摘要:

针对极端太空环境下空间目标仿真光学图像在降质效应分析与仿真方面存在的不足,对极端太空环境成像特点和空间目标光学成像降质效应进行了分析,利用高斯滤波对大气散射和点扩散效应造成的成像模糊降质效应进行计算仿真,设计了基于邻域过曝光像元数的光晕伪影效应仿真计算流程方法,并对不同条件下的成像降质效应仿真结果进行了对比分析。本文提出的空间目标光学成像降质效应仿真方法可为极端太空环境下高保真图像数据计算生成提供技术支持和有效途径。

Abstract:

Regarding the existing deficiencies in the analysis and simulation of degradation effects of the simulated optical images of space targets in extreme space environments, this paper analyzes the imaging characteristics in the extreme space environment and the degradation effects of space target optical imaging. Gaussian filtering is employed to calculate and simulate the imaging blurring degradation effects caused by atmospheric scattering and point spread effects. A simulation calculation process method for the halo artifact effect based on the number of overexposed pixels in the neighborhood is designed. Moreover, the simulation results of the imaging degradation effects under different conditions are comparatively analyzed. The simulation method of the degradation effects of space target optical imaging proposed in this paper can provide technical support and an effective approach for the calculation and generation of high-fidelity image data in the extreme space environment.

Key words: space target, imaging simulation, degradation effect, halo artifact
