基于无人机热成像的作物冠层温度测量系统

Crop Canopy Temperature Measurement System Based on UAV Thermal Imaging

植物冠层温度能够反映土壤水分以及作物的缺水情况,要研究作物的含水量,土壤的水分必须要知道作物的冠层温度。本文设计了一个无人机热成像的植被冠层温度测量系统,通过搭载热成像摄像头的无人机对农田作物进行拍照,在经过图像处理得到作物冠层的像素值,使用非均匀校正技术得到像素点与温度的关系,最后可得出作物的冠层温度。本系统实现了自动检测农田作物冠层温度的功能,从而可以及时了解农田的土壤水分情况,进一步对缺水农田进行灌溉。

Plant canopy temperature can reflect soil moisture and crop water shortage.In order to study crop moisture content,soil moisture must know crop canopy temperature.In this paper,the design of a UAV thermal imaging,vegetation canopy temperature measuring system using thermal imaging camera UAV photograph field crops,in the image processing to obtain crop canopy of pixels,use pixels and non-uniform correction technology is the relationship between temperature,finally can draw crop canopy temperature.This system has realized the function of automatic detection of crop canopy temperature,so as to timely understand the soil moisture situation of the farmland,and further irrigate the farmland with water shortage.
