乌克兰合成车辆数据集（Corolla × BMW 3-Series）包含由OpenAI `gpt-image-2`生成的丰田Corolla和宝马3系轿车的照片级合成图像，场景为乌克兰城市环境。数据集包含150张图像，每张图像从12个乌克兰城市、7种天气条件、5个时间段和6种摄像头类型（行车记录仪、闭路电视、无人机、智能手机、运动相机、壁挂式安全摄像头）的组合中采样生成。数据集旨在用于训练时增强、细粒度分类、模拟到真实的研究以及提示工程研究。每张图像包含制造商（Toyota Corolla或BMW 3-Series）、城市、天气、时间段、摄像头类型和生成提示等元数据。数据集采用CC-BY-4.0许可，并遵循OpenAI API使用政策。

The Ukraine Synthetic Vehicle Dataset (Corolla × BMW 3-Series) consists of photo-realistic synthetic images of Toyota Corolla and BMW 3 Series sedans in Ukrainian urban scenes, generated using OpenAIs `gpt-image-2`. The dataset includes 150 images, each sampled from a combination of 12 Ukrainian cities, 7 weather conditions, 5 times of day, and 6 camera types (dashcam, CCTV, drone, smartphone, action cam, wall-mounted security). The dataset is designed for training-time augmentation, fine-grained classification, sim-to-real research, and prompt-engineering studies. Each image includes metadata such as make (Toyota Corolla or BMW 3-Series), city, weather, time of day, camera type, and the full text prompt used for generation. The dataset is licensed under CC-BY-4.0 and generated in compliance with OpenAI API Usage Policies.
