Study On Scene Simulation For The Performance Evaluation Of Electro-Optical Sighting System

The fidelity of background has a direct impact on the reliability of the performance evaluation of electro-optical sighting system, so establishing a virtual simulation scene with realistic background for electro-optical sighting system is very important.This paper using visual simulation software Creator and Vega Creates a scene simulation system based on real background from the imaging principle of scene simulation. Firstly, the basic framework of the scene simulation system based on real background image is described with reference to the principle of scene simulation. Secondly, the process of reproducing the real three-dimensional scene using two-dimensional background image is discussed. Then, the solution of controlling image size, motion paths and local spray in the simulation of the three-dimension object model is described, which is from the principle of electro-optical imaging and the characteristics of human vision. Finally, a virtual scene simulation system based on two-dimensional background image is built using MFC platform with simulation software Vega, which is integrated into the semi-physical simulation platform and debugged, and the experiment results well.
