SYSTEM AND METHOD OF PROVIDING WARNING TO PEDESTRIAN USING LASER BEAM
First Claim
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.

Abstract
Disclosed herein is a system and method of providing a warning to a pedestrian using a laser beam. In particular, objects present in a detection area of a front impact sensor provided on a vehicle are detected. 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, is generated. When the movement path vector of the first moving object falls within an error range of a movement vector of the vehicle, the first moving object is designated as belonging to a group of laser warning target candidates, and thereafter an emission angle of a laser beam is generated. The laser beam is emitted through a laser light based on the emission angle of the laser beam.

8. A non-transitory computer readable medium containing program instructions executed by a processor or controller, the computer readable medium comprising:
-
program instructions that detect objects present in a detection area of a front impact sensor provided on a vehicle; program instructions that generate 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; program instructions that designate the first moving object as belonging to a group of laser warning target candidates, and thereafter generating an emission angle of a laser beam in response to the movement path vector of the first moving object falling within an error range of a movement vector of the vehicle; and program instructions that emit the laser beam through a laser light based on the generated emission angle of the laser beam. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system of providing a warning to a pedestrian using a laser beam, comprising:
-
a sensor mounted in a front portion of a vehicle configured to detect objects present in a detection area of a front impact sensor provided on a vehicle; a control unit configured to generate 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, designate the first moving object as belonging to a group of laser warning target candidates in response to the movement path vector of the first moving object falling within an error range of a movement vector of the vehicle and thereafter generate an emission angle of a laser beam; and a laser light configured to emit the laser beam based on the generated emission angle of the laser beam.
