1. Scanner system for scanning an object, the system comprising: a scanner device; a target; and a processor, wherein the scanner device comprises: an emitter for projecting patterned light on the object; and a sensor for capturing images of the object, wherein the target 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, wherein the processor is arranged, in use, to generate geometric data, comprising a three-dimensional model of the object, on the basis of images of the object with the patterned light projected thereon by the emitter, wherein the scanner device further comprises a light source for directionally illuminating the object, and the sensor is arranged to capture images of the object illuminated by the light source, wherein the processor is arranged, in use, to generate sets of photometric data for the object when illuminated from different directions by the light source, and wherein the processor is arranged, in use, to combine 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.
