Abstract

A system for characterizing manual welding exercises and providing valuable training to welders that includes components for generating, capturing, and processing data. The data generating component further includes a fixture, workpiece, at least one calibration device having at least two point markers integral therewith, and a welding tool. The data capturing component further includes an imaging system for capturing images of the point markers and the data processing component is operative to receive information from the data capturing component and perform various position and orientation calculations.

Claims

1. A support frame for a welding system, the support frame comprising:

(a) a stand including;

(i) a base;

(ii) a vertical support column extending from the base; and

(iii) a flat assembly extending from the support column, the flat assembly operable to support a workpiece including at least one joint to be welded; and

(b) a cage having a plurality of mounts, each of the mounts being operable to removably attach a camera at a different location on the cage;

wherein a first camera is mounted to the cage using one of the mounts at a first location on the cage;

wherein a second camera is mounted to the cage using one of the mounts at a second location on the cage;

wherein a third camera is mounted to the cage using one of the mounts at a third location on the cage;

wherein the cage is operable to assume one of multiple positions relative to the stand; and

wherein movement of the cage simultaneously moves the first camera, the second camera, and the third camera in relation to the stand.

2. The support frame of claim 1, wherein the flat assembly is connected to the support column by a collar, and

wherein the collar is operable to slide on the support column between a first position and at least one second position.

3. The support frame of claim 1, wherein the flat assembly includes at least one clamp for securing the workpiece thereon.

4. The support frame of claim 1, wherein the flat assembly is perpendicular to the support column.

5. The support frame of claim 1, wherein the flat assembly is parallel to the support column.

6. The support frame of claim 1, wherein the flat assembly is operable to assume a plurality of different positions.

7. The support frame of claim 1, wherein the stand includes a computer mounted thereon, the computer operable to receive data from the first camera, the second camera, and the third camera.

8. The support frame of claim 7, wherein the stand includes a monitor mounted thereon, the monitor operable to display data from the computer.

9. The support frame of claim 1, wherein the cage includes one or more legs, the legs and the base being operable to hold the support frame and its components on a support surface.

10. The support frame of claim 9, wherein a length of each of the legs is adjustable.

11. The support frame of claim 1, wherein the cage includes between three and twenty mounts.

12. The support frame of claim 1, wherein the cage includes at least four mounts.

13. The support frame of claim 1, wherein a height of the first camera is different than a height of the second camera and a height of the third camera,

wherein a height of the second camera is different than a height of the first camera and a height of the third camera, and

wherein a height of the third camera is different than a height of the first camera and a height of the second camera.

14. The support frame of claim 13, wherein at least one of the first camera, the second camera, and the third camera is positioned above the flat assembly, and

wherein at least one of the first camera, the second camera, and the third camera is positioned below the flat assembly.

15. The support frame of claim 1, wherein the stand and the cage are removably attached to one another.

16. The support frame of claim 1, wherein the stand and the cage are placed adjacent to one another without any physical connection.

17. The support frame of claim 1, wherein the cage includes a first pair of mounts that are aligned with one another about an axis parallel to a first axis of the flat assembly,

wherein the cage includes a second pair of mounts that are aligned with one another about an axis parallel to a second axis of the flat assembly,

wherein the cage includes a third pair of mounts that are aligned with one another about an axis parallel to a third axis of the flat assembly, and

wherein the first axis, the second axis, and the third axis are perpendicular to one another.

18. The support frame of claim 1, wherein the cage includes at least one mount with no camera interfaced therewith.

19. The support frame of claim 1, wherein the cage surrounds a perimeter of the flat assembly.
