基于无人机影像的农作物生长反演方法及应用

Crop Growth Inversion Method and Application Based on UAV Image

利用无人机获取研究区域的数字影像和多光谱影像,经过数据处理,提取研究区域的植被指数,基于已有的农作物株高和生物量等农业数据,在归一化处理后进行分析,进而反演出农作物长势规律,实现无人机一次数据采集得到农作物同一时期生长规律的监测,提高监测效率,降低监测成本。

The UAV is used to obtain the digital and multi-spectral images of the study area.After data processing,the vegetation index of the study area is extracted.Based on the existing agricultural data such as crop height and biomass,the analysis is carried out after normalization,and the crop growth law is then reflected.It realizes the monitoring of crop growth law in the same period by UAV data acquisition,which can improve the monitoring efficiency and reduce the monitoring cost.
