Problems solved by technology

The feature point matching method is to use methods such as curvature detection and corner point detection to detect the feature points of the adhesion parts, and perform feature point pairing to realize the segmentation of the grain. This method can generally achieve higher segmentation accuracy. However, for complex adhesions, it is easy to have wrong feature point pairing

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] as attached figure 1 to attach image 3 Shown, a kind of fast counting method of rice and wheat grains of the present invention comprises the following steps:

[0026] Step 1) Acquisition of grain images: Use digital cameras, mobile phones and other photographing devices to obtain images of rice and wheat grains vertically. According to the habit of taking pictures, the distance between the mobile phone and the grains can be 20-60 cm; the background is selected to maximize the difference with the grains For the purpose, it is convenient to improve the integrity of grain extraction.

[0027] Step 2) Grain Extraction: extracting the grain using color features;

[0028] The original size of the image is 4160×3120pix. In order to improve the running efficiency, the image is normalized to 800×600pix, and the grain edge is smoothe...

Abstract

The invention relates to a rapid counting method for rice-wheat grains. The method comprises the steps of acquiring a grain image: vertically acquiring the image of rice-wheat grains by utilizing photographing equipment; extracting grains: extracting grains based on color features; detecting the angular points: extracting angular points at the adhesion parts of grains based on the angular point detection algorithm; detecting closed regions: detecting the number of closed regions formed by adhered grains based on the closed region detection algorithm; calculating the number of grains according to the following formula: the number of grains=the number of angular points at the adhesion parts of grains/2-the number of closed rgions+1. The counting method disclosed by the invention is high in calculation efficiency. Meanwhile, the number counting accuracy of grains is not influenced by human factors.

Description

technical field [0001] The invention belongs to the field of counting rice and wheat grains, in particular to a method for rapidly counting rice and wheat grains. Background technique [0002] Grain weight is an important part of yield, and crop yield is largely determined by the number of grains per spike and thousand-grain weight. Therefore, 1000-grain weight has always been used as an important parameter to measure the quality of cultivation measures and breed selection, and it is an index with a high frequency of measurement in crop research. To measure 1000-grain weight, the first step is to count the kernels. The commonly used methods include manual counting, electronic counters and image analysis techniques. Manual counting is time-consuming and labor-intensive, and human eyes are prone to fatigue, which will inevitably cause errors and cannot ensure accuracy. The electronic counter uses the breakpoints formed by the grains to pass through the laser to count. The pr...
