Embodiment

[0062] Embodiment: a kind of three-dimensional interactive fruit tree virtual pruning method;

[0063] Contains the following steps:

[0064] S1. Preprocessing the three-dimensional model of the fruit tree to be pruned;

[0065] Step S1 includes steps:

[0066] S11, number each branch in the three-dimensional model of the fruit tree, check and receive the mother branch of each branch according to the connection relationship between the branches in the three-dimensional model of the fruit tree, record the number of the mother branch, and store the branch number information and the mother branch number information saved in file A;

[0067] S12. Carry out preliminary type marking for the branches that do not find the mother branch after the processing in the step S11, and mark them as long branches, middle branches or short branches according to the length of the branches, and save the preliminary type marking of the branches in file A;

[0068] If the branch length ≥ Llb, the...

Abstract

The invention provides a three-dimensional interactive fruit tree virtual trimming method, which relates to the technical field of three-dimensional interaction. The method comprises the following steps of: S1, preprocessing a fruit tree three-dimensional model planned to be trimmed; S2, creating a trimming operation rule for the preprocessed fruit tree three-dimensional model; S3, building a bounding box for positions which can be trimmed according to the trimming operation rule; S4, trimming in real time according to the bounding box for the positions which can be trimmed; and S5, simulating a trimming effect according to a real-time trimming operation result. The invention further provides a system. Due to the adoption of the method and the system, the practical problems of inconvertibility, non-repeatability, longer time before seeing a trimming effect and the like during trimming of real fruit trees are solved, a user can practice operating with various fruit tree trimming techniques on a computer, the shape changes of trimmed fruit trees are directly and vividly presented immediately, and the fruit tree trimming techniques can be popularized, trained and introduced into science popularization education in an easy, convenient and practical way.

Description

technical field [0001] The invention relates to the field of three-dimensional interactive technology, in particular to a three-dimensional interactive fruit tree virtual pruning method and system. Background technique [0002] Studies have shown that the tree structure of fruit trees has an important impact on its yield and quality. How to improve the tree structure and then improve the yield and quality of fruit trees is an important topic in fruit tree production and scientific research. Pruning is the main technical means to obtain high-quality and efficient tree structure. Therefore, fruit tree pruning technology is the most important management measure in fruit tree production. The promotion and popularization of advanced and practical pruning technology is an important task for the promotion of fruit tree industry. However, most of the current fruit tree pruning technology training and promotion work still adopts the method of live demonstration on the spot. Due to th...
