Problems solved by technology

[0003] At present, the measurement of wheat ear length mainly relies on manual use of rulers to manually locate the two endpoints (neck node and apex) of wheat ears for direct measurement, but the measurement process is time-consuming and laborious, with personal subjectivity, poor repeatability, and digitization The degree is low, and it is easy to produce large errors; while the manual visual counting of spikelets mainly relies on human eyes to observe and count, which not only requires a lot of work, is laborious, consumes physical strength, is inefficient, and has poor objectivity and accuracy. subjective influence

Embodiment Construction

[0048] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0049] Such as figure 1 As shown, the present invention is mainly divided into six modules for processing the images of ear length and spikelet number of multiple wheat plants.

[0050] The first module is the image acquisition module, the main content is the image acquisition method;

[0051] The second module is the image geometric correction module, which is mainly divided into grayscale, filter denoising, circle detection, perspective transformation and other methods;

[0052] The third module is the wheat segmentation module, which mainly uses the Otsu method OTSU to binarize the image after the color image is subjected to light compensation processing, and uses the image segmentation technology to separate a single ...

Abstract

The invention provides a method for measuring the ear length and the ear number of multiple wheat plants based on image processing, and belongs to the technical field of computer image processing. Themethod solves the problem that the number of spikelet is mainly observed and counted by human eyes in the existing manual visual inspection, and is characterized by comprising the following steps: S1, acquiring a wheat graph; s2, geometrically correcting the image; s3, carryng out single-plant wheat segmentation; s4, cutting out an effective area of the length of the wheat ears; s5, calculating the ear length; and S6, calculating the spikelet number of the wheat. The method has the advantages that the labor cost and the equipment cost are saved, the working efficiency is greatly improved, andthe like.

Description

technical field [0001] The invention belongs to the technical field of computer image processing, in particular to a method for measuring the ear length and spikelet number of multiple wheat plants based on image processing. Background technique [0002] Wheat spike length and spikelet number can quickly and directly reflect the yield of wheat. They are two important parameters in wheat spike morphology. They are also important indicators for breeding and new variety identification, and are of great concern to wheat breeding experts. Agronomic status. [0003] At present, the measurement of wheat ear length mainly depends on the method of directly measuring the two endpoints (neck node and apex) of wheat ears manually using a ruler, but the measurement process is time-consuming and laborious, with personal subjectivity and poor repeatability. The degree is low, and it is easy to produce large errors; while the manual visual counting of spikelets mainly relies on human eyes ...
