthermore, features described with respect to some examples may be combined in other examples.

[0052] In the field of fruit tree flower and fruit thinning, although there have been relatively complete system devices for guiding fruit tree pruning techniques, the existing technologies are limited to a single fruit tree species and have limitations. Most methods can only identify a single variety and are not suitable for guidance and simulation teaching.

[0053] In view of this, the embodiment of this specification establishes an online simulation system for thinning flowers and fruits of fruit trees based on the comparison of fruit tree leaves and fruits, which solves the problems of irreversible damage, non-repeatable operation, and long action cycle when performing flower and fruit thinning on real fruit trees. It allows users to use computer simulation teaching to intuitively and repeatedly practice the technical process of thinning flowers and fruits of various fruit trees, and intuitively and vividly display the morphology of fruit trees after thinning flowers and fruits.

[0054] See also Figure 1 , Figure 1 This is a schematic diagram of a fruit tree flower and fruit thinning simulation system provided in an embodiment of this specification.

[0055] like Figure 1 As shown, the fruit tree flower and fruit thinning simulation system may at least include the following steps:

[0056] Step 101: The model building module builds a three-dimensional model of the fruit tree.

[0057] In a possible implementation, the model establishing module obtains an image of the fruit tree through a camera, and performs analysis and preprocessing on the image, so as to establish the three-dimensional model of the fruit tree.

[0058] It should be noted that the model establishing module can also collect environmental graphics of the fruit tree and geographical information, weather, temperature, humidity, and soil of the environment where the fruit tree is located in real time.

[0059] In step 102, the instruction obtaining module obtains the flower and fruit thinning instructions of each branch based on the leaf quantity information, flower quantity information, and fruit quantity information of each branch in the three-dimensional model of the fruit tree.

[0060] The instruction obtaining module comprises an information obtaining unit, a calculation unit, and an instruction generating unit connected in sequence.

[0061] The instruction obtaining module further comprises a grading unit connected with the instruction generating unit.

[0062] The instruction obtaining module further comprises a proportion setting unit connected with the instruction generating unit.

[0063] The instruction obtaining module further comprises a threshold setting unit, a determination subunit, a judgment subunit, and an instruction generating subunit connected in sequence.

[0064] In a possible implementation, the information obtaining unit obtains the leaf quantity information, flower quantity information, and fruit quantity information of each branch in the three-dimensional model of the fruit tree. The calculation unit calculates the leaf-flower ratio and leaf-fruit ratio of each branch according to the leaf quantity information, flower quantity information, and fruit quantity information of each branch in the three-dimensional model of the fruit tree. The instruction generating unit generates the flower and fruit thinning instructions of each branch according to the leaf-flower ratio and leaf-fruit ratio of each branch. The grading unit sets the grades of each branch in the three-dimensional model of the fruit tree.

[0065] In an example, the grading unit takes the center of the crown of the fruit tree as the center, divides the crown of the fruit tree into four regions of an upper crown region, a lower crown region, an inner crown region, and an outer crown region, and grades the branches in the regions, and according to the affiliation relationship, edits and splits the branches into 1st-level branches, 2nd-level branches, 3rd-level branches, and 4th-level branches. The 2nd-level branches grow on the 1st-level branches, the 3rd-level branches grow on the 2nd-level branches, and the 4th-level branches grow on the 3rd-level branches. Then, the instruction obtaining module groups the branches of each level of the fruit tree. One 1st-level branch and the 2nd-level to 4th-level branches growing on the 1st-level branch are one 1st-level tree branch, the crown is composed of multiple 1st-level tree branches, one 2nd-level branch and the 3rd-level to 4th-level branches growing on the 2nd-level branch are one 2nd-level tree branch, and the 1st-level branch is composed of multiple 2nd-level tree branches. The grouping is performed in the same manner to obtain the leaf quantity information, flower quantity information, and fruit quantity information of each branch.

