Abstract: A method of performing and monitoring a processing step on a workpiece using a system having a projector, a photogrammetric device and a control unit knowing the relative position of the projector and the photogrammetric device, comprises the following steps: referencing to determine a pose of the workpiece with respect to the projector and the photogrammetric device in a predetermined coordinate system; projection of a work instruction onto the workpiece; processing of the workpiece by a worker; and monitoring of the processing by scanning at least a portion of a surface of the workpiece, wherein all steps, with the exception of the processing by the worker, are performed by the device and wherein all steps are performed at the same workstation within a framework of an integrated process.

Abstract: A system for visually displaying information on real objects has a projection unit that graphically or pictorially transmits an item of information to an object, and a dynamic tracking device with a 3D sensor system that determines and keeps track of the position and/or orientation of the object and/or of the projection unit in space. A control device adapts the transmission of the item of information to the current position and/or orientation of the object and/or of the projection unit as determined by the tracking device. An associated method for the system determines the current position and/or orientation of the object and/or of the projection unit in space, graphically or pictorially transmits an item of information to the object on the basis of the position and/or orientation as determined, detects and determines any changes, and adapts the transmission of the item of information to the changed position and/or orientation.

Abstract: A method for measuring a position of an element of a structure includes the steps of: attaching a receiving device to the element at a measurement position; attaching a first reference device to the receiving device; determining a first measurement point with a first measurement device adapted to measure a position of the first reference device; removing the first reference device; attaching a second reference device to the receiving device; and determining a second measurement point with a second measurement device adapted to measure a position of the second reference device.
