The key to realizing autonomous navigation in complex maritime environments, especially in accomplishing obstacle detection and tracking tasks, lies in the understanding ofEfficient perception of the sea surface environment<\/span><\/strong>This is why the integration of multiple sensors, including cameras, radar, IMUs (Inertial Measurement Units) and GPS (Global Positioning System), allows for more comprehensive and accurate data collection. As a result, more comprehensive and accurate data on the marine environment can be collected through the integration of multiple sensors, including cameras, laser radar, IMUs (Inertial Measurement Units) and GPS (Global Positioning System). However, such a system would also further involveTime Synchronization<\/span><\/strong>\u3001 Data Transfer<\/strong><\/span>\u8207Storage and Environmental Adaptability<\/span><\/strong>And so on.<\/span><\/span><\/p>\n
