Method for measuring leaf area, leaf perimeter, leaf length and leaf width

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...

AI Technical Summary

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 to quickly obtain the leaf area, but the instrument is expensive; the scanning method uses Photoshop, R2V and other software to count pixels to measure the leaf area

The above methods can only obtain the leaf area generally, and it is difficult to obtain the circumference, leaf length and leaf width of the leaf at the same time, especially it is difficult to complete the measurement task of multiple leaves at one time
