摘要
本研究利用无人机低空遥感平台获取不同生育期玉米冠层多光谱和可见光图像,提取植被指数和纹理特征,分析不同植被指数和纹理特征在水分胁迫条件下对玉米的植株水分的敏感性特征,筛选出具有最高相关性的植被指数和纹理特征,利用线性回归法构建玉米含水量监测模型,以期为农田精准灌溉提供技术支撑。
This study,utilizing a drone low altitude remote sensing platform to obtain multispectral and visible light images of maize canopy at different growth stages,extracted vegetation index and texture features,analyzed the sensitivity characteristics of different vegetation index and texture features to maize plant moisture under water stress conditions,selected the vegetation index and texture features with the highest correlation,and constructed a maize moisture content monitoring model using linear regression method hoping to provide technical support for precision irrigation of farmland.
