The Design And Implementation Of The Production Module Of The Surface Products In Thermal Infrared Image Simulation System

The thermal infrared image simulation system is an important subsystem of the XX satellite link simulation platform software developed by the Institute of remote sensing and digital earth and the Henan University.The main task of the simulation platform is to complete the simulation and analysis of the whole image of the space remote sensing thermal infrared and visible near infrared.The main task of this research is to simulate the thermal infrared image in the simulation platform.The research and development of the project team is responsible for the production of thermal infrared subsystem,production subsystem includes a thermal infrared emissivity product module,atmospheric water vapor product module,product module,satellite brightness temperature of earth surface temperature,surface temperature product module module products.This paper is responsible for R &D of surface emissivity products,surface brightness products and surface temperature products.The main work of this paper is as follows:(1)the demand side analysis of the surface production module,including the module for production function,performance and operation environment,and the production module outline design,design of each module class,interface.(2)for surface products related to the production of a variety of algorithms,this paper describes the principle of the algorithm after the selection of the most appropriate algorithm or call,and designed the production process,including the simulation of production of surface emissivity products,surface brightness temperature and surface temperature products products products.The author makes detailed design and implementation of XML documents and codes,and tests them to achieve all the simulation production functions required by the production module of surface products.This paper mainly uses the XML technology,multi threading technology and WindowBuilder visual design techniques and the use of NDVI threshold segmentation method,radiative transfer algorithm,split window algorithm of surface thermal infrared products in the production of production module design and implementation,simulation of production including surface emissivity products,surface brightness temperature and surface products the temperature of products and other products.After testing,the system has achieved all the requirements of the design of indicators.
