Device and method for detecting comprehensive quality of crop seeds

Abstract

The invention discloses a device and method for detecting comprehensive quality of crop seeds. The detecting device comprises a charger (1), a conveyor belt (2), a motor (3), an imaging spectrometer (4), light sources (5), a processing unit (6) and a discharger (7), wherein the charger (1) is positioned right above one end of the conveyor belt (2); the imaging spectrometer (4) is positioned rightabove the middle of the conveyor belt (2) and used for acquiring a high spectrum data cube of the seeds to be detected; the motor (3) is used for driving the conveyor belt (2) to convey the seeds; the imaging spectrometer (4) is connected with the processing unit (6); and the two halogen tungsten lamp light sources (5) are positioned on two sides of the imaging spectrometer (4). The device and the method can be used for quickly and nondestructively detecting the comprehensive quality of single or multiple seeds.

Description

Technical field [0001] The invention relates to the technical field of crop seed detection, in particular to a device and method for comprehensive quality detection of crop seeds. Background technique [0002] The appearance quality and composition of crop seeds are important parameters of their comprehensive quality. The detection of the comprehensive quality of crop seeds is of great significance for grain quality classification, selection and breeding, and food processing. Currently, the online detection methods used for crop seeds include machine vision-based detection methods and near-infrared spectroscopy detection methods. The machine vision-based inspection machine mainly collects the image of the seed through an industrial camera, and then obtains the appearance characteristic parameters of the seed through an image processing algorithm, such as grain length, grain width, mechanical damage, disease, etc., so as to realize the detection of the appearance quality of the se...
