Problems solved by technology

[0002] As we all know, rice, as an important food crop in the world, is widely distributed in my country. Studying the distribution of rice planting can effectively estimate the rice yield, and then provide a strong guarantee for national policy guidance and food enterprises. However, the existing remote sensing technology is generally used The single extraction calculation method has a low accuracy rate. In addition, although there are drones for precise calculations, the range of calculations is limited. UAV calculations are often used to estimate the rice yield when enterprises plant on a large scale, and it is difficult to conduct large-scale calculations. accurate measurement

Abstract

The invention provides a rice extraction method based on GF-1 and MODIS space-time fusion and relates to the field of crop determination. A GF-1 data receiver, an MODIS data receiver, a data processing center and a sample collection device are utilized. The method comprises the following steps thatGF-1 satellite surface image data is received by a GF-1 data receiver; meanwhile, the MODIS data receiver receives the real-time surface reflectance data, the surface image data and the real-time surface reflectance data are fused through preset software in the data processing center to form a real-time NVDI comparison data tree, and the NVDI comparison data tree can effectively identify and extract rice.

Description

technical field [0001] The invention relates to the field of crop measurement, in particular to a rice extraction method based on the time-space fusion of GF-1 and MODIS.
