Recent advancements in artificial intelligence and sensor technology have promoted increasing interest in maritime autonomous ships. In this paper, we present an overview of the perception and sensing technologies applied in autonomous ship research. We introduce various datasets collected using perception sensors, such as a camera, LiDAR, and marine radar. Object detection and semantic segmentation methods for detecting floating objects and navigable regions using individual sensors are presented. Additionally, sensor fusion methods that integrate data from multiple sensors to enhance detection and navigation capabilities are addressed.
