Method and device for measuring weight of thousand of seeds

Abstract

The invention discloses a method for measuring the weight of one thousand of seeds. The method comprises the following steps of: 1) paving a plurality of seeds to be detected and collecting an image and the weight of the seeds; 2) converting the image into a gray level image and carrying out filtering treatment on the gray level image; 3) carrying out binarization treatment on the gray level image which is subjected to the filtering treatment to obtain a binarized image; 4) extracting the outlines of the seeds in the binarized image and dividing according to the outlines and communication regions; selecting a characteristic point of the outline in each communication region and matching characteristic point pairs and establishing dividing lines between the two characteristic point pairs, wherein the dividing lines are used for dividing each communication region into a plurality of sub-regions; 5) counting the quantity of the sub-regions of all the communication regions to obtain the quantity of the seeds; 6) calculating the weight of one thousand of seeds according to the grain quantity and the weight of the seeds. The invention further discloses a device for measuring the weight of one thousand of seeds. The device disclosed by the invention is simple in structure, convenient to operate and high in measurement precision.

Description

technical field [0001] The invention relates to the measurement of the thousand-grain weight of crop seeds such as grain and oil plants, in particular to a method and device for measuring the thousand-grain weight of the seeds. Background technique [0002] Thousand-grain weight is the weight of one thousand grains (or converted into one thousand grains). It is an indicator that reflects the size and fullness of seeds. Seed thousand-grain weight is an important indicator to measure seed quality and high-yield performance. It is also an important standard for the study of quantitative genetics. For a long time, the measurement of 1000-grain weight of grain and oilseeds has been done manually, which is labor-intensive and time-consuming, and the cumbersome and repetitive work can easily make people tired and cause errors, which is not only inefficient but also inaccurate. [0003] With the rapid development of image processing, computer vision and pattern recognition technolo...

AI Technical Summary

Problems solved by technology

The camera cannot be used for continuous sampling, and the measurement speed is slow

The working condition of the mechanical tiling structure needs to be improved, the sample volume collected at a time is small, and there is a phenomenon of overlap of grains, which affects the accuracy of the thousand-grain weight determination
