A kind of painting method of rice field 3D color painting

Abstract

The invention discloses a painting method of 3D color painting of a rice field, belongs to the field of agricultural plant cultivation, and aims at providing a painting method of 3D color painting ofa rice field which can make color painting of the rice field according to the position of a viewing platform, thereby having a more lively 3D ornamental effect. The painting method is characterized bycomprising the steps of S1, making and vectorization of a color painting picture; S2, establishment of a digital elevation model; S3, definition of a coordinate of the color painting picture, whereinone point in the vectorized color painting picture is taken as an original point, a coordinate system of the whole color painting picture is defined, and plane coordinates of all points relative to the coordinate system are determined; S4, positioning of a coordinate of the planting rice field, wherein perspective projection transformation is utilized, the plane coordinates are converted into thedigital elevation model of the planting rice field, a new object point projection coordinate is formed, a surveying and mapping technology is utilized to loft the object point coordinate into the planting rice field, and filed planting coordinates are formed; S5, rice field making. The painting method of 3D color painting of the rice field is applied to making of color painting of the rice field.

Description

technical field [0001] The invention relates to the field of agricultural plant planting, in particular to a painting method for 3D color painting of paddy fields. Background technique [0002] Paddy field painting, also known as paddy field painting, is mainly to plant green and colored leaf rice in paddy fields. When planting, first use a traditional liner in the farmland to determine the coordinates according to the pattern, and then draw the outline of the pattern or font with a line, and finally plant different colors. Variety of rice seedlings, as the rice grows, will present pre-planned graphics or text. Rice field paintings are generally used for viewing, and a viewing platform is set up around the landscape, so that tourists can clearly see the rice field graphics. [0003] The Chinese patent with the publication number CN108184579A discloses a simple production method of rice field painting. The steps include: (1) making colored drawings; (2) making wooden frames:...

AI Technical Summary

Problems solved by technology

However, tourists usually watch on the viewing platform. The above-mentioned method cannot make rice field paintings according to the position of the viewing platform, which is out of the perspective of tourists, and finally makes the 3D viewing effect of rice field paintings not ideal.
