    摘要： A method for recording an image of an object includes projecting a strip pattern onto the object, recording the projected strip pattern as raw image data using a camera, and calculating an image of the object from the raw image data. A strip pattern having a duty cycle of less than 1 can be used to increase measuring precision during measurement of a translucent object, and can eliminate a need for additional contrast agents for a recording of the object.

    摘要： The invention relates to a method for optically scanning the three-dimensional geometry of an object by means of triangulation, in which a pattern (9, 9′) is projected onto the object (7) to be scanned in order to obtain a 3D data set, and the projected pattern (9, 9′) is recorded in an image (40, 41). In a first step for the production of at least one first image (40), a first pattern (9) is projected and in a second step for the creation of at least one further image (40), a further pattern (9′) deviating from the first as regards position or shape is projected onto the object (7) to be scanned and the image (41) is created. The first image (40) and the further image (41) comprise at least one common point (44). The 3D data acquired from the images (40, 41) are merged in a subsequent step on the basis of the 3D data of the at least one common point (44) such that the 3D data acquired from said images (40, 41) agree at least with reference to the 3D data of the common point (44) in the 3D data set.

    摘要： A system, apparatus, method, and computer program product for evaluating an object disposed on an upper surface of an object holder. At least one first frame representing a captured portion of the object is acquired, while the object holder is positioned at each of a plurality of locations. At least one second frame representing a captured portion of at least one other surface of the object holder besides the upper surface is acquired, while the object holder is positioned at each of the plurality of locations. At least one spatial characteristic associated with the captured portion of the object is determined, based on at least one of the acquired frames. A three-dimensional representation of the object can be formed based on the first frames and at least one spatial characteristic.
