Project Motivation
Problems using traditional welding masks
Homogeneous light reduction - environment not visible due to high attenuation
Welding seam hardly visible
Welding machine settings not accessible during welding
Actual electrical parameters not available for welder
Project Objectives
|
Design an intelligent welding mask
for the welding observation |
Effects
 |
Improvement
and augmentation of visual information |
|
Image and parameter documentation for weld inspection |
Image Acquisition
 |
Using two HDRC cameras(High-Dynamic-Range CMOS)for
stereoscopic representation
|
Image Processing and Augmented Reality
|
Using wearable
computer(embedded PC) |
|
Improve the contrast and brightness in the environment
of the welding scene, while preserving the image properties in the welding arc area |
|
Extract additional data from images: dimension and shape
of the welding arc, identifcation and tracking of the welding seam, workpiece, position and inclination of the
welding torch and welding speed |
Welding Quality Documentation
|
Using a stationary PC |
|
Acquire welding parameters from the welding power supply
(welding current, voltage, wire feed speed), send data to the user via wireless LAN and elaborate documentation |
Generate and Display Images
|
Using a stereoscopic Head-Mounted-Display |
|
Merging of extracted information with welding machine
parameters |
|
