Method for calibrating a laser work system
P202431039
Laser decoationg or marking involves projecting a laser light that scans the entire surface to be stripped or marked. The projection can be performed on a 2D or 3D surface. To align the 3D stripping template with the actual surface in front of the laser, it is necessary to measure the real 3D surface to be stripped. If the measurement is carried out with a 3D camera, it is necessary to know the camera-laser transformation to express the measurements taken by the 3D camera from the laser's point of view. The objective is to patent the method for calibrating the camera-laser system in 3D space, which allows for the calculation of both the intrinsic parameters of the laser and the extrinsic parameters that represent the camera-laser transformation. With this calibration, it will be possible to express the measurements taken by the camera from the laser's point of view, thereby ensuring that the stripping template aligns perfectly with the surface."
