Fruit tree canopy illumination distribution calculation-based clipping evaluation method

Abstract

The present invention provides a fruit tree canopy illumination distribution calculation-based clipping evaluation method. The method comprises the following steps that: in each of any two years in N years before a current year for clipping evaluation, a sample tree and a tree under test are clipped in the same way in the spring, and sprout, thereafter, the box counting dimensions of the three-dimensional point cloud data of the canopy of the sample tree in cubic grids at different positions and the illumination intensity or relative illumination intensity of the sample tree in each grid during a canopy curtain stable phase are obtained, and a mathematical model is established; and the illumination intensity or relative illumination intensity distribution result of the canopy curtain stable phase of the tree under test in the current year for clipping evaluation is predicted through the mathematical model, and whether the fruit tree is clipped properly is evaluated. The method has the advantages of quickness, convenience, reasonable calculation method, high accuracy and suitability for automatic programming, and can greatly improve work efficiency and reduce the labor intensity of the workers.

Description

technical field [0001] The invention relates to a pruning evaluation method based on calculation of fruit tree canopy illumination and facilitating the result. Background technique [0002] Fruit tree shaping and pruning, as an important technology in the implementation of comprehensive management, is generally valued by the majority of fruit farmers and scientific and technological workers. To a large extent, it can reasonably adjust the relationship between fruit tree growth and fruiting, and affect the formation of yield and quality. It is the main technical means to obtain high-quality and efficient tree structure. Pruning can also provide convenient conditions for various field operations. [0003] Through scientific and reasonable pruning, the distribution, transportation, accumulation and digestion of nutrients and hormones can be re-adjusted, the relationship between fruit trees and the surrounding environment can be changed, the balance between various parts of frui...

AI Technical Summary

Problems solved by technology

[0005] In view of the lack of effective evaluation methods for fruit tree pruning and pruning in the prior art, the purpose of the present invention is to provide a pruning evaluation method based on the calculation of fruit tree canopy illumination to solve the evaluation problem of whether fruit trees are reasonably pruned
