An arrangement for determining an image of at least a part of a working face of a mountain, which has been worked on by a tunnel drilling machine, wherein the arrangement comprises: a rotatable drill head for the tunnel drilling machine for removing material, in particular rock material, of the working face; an image acquisition device arranged at the drill head for acquiring image data of at least a section of the working face; and an image processing device adapted for processing image data of a number of sections of the working face acquired by the image acquisition device, in particular during rotation of the drill head, and for reconstructing the image of at least the part of the working face from the image data of the number of sections of the working face, wherein the image acquisition device comprises a plurality of image acquisition units, in particular video cameras and/or photo cameras, arranged at the drill head, which are adapted for acquiring image data of sections of the working face, wherein the plurality of image acquisition units is arranged at the drill head in such a way that the sections of the working face imaged by these image acquisition units at least partially overlap while forming overlap sections (601, 602), wherein the image acquisition units are adapted to acquire the sections during a turn of the drill head, and wherein the image processing device is adapted to process the image data of the at least overlapping overlap sections (601, 602) in such a way that a three-dimensional relief image of at least a part of the overlapping overlap sections (601, 602) is reconstructed as the image by use of an association of the overlapping overlap sections (601, 602), wherein corresponding sub sections of the working face on the different sections are determined by means of a contrast analysis of the overlap sections (601, 602) and associated with one another. a rotatable drill head for the tunnel drilling machine for removing material, in particular rock material, of the working face; an image acquisition device arranged at the drill head for acquiring image data of at least a section of the working face; and an image processing device adapted for processing image data of a number of sections of the working face acquired by the image acquisition device, in particular during rotation of the drill head, and for reconstructing the image of at least the part of the working face from the image data of the number of sections of the working face, wherein the image acquisition device comprises a plurality of image acquisition units, in particular video cameras and/or photo cameras, arranged at the drill head, which are adapted for acquiring image data of sections of the working face, wherein the plurality of image acquisition units is arranged at the drill head in such a way that the sections of the working face imaged by these image acquisition units at least partially overlap while forming overlap sections (601, 602), wherein the image acquisition units are adapted to acquire the sections during a turn of the drill head, and wherein the image processing device is adapted to process the image data of the at least overlapping overlap sections (601, 602) in such a way that a three-dimensional relief image of at least a part of the overlapping overlap sections (601, 602) is reconstructed as the image by use of an association of the overlapping overlap sections (601, 602), wherein corresponding sub sections of the working face on the different sections are determined by means of a contrast analysis of the overlap sections (601, 602) and associated with one another.
