Abstract
In a process for determining the 3D coordinates of an object (1), a partial surface of the object (1) is recorded by a 3D measuring device (2), and the 3D coordinates of this partial surface of the object (1) are determined. Additional partial surfaces of the object (1) are recorded by the 3D measuring device (2), and the 3D coordinates of these partial surfaces are determined. The 3D coordinates of the partial surfaces of the object (1) are assembled by a processing device (3). In order to improve this process, the exposures and/or the 3D coordinates of one or more partial surfaces of the object (1) are represented on a head-mounted display (4) (FIG.1).
Claims21
A process for determining 3D coordinates of an object, comprising:
- recording a partial surface of the object by a camera of a 3D measuring device, the 3D measuring device including a projector for projecting a pattern onto the object and the camera for recording images of the object, and determining 3D coordinates of the partial surface of the object,
- displaying the 3D coordinates of the partial surface of the object on a head-mounted display, said head-mounted display being at least semi-transparent,
- observing the object through the head-mounted display while displaying the 3D coordinates,
- moving at least one of the 3D measuring device or the object relative to each other while observing the object through the head-mounted display,
- recording additional and different partial surfaces of the object by the camera of the 3D measuring device, and determining 3D coordinates of the additional partial surfaces,
- assembling the 3D coordinates of the partial surface and the additional partial surfaces of the object by a processing device, and
- displaying the assembled 3D coordinates of one or more of the partial surface and additional partial surfaces of the object on the head-mounted display,
- wherein graphically visualized spatial limitations of the 3D measuring device, in addition to the assembled 3D coordinates, are displayed on the head-mounted display to augment observation through the head-mounted display.
