基于OpenGL成像机理的飞行器姿态模拟

Aircraft attitude simulation based on OpenGL imaging mechanism

针对当前块匹配方法进行飞行器姿态视景模拟的拟合度不高的问题,提出一种基于OpenGL成像机理的飞行器姿态模拟方法,进行飞行器姿态的3D模型建模和纹理映射处理,采用模板匹配技术进行飞行器姿态模型的状态信息特征分析和渲染,实现飞行器姿态的实体模型三维重构。在OpenGL环境中进行实体建模,仿真结果表明,采用该方法进行飞行器姿态模拟的拟合精度高,图像渲染的输出信噪比高于传统方法,具有较好的视景仿真效果。

Since the current block matching method has low fitting degree of the aircraft attitude visual simulation, an air- craft attitude simulation method based on OpenGL imaging mechanism is proposed. The 3D model was modeled and the texture was mapped for the aircraft attitude. The template matching technology is used to analyze and render the state information charac- teristics of the aircraft attitude model to reconstruct the 3D solid model of aircraft attitude. The solid was modeled in the OpenGL environment. The simulation results show that the method has high fitting accuracy of the aircraft attitude simulation and good visual simulation effect, and its output signal-to-noise ratio of the image rendering is higher than that of the traditional methods.
