Embodiment Construction

[0040] Concrete steps of the present invention:

[0041] a) Undersized detection:

[0042] Some kernels are very small in size. This kind of corn kernel has no practical value. Therefore, it needs to be filtered out in advance.

[0043] In the present invention, adopt following method to carry out the detection of small-sized corn grain:

[0044] a1. Capture background image

[0045] Before the detection of corn kernels, the background image needs to be obtained in advance. The method of obtaining the background image is as follows:

[0046] a11) Use a video camera to continuously shoot images for a period of time against the background.

[0047] a12) Detect whether there is a moving target in the images of this period of time. If present, a reshoot is required.

[0048] a13) If the segment of images is still, calculate the mean value for all images to obtain the background image.

[0049] a2. The difference between the current image and the background image

Abstract

The invention relates to an automatic corn detection method comprising the following steps: a) undersize detection; b) detection of the overall color of corn kernels; c) detection of corn kernel damage; d) wormhole detection; e) mildew detection; and f) surface crack detection. The method greatly reduces the detection cost and improves the detection efficiency.

Description

technical field [0001] The invention relates to grain safety detection, relates to corn, in particular to an automatic detection method for corn. Background technique [0002] Corn is the main food crop of Chinese people. In the process of collecting and storing corn, it is very common for corn to have mold, cracks, and wormholes. These abnormal corns will affect human health and must be detected and filtered out. [0003] The conventional method of artificially inspecting corn kernel by kernel is too expensive and the detection efficiency is low. Contents of the invention [0004] The purpose of the invention is to provide an automatic detection method for corn, which greatly reduces the detection cost and improves the detection efficiency. [0005] In order to achieve the above object, the technical solution adopted in the present invention is: a kind of corn automatic detection method, comprises the steps: [0006] a) Too small size detection: capture the background...
