Abstract:
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; emitting the laser beam through a laser light based on the generated emission angle of the laser beam; generating a movement path vector of a new moving object when the new moving object other than the first moving object designated as belonging to the group of laser warning target candidates is present in the detection area; designating the new moving object as belonging to the group of laser warning target candidates when the movement path vector of the new moving object falls within the error range of the movement vector of the vehicle; and designating the new moving object as belonging to a group of laser warning exception candidates when the movement path vector of the new moving object does not fall within the error range of the movement vector of the vehicle.
