Crop seed counting method based on image processing

Abstract

The invention relates to the field of computer image processing technology, and particularly to a crop seed counting method. The method mainly comprises the steps of performing preprocessing on a seed image; performing graying, binaryzation and seed picture boundary information reinforcement according to a Canny method on the seed image; classifying communicating domains in the image by means of a morphological characteristic and an area characteristic, wherein a first kind is divided seeds, and a second kind is adhered seeds; performing cutting on the adhered seeds according a recessed point characteristic; and finally finding out the number and positions of the communicating domains of the seeds after separation. The crop seed counting method overcomes the defects such as low seed counting speed and low efficiency in traditional seed breeding. Furthermore image processing technology is successively applied on the seed breeding field. Through verification on five kinds of crop seeds, the identification rate is above 99%. The processing time on a common PC is lower than three seconds, and therefore high speed and high accuracy in seed counting are realized. Furthermore a powerful technical support is supplied for seed counting in seed breeding.

Description

technical field [0001] The invention relates to the technical field of computer image processing, in particular to a method for counting crop seeds. Background technique [0002] In order to carry out scientific research experiments such as seed quality inspection, yield measurement, and seed testing, counting seeds is an indispensable step, and the accuracy of counting seeds has a great impact on the experimental results. Breeding is a technique for cultivating new varieties of animals and plants by creating genetic variation and improving genetic characteristics. It is of great significance to the development of planting and animal husbandry, and counting is an important part of breeding. Domestically, the use of digital image technology for breeding started relatively late. In recent years, the importance of China's agricultural development has become more and more prominent. Among them, breeding technology is a very important part of agricultural development, which has a...

Problems solved by technology

[0004] The main purpose of the present invention is to provide a crop seed counting method based on image processing, which overcomes the problems of slow image segmentation and low accuracy, and overcomes the low efficiency, error-prone, large labor force and mechanical and electrical integration of traditional manual counting at the same time. There are problems such as large errors, complicated manufacturing, and expensive prices in the seeding equipment. The image processing technology is better applied to the field of breeding, achieving fast and accurate seed counting, and providing strong technical support for breeding counting.
