Space Target Simulation Dataset in Space-based Detection System

The dataset consists of space target simulation image sequences under a space-based optical detection system. The observation satellite is set to be in a high Earth orbit, observing targets in low Earth orbit.The dataset includes target image sequences under three different illumination backgrounds: strong light glare, non-uniform strong light, and no illumination. Each illumination background contains five sets of target image sequences with different observation axis directions and varying signal-to-noise ratios (SNRs). The simulated time step for each sequence is 5 seconds, with a total of 1,000 frames per sequence. The image resolution is 500×500 pixels, and the images are stored in PNG format.Additionally, each sequence includes a trace folder, which contains:trace.pngtarget_pos.jsonsnr.txt每个序列还包含一个 GroundTruth 文件夹，用于存储 Ground Truth 目标图像。数据目录结构 -glare_spot：强光眩光背景下的目标数据
