Embodiment 1

[0060] Embodiment 1, a method for identifying green plants in field crop growth monitoring images.

[0061] The method provided by the present invention for identifying green plants in field crop growth monitoring images presupposes that the user has collected the field crop growth monitoring images by using a field camera. The field crop in this embodiment takes field corn as an example. The goal of this embodiment is to identify the green corn seedlings from the field corn growth monitoring image, so as to facilitate the subsequent realization of field corn growth judgment, so as to provide irrigation, fertilization, Agricultural production activities such as deworming provide a basis for decision-making; that is, the target image of green corn seedlings obtained in this embodiment provides a basis for subsequent field corn growth analysis.

Embodiment 2

[0095] Embodiment 2, a system for identifying green plants in field crop growth monitoring images.

[0096] Such as Figure 4 As shown, the system for identifying green plants in field crop growth monitoring images provided by this embodiment includes a background image element removal module 200 , a green factor matrix calculation module 300 and a green plant identification module 400 .

[0097] The background image element removal module 200 further includes a green plant distinguishing unit 201 , a hue filtering unit 202 and a saturation filtering unit 203 .

[0098] The green plant distinguishing unit 201 is used to obtain the minimum hue value h of the green plant image element that is different from other background image elements according to the color distribution of the image elements in the field crop growth monitoring image in the HSV color space min , the maximum hue value h max , minimum saturation value s min and the maximum saturation value s max . Other ba...

Abstract

The invention provides a method and system for identifying green plants in a field crop growth monitoring image. The method comprises the steps that firstly, color distribution analysis is conducted on image elements in the field crop growth monitoring image in an HSV color space so as to obtain the hue value range and the saturation value range, different from the ranges of other background image elements, of the green plants; secondly, a band-pass filter BPH (H) based on the hue H and a band-pass filter BPS (S) based on the saturation S are constructed so as to achieve the purpose that other background image elements, except the green plants, in the field crop growth monitoring image can be filtered away when the field crop growth monitoring image passes through the band-pass filter BPH (H) and the band-pass filter BPS (S) in sequence, and then the green plants in the field crop growth monitoring image can be identified through an excess green index and a threshold segmentation method. The method and system can correctly identify the green plants in the field crop growth monitoring images shot under the complex weather conditions and the complicated background.

Description

technical field [0001] The invention relates to the fields of pattern recognition and machine vision, in particular to a method and system for recognizing green plants in field crop growth monitoring images. Background technique [0002] The reduction of arable land, population growth, and frequent natural disasters have forced governments to consider their own food security issues. In order to ensure the stable and high yield of grain, agricultural scientists put forward the concept of "fine agriculture". The core idea is to ensure the health of crops through fine management of all links of agricultural production (such as sowing, fertilization, irrigation, deworming, etc.) growing up. Crop growth monitoring is an important research topic in precision agriculture. [0003] As an important attribute in the process of crop growth, crop growth has become a research hotspot in agronomy. Through crop growth, it can help agricultural scientists analyze the relationship between...
