Plant growth modeling method and system

Abstract

The invention provides a plant growth modeling method and system. The method is characterized by collecting plant point cloud data, calculating shape features of plants, and extracting plant primitives based on the shape features of the plants, designing plant growth rules and fitting plant individual models to obtain plant growth parameters. In comparison, conventional plant growth modeling which focuses on the modeling of plant growth mechanism is mainly based on botany knowledge and expert experience, and is an empirical, qualitative and group-type virtual plant growth simulation; this modeling method is targeted to the behavior of plant population, so that the growth process of a specific plant individual is hard to simulate; and the modeling method depend heavily on professional knowledge and personal experience of botany experts. The plant growth modeling method and system are based on real measurement data of the plants, and can realize real plant growth modeling.

Description

technical field [0001] The invention relates to plant classification technology, in particular to a plant growth modeling method and system. Background technique [0002] Plants not only provide food sources for humans, but also provide humans with fresh air and an elegant environment. Human daily life is closely related to plants. It is no exaggeration to say that "the full use of plants determines the quality of human life in the future." For a long time, agricultural and forestry production has relied more on experience and knowledge in traditional ways. Nowadays, with the development of modern high-tech, "digital agriculture and forestry", "fine agriculture and forestry", "precision agriculture and forestry" and other modern agricultural and forestry production methods that make full use of information technology have become an important development trend, and have won more and more attention and attention. In fact, in order to obtain the optimal output of plant growth...
