基于目标可见光散射特性的空间目标成像仿真研究

Imaging Simulation of Space Target Based on Target's Visible Scatter Characteristics

为使空间目标可见光成像仿真尽可能反映实际在轨工作状态,提出了一种基于目标可见光散射特性的空间面目标成像仿真方法。根据具体试验场景实时求解跟踪星观测相机、目标星和太阳三站间的相对位姿关系,在事先建立的覆盖全过程的目标可见光散射特性图像数据库中查询相应图像,由相机成像模型,实现空间目标的高逼真度可见光成像实时在线仿真。可为天基空间目标探测、识别与跟踪算法的研究提供较接近真实场景的仿真图像。

In order to make the visible images of space target indicating its active state in orbit as real as possible,a kind of method for space surface target imaging simulation based on target visible light scattering characteristics was proposed in this paper.According to a specific experiment scene,the relative pose parameters among target spacecraft,observation camera and the sun were solved in real-time.The corresponding target image was queried from the image database which was built in advance and can cover all the states of the specific experiment process.To combined with the camera imaging model,the online real-time imaging simulation with high fidelity was implemented,which provided a good foundation for the researches of space-based target detection,recognition and tracking techniques.
