Embodiment 1

[0057] Embodiment one: the basic seedling fast counting method of wheat based on machine vision and graphic processing comprises the following steps,

[0058] (1) Acquisition of basic seedling images

[0059] The image collection time of the basic wheat seedlings should be at the 1st-3rd leaf stage of the wheat seedling stage. After the 3rd leaf stage of the wheat seedling stage, the leaves of the wheat seedlings on the picture overlap more seriously, which will affect the recognition accuracy. In this embodiment, four test fields are respectively selected, and these four test fields are respectively planted with Yumai 49, Xinong 509, Zhoumai 27, and Aikang 58, these four common wheat varieties in Henan area, and during the period of 1-3 leaves of wheat Perform image acquisition.

[0060] In order to enable the method of the present invention to be applied to agricultural production practice at low cost, the resolution of the camera of the image acquisition device is not less...

Abstract

A fast counting method of wheat basic seedlings based on machine vision and graphics processing is proposed to solve the technical problem of low counting efficiency of wheat basic seedlings, and includes the following steps of acquiring basic seedling images, enhancing image restoration and performing target count. In the target count, the image processed by the step S8 is counted by using the connected area comparison method to obtain the number of wheat basic seedlings, so that the blocking adhesion of the wheat seedlings can be read and recognized, and the number of wheat basic seedlings is equal to the number of wheat seedlings counted in each connected area. By using machine vision and graphics processing method, the counting efficiency is high, and the method is suitable for large-scale statistics of wheat planting or germination.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting information collection and processing, and in particular relates to a fast counting method for basic wheat seedlings based on machine vision and graphic processing. Background technique [0002] Wheat is one of the important food crops in my country, and wheat production is directly related to national food security and social stability. In wheat production, the investigation and counting of basic seedling conditions of wheat are the most basic agronomic traits to ensure high and stable yield of wheat, and it is also one of the important parameters for predicting wheat yield. The determination of the basic seedling number of traditional wheat mostly adopts the survey method, that is, at the wheat seedling stage, the number of seedlings in a certain area is obtained by manual counting, and converted into basic seedlings per mu. The following two methods are commonly used: [0003] Th...
