Problems solved by technology

The grid method and copy weighing method are simple to operate, but time-consuming and laborious; the leaf length and leaf width estimation method needs to use other methods to obtain the leaf area of ​​a certain number of samples, and calculate the formula according to statistical analysis, in order to use the formula and measure the leaf length and leaf area. The leaf area meter method uses a special leaf area meter

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 , 2 Shown, a kind of measuring method of leaf area, girth, leaf length and leaf width, at first utilize the scanning module to tile the collected leaves on the scanner of the scanning module, save into JPG or PNG format; secondly, utilize ArcGIS software The model builder constructs the model, the constructed model includes the input and output module and the ISO clustering non-supervised classification module and the field operation module in order to form a tool with a friendly interface; again, use the generated tool to input the leaf image and output path, Generate the perimeter, area, leaf length and leaf width data of each leaf in the folder; the constructed model also includes a folder image processing module with an iterator, an edge preprocessing module, a raster vectorization module, and a maximum circumscri...

Abstract

The invention relates to a method for measuring the leaf area, the leaf perimeter, the leaf length and the leaf width. According to the method, firstly, an acquired leaf is scanned by a scanning module, and the scanned image of the leaf is saved in the picture format. Secondly, a model is constructed by the model builder of the ArcGIS software, and the constructed model is composed of an ISO clustering unsupervised classification module, a field operation module, and an input and output module. The ISO clustering unsupervised classification module, the field operation module and the input and output module form a friendly-interface tool. Thirdly, by means of the generated tool, a leaf image and an output path are inputted, and then the area, perimeter, length and width data of each leaf in a folder are generated. The method aims to provide a novel method for spatial analysis and graphics by means of the ArcGIS software. The tool is constructed by the model builder, and then accurate leaf parameters, including the leaf area, the leaf perimeter, the leaf length, the leaf width and the like, can be automatically acquired in batches.

Description

technical field [0001] The invention relates to a method for measuring leaf area, circumference, leaf length and leaf width, and belongs to the field of digital measurement. Background technique [0002] As the main organ of plants for respiration, photosynthesis and transpiration, leaf area, perimeter, leaf length and leaf width are important parameters in the diagnosis of plant growth status. Mastering the growth law of plant leaves is of great help in guiding production. It is of positive significance to formulate high-yield, high-quality, high-efficiency and high-efficiency cultivation technology measures. At present, the common leaf area measurement methods include grid method, copy weighing method, leaf length and leaf width estimation method, leaf area meter method, scanner method, AutoCAD and so on. The grid method and copy weighing method are simple to operate, but time-consuming and laborious; the leaf length and leaf width estimation method needs to use other met...
