Abstract

The invention provides a method and a system for measuring oilseed rape laminae and the forms of sclerotium scabs synchronously. The method includes the following steps of: acquiring images of the oilseed rape laminae infected with sclerotiniose; segmenting the acquired image to acquire background gridding images, and calculating pixel counts occupied by unit gridding and pixel counts occupied by unit length; extracting the images of the oilseed rape laminae, and calculating the areas, lengths and widths of the oilseed rape laminae; extracting the images of the sclerotium scabs, and calculating the areas, lengths and widths of the sclerotium scabs; and calculating the proportion of the sclerotium scabs to the integral oilseed rape laminae. The system comprises a gridding background plate, a tectorial membrane, a support, a clamping unit and an image acquisition and processing unit. By the method and the system, the synchronous, quick, accurate and nondestructive measurement of the oilseed rape laminae and the forms of the sclerotium scabs can be realized.

Description

technical field

[0001] The invention relates to the field of agricultural technology, in particular to a method, a device and a system for synchronously measuring the morphology of rape leaves and sclerotia lesion spots. Background technique

[0002] Rapeseed is one of the four major oil crops in the world. Sclerotinia sclerotiorum is a worldwide major disease caused by Sclerotinia sclerotiorum. hazards. Therefore, it is very necessary to accurately evaluate the severity of Sclerotinia sclerotiorum disease for the control, identification of sources of resistance and disease-resistant breeding of Sclerotinia sclerotiorum. The commonly used method for measuring the severity of Sclerotinia sclerotiorum is to grade the severity of the disease according to the size or number of lesions on the diseased leaves. Therefore, objective and accurate measurement of rapeseed leaves and sclerotinia lesion morphology is one of the urgent problems to be solved by rapeseed breeding and test...
