A method and device for displaying desired positions in a live image of a construction site. The method mat include recording at least one position-referenced image of the construction site; linking at least one desired position to the position-referenced image; storing the position-referenced image together with desired position linkage in an electronic memory; recording a live image of the construction site, in particular in the form of a video, wherein the live image and the position-referenced image at least partially represent an identical detail of the construction site; retrieving the stored position-referenced image from the memory; fitting the position-referenced image with the live image, so that the desired position linked to the position-referenced image can be overlaid in a position-faithful manner on the live image; and position-faithful display of the desired position as a graphic marking in the live image.

Measurement method, measurement systems and auxiliary measurement instruments for displaying desired positions in a live image

A coordinate measuring and/or stake out device can be designed for being hand-held (one-handed), free carriage and movement by a user. A position giving means is for determination of an actual translational position of the device using an external position reference and an orientation giving means for determination of an actual rotational position of the device, such that the actual position of the device with respect to all six degrees of freedom of the device can be determined. A radiation source is for generation of a radiation beam as measuring and/or marking beam for measuring and/or visually marking of an object point. A beam steerer is for automatic steering of an alignment of the beam, whereby the beam which differ in the manner of automatic steering the beam alignment.

Coordinate measuring and/or stake out device

In a surveying device having a base for positioning the surveying device and a pitch component having an optical beam path for surveying a target, the pitch component is radially and axially mounted and is rotatable in relation to the yaw component in a yaw component, which is movable in relation to the base, on the basis of a rotation body chucked in a self-centering manner in two cavities.

Surveying device having ball-point bearing

A setting tool for driving fastening element in constructional components includes a setting mechanism having a combustion chamber () for generating expanding gases, a piston guide () adjoining the combustion chamber (), a bolt guide () adjoining the piston guide () in the setting direction (), and a drive piston () displaceable in the piston guide (). The piston includes a piston head () and a piston body () connectable along an interface () with the piston head (), the piston head () and the piston body () having, respectively, in an interface region, at least one stop surface () and at least one counter-stop surface () formed by surfaces defining essentially complementary tapering regions.

Setting tool

A combustion-engined setting tool for driving fastening elements such as, e.g., nails, blots, etc. in constructional components includes a combustion chamber () for combusting therein an oxidant-fuel mixture, a turbulence generating element, arranged in the combustion chamber () for creating turbulence of the oxidant-fuel mixture, and a drive for at least partially driving the turbulence generating element () and including a mechanical device () for a pulsed acceleration of the turbulence generating element () and which is activated by the actuation switch () that actuates the setting process.

Combustion-engined setting tool

A combustion-engined setting tool for driving fastening elements in constructional components includes a combustion chamber () for combusting therein a full gas-oxidant mixture, at least one guide element () arranged coaxially with a longitudinal axis () of the combustion chamber () for supporting axially displaceable wall () of the combustion chamber () for an axial displacement along the guide element () which is pivotally supported in a drag bearing (), and a guide cylinder () adjoining the combustion chamber () in which a setting piston () is arranged for an axial displacement therein.
