UAV footage of Merino sheep in South Africa

This datasets comprises aerial footage of Merino sheep captured by a UAV. This dataset includes both image and video data. The video dataset consists of both a development and a testing dataset. The dataset was collected over a period of 11 months in two locations in South Africa at a height of 30 m above ground. A DJI Mavic Air 2 was used for data collection. The onboard camera has a 0.5-inch CMOS sensor with a width of 13.2 mm and the lens has a focal length of 8.8 mm. The images were captured at a resolution of 4000 x 3000 while videos were captured at a resolution of 3840 x 2160 and 1920 x 1080 at 30 fps. The image dataset comprises 125 images, totaling 4848 individual instances of sheep. On the other hand, the video dataset includes a development set with 19 videos (4521 unique frames) and a testing set with 10 videos (3045 unique frames). One video containing 250 frames can be excluded from the dataset due to inconsistencies in data representation and blurry frames.本数据集包含由无人机（UAV）采集的美利奴羊航拍影像。数据集涵盖图像与视频两类数据，其中视频数据集分为开发集与测试集两个子集。该数据集的采集周期为11个月，采集场地位于南非两处，飞行高度距地面30米，数据采集设备为DJI Mavic Air 2无人机。其机载相机搭载0.5英寸CMOS传感器，传感器宽度为13.2毫米，镜头焦距为8.8毫米。图像采集分辨率为4000×3000，视频采集分辨率涵盖3840×2160与1920×1080两种规格，帧率均为30 fps。 图像数据集共包含125张图像，总计标注有4848只绵羊个体实例。视频数据集方面，开发集含19段视频，共计4521个独立帧；测试集含10段视频，共计3045个独立帧。另有一段含250帧的视频因数据表征不一致且帧画面模糊，可从数据集中剔除。
