According to the device for automatically measuring the soft rot spot area of the in-vitro plant, the soft rot spot area of the in-vitro plant can be automatically measured, the measurement precision is high, meanwhile, the device is not affected by the environment, and accurate measurement can be conducted in the complex environment. Meanwhile, the scab area can be measured, and scab classification can be automatically carried out at the same time.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a device for automatically measuring the area of ​​soft rot disease spots of isolated plants. Background technique [0002] At present, the soft rot disease caused by bacteria is often caused by the accompanying miscellaneous bacteria to decompose the protein glue to produce indole and produce stench; the soft rot disease caused by Rhizopus nigricans produces gray-black mold on the surface of the diseased tissue, which is the cyst of the bacteria. Stems and sporangia. The lesions spread upwards from the petiole in sheets, and eventually the leaf bulb rots from the outside to the inside; when it expands from the root, the leaf bulb rots from the inside to the outside, and it is milky yellow muddy, smelly, and eventually loses its commodity value. After the root and stem base are damaged, the tissues become brittle, and the leaf balls are easy to fall off, and they...

AI Technical Summary

Problems solved by technology

However, the commonly used measurement methods for area are the graph paper method, the measurement method based on digital image analysis, and the contact area measurement method based on image measurement technology. Although the graph paper method is cheap and fast, its shortcomings are also very obvious and cannot be measured. A relatively accurate area value must be in contact with the measured object, and the measurement error is relatively large; the measurement method based on digital image analysis can obtain very accurate results, but the measurement system needs to be debugged in advance, and the camera and the measurement plane have Strict parameter requirements, and once it is successfully built, it cannot be moved freely; in addition, the contact area measurement method based on image measurement technology can meet the measurement of target images in different environments, and the required equipment is cheap, but this method must be used It is necessary to make contact with the target to be measured, and the measurement work in some environments does not allow direct contact with the target to be measured

[0005] Through the above analysis, the existing problems and defects of the existing technology are: the existing measurement method has high requirements for the environment, and cannot be used for more complex environmental scenes; The measurement process is complicated
