Nondestructive Segmentation and Extraction of Stem and Leaf Phenotypes During Tomato Plant Growth
摘要
Abstract
Aiming at the current problem that it is difficult to extract the phenotypic parameters of tomato plants without any loss,the stem and leaf segmentation and phenotypic extraction method of tomato plants based on 3D reconstruction was proposed.Firstly,the multi-view image sequences of tomato plants were collected to construct a 3D model of the plant,and a combination of multiple filtering algorithms was used to complete the pre-processing.The skeleton of the pre-processed point cloud was extracted using the Laplace-based skeleton extraction algorithm,and the segmentation of the stem and leaves was completed based on the skeleton of the plant,and the segmentation of the single leaves was completed using the method based on the clustering of hyperbolomers.6 phenotypic parameters including the height of the plant,the thickness of the stem,the angle of the inclination of the leaf,the length of the leaf,the width of the leaf,and the area of the leaf were also extracted.The results showed that the average accuracy,average recall and average F1 score of stem and leaf segmentation were 0.88,0.80 and 0.84,respectively,and the segmentation indexes were better than the other 4 segmentation algorithms.The coefficients of determination between the calculated and measured values of plant height,stem thickness,leaf inclination,leaf length,leaf width and leaf area were 0.97,0.84,0.88,0.94,0.92 and 0.93,respectively,and the root mean square errors were 2.17 cm,0.346 cm,5.65°,3.18 cm,2.99 cm and 8.79 cm2.The measured values of the proposed method had a strong correlation with the calculated values,which provided technical support for high-throughput phenotypic parameter extraction in tomato plants.关键词
