Plant leaf inclination angle measuring method and device

Abstract

The invention provides a plant leaf inclination angle measuring method and device. The method comprises the steps of acquiring a plant point cloud image of a target plant; performing clustering segmentation on the plant point cloud image to obtain a plurality of leaf point cloud images; carrying out surface reconstruction on any blade point cloud image, determining the actual area of any blade point cloud image, carrying out plane projection on any blade point cloud image, and determining the projection area of any blade point cloud image; determining an inclination angle of any blade point cloud image based on the actual area and the projection area; and determining a plant leaf inclination angle of the target plant based on the inclination angles of the plurality of leaf point cloud images. According to the plant leaf inclination angle measuring method provided by the invention, the inclination angle of the single leaf is obtained by obtaining the plurality of leaf point cloud imagesand based on the actual area and the projection area of the leaf point cloud images, so that the plant leaf inclination angle is obtained, damage to the plant can be avoided, and the precision of measuring the plant leaf inclination angle can be improved; the efficiency of measuring the plant leaf inclination angle is improved.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a method and device for measuring the inclination angle of plant leaves. Background technique [0002] Leaf inclination is an important parameter to describe the structure of vegetation canopy, which determines the amount of radiation intercepted by vegetation canopy and affects the photosynthesis rate of the whole plant. In addition, leaf inclination can be used as an indicator of plant growth status, such as water status. Therefore, measuring the phenotypic parameter of leaf inclination is crucial for improving plant yield. [0003] At present, in the technology related to measuring the inclination angle of plant leaves, the on-site measurement of the inclination angle of plant leaves is mainly carried out by inclinometers, protractors and compass. Time-consuming and labor-intensive, the calculation efficiency is low. Contents of the invention [0004] The inventio...
