摘要

为了在Simulink仿真环境下生成用于图像导引仿真的虚拟场景图像数据,基于OpenSceneGraph(OSG)三维渲染引擎,研究了Simulink环境下的场景仿真图像生成软件框架、三维场景离屏渲染技术和OSG、Simulink混合编程技术,设计开发了相机驱动模块和图像生成模块,实现了Simulink环境下对机载相机输出图像的模拟,有效地解决了Simulink环境下进行图像导引仿真时的场景图像数据生成问题,从而很大程度上提高了图像导引算法的开发效率。

Abstract

In order to create virtual scene image used in image guidance simulation under Simulink, based on OpenSceneGraph (OSG), an 3D render engine, the framework of scene graph generation software, off screen rendering, on board camera modeling and mixed programming of OSG and Simulink were studied. A camera drive block and an image generation block named SSGSim were designed to simulate the process of producing onboard camera image, which can solve the problem of scene image generation effectively under Simulink, and image guidance algorithm development efficiency was greatly improved.

Key words： image guidance simulation; off screen rendering; computer vision based landing
