Crop canopy light distribution animation synthesis method

Abstract

The invention discloses the technical field of crop photosynthesis, in particular to a crop canopy light distribution animation synthesis method. At first, data of crop canopy is collected and a crop canopy geometry model is set up; sky visible rate of surface elements of the crop canopy geometry model is calculated; then light intensity of the surface elements is calculate; and finally color of the surface elements of a crop canopy key frame at set time is calculated through the light intensity of the surface elements and animation effects of crop canopy light environment are further achieved. The crop canopy light distribution animation synthesis method can be directly used in animation generation, and accurately reflects changes of the crop canopy light environment, real-time animation effects of real-time changes of light distribution in the crop canopy changing with external light environment are achieved, and further study work of agriculture researchers to crops is provided with convenience.

Description

technical field [0001] The invention relates to the technical field of crop photosynthesis, in particular to a method for synthesizing animations of light distribution in crop canopies. Background technique [0002] The visual description of the light environment changes in the crop canopy in a large field provides a more intuitive way for agricultural researchers to understand, and the real-time synthesis of crop canopy light distribution animations provides useful technical support for the production of agricultural popular science animation works. [0003] The simulation of crop canopy light distribution is mainly divided into three parts: the simulation of direct sunlight, the simulation of scattered light in the sky, and the simulation of multiple reflection and scattering inside the canopy. From the visual effect of actual visualization and the analysis of relevant literature, multiple reflections and scattered radiation inside the canopy can be ignored. Therefore, it ...

AI Technical Summary

Problems solved by technology

[0006] At present, there is no animation synthesis simulation method specially conducted from the perspective of crop canopy light interception. The animation synthesis of crop canopy light distribution simulated from the perspective of computer animation is faced with complex structures in the canopy, a large number of bins, and low real-time animation synthesis. However, the animation simulation from the perspective of computer animation often only pursues visual effects, which often cannot reflect the accurate light environment changes in the canopy.
