In maritime navigation, radar is the standard sensor for detection of obstacles or ships. In short range radars, the radiation pattern is too narrow for marine applications. The laser technology is highly efficient in precision detection over short ranges.
Marine traffic from boats to ships can be detected and robustly tracked. The bridge height estimation is precise. Narrow waterways, river banks and bridge columns are correctly detected. The pier and lock chamber sketches are reliable. The laser maritime navigation system is based on laser rangefinder scanner technology for obstacle avoidance and precise maneuvering operations.
The components of a laser ship tracking system include the laser range finder, the scanner and data processing and a display unit. The multiple-target tracking problem is solved using filtering techniques and algorithms for continuous tracking of every individually detected observation.The purpose of using lasers in the berthing system is to measure the speed of approaching ships with great accuracy thus ensuring a safe berthing. Laser tracking is considered an intelligent solution for simplifying ship speed measurements.
The laser technology can be considered a favorable alternative to the radar-based techniques that are not full proof for accurate short range exploration, safety in ship operations and improving efficiency. The laser tracking system serves as a navigational aid for more efficient water transport navigation and avoidance of accidents.
