Rice leaf shape collection device and method for extracting rice leaf shape parameters

Abstract

The invention relates to a rice leaf shape collection device and a method for extracting rice leaf shape parameters. A rice leaf shape collection device, its main body includes a camera, a camera fixing device, a bracket bar, a leaf loading platform, a bracket vertical bar, a bracket regulator, a computer, a check paper, double-sided adhesive tape, and a black tape; the camera is fixed through the camera The device is fixed on the horizontal bar of the bracket; the leaf loading table is a black horizontal tabletop, and the black tape is pasted on the leaf loading table with double-sided adhesive tape, and the side with the glue is facing upward; the vertical bar of the bracket is fixed on the side of the leaf loading board. In the center, the distance between the camera and the table can be adjusted through the bracket adjuster; the camera is directly connected to the computer; the verification paper is a piece of white paper with black equidistant grid points. Using the device and method of the present invention to collect rice leaf shape images and extract rice leaf shape curves and leaf areas is convenient, fast and accurate, and provides hardware and methods for the extraction of rice leaf shape and parameters, and can be used for the simulation and optimization of rice plant shape The design provides the basic parameters.

Description

technical field [0001] The invention relates to a data acquisition and parameter extraction method for accurate quantitative description of rice plant shape, in particular to a rice leaf shape image acquisition device and a method for extracting leaf shape curve and leaf area based on image analysis. Background technique [0002] There have been two breakthroughs in my country's rice production. One is to change the high-stalked rice to short-stalked rice, and the other is to change the short-stalked rice to hybrid rice. improved. The plant type improvement process is divided into two stages. The first stage is dwarf breeding, and the second stage is ideal plant type breeding. The development direction of ideal plant type breeding is to give consideration to both form and function, and to combine ideal plant type with advantage utilization. [0003] Plant type in a broad sense refers to the combination form of comprehensive biological traits and its overall expression, which...

This method is relatively simple and fast, but it is obviously inaccurate to use a uniform conversion value regardless of leaf shape

A method based on image measurement, designed by Zhang Jinheng (Zhang Jinheng, Wan Yu, Liu Shusheng, Lu Yongliang, Han Chao. A new device for measuring leaf area index: China, 200920154375.8 [P]. 2010-02-24.) The new device for measuring the leaf area index is not convenient for the design of the leaf placement method. Due to the image deformation, the calculation of the leaf area will also have a large error. The extraction of the leaf area based on Photoshop requires human intervention, and the boundary curve of the leaf cannot be extracted.
