摘要： The invention relates to a device for evaluating a characteristic of an object. Said device comprises a system (10) for preparing a three-dimensional representation of an object, said representation containing information about the characteristic to be evaluated. The three-dimensional representation is sub-divided into a plurality of partial areas (12) which are then evaluated one by one, each partial area of the plurality of partial areas being examined (14) in a two-dimensional manner, in order to determine data relating to a location in a partial area, in which the characteristic differs from a pre-determined characteristic. Using the data relating to the locations in the individual partial areas, a three-dimensional coherence analysis (16) provides a three-dimensional description of a three-dimensional location, the characteristic of said location differing from the pre-determined characteristic. By sub-dividing the three-dimensional representation into a plurality of partial areas which can be analysed in a two-dimensional manner, effective image processing algorithms can be used. The three-dimensionality can then be achieved again by means of a coherence analysis of the two-dimensional data. In this way, a geometrical reference model is superfluous and the resulting high requirement for memory and calculation time is eliminated.

摘要： The invention relates to a camera for optically recording a screen (10). The screen has a surface, and a predetermined overall resolution is provided for the optical recording. The camera comprises a camera support (12) with an array of camera mounts (14), an array of optical individual cameras (16), an d an image processing device (18) for processing digital individual images of the array of optical individual cameras in order to generate the optical recording of the screen with the predetermined overall resolution. The image processing device is effective in reducing a correction of the individual images with regard to the exactnesses of orientation and/or to parameter fluctuations. A correction resolution that is higher than the overall resolution is used for correction purposes, and a separate correction rule (20) is used for correcting each individual camera. After a successful correction, the corrected overall image is brought to the predetermined overall resolution by combining adjacent pixels. By using good individual cameras, an image of a large-format screen is efficiently and economically obtained while having few artifacts.

摘要： The invention relates to a method for examining an object with respect to information that is present on the object in the form of a relief-like structure. According to the inventive method, an initial height representation of the object is provided (10) which reflects the height profile of the object. The initial height representation of the object is processed using height changes in order to bring into prominence the relief-like structure in a processed representation (12, 14). The processed representation is then evaluated (16) for example by optical character recognition methods in order to extract the information that is given by the relief-like structure. The invention makes it thus possible to automatically and reliably detect information that is applied by means of relief-like structures on an object, for example a vehicle tire.
