编队训练和人-座舱的自然交互是研制飞行模拟器的关键技术问题。介绍了一套基于混合现实技术研制的具有虚实融合座舱视景的轻量级飞行模拟器系统。该系统的创新之一是使用基于多固定摄像机的虚实融合方法,采用2D四点纹理映射技术将多个摄像机摄取的座舱端交互区域的真实图像添加到虚拟座舱环境中。创新之二是可逼真地模拟真实的编队训练。系统初步试验结果表明,所研制的轻量级飞行模拟器系统增强了学员对飞行座舱环境的真实理解,提高了人-座舱的自然交互能力,在编队多机科目训练方面具有突出的优势,是大型飞行模拟器的有效补充。
Formation training and natural interaction between pilot and cockpit are two key technology issues for developing flight simulator. A lightweight flight simulator system was developed with virtual-real cockpit view using mixed reality technology. First innovation of the system is that a fusion approach of virtual-real scene, based on multiple fixed cameras (MFC), was proposed to superimpose real image streams of cockpit interaction area on virtual graphics of cockpit environment using 2D four points texture mapping. Second one is to simulate formation training realistically. The results of primary test show that the developed lightweight flight simulator is an important complement to current large flight simulator due to its strong enhancement of understanding cockpit environment, effective improvement of natural interaction capability between pilot and cockpit and special predominance over other in terms of multiple planes training such as formation training.
