Rainfall depth is important meteorological information. Generally, high spatial resolution rainfall data such as road-level rainfall data are more beneficial. However, it is expensive to set up sufficient Automatic Weather Systems to get the road-level rainfall data. In this paper, we proposed to use deep learning to recognize rainfall depth from road surveillance videos. To achieve this goal, on the one hand, we collected new video data sets and proposed an estimation procedure to calculate refined rainfall depth from the original meteorological data. On the other hand, we proposed a new deep learning architecture named Temporal and Spatial Segment Networks (TSSN) for rainfall depth recognition. Under the TSSN framework, we utilized the video frame, the differential frame, as well as the optical flow image for rainfall depth recognition. The experimental results show that the combination of the video frame and the differential frame is a superior solution for rainfall depth recognition. The comparative experiments show that TSSN significantly outperforms other adopted methods and has higher robustness against camera movement.
