图像处理算法的目标场景仿真方法

Target Scene Simulation Method for Image Process Algorithm

在各类光学成像控制、制导算法的开发过程中,需要通过目标视频图像进行实验。由于实际视频数据源缺乏,获取难度大,提供目标场景有局限性,给算法验证带来诸多不便。为解决上述问题,采用虚拟现实技术,结合HLA高层体系结构,从成像特点出发,采用计算机视景仿真技术设计实现了生成目标仿真视频图像的方法,有效解决了实际视频源数量有限,灵活性差的弊端。最终,将目标场景仿真方法应用于侦察型巡飞弹图像导引算法的开发和仿真验证中。结果表明,提出的仿真方法作为实际视频图像数据的有力补充,克服了缺乏实际可靠的视频图像数据源的困难,提高了侦察型巡飞弹图像导引算法的开发效率。

During the development of various optical homing seekers＇ control and guide algorithm, the targets image sequence is always required for validation. But validation has so many inconveniences because of the shortage and limitation of real image sequence data source. So based on the visual reality, HLA, and scenario simulation technolo- gy, according to imaging characteristic, a new target image sequence generation method was proposed to solve the in- conveniences above. Finally, the target scene simulation method was applied in the image based homing seeker development of scout loitering missile. The results show that as a powerful supplement of real image data source, the method can overcome the shortage of data source and bring more development efficiency.
