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.

本数据集包含采集自2016-2017冬季阿尔伯塔省两条河流——北萨斯喀彻温河（North Saskatchewan River）与皮斯河（Peace River）——的地表冰况数字图像与视频。北萨斯喀彻温河的图像采集采用两种设备：一是安装在埃德蒙顿两座桥梁上的Reconyx PC800 Hyperfire Professional 野外相机（game camera），二是在吉尼西船艇下水点（Genesee boat launch）搭载CGO3 4K相机的Blade Chroma无人机（Unmanned Aerial Vehicle, UAV）。皮斯河的相关数据仅通过无人机在邓维根桥船艇下水点（Dunvegan Bridge boat launch）与沙夫茨伯里渡口（Shaftesbury Ferry crossing）采集。该野外相机以每分钟1帧的频率采集3.1兆像素的静态图像；无人机搭载的相机则可录制最长10分钟的4K视频（等效8.3兆像素）。本数据集包含50张经人工标注的像素级标注图像，涵盖锚冰（anchor ice）、絮状冰（frazil ice）与水体三类目标。为简化标注工作，尺寸较大的3840×2160无人机图像被裁剪为多张1280×1080的子图像；而尺寸较小的2048×1536野外相机图像仅被裁剪以去除相机软件添加的文字信息。
