Embodiment 1
[0044] like figure 1 It is the process flow of the remote sensing tobacco field identification method in the Jiangnan area based on the improved vegetation index in the embodiment, and the specific steps are as follows:
[0045] Step 1: Obtain multi-temporal synthetic aperture microwave radar remote sensing images (Sentinel No. 1) and visible and near-infrared multispectral remote sensing images (Sentinel No. 2) for the entire growth period of tobacco in the tobacco field area.
[0046] The selection principles of data sources are based on factors such as monitoring objectives, local systems and economy. The entire growth period of tobacco refers to several main growth periods from transplanting to harvesting of tobacco, including: transplanting, clustering, vigorous growth, budding, maturity, and harvesting period. Step 1 of this embodiment can obtain multispectral data of visible light and near infrared (Sentinel No. 2) and synthetic aperture microwave radar data (Sentinel ...
