Researchers have developed a novel unsupervised image translation framework to enable agricultural robots to navigate at night. This system converts daytime RGB images into nighttime near-infrared (NIR) counterparts without requiring pixel-level supervision, allowing daytime semantic labels to be reused for nighttime perception models. The framework incorporates a pre-trained CLIP model to maintain semantic consistency and a visibility mask to handle illumination limitations. Evaluations using the new AgriNight dataset demonstrate improved image quality and downstream semantic segmentation performance for nighttime navigation, with successful real-time autonomous navigation experiments conducted on a physical robot.
