Crop monitoring method and device based on unmanned plane

Abstract

The invention discloses a crop monitoring method and device based on an unmanned plane, and the method comprises the steps: carrying out the aerial photographing of the crops in a to-be-monitored region through a visible light camera, a near-infrared camera and a thermal imager which are all disposed on the unmanned plane; analyzing the aerial photographing data, fully combining a visible light orthoimage, a thermal imaging orthoimage and an NDVI orthoimage, and analyzing the health condition of the crops accurately, thereby achieving the quick, accurate and efficient determining of the healthinformation of the crops in the to-be-monitored region, and solving problems of low judgment efficiency and lower accuracy caused when a single thermal image or a single NDVI orthoimage is used for recognizing the health condition of the crops. The method and device can be used for the discrimination of the health degree of crops in a better way in a period which is after the emergency of the seedlings and before maturity.

Description

technical field [0001] The invention belongs to the field of crop monitoring, in particular to a method and device for monitoring crops based on an unmanned aerial vehicle. Background technique [0002] According to the prediction of the United Nations Population Division, in 2050, the world's population will increase to 9.1 billion. With the population growth, according to the current agricultural productivity forecast, to solve the food problem of the global population needs to increase the current output by 70%. [0003] Due to the difficulty in the development of cultivated land and the imbalance of cultivated land resources, such as water resources, climate, geographical location and other issues have congenital effects, therefore, increasing the yield per unit area of ​​cultivated land has become a top priority. [0004] my country has a vast territory, and the main agricultural production mode in Northeast China, Inner Mongolia, Xinjiang and other places is the field ...
