    摘要: The invention relates to a method and device for determining the structures of an object by means of a shape-gauge element starting from the stylus extension of an calliper associated to a co-ordinate measuring instrument, which is brought into contact with the object and, afterwards, the spatial position of the a shape-gauge element or of a target mark directly associated therewith is determined by means of an optical sensor. The aim of said invention is to determine any structures with a high measuring accuracy, which requires an accurate determination of the shape-gauge element position to be brought into contact with the object. For this purpose, the invention is characterised in that the two-dimensional position of the shape-gauge element and/or of the target mark is determined by means of a two-dimensional optical position sensors associated with each other on the position point of view and the spatial (3-dimensional) position of the shape-gauge element is calculated on the base of the two-dimensional position thereof.

    摘要: The invention relates to a method for measuring a contour (202) of a workpiece (200) by scanning, using a first and a second sensor. According to the invention, the contour of the workpiece may be measured with high precision and rapidly, especially in the edge region thereof, whereby the contour of the workpiece in a plane (x, y) is recorded by means of the at least two sensors and the information obtained from at least one sensor is used to influence the actions of at least one other sensor. In particular, a mechanical or opto-tactile scanner is operated by means of contour data, obtained by image processing in several windows (206). The contour of the workpiece may also be measured in a direction perpendicular to the x, y plane by means of a laser sensor.

    摘要: The invention relates to a computer tomography method for dimensionally determining features of a measurement object, through which a radiation is passed in several rotational positions, wherein measurement deviations due to the scattered radiation or other physical effects are corrected. In order to avoid or correct measurement deviations in particular due to scattered radiation or due to other physical effects such as beam hardening, afterglow effects, or the like, it is proposed, for example, that the radiographs are corrected by means of synthetic radiographs, calculated from a geometry that is determined in advance or know or from a model of the geometry, wherein the geometry or the model of the geometry at least roughly corresponds to the measurement object.

    摘要: The invention relates to a coordinate measuring apparatus (110) for measuring an object (3), comprising an x-ray sensory mechanism as a first sensory mechanism that is provided with an x-ray source (10) and at least one x-ray sensor (7) which detects the x-rays, and a second sensory mechanism such as a tactile and/or an optical sensory mechanism (8, 11; 9) that can be placed in the x, y, and/or z direction of the coordinate measuring apparatus in relation to the object. In order to be able to easily measure also large-size test objects, the x-ray sensory mechanism (7, 10) can be positioned in the coordinate measuring apparatus (10) according to the second sensory mechanism (8, 11; 9).
