CogniLine the digitizing system based on the projection of the line of light sample using a digital projector, whose deformation on the surface of the object  is registered by the digital camera. Implementation process precedes the 3D imaging system calibration (only once if it  the relationships between components or assembly are not altered, and lens parameters are not changed). CogniLine be applied in practice where it is necessary to carry out the measurement of the topography of the object in a quick and simple manner and when the environmental conditions in which recording is carried out, are not adapted to that, eg when the space in which imaging is conducted is illuminated by other light source that could affect the final result of the scanning.
