Embodiment Construction

[0033] One of the cores of the present invention is to provide a method for measuring the shape of fruit trees, so that the distribution parameters of fruit tree branches can be counted and sorted out to form a fruit tree growth parameter library, which provides a theory for realizing mechanized pruning of fruit tree branches, precise pesticide application and mechanical picking data support.

[0034] Another core of the present invention is to provide a fruit tree shape measuring device capable of realizing the above measuring method.

[0035] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] Please refer to figure 1 , figure 1 It is a flow chart of the method for measuring the shape of fruit trees disclosed in the embodiment of the present invention.

[0037] In the fruit tree...

Abstract

The invention relates to a measurement method of a tree shape of a fruit tree. The measurement method comprises the following steps: 1) establishing a plane rectangular coordinate system vertical to the ground, wherein in the rectangular coordinate system, a direction parallel to the ground is a horizontal direction and a direction vertical to the ground is a vertical direction; 2) selecting a plurality of first-grade measurement points from one first-grade branch connected with a fruit tree trunk and projecting to the coordinate system; 3) fitting a branch curve of the first-grade branch according to coordinates of the first-grade measurement points on the rectangular coordinate system; and 4) selecting the other first-grade branch and repeating steps 2) and 3) until the first-grade branch is measured so as to obtain the tree shape of the first-grade branch of the fruit tree. The tree shape of each fruit tree at a phenological period is measured and a fruit tree growth parameter database can be formed, so that theoretical data support is provided for mechanical pruning, accurate pesticide application and mechanical picking. The invention further relates to a measurement device of the tree shape of the fruit tree, which can realize the measurement method.

Description

technical field [0001] The invention relates to the technical field of fruit tree planting, in particular to a tree shape measurement method and a tree shape measurement device capable of measuring the extension amount and azimuth angle distribution characteristics of fruit tree branches. Background technique [0002] At present, the shaping and pruning of branches to control the tree shape of fruit trees is carried out by manual experience, so as to ensure the consistent fruit bearing capacity of fruit trees every year and achieve the effect of high yield of fruit trees year after year; orchard plant protection spraying is also based on the growth phenology of fruit trees and the occurrence of pests and diseases Carry out timely operations; fruit picking operations are carried out according to fruit maturity and storage conditions. [0003] With the rise of labor costs, the labor-intensive links such as fruit tree pruning and plant protection spraying are gradually replaced...
