Description

Technical Field

[0001] The present invention relates to the technical field of agricultural plant planting, and in particular to a method for 3D color painting of rice fields in combination with colored rice species. Background Art

[0002] Rice field paintings, also known as rice field paintings, primarily depict the planting of green and colorful rice leaves in paddy fields. Planting begins with a traditional marker, using the field marker to determine coordinates according to a pattern. Lines are then used to trace the outline of the pattern or lettering. Finally, different rice seedlings are planted. As the rice grows, the pre-planned pattern or lettering takes shape. Rice field paintings are typically intended for viewing, with viewing platforms installed around the landscape to provide visitors with a clear view of the rice field patterns.

[0003] The Chinese patent publication number CN108184579A discloses a simple method for making rice field paintings, which includes the following steps: (1) making the painting; (2) making wooden frames: nailing fir or other wood into square wooden frames according to the specifications of 1 meter × 1 meter. The number of wooden frames is the same as the number of square grids in the painting effect picture, and the four sides of the wooden frames are marked with scales every 25 cm; (3) field coordinate positioning: referring to the painting effect picture, the pattern is decomposed into several construction areas, and each area is positioned at the field origin and marked with wooden stakes. A coordinate system is drawn with the origin as the center, and then square wooden frames are placed from the origin to the four coordinate areas. Each wooden frame corresponds to each square grid on the painting effect picture. The wooden frames arranged in this way can outline the pattern outline of the painting effect picture; (4) making the rice field.

[0004] This simple rice field painting method uses a number of individual wooden frames to create the outline of the pattern based on an initial two-dimensional painting rendering, and then proceeds to rice planting. Because the wooden frames are placed based solely on the two-dimensional perspective of the painting rendering, and tourists typically view the rice fields from observation platforms at a certain height above the rice fields, this method loses sight of the tourists during planting. Furthermore, it is impossible to accurately predict the final state of the colored rice production and the final painting rendering during planting, resulting in a poor 3D viewing experience for the rice field painting. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a method for 3D painting of rice fields in combination with colored rice varieties.

[0006] The object of the present invention can be achieved by the following technical solution: A method for 3D painting of rice fields in combination with colored rice species, comprising the following steps: S1.

The painted pattern is then designed by painting. The position and angle of the virtual camera are adjusted to simulate the visual effects of different viewing points. The rendering function of MAYA software is used to preview the images of each viewing point, and the best viewing point for displaying the painted pattern is selected. The ratio relationship between the main color variety and the matching color variety of the painted pattern is displayed to form a color map in mu units; S4. Use CASS software to map the rice field planting area, obtain detailed mapping data of the rice field planting area, match the mapping data with the information in the variety application database, and use the calculation function of CASS software to obtain the planting specifications suitable for the current planting area; S5. Performing graphic vectorization processing on the painted pattern to convert the painted pattern into an editable vector graphic, defining a coordinate system for the entire painted pattern with a certain point in the vectorized painted pattern as an origin, and determining the plane coordinates of all points in the painted pattern relative to the coordinate system; S6. Using perspective projection transformation, project the plane coordinates into the three-dimensional scene model in S2 according to the height of the best viewing point, and form new object point projection coordinates. Using surveying and mapping technology, the object point projection coordinates are staked out into the rice field to form field planting coordinates. S7.

The model parameters are adjusted according to the data of the growth stage of colored rice in the variety application database to reflect the morphological changes of colored rice at different growth stages.

[0029] Furthermore, in step S3, a three-dimensional animation effect is added to the three-dimensional model to simulate the growth process of the colored rice throughout the growth period.

[0030] Furthermore, a rendering engine is used to render the three-dimensional model to enhance the realism and stereoscopic effect of the visual effect.

[0032] Furthermore, labels and chart elements can be added to the video or interactive application to display key information and data during the growth of colored rice.

[0033] In specific use, before planting, the growth and maturity states of colored rice are first displayed through three-dimensional simulation. Based on the location of the viewing point and the viewing angle of people at the viewing point, the painted pattern effects of rice during the growth and maturity stages are previewed, and then the rice fields are planted and designed as a whole, so that the 3D viewing effect of tourists is better. Compared with the traditional rice field painting method, the coordinates are determined through surveying and mapping technology during the rice field design process, which not only saves a lot of manpower and material resources, but also can ensure the planting accuracy of the projected pattern, so that the shape of the pattern is not easy to deviate, and the viewing effect is better.
