A method for counting seeds of a wheatear portion per wheat

Abstract

The invention discloses a method for counting seeds of a wheatear portion per wheat. The method comprises the following steps: S1, collecting a front view of the wheatear portion by utilizing a CCD camera and performing pretreatment on the collected front view; S2, carrying out mathematical morphology analysis, wherein the mathematical morphology is a new method applied to the field of image processing and pattern recognition; S3, extracting wheatear portion characteristic parameters, wherein the characteristics of the wheatear portion are extracted so as to establish correlationship between correlated characteristic parameters of the wheatear portion and the number of the seeds; and S4, performing mathematic model testing, which is for testing the correlationships between area characteristics as well as long axis characteristics of the wheatear portion and the number of the seeds so as to ensure the practicality of the two models. Through the method, mathematic models between the wheatear portion image area characteristics as well as long axis length characteristics and the number of the seeds are established through extracting the wheatear portion image area characteristics as well as long axis length characteristics, so that the number of the seeds of the wheatear portion can be accurately, rapidly and objectively counted, and compared with the manual work, the method greatly helps to improve the efficiency of seed counting.

Description

technical field [0001] The invention relates to a method for counting the number of grains at the panicle of a single wheat plant by using digital image processing technology. Background technique [0002] The number of grains in the ear of wheat is the number of full grains in the ear when the wheat is mature. [0003] The final yield in the wheat production process is always the most concerned thing for agricultural producers. In fact, in order to facilitate the post-harvest processing and management of wheat, it is always an urgent need for producers and agricultural management departments to know the wheat yield as early as possible and estimate the yield. Therefore, the estimation of wheat field yield needs to accurately know the specific number of grains on the ear when the wheat grains are mature. When agronomic breeding and cultivation experts conduct laboratory planting tests, they also hope to quickly know the number of wheat spikes and accelerate wheat breeding. ...

Problems solved by technology

[0006] It can be seen that the number of grains on the ear of wheat is one of the important basic steps in the measurement of theoretical yield. At present, the number of grains on the ear of wheat is obtained by manual counting, so as to obtain the yield of wheat. This method is time-consuming and laborious. There are also certain errors in the counting process, and different production measurement technicians may obtain different results, which has a large impact of subjectivity and poor accuracy.
