Embodiment Construction

[0034] The invention provides a rapid identification and identification method for corn varieties that realizes non-destructive, rapid and reliable seed varieties by using machine vision technology.

[0035] Taking five varieties of corn as an example to illustrate the identification method of seed varieties. The situation of corn is shown in Table 1.

[0036]

[0037] 1. Establishment of standard sample image database

[0038] Using the American Epson 2480 scanner, the images of five varieties of standard samples were collected. First put the corn seed 3 on the tray of the scanner 2, insert the tray into the collection box, put the scanner on the top of the collection box, drive the scanner to collect the image information of the corn seed, and use the corn variety identification system on the computer 1 to identify the corn Seed, read the original image information (such as figure 1shown), store the image information of each pixel in each corn. Refer to the test trait...

Abstract

The invention discloses a method for quickly identifying and distinguishing the variety of corn, which belongs to the technical field of the detection of agricultural products. The method identifies the variety of the corn by an image processing technology quickly. Seed image information is obtained by a scanner, corn seeds are identified by a corn variety identification system on a computer, original image information is read, the image information of each pixel in each corn is stored as a 24-bit bmp format file, and the variety of the corn is distinguished by a trained neural network classifier after image processing and feature extraction are completed. The variety distinguishing rate of the model to an unknown sample is greater than 90%, which shows that a condition that the variety of the corn seeds is distinguished by image feature information is feasible. The invention has the characteristics of high automatization degree and quick, simple and convenient operation.

Description

technical field [0001] The invention belongs to the technical field of agricultural product detection, in particular to a method for rapid identification and identification of corn varieties, in particular to a method for rapid identification of corn varieties by using image processing technology. Background technique [0002] Maize is an important grain and feed crop in my country, and hybrid maize occupies an important position in my country's grain production because of its large sowing area and high yield. However, on the one hand, due to the many, chaotic and miscellaneous seed management channels in our country, and the lack of a seed certification system, it is difficult to guarantee the authenticity of the varieties; on the other hand, there is a lack of accurate, reliable, simple and fast varieties detection methods. It often brings a lot of inconvenience to the seed management department, variety protection department, and the majority of seed producers, operators ...
