Abstract
In the challenging realm of object detection under rainy conditions, essential for autonomous driving systems, visual distortions significantly hinder accuracy. This paper introduces Rain Adapt Faster RCNN (RAF-RCNN), an innovative end-to-end approach that effectively merges advanced deraining techniques with robust object detection. Our method streamlines the model architecture by integrating rain removal and object detection into a single process, using a novel feature transfer learning approach for enhanced robustness under rainy conditions. By employing the Extended Area Structural Discrepancy Loss (EASDL), RAF-RCNN enhances feature map evaluation, leading to significant performance improvements. In quantitative testing of the Rainy KITTI dataset, RAF-RCNN achieves a mean Average Precision (mAP) of 51.4% at IOU [0.5, 0.95], exceeding previous methods by at least 5.5%. These results demonstrate RAF-RCNN's potential to significantly enhance perception systems in intelligent transportation, promising substantial improvements in reliability and safety for autonomous vehicles operating in varied weather conditions.
