"In this thesis, the study of three light profiles (Gaussian, triangular and sinusoidal) is proposed for 3D scanning of objects by displacement of one light line, and appropriate algorithms for each type of profile are implemented. Based on the first study, two additional optical systems were implemented for the 3D scanning of objects: by projection of three-line of RGB light with Gaussian profile and by projection of multi-line of RGB light with Gaussian profile. The 3D shape of objects in all experiments was obtained with high pixel density and resolution."
