Abstract
Description
Technical Field
[0001] This invention relates to the field of crop cultivation technology, and specifically to a method for creating 3D crop paintings. Background Technology
[0002] Crop painting is an agricultural art form that uses farmland as a canvas and creates patterns by planting crops of different colors. It ensures agricultural production while also creating a leisure agricultural landscape.
[0003] Existing crop painting techniques primarily employ traditional flat painting methods. Simple designs are created using simple methods such as drawing lines on wooden boards or cardboard, or using grids drawn in the field. Complex designs are pre-defined based on a flat design plan, with bamboo sticks inserted at each coordinate point in the field. These points are then connected by ropes, and the design lines are traced onto the plot. Different colored crops are planted according to the color blocks in the design plan. However, flat painting relies on a vertical viewing angle, which has limitations. When the viewing platform is not high enough, too close to the field edge, or the design area is too large, the image will be severely distorted when viewed in person. Large-scale flat paintings typically require extremely high viewing positions or drone aerial photography to be clearly seen. However, when viewed from a high position relative to the crops, a high degree of color difference is required. If the color difference is insufficient, the color blocks of the design will blend together, obscuring the image. Conversely, using only crops with significant color differences results in a lack of color richness in the flat crop painting. Many types of crops require ridges and drainage ditches during planting, resulting in wider spacing between plants. When viewed from a relatively vertical perspective, the soil color may be visible through these gaps, affecting the appearance of the pattern. If the drainage ditches are not narrow enough, the pattern may even become unformed. Therefore, this limits the types of crops suitable for creating painted designs. Furthermore, because flat crop painting is viewed from a relatively vertical angle, the crops must be vigorous to achieve a canopy-closing effect for the pattern to take shape. Strict control of pests, diseases, weeds, and weather disasters, as well as meticulous water and fertilizer management, are also necessary to prevent localized poor growth or discoloration that could affect the overall presentation of the pattern. This significantly increases the difficulty of planting and management. Additionally, the crop cannot be viewed until it has reached canopy-closing stage, thus limiting the duration of the viewing period for the crop landscape.
[0004] It is evident that current flat painting techniques suffer from drawbacks such as distorted viewing patterns, insufficient color richness, short viewing time, limited crop planting options, and difficulties in planting and management. Summary of the Invention
[0005] Therefore, the present invention provides a method for producing 3D crop paintings to solve the problems mentioned in the background art, such as unavoidable pattern distortion, insufficient color richness, limited crop planting, high difficulty in planting and management, and short viewing time when viewing the current flat painting technology on site.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A method for creating 3D crop paintings includes the following steps:
[0008] S1. From the perspective of the observation deck, take a picture with the field of view in front of the human eye as the boundary of the lens to determine the shape of the canvas.
[0009] S2. Using the canvas as the design scope, design a painted pattern from the perspective of the observation deck;
[0010] S3. Measure the data of the viewing location and the field, create a topographic map using CAD and import it into 3D software, and establish a 3D model of the field based on the coordinates and elevation, combined with the plant height of the crops.
[0011] S4. Using the material editor and camera projection function in the 3D software, map the pattern drawn in step S2 onto the 3D model established in step S3 from the viewpoint coordinates; switch to the top view and render the pattern mapped onto the 3D model of the field into a high-definition image to obtain a planar planting pattern.
[0012] S5. Set up a square planting area from the perspective of the observation deck, and obtain the planar planting map of the square area according to the methods of steps S3 and S4; mark the four points of the square on the planar planting map in the field at the planting site; stand on the observation deck, hold a square card, perpendicular to the ground, and check the restoration effect of the planar planting map. If the four corners of the square can overlap with the positions of the four points in the field, it means that the field model is reasonable. If they cannot overlap, the model should be adjusted according to the distortion position.
