Problems solved by technology

[0005] Judging from the current research results, there are many researches on the fire point monitoring algorithm based on MODIS and AVHRR sensors at home and abroad, and the fire point algorithm is relatively mature, but the spatial resolution of the two sensors is 1000m and 1100m respectively, and the spatial resolution is relatively low. Still in the research stage, failed to effectively and continuously monitor the operation of farmland straw burning sites

Abstract

The invention provides a remote sensing image monitoring method for farmland burning fire points. The method can use infrared, multi-spectral and land use data, and fire monitoring models to extract farmland burning points in multiple dimensions, thereby improving the low space of the original monitoring sensor. resolution, the invention can automatically, quickly and accurately identify the fire point of farmland burning, greatly improves the accuracy rate of fire point identification of farmland burning, and realizes the automation and precision of commercial fire point monitoring of farmland burning.

Description

technical field [0001] The invention relates to the technical fields of farmland fire monitoring and remote sensing, in particular to a method for monitoring farmland burning fire points using remote sensing images. Background technique [0002] Field crop burning plays an important role in biomass burning. It mainly refers to the incineration of surface biomass remaining after harvesting seeds of crops such as wheat, rice, corn, potatoes, oilseeds, cotton and sugar cane. Surplus crops contain a large amount of elements such as C, H, O, N and S, and their combustion will produce a series of substances, such as CO2, CO, CH4, N2O, NOX, suspended particulate matter and some organic hydrocarbons and toxic and harmful substances, etc., especially A large amount of direct combustion in the field will cause serious air pollution in a short period of time. With the improvement of crop yield, the total amount of agricultural straw has increased rapidly. However, in recent years, t...
