Design and Implementation of a High-precision Ship Target Photoelectric Positioning System

Herein, the design and implementation of a high-precision photoelectric ship target positioning system is introduced to obtain the absolute position and elevation of a moving ship target for real-time measurements in places such as sea-crossing bridges or coastal airports. By integrating high-definition and high-precision optical detection components into the high-definition PTZ equipment, the absolute position and altitude information of the target point can be calculated in real time and reported to the monitoring system. Combined with the guidance of a radar system, it can automatically measure the longitude, latitude coordinates, and altitude of passing ships under unattended conditions. An actual operational test showed that the system had good reliability, measurement accuracy, and application prospects.
