Abstract
A method for testing the function of a system (1). In the method, real models (7, 8) of details of a virtual 3D model (39) of the system are created, with the spatial position and orientation of these real models being captured by a 3D measuring device (11) during the function testing. The determined orientations and positions can be used to manipulate virtual objects (3, 4) in the 3D model (39) in order to display a visual impression (20) in a virtual reality of handling or manipulating the real models (7, 8).
Claims60
A method for testing the function of a system (1), wherein the system is represented as a virtual 3D model (2) comprising virtual objects (3, 4), wherein the virtual objects are characterized as a functional and/or design part of the 3D model, the method comprising:
- providing at least one virtual object (3, 4) for a real model (7, 8),
- aligning a virtual body (13, 14) with the real model (7, 8) at recurring times using a 3D position measurement, wherein the virtual body is constructed as a rigid body formed from measuring points in a fixed arrangement in relation to one another.
- linking the at least one virtual object (3, 4) to the virtual body (13, 14) and bringing the at least one virtual object (3, 4) into a desired position relationship with the virtual body (13, 14), and
- at least one of activating or starting or deactivating or ending the linking (24) between the virtual body (13, 14) and the at least one virtual object (3, 4) by a user, wherein the at least one of activating or starting or deactivating or ending of the linking between the virtual body (13, 14) and the at least one virtual object (3, 4) is independent of a linking between a further virtual body (13, 14) and a further virtual object (3, 4) of the at least one virtual object (3, 4).
(canceled).
The method as claimed in claim 9, wherein the at least two real models (7, 8) are movable with respect to each other with at least one of forced guidance or in a limited way.
A method for testing the function of a system (1), wherein the system is represented as a virtual 3D model (2) comprising virtual objects (3, 4), the method comprising:
- providing at least one virtual object (3, 4) for a real model (7, 8)
- aligning a virtual body (13, 14) with the real model (7, 8) at recurring times using a 3D position measurement and the at least one virtual object is linked to the virtual body (13, 14) and bringing the at least one virtual object into a desired positional relationship with the virtual body (13, 14), and
- producing the real model (7, 8) corresponding to the at least one virtual object (3, 4) in an additive method and is provided with identifiable features for a 3D position measurement, and storing a correspondence (15) between the identified features and the at least one virtual object (3, 4).
A method for testing the function of a system (1), comprising the following steps:
- providing CAD data for the system,
- creating at least one real model (7, 8) for at least some of the CAD data,
- setting up the at least one real model (7, 8) in a 3D measuring apparatus (11),
- displaying a virtual 3D model (2) created from the CAD data by processing at least 3D measurement data from the 3D measuring apparatus (11).

A method for visually displaying 3D data, the method comprising:
- intrinsically determining a field of view (19) of a head-mounted display (16) at recurring times and displaying information moving concomitantly with the field of view (19) in the head-mounted display (16) using a 3D measuring apparatus (11) that is formed independently of the head-mounted display (16) and/or is stationary, and determining a recording pose, predefining the field of view (19), of the head-mounted display (16) and comparing the recording pose with the field of view (19), and visually displaying the 3D data in the field of view (19) with a 3D engine.
A method for visually representing a system, the method comprising:
- intrinsically determining a field of view (19) of a head-mounted display (16) at recurring times, and calculating and visually displaying an air flow as moving 3D data in the form of flow lines in the head-mounted display (16).
