title: Space Target Simulation Dataset in Space-based Detection System

description: 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
  --snr1: First set of target image sequences
    ---GroundTruth: Ground truth target image sequences
      ----0-999.png: Ground truth images
    ---trace: Target information
      ----snr.txt: Average SNR of the image sequence
      ----target_pos.json: Target center position information
      ----trace.png: Target trajectory image
    ---0-999.png: Simulated target images
  --snr2
  ...
  --snr5


-no_uniform: Target data under non-uniform strong light background
  --snr1
  ...
  --snr5


-no_light: Target data under no illumination conditions
  --snr1
  ...
  --snr5
该数据集提供了不同光照条件下空间目标的真实模拟，支持空间目标检测算法的研发。
