Night Vision Performance Simulation And The Line Of Sight Assessment System

The visual range represents the performance of LLL(Low-Light-Level) imaging system. There are many parameters which have influence on the visual range, such as the state of the objects, atmosphere, sky radiance, the component's performance of the LLL image system. Thus it is difficult to get the accurate result through calculating.In order to evaluate the performance of the LLL imaging system, this dissertation investigates the simulation of the imaging system based on system simulation and visual simulation. The content of this dissertation is summarized as following:Firstly, the composition, fundamental and parameters which have influence on the performances of the system are analyzed. And a integrated scheme is put forward.And then the 3D models are founded by using Multigen Creator. Some techniques are introduced to optimize the models.At last, the flow chart of software is introduced in detail. And the complete visual simulation system of the LLL imaging system is achieved by using Vega.
