Abstract

An arrangement for visual fault inspection of at least one component includes a fault identification unit for identifying a structural fault of the component and for determining at least one piece of fault information, and an overlay device connected to the fault identification unit, configured for context-dependent overlay of the fault information in a component image in real-time.

First claim

What is claimed is:

1 . An arrangement for visual fault inspection of at least one component, comprising:
a fault identification unit configured to identify a structural fault in the component and to determine at least one item of fault information; and an overlay device connected to the fault identification unit and configured to overlay the at least one item of fault information in a context-dependent manner in a component image in real-time.

2 . The arrangement according to claim 1 , wherein the overlay device comprises:
a positioning-finding unit configured to determine exact positioning information about the position of the component and about the position of the user; a processor unit connected to the fault identification unit and to the position-finding unit, the processor unit being configured to process the at least one item of fault information and the positioning information and to integrate the processed information in the component image; and a visualisation unit connected to the processor unit configured to display the component image containing the integrated information of the processor unit.

3 . The arrangement according to claim 1 , further comprising:
a capture unit connected to the processor unit and configured to capture the component image.

4 . The arrangement according to claim 1 , wherein the component image corresponds to a real-time image of the component.

5 . The arrangement according to claim 1 , wherein the visualisation unit comprises one of a portable computer, eyeglasses, contact lenses, a portable screen, and a portable transparent display.

6 . The arrangement according to claim 1 , wherein the at least one item of fault information comprises the pinpointing or the coordinates of the structural fault.

7 . The arrangement according to claim 1 , wherein the at least one item of fault information comprises the severity of the structural fault.

8 . The arrangement according to claim 1 , wherein the positioning-finding unit comprises reference markers for calculating the position of the component and of the user.

9 . The arrangement according to claim 1 , wherein the processor unit comprises a synchronising unit configured to synchronise the movement of the visualisation unit and/or the direction of view of the visualisation unit with the displayed component image.

10 . The arrangement according to claim 1 , wherein the visualisation unit comprises means for pinpointing the structural fault on the displayed component image.

11 . A method for visual fault inspection of a component, the method comprising:
identifying a structural fault on the component; determining at least one item of fault information of the structural fault using a fault identification unit; and overlaying the at least one item of fault information in context-dependent manner in a component image in real-time.

12 . The method according to claim 11 , wherein overlaying the at least one item of fault information comprises:
determining exact information about the position of the component and the position of the user by means of a positioning-finding unit; processing the fault information and the information about the position of the component and the position of the user; integrating the processed information in a component image by means of a processor unit; and displaying the component image containing the integrated information by a visualisation unit in real-time.

13 . The method according to claim 12 , wherein the component image is captured in real time.

14 . The method according to claim 11 , wherein the displayed component image moves according to the movement of the visualisation unit and/or the direction of view of the visualisation unit.

15 . The method according to claim 11 , wherein the processing of the fault information comprises:
categorising the structural fault; determining whether countermeasures are necessary; and initiating counter measures depending on the determination.
