| Abstract: | The function of dynamic track drawing realized in the ship monitoring system.Based on the function,we could draw the sailing tracks dynamically according to the ship's orientation.Two kernel algorithms are involved during the system developing process,i.e.the algorithms of angular deflection and distance interval value.The practice of system development shows that the proper application of these two algorithms has good effect in the visualization of sailing track. |
