Grain counting method for spike of single rice based on digital image processing technology

Abstract

The invention discloses a grain counting method for a spike of a single rice based on digital image processing technology. The method comprises the steps that S1) the correlation between a characteristics parameter and the grain number of the spike of the rice is established, a first branch of the spike is straightened, a spike image is obtained via a scanner, and the spike image is preprocessed; S2) mathematic morphological processing is carried out on the preprocessed spike image to remove part which is low in structural element, and a hole filling operation is carried out to remove all non-target objects; S3) characteristic parameters of the area and the total first-branch length of the grain part of the spike image are extracted; S4) mathematic models between the characteristic parameters and the grain number are established; and S5) the mathematic model between the characteristic parameters and the grain number are verified. The grain counting method based on digital image processing technology can be used to count grains of the spike accurately, rapidly and objectively, and the grain counting efficiency of the spike is improved.

Description

technical field [0001] The invention relates to a method for counting the number of grains at the panicle of a single rice plant by using digital image processing technology. Background technique [0002] The number of grains on the panicle of rice is the number of all grains on the panicle when the rice is mature. [0003] The final yield in the rice production process is always the most concerned thing for agricultural producers. In order to facilitate rice production and post-production processing management, early estimation of rice field yield has become an urgent need for producers and agricultural management departments. However, the estimation of rice field yield needs to obtain the number of mature rice spikes accurately. At the same time, in order to speed up rice breeding and cultivation management, agronomic breeding and cultivation experts also hope to quickly obtain the number of rice panicle grains when conducting laboratory planting tests. On the basis of ...

AI Technical Summary

Problems solved by technology

[0006] It can be seen that the number of grains on the panicle of rice is one of the important parameters for measuring the theoretical yield, but at present, the number of grains on the panicle of rice is obtained by manual counting. Different production measurement technicians may obtain different results, which are greatly affected by subjectivity, and have shortcomings such as poor accuracy and repeatability
