Embodiment Construction

[0101] The present invention is described in detail below in conjunction with accompanying drawing:

[0102] The present invention provides a method for real-time monitoring of crop growth based on spectral images, which can more conveniently, quickly, and accurately monitor the growth of crops in large-area farmland. The core idea is: firstly, select sensitive wavelengths that have guiding significance for crop growth; then, Obtain the crop image F of the monitored crop under the irradiation of the sensitive wavelength; then, perform image analysis on the crop image F to obtain a crop growth real-time monitoring model; wherein, the crop growth real-time monitoring model fuses image and spectral information; finally, Based on the crop growth real-time monitoring model, the crop growth is monitored in real time. The invention realizes the accurate monitoring of the crop growth information in the farmland, and provides an important guarantee for the rapid monitoring of the farml...

Abstract

The invention provides a real-time crop growth condition monitoring method based on spectrum images. The method comprises steps as follows: determining initial monitoring parameters; screening sensitive wavelengths which have guiding significance in crop growth condition; acquiring crop images F of to-be-monitored crops exposured to the sensitive lengths; analyzing the crop images F to obtain a real-time crop growth condition monitoring model; monitoring the crop growth condition in real time on the basis of the real-time crop growth condition monitoring model. The method has the advantages as follows: images under crop sensitive wave bands are acquired on the basis of a spectrum and image fusion technology, so that the smallest amount of information is provided on the premise that the crop images contain crop growth condition information, follow-up image analysis and processing efficiency is improved, the crop growth condition information can be acquired quickly and accurately, and the crop growth condition monitoring timeliness is improved.

Description

technical field [0001] The invention belongs to the technical field of crop growth monitoring, and in particular relates to a method for real-time monitoring of crop growth based on spectral images. Background technique [0002] Crop growth monitoring is an important research content in the field of agricultural Internet of Things. How to accurately, efficiently and quickly realize the monitoring of crop growth information in large areas of farmland has always been a research hotspot in the field of agricultural Internet of Things. [0003] In the prior art, the image analysis method is mainly used to monitor the crop growth information, specifically: the general camera is used to obtain the full-band image information of the crop canopy, and then the obtained full-band image information is analyzed and processed to obtain the crop growth information. Related Information. [0004] The main problems in the existing monitoring methods are: due to the large amount of informat...
