ABSTRACT:
Disclosed are a method and a device for establishing a data collection with the aid of at least one imaging apparatus (1, 2, 3) and at least one illumination device (11, 12, 13). According to the inventive method, an object is recorded from at least three different directions while being illuminated from at least three directions in reflected light. Each direction of recording lies essentially opposite a direction of illumination such that at least one contour of the object is visible with an illuminated side and a shaded side thereof from each of the three directions of recording while substantially the entire object is recorded from the at least three directions of recording by the at least one imaging apparatus. The directions of recording and the directions of illumination can be moved in a defined manner at several degrees of freedom relative to the object. The recorded images and/or data derived therefrom are stored in the data collection.
