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 , 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 in such a way that a three-dimensional relief image of at least a part of the overlapping overlap sections is reconstructed as the image by use of an association of the overlapping overlap sections , wherein corresponding sub sections of the working face on the different sections are determined by means of a contrast analysis of the overlap sections 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 , 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 in such a way that a three-dimensional relief image of at least a part of the overlapping overlap sections is reconstructed as the image by use of an association of the overlapping overlap sections , wherein corresponding sub sections of the working face on the different sections are determined by means of a contrast analysis of the overlap sections and associated with one another. <EOS>
