+## CARLARain-Data

+* **ExtremeRain:** Based on [CARLARain](https://github.com/kb824999404/CARLARain), we construct an extreme rainy street scene image dataset, ExtremeRain. This dataset contains 8 different street scenes and 3 illumination conditions: daytime, sunset, night. The rainy scenes feature a rain intensity ranging from 5 mm/h - 100 mm/h, covering extreme rainfalls under complex illumination conditions. The dataset contains comprehensive label information to meet the requirements of multi-task visual perception models, including semantic segmentation, instance segmentation, depth estimation, and object detection. We split the dataset into train set and test set according to different scenes.
