Abstract

The invention discloses a plant leaf area measuring instrument. The plant leaf area measuring instrument comprises an image acquisition module, a data processing module, a data storage module and a display module, wherein the image acquisition module is connected with the data processing module and is used for measuring transverse leaf width, the data processing module is further connected with a FLASH memory and a liquid crystal display, the liquid crystal display is used for displaying the leaf information acquired by the image acquisition module in real time, and the FLASH memory is used for storing and saving the leaf information. The measuring instrument is advantaged in that offline operation can be realized, FPGA parallel processing capability is performed, high-speed image acquisition and processing can be realized through the image acquisition module and the data processing module, leaf area algorithm application programs are accomplished in a software mode, software and hardware cooperation design is realized, leaf area measurement on detached leaves is stable and reliable, other leaf parameters can be measured, and strong system flexibility is realized.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of digital agriculture, and in particular relates to a plant leaf area measuring instrument. [0003] 【Background technique】 [0004] Leaf area is a commonly used indicator in some crop cultivation and breeding practices. The total area of ​​leaves is also an evaluation index of crop yield and quality. The size of leaf area is an important research content for afforestation management, ideal plant type selection and afforestation density. Pest leaf eating area is also an important content in the study of pest damage loss and economic threshold. It can be seen that fast and accurate measurement of leaf area is very important. [0005] At present, the traditional leaf area measurement mainly includes grid method, weighing method, coefficient method, image processing method, leaf surface instrument measurement method, etc. These methods have their own advantages and disadvantages. For example, the gri...