[0013] S6. After step S5 verifies that the planar planting pattern is restored to a good condition, import the high-definition planar planting pattern obtained in step S4 into CAD. In CAD, measure the actual size of the pattern lines and color blocks. Combined with the size of the crop, check whether the pattern details can be planted. Based on the test results, adjust the unplantable parts of the pattern in the effect picture from the viewing platform. Repeat steps S4 and S6 until all pattern details can be planted.
[0014] S7. In CAD, the final plan of planting is traced and redrawn, and coordinate points are scientifically selected;
[0015] S8. Based on the coordinate points obtained in step S7, conduct field layout, insert bamboo sticks into the designated coordinate points, and connect them with ropes to draw the pattern on the plot.
[0016] S9. Based on the planting plan, plant crops of different colors in the designated area.
[0017] In step S1, determining the canvas shape refers to determining the field shape.
[0018] In step S2, the painted pattern for designing the viewing platform's perspective is either a two-dimensional or three-dimensional drawing.
[0019] In step S3, measuring the viewing position includes measuring the height of the viewing platform and the viewing angle.
[0020] In step S3, the data measured for the field includes the field's topography, slope, boundary points, and the location and number of ditches and trees within the field.
[0021] In step S6, the size of the crop being combined is the maximum cross-sectional diameter of a conventional plant.
[0022] In step S7, the error in selecting the coordinate points must not exceed ±3.
[0023] In step S9, the crop colors corresponding to the color blocks are marked first, and the crops are transplanted carefully along the line. The crops should be densely planted along the line, and then transplanted over a large area inside the color blocks. The edges of the lines are aligned, the distance from the lines is consistent, and the tops are aligned.
[0024] In step S9, if the graphic consists of a large area and a small area, the plant density in the small area should be greater than the plant density in the large area, and the height of the plants planted in the small area should be greater than or equal to the height of the plants in the large area.
[0025] In step S9, the crops are planted in an alternating pattern with gaps between them.
[0026] The present invention has the following advantages:
[0027] This invention provides a method for creating 3D crop paintings. Using a viewing platform as the perspective, crop painting patterns are designed. A 3D model of the project is constructed based on the viewing location and field data. The painting patterns are then mapped onto the 3D model to obtain a planar planting pattern. The crop paintings are then planted in the field according to this planar planting pattern. This allows for a holistic design of the crop planting pattern from the perspective of the viewing point and visitors, ensuring that visitors can appreciate normal and complete patterns from the viewing platform. It also enhances the realism and three-dimensionality of the visual effect, solving the problem that traditional planar crop painting often only shows distorted patterns or even no patterns at all, providing a better viewing experience. Furthermore, compared to traditional planar crop painting, this method does not require extremely high viewing locations or the use of drones for aerial photography. This closer viewing allows for less color difference in the crop plants, enabling the use of a wider range of crop colors. This method allows visitors to view crop paintings from eye-level and overhead perspectives. The front row of crops obscures the gaps between the back rows, easily achieving a foliage-covered-the-ground (row-closing) effect. Even if some plants are damaged or stunted, the overall effect remains unaffected by the mutual foliage covering the soil, significantly reducing planting and management difficulties. Furthermore, from this perspective, crops only need a short growth period after planting to achieve the row-closing effect. The method of interspersing and arranging crops further accelerates the formation of the pattern, extending the viewing period. When planting crops requiring drainage ditches, a horizontal arrangement facing the viewing position is used, ensuring each row of crops obscures the ditches behind it. This makes these types of crops suitable for crop painting, breaking down limitations on crop type. Special planting methods, such as dense planting along lines and alignment with edges, ensure that the crop paintings are not missing or distorted within designated areas. Verification of the planar planting pattern's restoration effect and details further guarantees the final presentation of the crop paintings.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] A method for creating 3D crop paintings includes the following steps:
[0034] S1. Define the canvas shape by fixing the point and height:
[0035] From the observation deck, take photos with the field of view directly in front of you as the frame boundary to roughly determine the shape of the canvas (plot) so as to formulate the structure of the crop painting pattern, reduce the number of times the pattern structure needs to be adjusted later, improve efficiency and save the design cycle.
