Synthetic Car Dataset

Vehicle detection is a very important aspect of computer vision application to aerial and satellite imagery, facilitating activities such as instance counting, velocity estimation, traffic predictions, etc. The feasibility of accurate vehicle detection often depends on limited training datasets, requiring a lot of manual work in collection and annotation tasks. Furthermore, there are no known publicly available datasets. Our aim was to construct a pipeline for synthetic dataset generation from aerial imagery and 3D models in Blender software. The dataset generation pipeline consists of seven steps and results in a wished number of images with bounding boxes in YOLO and coco formats. This synthetic dataset has been produced following the steps described in this pipeline. It consists of 5000 2048x2048 images with cars inserted into the roads and highways at the images without cars from all over the world. We believe that this dataset and the respective pipeline might be of great importance for vehicle detection, facilitating the customizability of the models to specific needs and context.车辆检测是航空与卫星影像计算机视觉应用领域的重要研究方向，可辅助实现目标实例计数、速度估算、交通预测等诸多任务。精准车辆检测的落地可行性往往受限于训练数据集的匮乏，且数据采集与标注工作需耗费大量人力成本。此外，目前尚无公开可用的同类标注数据集。本研究旨在构建一套基于Blender软件的航空影像与三维模型合成数据集生成流水线。该数据集生成流水线共包含七个步骤，最终可生成指定数量的标注影像，其边界框标注支持YOLO与COCO两种格式。本研究依照上述流水线步骤生成了该合成数据集。该数据集包含5000张分辨率为2048×2048的影像，素材取自全球范围内的无车航拍影像，通过在道路与公路场景中插入车辆生成。我们认为，该数据集与配套生成流水线对车辆检测任务具有重要价值，可助力模型针对特定场景与需求实现定制化优化。
