Abstract

Rainfall, as a common trigger condition in the Safety of the Intended Functionality (SOTIF) framework, can impair autonomous driving perception systems, leading to unexpected functional failures. However, studies focusing on sensor performance degradation under natural rainfall conditions are limited, primarily due to the lack of datasets with detailed rainfall information. To address this gap, this study present RainSense, a multi-sensor autonomous driving dataset collected under natural rainfall conditions, featuring fine-grained rainfall intensity annotations. RainSense was recorded at nine representative intersection scenarios in the campus, where a single dummy target was placed at various distances as a detection target. A laser-optical disdrometer was deployed to continuously measure rainfall intensity (mm/h), while camera images, lidar point clouds, and 4D radar data were synchronously collected under different rainfall levels. In total, the dataset comprises 728 cases, including 145 with clear condition, 214 with light rain, 204 with moderate rain, 98 with heavy rain, and 67 with torrential rain. Each case is segmented into 10-second windows and includes 2D and 3D bounding box labels of the dummy target. To investigate how rainfall affects different perception modalities, perception metrics were applied to each sensor type. Results reveal that under heavy and torrential rain, camera images suffer from blur, while lidar experiences sparse and weakened point returns, both leading to substantial perception degradation. In contrast, radar shows minimal variation across all rain levels, maintaining stable signal characteristics and demonstrating strong resilience to adverse weather conditions. The dataset and benchmark suite will be released open-source at: https://github.com/IVtest-Lab/RainSense.git.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
