1. A scanner system for scanning an object, the system comprising: a scanner device; a target independent of the object; and a processor, wherein the scanner device is a hand-held device and comprises: an emitter for projecting patterned light on the object; and a sensor for capturing images of the object, wherein the object and predetermined geometric features of the target are simultaneously visible to the sensor, and wherein the processor is configured to determine the location of the sensor with respect to the object, wherein the processor is configured, 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 configured to capture photometric images of the object illuminated by the light source, wherein the processor is configured, in use, to generate a set of photometric images for the object when illuminated from different directions by the light source, and wherein the processor is configured, in use, to combine the geometric data, the set of photometric images and location of the sensor with respect to the object for each photometric image, by a rectification process, to output a model comprising geometric information on the object together with photometric information spatially registered with the geometric information.
