Research And Implementation Of Simulation System For Remote Sensing Full Link Application Process

Remote sensing technology is widely used in vegetation,atmosphere,military remote sensing monitoring and other industries and fields due to its optimized design in band configuration,spatial-temporal resolution,etc.However,due to the influence of many factors in the acquisition process of remote sensing image,the processing results are easy to produce errors,which to a certain extent limits the development of remote sensing technology and restricts the progress of remote sensing industry.In order to improve the quantitative application level of remote sensing satellite and ensure the accuracy of remote sensing image processing results,researchers use remote sensing simulation model to verify the design parameters of remote sensor,the earth environment and atmospheric conditions,and provide data support for the design of remote sensor and the research of remote sensing algorithm.However,at present,the professional remote sensing simulation software is relatively lacking,with poor universality and high cost.Therefore,based on the research and development requirements of Landsat and the application process of remote sensing data,this paper designs a remote sensing full link application process simulation system.The whole link application process of remote sensing refers to the preprocessing of remote sensing data,production of 3-5 level products and quality evaluation.At the same time,in order to improve the running speed of the system,a parallel model based on the application of remote sensing algorithm is constructed.This dissertation is completed jointly with the students of the project team in the project "satellite earth synchronous data simulation subsystem of national civil space infrastructure land observation satellite common application support platform project".The main research work related to myself is introduced as follows:1.Aiming at the requirement of remote sensing application process simulation system in the current remote sensing industry,and the problems of imperfect system process and incomplete remote sensing application link,a remote sensing full link application process simulation system is proposed.In this system,the whole link application process of remote sensing consists of remote sensing data preprocessing,3-5-level product production and remote sensing image quality evaluation,and the corresponding data processing simulation model is established,which can complete remote sensing data preprocessing simulation,product production simulation and remote sensing image quality evaluation simulation under different resolution satellites.At the same time,the system requirements analysis is compiled and the system model design is completed.2.A parallel model based on the application of remote sensing algorithm is built to solve the problem of large production tasks and many algorithms in the process of system development.Using multi process technology to build parallel model based on algorithm component can make multiple remote sensing tasks execute in parallel;using multi thread technology to build parallel model based on algorithm analysis tree can improve the execution efficiency of remote sensing algorithm,so as to reduce the system response time and improve the system throughput.3.Realize the simulation system of remote sensing whole link application process.The system uses eclipse as the development platform,Java FX as the system framework technology,and Java FX scene Builder(scene builder)as the modeling tool to realize the development of system interface and system simulation function,improve the system scalability and reduce the coupling between modules.The system combines the computer simulation technology with the remote sensing industry’s demand for remote sensing data processing.Facing the whole remote sensing link application process,it conducts the remote sensing data preprocessing simulation,remote sensing product production simulation and remote sensing image quality evaluation simulation,guides the remote sensing application system construction and related algorithm research,and promotes the progress of remote sensing industry.
