Embodiment Construction

[0061] The method for extracting wheat ear morphological parameters proposed by the present invention is described in detail in conjunction with the accompanying drawings and examples as follows.

[0062] In order to quickly obtain the morphological parameters of wheat spikes, the present invention proposes a method for quickly extracting spike parameters based on front-view images and side-view images of wheat spikes. This method divides the ear body and awn of the wheat ear, and on this basis, parameters such as ear length, ear shape, average awn length, number of awns, number of spikelets, etc. are extracted, and the morphological parameters of the wheat ear are improved. gain efficiency.

[0063] Such as figure 1 As shown, according to an embodiment of the present invention, the wheat ear morphological parameter extraction method comprises the steps:

[0064] S1. Use the reference object method to collect the front view and side view of the ear of wheat, and preprocess t...

Abstract

The invention discloses a method for extracting wheatear morphological parameters, which comprises the following steps: S1, adopting a reference object method to collecting a front view and a side view of the wheatear, and carrying out pre-process on the collected front view; S2, segmenting the pre-processed front view to obtain an image of the reference object and an image of the wheatear and calculate the pixel length ratio; S3, segmenting wheatear body and wheat awn of the wheat in the image of the wheatear to obtain images of wheatear body and wheat awn; S4, aiming at the image of wheatear body, adopting principal component analysis to find the axile wire and the outline of the wheatear body, calculating the length of the wheatear, and determining the shape of the wheatear; and S5, aiming at the wheat awn image, adopting a template matching method to count the number of the wheat awn and calculating the average length of the wheat awn. The method of the invention improves the comprehensiveness of the parameters extracting of the wheatear and the acquiring efficiency, and improves the objectivity and veracity of the wheatear morphological parameters extracting.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for extracting morphological parameters of wheat spikes. Background technique [0002] The ear morphological parameters of wheat are important indicators for breeding and identification of new varieties. At present, the morphological characteristics of wheat spikes are mainly measured by manual visual inspection and manual measurement to measure the characteristic parameters of wheat spikes: ear shape, average awn length, number of awns, ear length, number of spikelets, spikelet density, etc. And most of them take the whole plant of wheat, wheat grains, wheat leaves, etc. as objects, and use the image acquisition module connected to the computer to collect images, and transmit the collection results to the computer through the data transmission cable. Save and process for analysis. The existing measurement methods of wheat ear morphological characteristic para...
