Ship navigation display system and ship navigation display method

A ship navigation display system provided on a ship includes a communications device, a sensing device, a first computing device, a second computing device and a wearable device. The communications device receives a first coordinate information corresponding to the ship. The sensing device detects a second coordinate information corresponding to a first ship around the ship. The first computing device communicably connected with the communications device calculates a collision probability according to the first coordinate information and the second coordinate information. When the collision probability is greater than the threshold value, the first computing device transmits a collision prediction signal. The second computing device receives the collision prediction signal and projects the second coordinate information to a virtual coordinate of a virtual space. The wearable device receives the virtual coordinate and displays an AR image that includes a virtual object and the first ship in the physical enviro
