The dataset is divided in two folders: calibration and case study. In calibration there are three folders: camera, translation and rotation. In camera there are the .btp files acquired to calibrate the camera. In translation, there are the images of the center of the line. Each picture corresponds to an increase of 0.1 mm. The images are named after each increment. In rotation, there are the images of the laser line. Each picture corresponds to an incremental rotation of 2 degrees. The images are named after each increment. In case study there are two folders: straight and not straight. The straight folder contains the acquired data for a straight billet. The not straight folder contains the acquired data for a not straight billet. Each of these folders contain three folders: profiles, rotation and translation. Profiles contain the .csv file acquired by the laser profilometer. The sub folder cleaned profiles contains just the x and z coordinates of the acquisition. Rotation, contains .btp images acquired with a higher exposure time: all the line is visible. Translation, contains .btp images acquired with a lower exposure time: only the center of the line is visible. In each folder of case study, the files are named according to the position measured by the encoder of the motorized drive.
