Alberta River Ice Segmentation Dataset

This dataset provides digital images and videos of surface ice conditions were collected from two Alberta rivers - North Saskatchewan River and Peace River - in the 2016-2017 winter seasons.Images from North Saskatchewan River were collected using both Reconyx PC800 Hyperfire Professional game cameras mounted on two bridges in Edmonton as well as a Blade Chroma UAV equipped with a CGO3 4K camera at the Genesee boat launch.Data for the Peace River was collected using only the UAV at the Dunvegan Bridge boat launch and Shaftesbury Ferry crossing.The game camera captured 3.1 megapixels resolution still images at one-minute frequency while the UAV camera captured 4K videos (8.3 megapixels) of up to 10 minutes duration. It includes 50 manually labeled images with pixel-wise labels for 3 claases- anchor ice, frazil ice and water.Large 3840x2160 UAV images were cropped into several 1280x1080 images to make labeling more convenient while the smaller 2048x1536 game camera images were only cropped to remove text information added by the camera software.

本数据集提供了2016-2017年冬季期间从艾伯塔省的两条河流——北萨斯喀彻温河和和平河——收集的表面冰情数字图像和视频。北萨斯喀彻温河的图像通过安装在不列颠哥伦比亚省埃德蒙顿的两座桥梁上的Reconyx PC800 Hyperfire专业游戏相机以及配备CGO3 4K相机的Blade Chroma无人机在Genesee码头起飞点收集。和平河的数据仅使用无人机在Dunvegan桥码头起飞点和Shaftesbury渡口收集。游戏相机以一分钟一次的频率捕捉了3.1兆像素分辨率的静态图像，而无人机相机则捕捉了长达10分钟的4K视频（8.3兆像素）。数据集包含50张手动标注的图像，每张图像都有针对锚冰、冰花冰和水三个类别的像素级标签。将大型的3840x2160无人机图像裁剪成多个1280x1080图像，以便于标注，而较小的2048x1536游戏相机图像则仅裁剪以去除相机软件添加的文本信息。
