The measurement of plant leaf area is of great importance in agriculture and forestry. Many scholars at home and abroad have conducted many studies to measure leaf area. The easiest way to measure the blades is to use a scanner, which basically cuts the blades and then uses a scanner to measure the area. This method has the highest accuracy, but because this method destroys the blades, it can only be used for crop growth and development surveys. Can not be used for control or other areas. With the development of technology, a common measurement used for leaf area measurement in modern agriculture is the direct determination of leaf area detectors.
Without damaging the blade area under field conditions, it is not possible to use specific lighting and specific background colors, so noise and interference are difficult to avoid. Therefore, under the complicated background and severe interference conditions, how to use a variety of filtering methods to filter out various interferences and noises, and use binocular stereo vision methods to realize damage-free measurement of blade area under field conditions is very important. This is also a great advantage for the development and use of leaf area detectors.
For the seedlings of plugs, the use of seedlings with fewer leaves and less overlapping features will be used to further explore non-contact non-invasive measurements of leaf area of ​​plug seedlings on the basis of existing work, so that this technology can be truly applied to the actual production. . The cultivation site has extremely complex background conditions. The light environment, interference factors, and the spatial three-dimensional structure of the blade will bring great difficulties to the measurement of the damage of the blade area. Through the above-mentioned work, the leaf area detector has realized a single blade. The damage-free blade area measurement has high accuracy.
At present, the instrument that needs more adaptation in the measurement that does not cause damage to the blade is the leaf area detector. Although the damage is reduced, some minor damages are still avoided. If the leaf area detector can realize the binocular three-dimensional measurement of the leaf area, real measurement of non-contact and non-damaging leaf area has extremely important significance in precision agricultural production. The accuracy of the instrument has a certain relationship with the user's operating habits and proficiency.