[0066] The instruction generation unit generates thinning and fruit thinning instructions for each branch according to the leaf-flower ratio, leaf-fruit ratio, and branch grade of each branch. The ratio setting unit sets a leaf-flower ratio reference value and a leaf-fruit ratio reference value for each branch grade. The instruction generation unit generates thinning and fruit thinning instructions for each branch according to the leaf-flower ratio, leaf-fruit ratio, and leaf-flower ratio reference value and leaf-fruit ratio reference value corresponding to the branch grade of each branch.

[0067] In an example, the ratio setting unit sets the leaf-flower ratio reference value and the leaf-fruit ratio reference value for each branch grade according to the fruit tree species and the like in the database. The leaf-flower ratio reference value and the leaf-fruit ratio reference value can be adjusted according to actual conditions. The instruction generation unit determines the leaf-flower ratio or the leaf-fruit ratio for each branch grade according to the three-dimensional model of the fruit tree. The instruction generation unit generates thinning and fruit thinning instructions for each branch according to the leaf-flower ratio, the leaf-fruit ratio, and the leaf-flower ratio reference value and the leaf-fruit ratio reference value corresponding to the branch grade of each branch. For example, when the leaf-flower ratio and the leaf-fruit ratio on the branch of the fruit tree are less than the leaf-flower ratio reference value and the leaf-fruit ratio reference value corresponding to the branch, the branch displays a different color, and an instruction is generated to preferentially remove the flowers or fruits on the branch.

[0068] The threshold setting unit sets a flower retention amount threshold value and a fruit retention amount threshold value for each branch according to the fruit tree species and the like in the database. The target quantity determination subunit determines a target flower retention amount and a target fruit retention amount for each branch according to the leaf-flower ratio, the leaf-fruit ratio, and the leaf-flower ratio reference value and the leaf-fruit ratio reference value corresponding to the branch grade of each branch. Then, the judgment subunit determines whether the target flower retention amount is less than the flower retention amount threshold value and whether the target fruit retention amount is less than the fruit retention amount threshold value. The instruction generation subunit generates thinning and fruit thinning instructions for each branch according to the target flower retention amount and the target fruit retention amount and the determination results of the judgment subunit.

[0069] In an example, the target flower retention amount = actual leaf number / leaf-flower ratio reference value, and the target fruit retention amount = actual leaf number / leaf-fruit ratio reference value. If the target fruit retention amount is greater than or equal to the fruit retention amount threshold value, fruit thinning is not performed. If the target fruit retention amount is less than the fruit retention amount threshold value, fruit thinning instructions are generated for each branch. If the target flower retention amount is greater than or equal to the flower retention amount threshold value, flower thinning is not performed. If the target flower retention amount is less than the flower retention amount threshold value, flower thinning instructions are generated for each branch.

[0070] Step 103: The thinning and fruit thinning module performs thinning and fruit thinning operations on the three-dimensional model of the fruit tree according to the thinning and fruit thinning instructions for each branch.

[0071] The instruction acquisition module in step 102 further includes a thinning and fruit thinning order setting unit.

[0072] In a possible implementation, the flower and fruit thinning sequence setting unit sets the flower and fruit thinning sequence of each branch according to the spatial positions of the branches. The flower and fruit thinning module performs the flower and fruit thinning operation on the fruit tree three-dimensional model according to the flower and fruit thinning instructions of each branch and the flower and fruit thinning sequence of each branch. The flower and fruit thinning module performs the flower and fruit thinning operation according to the judgment result of the flower and fruit thinning sequence judgment subunit.

[0073] In an example, the flower and fruit thinning sequence setting unit sets the flower and fruit thinning sequence of each branch according to the spatial positions of the branches. For example, the flower and fruit thinning sequence setting unit sequentially performs the setting from top to bottom and from inside to outside in the order of the upper layer area of the crown, the lower layer area of the crown, the inner layer area of the crown, and the outer layer of the crown.

