摘要： According to the invention, objects can be measured with high precision and flexibility by means of a co-ordinate measuring device, using the following method steps: coarse alignment of the image processing sensor onto the position of the object for measuring, whereby on aligning the image processing sensor, the above is displaced with an acceleration of a1 > 0 mm/s2, and the braking of the image processing sensor and measurement of the position with a moving image processing sensor occurs with an acceleration of a¿2? 0 mm/s?2 ≤ a¿2

摘要： The invention relates to a method for measuring the spatial position and/or opening such as a bore of a work piece by means of a transmitted light process using at least one optical sensor. The aim of the invention is to perform high precision measurements of openings such as bore in a constructively simple manner. To achieve this, at least two parallel sections between the light cone emerging from the opening and at least two working planes are measured by optical sensors, and the axial direction of the opening is calculated using straight lines which extend between the mid-points of the curves thus determined.

摘要： The invention relates to a method and a device for detecting an object point (12) on an object (14) such as a work piece or a tool, by means of a sensor (16). In order to obtain an extremely precise measurement at a high measuring speed, a first detection of the object point (12) is carried out by displacing the sensor (16) in the direction of the object (14) at a first speed V1 and a second detection of the object point (12) is carried out by moving the sensor (16) away from the object (14) at a second speed V2, the actual measured value being determined by the second object point detection.

摘要： The invention relates to an illumination device for illuminating an object to be measured, especially defined for a co-ordinate measuring device or a measuring microscope. Said device comprises a plurality of light sources stemming from a holding element (18, 20, 22, 24, 26, 28, 30, 32, 34, 36). Said light sources have various angles of incidence in relation to an optical axis (14) of an optical instrument, by which means the object can be measured or reproduced. In order to be able to adjust the illumination on various working planes without using a complex mechanism, in order to illuminate an object to be measured or a surface or an edge thereof in an optimum manner, light sources (18, 20, 22, 24, 26, 28, 30, 32, 34, 36) are arranged in the holding element (16) in such a way that the angles of incidence thereof cut the optical axis (14) in the region of working intervals (48, 50, 52, 54, 56) of the optical instrument, said intervals deviating from each other.

摘要： The invention relates to an assembly for the optical-tactile measurement of the structure of an object (12), using a co-ordinate measuring device (10). Said device comprises a contact stylus (18) with a stylus extension that is elastic at least at its end, said extension ending in a stylus element that probes the object. To measure the structure of an object (12) with a high degree of precision and the required coverage, the optical sensor and the contact stylus are integrated into one unit or form a single entity.

摘要： The invention relates to a feeling method for determining the surface characteristics of a test piece comprising a feeler element which is supported on the surface. The position of the feeler element or a position of at least one reticle which is directly assigned to the feeler element is directly detected using an optical sensor. In addition, the surface characteristic is determined while taking the relative movement between the test piece and the feeler element into account.
