UIT-Drone4

UIT-Drone4 is a high-resolution aerial imagery dataset for traffic-related object detection, collected and annotated by the University of Information Technology (UIT). Captured using drones in diverse urban environments, it includes key traffic objects such as pedestrians, motorcycles, cars, and buses. The dataset presents challenges like small object sizes, perspective distortion, and varying lighting conditions, making it a valuable resource for research in aerial vision and intelligent transportation systems.UIT-Drone4 是一款面向交通目标检测任务的高分辨率航空影像数据集，由信息技术大学（University of Information Technology，UIT）采集并标注。该数据集依托无人机在多样化城市环境中完成采集，涵盖行人、摩托车、轿车及巴士等核心交通目标。数据集存在多项典型挑战性场景：目标尺寸偏小、存在透视畸变且光照条件多变，因此成为航空视觉（aerial vision）与智能交通系统（intelligent transportation systems）领域研究的宝贵资源。
