Abstract

The invention relates to the technical field of data automatic processing, and particularly relates to an HSD data fire point real-time monitoring and automatic analysis system based on Himawari-8. The HSD data fire point real-time monitoring and automatic analysis system based on Himawari-8 can achieve real-time acquisition, batch correction processing and abnormal fire point discrimination of remote sensing satellite data and comprises the following steps: 1) acquiring a Himawari-8 data set; 2) reading and splicing the data sets according to wave band numbers; 3) resampling the resolution data of different wave bands; 4) calculating and processing the data in the step 3): in a stage of processing and calculating the data, processing technical points include original data radiometric calibration, ephemeris table grid calculation, geometric correction based on GCP control points, linear offset fine adjustment of a corrected reference ephemeris table, cloud amount detection removal andbrightness temperature inversion; and 5) waiting for next task initiation. The HSD data fire point real-time monitoring and automatic analysis system based on the Himawari-8 has the advantages that data processing is fast, correction precision is high, cloud layer interference is effectively reduced, and fire point detection accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of automatic data processing, and in particular relates to a Himawari-8-based HSD data fire point real-time monitoring automatic analysis system for real-time acquisition of remote sensing satellite data, batch correction processing, and abnormal fire point discrimination. Background technique [0002] At present, remote sensing monitoring methods for large-scale ground fire points are mainly focused on quantitative comparative analysis and research under high-time resolution satellite data sources (Modis, Himawari, etc.), the main principle is based on the thermal radiation intensity or temperature difference between the fire point and the surrounding normal points judge. Its process mainly includes a series of processing processes such as early data source download, mid-term data reading, calibration, geometric correction, brightness temperature conversion, and later fire point identification algorithm ana...
