Embodiment 1

[0021] A method for measuring the number of effective grains of crops, the method steps are as follows:

[0022] Step 1: If figure 1 As shown, the equipment used includes a test bench 1, a metal bracket 2, a digital camera 3, an electronic scale 4, a computer 5, a black and white color guide 6 and a black and white grid calibration board, the digital camera is connected to the computer, and the metal bracket Install it on a horizontal test bench, then fix the digital camera on the metal bracket, adjust the position of the digital camera so that the lens is parallel to the test bench, and make the photographing area directly below the digital camera lens; use the white balance capture function of the digital camera to measure The white color guide is used as the standard white point comparison parameter of the camera, so as to realize the white balance processing of the camera; put the electronic scale with a measurement accuracy of 0.01g on the horizontal test bench, and adjus...

Abstract

The invention discloses a crop effective grain number measuring method. According to the crop effective grain number measuring method, the grain distribution images and accurate grain weighing data of crops in different varieties are obtained through photographing and weighing respectively; the number of the grains of the crops is extracted preliminarily through independently-developed data processing software and based on a mathematical morphology principle and a digital image processing technology; and the number of the grains is corrected by using the weighing data of the grains, so that imperfect grains are eliminated, and therefore, the extraction accuracy of the number of effective grains can be improved. With the method of the invention adopted, image preprocessing, and grain number accurate and quick identification and batch extraction can be carried out on photos with different grain conditions, and crop grain extraction accuracy can be ensured, and extraction speed can be greatly improved.

Description

technical field [0001] The invention relates to a method for measuring the number of effective grains of crops. Background technique [0002] With the rapid development of agricultural technology in our country and the great progress of research work in agricultural related disciplines, the output of different types of crops has been significantly improved, and the living standards of urban and rural residents have also been significantly improved, which makes people's demand for food The pursuit has gradually shifted from the pure quantity demand in the past to the quality requirement. Therefore, crop products with good taste, full grain, large and uniform grain shape, bright and lustrous color are more and more popular in the market, which makes the cultivation of new varieties of crops that focus on taste and yield more and more attention. In addition, with the increase of my country's rice, corn, soybean and other crop exports, in the international food import and expor...
