STRIDE-ZeroGlab-v2

Dataset Description This dataset comprises 1,046 real grayscale images acquired by sampling 22 rectilinear trajectories under systematically varied illumination conditions. In addition, 40,000 synthetic grayscale images were generated and used for training purposes. The complete dataset, together with the trained model weights, is provided as a compressed archive(**data_weights.tar.gz, approximately 3.9 GB) Archive Contents Data data/real/images/1,046 real grayscale test images data/real/labels_real.jsonGround truth annotations, including keypoints, bounding boxes, and pose information data/synthetic/images/40,000 synthetic training images data/synthetic/split_yolo/YOLO-format dataset split(35,000 training / 5,000 validation / 772 test images) data/synthetic/gan_synth2real_images/Synthetic images translated to the real domain using CycleGAN data/cam_sat.jsonCamera intrinsic parameters and spacecraft model Model Weights weights/odn/YOLO11n object detection network weights provided in PyTorch, ONNX, and TensorRT formats (FP16 and FP32) weights/krn/EfficientNet-B0 keypoint regression network weights provided in PyTorch, ONNX, and TensorRT formats (FP16, FP32, and INT8) Data Acquisition and Characteristics For the real dataset, the target-to-camera distance ranged from 0.33 m to 0.79 m, measured from the geometric center of the physical model. For the synthetic dataset, distances ranged from 0.3 m to 1.0 m. All images were converted to grayscale to improve computational efficiency and to accelerate processing within the developed pose estimation pipeline. Illumination conditions were systematically varied for each test case with respect to: the α and β illumination angles, the position of the sun simulator along the z and y axes, and the intensity of the simulated sunlight.
