In view of the limitations of the mathematical method used in the
container terminal logistics system, this paper uses Unity3D to establish a
computer simulation model for the container automated yard, which dynamically
displays the operation process of the container automated yard logistics system
in real time. Through the plane four-parameter coordinate conversion method and
by taking the Shanghai urban construction coordinate system as the medium, it
completes the conversion from the satellite positioning reference ellipsoid
coordinates to the three-dimensional virtual scene coordinates. The example
results show that the method is reliable and practical, improves the accuracy
and efficiency of positioning, and provides a reliable reference basis for the
container terminal logistics system.
