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 invention provides a method and system for estimating the number of tree leaves. The method comprises the steps of determining the capacity of each branch on a tree directly through visual measurement, and then determining the number of branch shafts contained by each branch on the target tree through a preset branch capacity-branch shaft number lookup table; determining thetotal branch shaft number corresponding to the branch of each capacity on the target tree based on the capacity of each branch on the target tree and the number of branch shafts contained by each branch, and determining the number of leaves on the target tree according to the total branch shaft number corresponding to the branch of each capacity on the target tree and the average number of leaveson each branch shaft of the target tree. The whole estimation process does not need to cut down the target tree and can be implemented without damage. The method is not only high in efficiency, but also suitable for the case of limited destructive sampling, and enriches the forest measurement and plant community carbon accounting method.

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...
