Embodiment Construction

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0024] Such as figure 1 As shown, the embodiment of the present invention provides a method for estimating the number of tree leaves, including:

[0025] S1, obtain the capacity of each branch on the target tree;

[0026] S2, based on the capacity of each branch on the target tree and the preset branch capacity-branch number lookup table, determ...

Abstract

The embodiment of the present invention provides a method and system for estimating the number of tree leaves, which can directly determine the capacity of each branch on the target tree by visual inspection, and then determine the target tree through the preset branch capacity-branch number lookup table The number of branches contained in each branch on the target tree; based on the capacity of each branch on the target tree and the number of branches contained in it, determine the total number of branches corresponding to each capacity branch on the target tree, and according to the capacity of each branch on the target tree The total number of branches corresponding to each capacity branch and the average number of leaves on each branch on the target tree determine the number of leaves on the target tree. The entire estimation process does not need to cut down the target trees, and can be achieved without damage. It is not only efficient, but also more suitable for situations where destructive sampling is limited. It enriches dendrology and plant community carbon measurement methods .

Description

technical field [0001] Embodiments of the present invention relate to the technical field of determining plant biomass indicators, and more specifically, relate to a method and system for estimating the number of tree leaves. Background technique [0002] At present, in the determination of biomass and leaf area of ​​trees, it is usually necessary to cut down the trees, pick all the leaves and weigh them. This is a common method at home and abroad so far. wreak havoc. In protected forests, destructive sampling is generally strictly prohibited. [0003] Therefore, there is an urgent need to provide a method and system for estimating the number of tree leaves, so as to realize non-destructive estimation of the number of tree leaves, and then determine parameters such as tree biomass and leaf area. Contents of the invention [0004] In order to overcome the above problems or at least partially solve the above problems, embodiments of the present invention provide a method a...
