Abstract: Provided are a laser irradiation apparatus using a robot arm and a method thereof which can automatically scan an object and irradiate with laser beam to the surface of the object based on the scanned information. The laser irradiation method using a robot, includes: collecting a raw data by scanning an object; constituting a three-dimensional image of the object on the basis of the raw data; setting a region of interest (ROI) on a surface of the object in the three-dimensional image; setting a guide path passing through the region of interest; and irradiating a laser on the surface of the object corresponding to the guide path using the robot arm having an end-effector.

Abstract: Provided is a region division method for laser treatment, and a laser treatment method and apparatus using the same. The region division method for laser treatment according to the present invention divides an area of an object to be treated by laser irradiation into a plurality of treatment regions and includes constructing a three-dimensional image of the object; using the three-dimensional image to obtain a normal vector for each of a plurality of points located on a surface of the object; dividing the points on the surface of the object into one or more groups based on a similarity between the obtained normal vectors; and generating a closed curve including at least some of points grouped into the same group to set a treatment region.

Abstract: Provided are a method of controlling motion pattern for a laser treatment and a laser irradiation apparatus using the same, which can perform the efficient laser treatment.

Abstract: Provided are a laser control method and a laser irradiation apparatus thereof, which can efficiently perform the laser treatment. The laser control method includes a setting step of setting a guide path on a surface of an object; and an irradiating step of irradiating a laser onto the surface of the object corresponding to the guide path, wherein at least one of a fluence or a frequency of the laser is gradually increased at the beginning stage of the laser irradiation and at least one of the fluence or the frequency of the laser is gradually decreased at the end of the laser irradiation.
