Research On Visual Simulation Technology Of Solar-blind Ultraviolet Imaging Based On ViewWterra

In recent years,the solar-blind ultraviolet(UV)detection technology has become a research hotspot for researchers with its advantages such as low background interference,low false alarm rate,high sensitivity,and high resolution,and has broad prospect of application.In this thesis,research on solar-blind UV detection technology is carried out.Centering on the characteristics of solar-blind UV atmospheric transmission,based on the vieWTerra visual simulation platform,a solar-blind UV imaging visual simulation system is developed.First of all,this thesis starts from the characteristics of solar-blind UV atmospheric transmission and conducts research from both theoretical and experimental perspectives.The UV atmospheric transmission model based on Bouggner’s law,the transmission distance and wavelength model based on Pc Mod Win,the temperature and humidity model of UV light source,and the voltage and distance model of corona discharge are obtained.Secondly,based on the built simulation system framework and software and hardware platforms,a solar-blind UV imaging visual simulation system is developed.Using 3ds Max modeling software,a 3D model of the high-voltage pole has been obtained and imported into the vieWTerra visual simulation platform.As the simulation target,the insulator is emphasized.And then,in the Visual Studio 2012 development environment,the Microsoft Foundation Classes(MFC)interface is developed using C++ language,and the Dynamic Data Exchange(DDE)is used to communicate the MFC interface with vieWTerra to realize the real-time control of the vieWTerra visual simulation platform.Simulation content can be selected and simulation parameters can be set.Next,according to the experimental UV video source,a real-time effect algorithm of solar-blind UV simulation is designed,which includes two cases of UV light source and corona discharge.The image fusion algorithm used in this thesis,weighted average image fusion algorithm,is introduced.Finally,the wavelength and distance model simulation based on Pc Mod Win,the temperature and humidity model simulation of UV light source and the voltage and distance model simulation of corona discharge are realized on the vieWTerra simulation platform.The corona discharge realizes the dual-channel image fusion simulation.The fidelity and rationality of the simulated images are verified by comparison.
