AAU Visual Rain Dataset (VIRADA)

The AAU VIRADA dataset contains a total of 215 hours of surveillance video from two different locations in Aalborg, Denmark. The purpose of the dataset is to enable the use of surveillance cameras as surrogate rain gauges.

The ground truth precipitation data comes from two disparate sources: 1) mechanical, tipping-bucket rain gauges and 2), an advanced laser disdrometer.

The footage from the first location, Crossing1, is split into a training (trn) and a validation (val) split. The footage from the second location, Crossing2, is used entirely for testing.

More details on the setup is found in the CVPR Workshop paper:

AAU VIRADA 数据集（AAU VIRADA Dataset）共收录丹麦奥尔堡两处不同地点的215小时监控视频，本数据集旨在将通用监控摄像头作为替代雨量计开展相关研究。

该数据集的地面真值降水数据来源于两类完全不同的数据源：1）机械翻斗式雨量计；2）先进激光雨滴谱仪。

第一处地点Crossing1的监控录像被划分为训练集（trn）与验证集（val）；第二处地点Crossing2的全部监控录像均用于测试。
