    摘要: The present invention relates to a method and a device for determining the spatial position of a sensor, in which a rough position information initially is determined by rough detection of the position of the sensor, and then the more accurate position of the sensor is obtained by measuring at least three reflectors mounted on the sensor with a laser tracker, wherein the search region of the laser of the laser tracker is limited for the reflectors with reference to the rough position information.

    摘要: In a method for the determination of the 3D coordinates of an object (2), a pattern is projected (1) onto the object (2) and the pattern reflected by the object (2) is taken (3) and evaluated. To improve such a method, a pattern is projected onto a first part region (12) of the object (2) in a first step and the pattern reflected by this part region (12) of the object (2) is taken. In a second step, a pattern is projected onto a second part region of the object (2) and the pattern reflected by this part region of the object (2) is taken. The patterns taken are evaluated.

    摘要: In a method for 3D digitization of an object (1), a plurality of camera images of the object are recorded and assembled to determine the 3D coordinates of the object. To improve such method, pictures are taken from the object (1), from which 2D feature points (11, 12, 13; 21, 22, 23) of the object (1) are determined. The 3D coordinates of the 2D feature points are determined. The 2D point correspondences (32, 32, 22) between the 2D feature points of a picture and the 2D feature points of another picture are determined. Several of these 2D point correspondences are selected, and an associated 3D transformation is determined. The quality of this 3D transformation is determined with reference to the transformed 3D coordinates of the 2D feature points. Valid 3D feature points are determined therefrom. For assembling the camera images of the object (1), the 3D coordinates of the valid 3D feature points are used.

    摘要: A polar modulator arrangement has a first and a second node to receive a digital signal with a first and a second component corresponding to a digital amplitude component and a digital phase component. A digital interpolation filter generates an interpolated first component by interpolating and filtering the first component. A polar modulated radio frequency signal is generated by a combination element as a function of the interpolated first component and the second component.
