A method and system for synthesizing apparent texture of leaves of parallel venation plants

Abstract

The invention relates to a synthesizing method and system for representation texture of parallel venation plant leaves. According to the method, the leaves are divided into a plurality of basic structure units according to texture characteristics; an image of the representation texture of each basic structure unit is obtained according to representation parameters of the parallel venation plant leaves; the images of the representation texture of the basic structure units are arranged so that the representation texture structure of a parallel venation plant can be formed. Through the method and system, not only can the generated representation texture structure of the parallel venation plant meet characteristics of an actually representation structure of the leaves, but also representation texture with any resolution ratio can be generated in theory; by controlling the difference of representation parameters of the units in the same column, the venation of the constructed representation texture structure of the parallel venation plant can be clearer.

Description

technical field [0001] The invention relates to a method and system for synthesizing the apparent texture of leaves of parallel venation plants, and relates to the technical field of plant simulation. Background technique [0002] With the continuous integration of information science and agricultural science, virtual reality technology has been applied more and more in the field of agriculture and has shown good application prospects. Three-dimensional virtual simulation of plants is an important issue in the fields of botany and agronomy, involving mathematics, computer technology, computer graphics, botany, agronomy, physiological ecology and many other fields. The realistic effect of three-dimensional virtual simulation of plants mainly depends on two aspects: three-dimensional shape and apparent texture. At present, the methods and technologies for data acquisition and model reconstruction of three-dimensional plants have gradually matured, and great progress has been ...

Problems solved by technology

However, there is still a big gap in the simulation of the apparent texture of major organs such as leaves.

It is difficult to meet the needs of high-quality and high-realistic virtual simulation by using photos as textures in traditional methods, which has become one of the important factors restricting the realistic effect of plant virtual simulation.

[0003] One of the core problems faced by plant 3D virtual simulation is realistic rendering and rendering. Since plants are living organisms, their own attributes and characteristics are different from those of industrial products. Although their apparent texture conforms to certain rules, it still contains more Random features, which lead to complex apparent texture and material information of plant leaves. In traditional plant virtual modeling methods, a leaf surface image is usually collected as a texture map, and this method is affected by the shooting environment, lighting conditions, and shooting conditions. Due to the constraints of various factors such as angles, the generated texture will have noise caused by the light environment, and the style is single; at the same time, because the leaves of the plants are of different sizes and have many folds, it is very difficult to take high-quality and high-resolution images

The above problems make it difficult for traditional methods to obtain high-quality and high-realistic simulation effects
