Abstract
A scanner system and corresponding method, the system comprising: a scanner device (1); a target 17) and a processor (21). The scanner device (1) comprises: an emitter (13) for projecting patterned light and a sensor (12) for capturing images of the object (19). The target (17) has predetermined features visible to the sensor simultaneously with the object for enabling the processor to determine the location of the sensor with respect to the object. The generates a three-dimensional model of the object on the basis of images of the object with the patterned light projected thereon. The scanner device further comprises a light source (14) for directionally illuminating the object (19), and the sensor (12) is arranged to capture images of the illuminated object. The processor generates sets of photometric data for the object when illuminated from different directions. The processor combines the geometric data and photometric data to output a model comprising geometric information on the object together with photometric information spatially registered with the geometric information.
