Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] Embodiments of the present invention are as follows, as figure 1 The following steps are shown:

[0042] S1. Synchronously collect the front and back images of the moving rice seeds with a black and white industrial camera, and save them to the corresponding data buffer area respectively. Data buffer A and data buffer B both have a size matching that of the camera and a frame of image data capacity with a color bit depth of 8 bits.

[0043] S2. Monitor the data buffer area to check whether the data buffer area A or B is full, and start two threads if any buffer area is full. Data buffer A is filled and one thread is used to process the rice seed front image, and data buffer B is filled to use another thread to process the rice seed back image.

[0044] S3. In the respective threads, image processing and glume feature extract...

Abstract

The invention discloses a double analysis method of online glume-gaping seed rice identification. A monochrome industrial camera collects front-side and back-side images of moving seed rice synchronously, an image processing algorithm is used to carry out image processing and glume-gaping feature extraction on the front-side and back-side images successively, detection identification is carried out via the features in the front-side and back-side images, analysis results of the front-side and back-side images are integrated to implement screening and rejecting, and a detection result of the glume-gaping seed rice is obtained. According to the invention, the images of the two sides of the seed rice are obtained synchronously, multiple threads are used to process the images and realize engineering, and the glume-gaping seed rice can be identified and processed in higher precision and efficiency.

Description

technical field [0001] The invention relates to the technical field of machine vision, in particular to a double-sided analysis method for online identification of split glume seeds. Background technique [0002] In hybrid rice seeds, there is often a glume defect in which the glumes are not completely closed, resulting in a decrease in the vigor and germination rate of the rice seeds. However, the existing winnowing treatment methods cannot be automatically sorted. The research on using machine vision technology to detect seed quality, including patents CN200710067204.7, CN201110122572.3, CN200410078033.4, CN200910148225.0, CN201010237646.3, etc., all adopt single-sided detection or asynchronous acquisition of double-sided images, while the posture of rice seeds It cannot be fixed, and the split glume may appear on different sides. The existing technology cannot realize simultaneous collection of double-sided images of the same rice species for online double-sided analysis ...
