下视景像匹配仿真系统中的数据生成

为了对下视景象匹配算法的性能进行评估,需要构建完善的下视景像匹配仿真系统.针对下视景像匹配仿真中的数据生成问题,全面考虑了实际下视景像匹配系统的数据生成原理及流程,引入了ICCD误差模型、雾景误差模型和姿态畸变模型等噪声和误差模型对实时图生成过程进行仿真.并模拟了实际系统工作时的航线及飞行姿态等相关数据的生成过程,考虑了飞行器实际航线及飞行姿态对各项生成数据的影响,最后提出了一种仿真程度较高的实时图序列及相关数据生成系统.

Data Generation of Down-looking Scene Match Simulation System

To evaluate the performance of the down-looking scene match simulating algorithms,it is necessary to establish a powerful simulating system.This paper faces the data generating problem of down-looking scene match simulation.The noise and aberrance such as ICCD camera's aberration,fog aberration and attitude aberration are included to simulate the generation of the real-time image.And the generating process of the real flight course and attitude is simulated.The influence of the flight course and attitude on the resulted data is also included.Finally,a powerful system is developed.
