The invention discloses a soil water content remote sensing monitoring method. The method comprises the steps that an unmanned aerial vehicle collects a remote sensing image of a monitoring area; the base station device receives the remote sensing image and analyzes and determines the bare proportion of the soil in the remote sensing image; comparing the exposure proportion with a set proportion threshold value, and determining whether the exposure proportion is smaller than the proportion threshold value or not; if the bare proportion is smaller than a proportion threshold value, starting the unmanned vehicle to go to the monitoring area; the unmanned vehicle collects a soil image in the monitoring area; the base station device synthesizes the remote sensing image and the soil image to form a synthesized image; and analyzing the synthesized image, and determining the soil water content of the monitoring area. The method is not affected by the ground vegetation coverage rate, the information of the soil can be obtained under any condition, and then the accurate soil water content is determined.
本申请公开了一种土壤含水量遥感监测方法,包括:无人机采集监测区域的遥感影像;基站装置接收遥感影像,分析确定遥感影像中土壤的裸露比例;将裸露比例与设定的比例阈值进行比较,确定裸露比例是否小于比例阈值;如果裸露比例小于比例阈值,启动无人车前往监测区域;无人车采集监测区域中的土壤图像;基站装置将遥感影像和土壤图像进行合成,形成合成图像;对合成图像进行分析,确定监测区域的土壤含水量。本申请的方法不受地面植被覆盖率的影响,在任何情况下都能获得土壤的信息,进而确定较为准确的土壤含水量。