[0074] Further, the flower and fruit thinning module judges the fruits and flowers in the fruit tree three-dimensional model and identifies the disabled, weak, and branch edge flowers and the disabled, deformed, and weak young fruits. Then, the flower and fruit thinning module performs the flower and fruit thinning operation on the fruit tree three-dimensional model on the basis of the set flower and fruit thinning sequence of each branch. If the flower and fruit thinning operation is not completed on the basis of the set flower and fruit thinning sequence of each branch, the flower and fruit thinning module performs the flower and fruit thinning operation according to the number of flowers and fruits on each branch that is less than a preset density threshold in the fruit tree three-dimensional model, and does not perform the flower and fruit thinning operation on the flowers and fruits that are greater than the preset density threshold.

[0075] For example, the flower and fruit thinning module thins the branches in the order of the first-level branches, the second-level branches, the third-level branches, and the fourth-level branches, according to the leaf-flower ratio and the leaf-fruit ratio of the branches that are less than a preset threshold. The flower and fruit thinning module selects the second-level branches on the first-level branches, the third-level branches on the second-level branches, the fourth-level branches on the third-level branches, according to the number of flowers and fruits that are less than a preset threshold, and thins the branches in the order of the threshold from low to high.

[0076] It should be noted that the flower and fruit thinning module can perform the flower and fruit thinning operation on the front-end device operation interface according to the flower and fruit thinning instructions of the fruit tree. The front-end interface can acquire the flower and fruit thinning operation instructions of the user in response to the input or selection operation of the user. For example, the input or selection operation can be that the user inputs the data parameters of the flower and fruit thinning on the front-end device and clicks the instruction button corresponding to the flower and fruit thinning on the front-end interface. Then, the front-end interface sends the flower and fruit thinning operation instructions of the user to the flower and fruit thinning module. Correspondingly, the flower and fruit thinning module receives the flower and fruit thinning operation instructions sent by the front-end interface and performs the flower and fruit thinning operation on the fruit tree three-dimensional model according to the instructions. Then, the flower and fruit thinning module sends the result of the flower and fruit thinning to the front-end interface for display.

[0077] It should be further explained that the established fruit tree three-dimensional model provided by the embodiments of the present specification can also be used to predict the yield of the fruit tree that has completed the simulated thinning operation based on a fruit tree yield prediction model.

[0078] In a possible implementation manner, the fruit tree historical yield and the fruit tree three-dimensional model parameters corresponding to the fruit tree historical yield are trained based on a preset algorithm to obtain a fruit tree prediction model. The fruit tree three-dimensional model that has completed the simulated thinning operation is subjected to yield prediction based on the fruit tree prediction model.

[0079] The historical yield of a fruit tree = actual fruit quantity * fruit weight, the fruit includes small fruit and medium fruit, the fruit weight is determined based on a fruit leaf-fruit ratio density threshold value, and the fruit leaf-fruit ratio density threshold value module can be used for the determination. For example, if the density threshold value is X and the weight is N, N is a variable. When X > N mg, it is small fruit, when N mg > X > N mg, it is medium fruit, and when N mg < X, it is large fruit.

[0080] As can be understood from the above embodiments, the embodiments establish a fruit tree three-dimensional model, determine the fruit tree thinning instructions according to the fruit tree three-dimensional model, and finally perform thinning on the fruit tree three-dimensional model according to the instructions. The method proposed in the embodiments solves the problem of irreversibility and non-repeatability of thinning on real fruit trees, enables users to perform simulation and practice of various thinning techniques on a computer, and intuitively and visually displays the growth changes of the fruit tree, thereby making it easier, more convenient and more practical to carry out training and popularization of fruit tree thinning techniques. Compared with the method proposed in the prior art, the method can accurately simulate the thinning of various types of fruit trees.

[0081] In this embodiment, the fruit tree historical yield and the fruit tree three-dimensional model parameters corresponding to the fruit tree historical yield are trained based on a preset algorithm to obtain a fruit tree yield prediction model, and the yield of the fruit tree that has completed the simulated thinning operation is predicted. The embodiment can predict the yield of the fruit tree after the simulation of thinning is completed, enabling users to intuitively and visually display the results of the fruit tree thinning, and further improves the fruit tree thinning technology.
