Abstract
A scanning system for creating a 3D model of a surface comprises a first light source configured and arranged to project a first pattern of lines onto the surface. An image capturing device captures an image of the surface with the projected pattern under an angle different from the angle under which the first light source emits light. A computer connected to the capturing device is configured to receive the captured image from the image capturing device and programmed to transform the captured image into a 3D model of the surface. The scanning system furthermore comprises a second light source projecting light of a different wavelength than the first light source. The second light source is configured and arranged to project a coding pattern onto the surface. The coding pattern is projected on the lines of the first line pattern so as to provide a coding to the lines of said line pattern whereby each projected line is identifiable in the captured image.
