1. A traffic event reproduction system comprising:
a server;
a first transmission apparatus configured to transmit first event information including a first event video of a traffic event to the server; and
a second transmission apparatus configured to transmit second event information including a second event video of the traffic event to the server,
the server including:
at least one memory storing instructions, and
at least one processor configured to execute the instructions to:
receive the first event information and the second event information from the first transmission apparatus and the second transmission apparatus;
generate a first three-dimensional model including an object of a party to the traffic event extracted from the first event video and a second three-dimensional model including an object of the party extracted from the second event video;
combine the first three-dimensional model and the second three-dimensional model to generate a combined three-dimensional model in a three-dimensional space including a point corresponding to the occurrence point of the traffic event; and
display a video of the party viewed from a user-specified viewpoint on a display using the combined three-dimensional model.
