遥感领域的深度学习进展依赖大规模标注数据,但获取几何、辐射及多域任务的高质量真值仍成本高昂且难以实现。尤其缺乏精确深度标注、可控光照变化及多尺度配对图像,制约了单目深度估计、域适应和超分辨率的发展。本文提出SyMTRS,一个基于高保真城市仿真管道生成的大规模合成数据集。该数据集包含2048×2048高分辨率RGB航拍图像、像素级精确深度图、用于域适应的夜间图像版本,以及适用于超分辨率(x2、x4、x8倍)的对齐低分辨率版本。与现有仅专注单一任务或模态的遥感数据集不同,SyMTRS是统一的多任务基准,支持几何理解、跨域鲁棒性与分辨率增强的联合研究。文中详述数据生成流程、统计特性及其在现有基准中的定位。SyMTRS旨在通过提供完美几何真值与一致多域监督,弥合遥感研究的关键差距。相关结果可从GitHub仓库复现:https://github.com/safouaneelg/SyMTRS。

原文摘要 · Abstract (English)

Recent advances in deep learning for remote sensing rely heavily on large annotated datasets, yet acquiring high-quality ground truth for geometric, radiometric, and multi-domain tasks remains costly and often infeasible. In particular, the lack of accurate depth annotations, controlled illumination variations, and multi-scale paired imagery limits progress in monocular depth estimation, domain adaptation, and super-resolution for aerial scenes. We present SyMTRS, a large-scale synthetic dataset generated using a high-fidelity urban simulation pipeline. The dataset provides high-resolution RGB aerial imagery (2048 x 2048), pixel-perfect depth maps, night-time counterparts for domain adaptation, and aligned low-resolution variants for super-resolution at x2, x4, and x8 scales. Unlike existing remote sensing datasets that focus on a single task or modality, SyMTRS is designed as a unified multi-task benchmark enabling joint research in geometric understanding, cross-domain robustness, and resolution enhancement. We describe the dataset generation process, its statistical properties, and its positioning relative to existing benchmarks. SyMTRS aims to bridge critical gaps in remote sensing research by enabling controlled experiments with perfect geometric ground truth and consistent multi-domain supervision.
