1. A method of providing a warning to a pedestrian using a laser beam, comprising:

  • detecting, by a sensor, objects present in a detection area of a front impact sensor provided on a vehicle;

    generating, by a control unit, a movement path vector of a first moving object that is moving in a direction identical to that of the vehicle among the objects present in the detection area;

    in response to the movement path vector of the first moving object falling within an error range of a movement vector of the vehicle, designating, by the control unit, the first moving object as belonging to a group of laser warning target candidates, and thereafter generating an emission angle of a laser beam; and

    emitting the laser beam through a laser light based on the generated emission angle of the laser beam.
