Embodiment

[0031] The method for counting particles based on image segmentation technology of the present invention is realized by computer software, comprising the steps of:

[0032] (1) Acquire the picture: take a solid color background that is enough to accommodate all the rice grains to be detected (note that the color is obviously different from the rice grains to be detected). In this case, since there are few rice grains to be processed, a piece of A4 paper is sufficient. Spread it flat on the paper. Be careful not to let the rice grains overlap vertically during the spreading process. Before taking pictures, pay attention not to tilt the light so that the background brightness of the picture is basically uniform; in this way, you can use your mobile phone or camera to take pictures, obtain sample photos, and copy the photos The electronic document is loaded into the program to get as figure 1 The desired image shown;

[0033] (2) Homogenize the picture containing the rice grain ...

Abstract

The invention discloses an image segmentation technology based granule counting method. The method is used for processing a picture carrying a sample granule pattern and obtaining number of sample granules. The method comprises the following steps: carrying out homogenization process on pictures; calculating weights of R, G and B values of pixel points of a current picture; performing iterative clustering so as to divide pictures into a background class and a sample granule class; performing pixel conversion so as to convert an original picture into a black and white picture with only two kinds of pixel points, wherein white represents sample granules, and black represents the background; and counting granules, wherein breadth-first searching is performed on pixel points of the picture so as to obtain the number of all sample granules. According to the image segmentation technology, K average value gray image segmentation and clustering classification technologies are used to process the picture carrying the sample granule pattern, so as to obtain the number of sample granules. The method has advantages of fast counting speed, lower requirements on sample quality and so on.

Description

technical field [0001] The invention relates to an agricultural particle counting method, in particular to a particle counting method based on image segmentation technology. Background technique [0002] In the process of seed cultivation and other work, such tedious and boring work as counting seeds is often encountered. With the continuous improvement of science and technology, the particle counting instrument has effectively replaced the backward working method of manual counting. The promotion of the application of the counting instrument by the relevant units of China's domestic agricultural departments will enable Chinese agricultural scientific researchers to improve their research level and save a lot of time in the process of breeding and selection. [0003] The existing particle counting instruments are mainly divided into two categories: physical photoelectric particle counting instruments and intelligent particle counting instruments combining software and hardw...
