Abstract: Some embodiments of the invention relate to a method for capturing a relative position of at least one first spatial point by means of a portable distance measuring device, the method comprising positioning a known reference object, which has known features which may be captured by optical means, said features being arranged in a pattern designed for a resection, at least one first measuring process, comprising measuring a first distance to the first spatial point, and recording a first reference image linked in time with measuring the first distance, the reference object being imaged in the first reference image, and ascertaining the position and orientation of the distance measuring device relative to the reference object comprising identifying the reference object, recalling stored information about the known features of the identified reference object and identifying positions of known features of the reference object in the first reference image.

Abstract: Measurement method where a code projection which is dependent on a three-dimensional position of a code carrier relative to a sensor arrangement is generated on a sensor arrangement, and at least part of the code projection is captured. An angular position of the code carrier with reference to the defined axis of rotation is ascertained and a current measurement position of the measurement component relative to a base is determined, wherein, a position value for at least one further degree of freedom of the code carrier relative to the sensor arrangement is ascertained on the basis of the code projection and is taken into account to determine the current measurement position, and a relative position of the connecting element with respect to the holder and/or the deformation thereof is determined from the position value in the form of a change in shape or size.
