摘　　要：三维地形可视化技术是合成视景系统的重要基础技术之一。针对机载合成视景系统地形绘制范围大、硬件计算资源较少和对实时性的要求较高等特点,研究了地形分块调度、层次细节和纹理生成等关键技术,设计并实现了一种适用于机载合成视景系统的地形可视化系统。实验表明,该系统的绘制效果和实时性均能够满足机载合成视景系统的需求。The 3 D terrain visualization is one of the most important technologies of Synthetic Vision System （SVS）. Considering that the airborne SVS has the characteristics of large-scale terrain scene, less computing resource and rigorous real-time requirement, we studied such critical technologies as scheduling of terrain blocks, levels of detail, and texture generating. Based on which, a 3D terrain visualization system suitable for SVS was designed and implemented. The experimental results showed that our terrain visualization system satisfies the requirement of SVS both in visual effect and real-time performance.