[0036] S2. Creating crop illustration patterns:
[0037] Design a painted pattern from the perspective of a viewing platform, using a canvas as the design scope. The painted pattern can be a two-dimensional or three-dimensional image.
[0038] S3. Create a 3D model of the field:
[0039] a. Measure the viewing location, including the height of the viewing platform and the viewing angle.
[0040] b. Measure the data of the field, including the topography, slope, boundary points, and the location and number of ditches and trees within the field.
[0041] c. Create a topographic map using CAD, then import it into 3D software. Based on the coordinates and elevation, and combined with the plant height of the crops, establish a 3D model of the field.
[0042] S4. Obtain a planar planting pattern:
[0043] a. Using the material editor and camera projection function in the 3D software, map the painted pattern drawn in step S2 onto the 3D model of the field established in step S3 from the coordinate perspective of the viewing platform.
[0044] b. Switch to the top view to render a high-resolution image of the pattern mapped onto the 3D model of the field, thus obtaining the planar planting pattern.
[0045] S5. Verify the accuracy of the reconstruction of the planting plan:
[0046] a. Define a square planting area from the perspective of the observation deck, and obtain a plan view of the square planting area according to steps S3 and S4.
[0047] b. Mark the four points of the square on the planting plan in the field.
[0048] c. Stand on the viewing platform and hold a square piece of cardstock perpendicular to the ground. If the four corners of the square can overlap with the positions of four points in the plot, it means that the three-dimensional model of the plot is reasonable. Plant according to the plan and the planting effect can be reproduced from the perspective of the viewing platform. If they cannot overlap, the model should be adjusted according to the distortion position. After adjusting the model, continue to check until the planting effect can be reproduced.
[0049] S6. Inspect the details of the planting pattern:
[0050] a. After verifying the good restoration effect of the planar planting pattern in step S5, import the high-definition planar planting pattern obtained in step S4 into CAD.
[0051] b. Measure the actual size of the pattern lines and color blocks in CAD, and combine it with the size of the crop (the size of the crop is the maximum cross-sectional diameter on a regular plant) to check whether the planting pattern details can be planted. If some parts of the pattern cannot be planted, adjust them in the effect picture from the viewing platform. Repeat steps S4 and S6 until all pattern details can be planted.
[0052] S7. Plot the image and obtain the coordinates:
[0053] a. In CAD, redraw the final plan of planting;
[0054] b. Select coordinate points scientifically, with an error not exceeding ±3, to allow for errors during construction and crop painting.
[0055] S8. Lofting:
[0056] Based on the coordinate points obtained in step S7, conduct field layout by inserting bamboo sticks into the designated coordinate points and connecting them with ropes to trace the pattern on the plot. For crops that require drainage ditches, drainage ditches should be laid horizontally facing the viewing platform and ridges should be created before performing the layout operation.
[0057] S9. Crop Planting:
[0058] Based on the planting plan, different colored crops are planted in designated areas, while ensuring that planting conforms to design specifications to improve land utilization and crop growth efficiency; among which:
[0059] a. First, mark the crop color corresponding to the color block, and transplant carefully along the line. The planting should be dense along the line to prevent missing crops. Then transplant a large area inside the color block. The planting inside can be sparser to leave room for the crops to grow and reduce the probability of disease. Align the edges of the line, keep the distance from the line consistent, and align the tops to avoid encroaching on the boundary.
[0060] b. If the pattern consists of a large area enclosing a small area, the plant density in the small area should be greater than that in the large area, and the height of the plants in the small area should be greater than or equal to the height of the plants in the large area, so as not to block the sunlight in the small area and cause the pattern in the small area to be missing.
[0061] c. When planting, crops should be arranged in a staggered manner with gaps between them. This will result in a denser plant and a richer, more vibrant color more quickly than if they were planted in a neat arrangement.
[0062] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
