1. A 4-dimensional path display method for an unmanned vehicle using a point cloud, the method comprising:
automatically defining a point in a cloud-based 3-dimensional airspace space for generating a flight path of an unmanned vehicle;
automatically selecting a starting point among space vector points in the cloud-based 3-dimensional airspace space;
automatically predicting a space vector point of a flightable area based on weather information and wind strength information at the selected starting point, and size information of the unmanned vehicle, and displaying information on the point as a point size;
automatically generating a departure corridor by reflecting the point size and displayed information of each point;
automatically selecting a corridor constitution type and an obstacle detection avoidance type;
automatically constituting n corridors based on a size of displayed points;
automatically generating the flight path based on a point spacing, the point size, and display information of each point in the point cloud; and
automatically generating and automatically displaying the flight path of the unmanned vehicle by using the point cloud in the cloud-based 3-dimensional airspace space.
