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:
